TNOS Release Notes - Release 2.20
Brian A. Lantz, brian@lantz.com
v1.00, 05 October 1996
These are the DRAFT Release Notes for release 2.20 of TNOS. Hope-
fully, this list of changes will give you an idea of the scope of work
that has occured since the release of TNOS 2.10.

______________________________________________________________________
1. Bug Fixes
The following bugs have been squashed.
o Fixed FTP put security hole (UNIX)
If creating a new file, the directories write permissions were not
being used to determine whether or not the action would be
permitted.
o AXUI callsign buffer expanded in size
o Fixed a buglet that crashed the system w/long nickname in convers
Only occurred with a LONG nickname when executing the '/cut'
command. Obscure, but there.....
o Fixed a few assorted buglets that weren't reported before 2.10 :-(
o Fixed crash if corrupted wpages files are expired
o Fixed a subtle bug affect the pathname() function
This only affected 'finger' when using the '-d dirname' command
line option, and then not always.
o Fixed a minor problem with forwarding using an area rewrite
If multiple messages were being sent during an FBB or XFWD bundle,
then only the first address was being rewritten......
o Fixed problem with a CC: to a public area
If you send a 'SP' BBS message (or 'SC') and end up with a CC: to a
public area it has an 'X-BBS-Type' line defining it as personal,
when it should be bulletin. This only is examined when forwarding
PBBS traffic. There used to be code in TNOS (from JNOS) that made
the 'X-BBS-Type' line *the* authority on the message's type. Now,
if a message is in a public area, it is a bulletin, and the 'X-BBS-
Type' value is ignored (i.e. a 'B'ulletin will not be changed to a
'P'ersonal). If it is public, it cannot be personal. This does NOT
prevent having the reverse, that is messages in private areas
(maybe a private storage area for an individual PBBS's forwarded
messages) being sent as bulletins.
Also, in doing this, I noticed that you COULD have a message in a
'nts' area that sometimes would NOT be sent as a 'ST' message. This
was also fixed.
o Fixed displaying parameter strings with a '\r'
Now, if you define a parameter string (like 'ax25 bctext') to be a
multi-line string with a '\r', the output to the screen or the
remote user will be as expected, i.e. it will look the same as
'\n'.
o Fixed problem with 'editheader' and messages without a X-BBS-Type
o Several unreported RIP bugs found (in LINT'ing) related to
broadcasts
o Fixed where some HTTPPBBS accesses weren't removing 'users' when
done
o Added a fix for supressing Polled Kiss polls on multidrop kiss
o Fixed convers compatibility problem with NON-TPP servers
If the callsign/nickname combo's is larger than 9 characters, this
will prevent a Jnos host that is linked in from hearing what that
person is saying. Now when speaking with a non-TPP compatible
system, the nickname should be striped off (if one was set) before
passing the data to the brain-dead server.
o Fixed an evasive buglet in FBB forwarding code
At times, after sending a transaction, TNOS would send another one,
without allowing the remote side to take their turn. Though this
has happened since FBB forwarding was added, it happened so
infrequently is was hard to pin down, and even when spotting it,
there didn't seem to be a pattern to it. Well, there was ;-) It
turns out that if all messages in the negotiation bundle were
rejected, that's when this occurred. The first line of the remote's
negotiations would get eaten, and then TNOS would start a new
negotiation, in which it THOUGHT that the remainder of the remote's
negotiation was an invalid response. All fixed now!
o Fixed a rare bug with the at command
o Fixed a kiss trace buglet, for multidrop kiss
o Fixed buglet where some forwarded personal messages weren't
deleted
They were removed from the forwarding queue, but not marked as
deleted messages This only affected FBB and XFWD sessions. This
normally didn't happen, except when a message was rejected, for
whatever reason.
o Fixed a discovered memory leak with FBB and XFWD sessions
o Forward file locking fixed
If a record got added into a *.fwd file when a forwarding session
is concluding, sometimes the new record STILL got missed, and the
*.fwd file would get deleted, losing that new record. Only happened
if the new message was in the SAME area as the area last processed.
Rare, but needed to be addressed.
o Fixed a XFWD trace buglet, with incoming messages
Thanks to a typo, if the 'forward xtrace' is on and a new message
comes in, there was a crash.
o Corrected occasional delay in noticing new messages in PBBS queues
While not bad previously, new messages MIGHT not have caused an
immediate rescan of the queue on the very next negotiation for FBB
or XFWD sessions. Now this should always rescan on the next
negotiation.
The net result is that (for example) if a new personal message
comes in on one forwarding session that is queued for another PBBS
that is also actively forwarding, then that message will go out on
the next negotiation (assuming that you have the personal areas
located before the public areas in that PBBS's forwarding entry in
the 'forward.bbs' file).
o Added Gareth's fix for incomplete nntp file crashes
o Fixed a parsing bug with incoming XFWD sessions
o Fix for possible string overflow during command line expansion
o LONGSTANDING DNS buglet found!
The DNS code had a subtile bug, which allows overrunning a buffer
if the address being queried returned a LONG response. This only
occured if the DNS was serving for others, and NOT for local usage.
This one probably accounted for the assorted DNS quirks, as well as
some (possibly ALL) of the strangely corrupted memory problems.
For example, if you queried a TNOS site (connected to the Internet)
for the address 'mx1.compuserve.com', then you would PROBABLY would
have crashed the system, 1 out of every 3 or less attempts. But a
query on a simpler address (such as 'lantz.com') would NEVER crash
it. The 'mx1.compuserve.com' address returns *10* 'A' records, and
uses about 2K of space to store it, when previously only 1K was
being allocated.
If your 'domain dns' is off, this would NEVER affect you. It was
not in the mainline DNS code, just in the code used when TNOS was
acting as a server for others.
The original RFC stated that 512 bytes should be the MAX that is
returned in a DNS UDP packet, but this seems (at a quick glance) to
be being ignored (deliberately or accidently) by every server I
checked.
For the time being, this has been changed to 4K, which should be
FAR more than enough. This will need to be revisited when I've had
time to investigate whether the RFC is obsolete or not.
o Fixed a problem sending ReturnReceipts to incomplete messages
There would be a crash if trying to send a ReturnReceipt to a
message that didn't contain a 'To:' header or a 'Subject:' header.
o Fixed a PBBS 'vm' crash with more than 30 messages
o Fixed a buglet with 'smtp kick <host>'
o Fixed a longstanding startup file/DNS problem
Several commands take a hostname or an IP address. If these are
used in the startup file, they must be used with the ip address,
NOT the hostname. This is regardless of whether or not the DNS is
already configured.
The reason is that the multitude of command that call the resolver,
do so expecting that they will NOT be swapped out. This is NOT so
with the resolver, as a DNS response can take a while.
In the past, this led to a quick crash, as the commands parameters
got freed before the command was finished with them.
In this release, the restriction of no hostname usage in the
startup file remains, though now the line causing the error will
report a useful message, and a crash will NOT occur.
If you REALLY need to have a command in the startup file using a
hostname, you can (for example) do a:
nntp add ko4ks 3600 *
like this:
at now+0001 "nntp add ko4ks 3600 *"
It will delay it's action by 1 minute, though.
o Fixed incorrect paging in 'nntp read' newsgroup reader
o Fixed XFWD email 'PBBS' name and dups scanning
Previously, all received email from XFWD sessions came in as if it
came from a PBBS named 'import', since it was being processed by
the import code. Now it properly identifies the PBBS sending it.
Also, it was discovered that the setup for the import call did not
set enough options to allow the message to be properly scanned for
R: line dups, if ALTERBID is enabled. Now this is fixed.
o Fixed NNTP code that was improper in view of RFC977
If an 'IHAVE' failed, the connection was aborted. RFC977 states
that if a server has a problem with an 'IHAVE', it can report an
error, or just drop it silently. It should NOT need to abort. And
all xNOS NNTP servers would have then gotten into a loop, as an
aborted session did not update the 'poll' files polling time. This
would NOT remove the erring message from those that it would try to
send (unsuccessfully) next time, in a loop until humans intervened.
Aside from that, aborting due to a single rejected posting (via
IHAVE) is NOT efficient, as the two sites MAY only connect once or
so a day. Postponing VALID news articles because of one INVALID
one is not acceptable. If PBBS forwarding aborted a session due to
rejecting a single message, SYSOPs would be screaming ;-)
The loop had already been found and fixed in this TNOS release, but
now the bad message sent via 'IHAVE' will not cause an abort.
o Added incoming negotiations from XFWD to log file (an oversight)
o Added code to delete incomplete PBBS messages from forwarding
queues
If the forwarding code sees a message without a 'To:' and 'From:'
field, then that message is deleted from the forwarding queue.
Previously, this message could not be forwarded (obviously) but it
also did not get removed from the forward queues, without sysop
intervention.
o FOUND THE ELUSIVE "gateway no-timeout disconnect" bug!
o Added a few pwait()'s to the fwding code, it was greedy at times
o Also refresh 'pbbs tdisc' counter during gatewaying for incoming
data
o PBBS gatewaying now yields to 'pbbs maxtimer' setting, if used
o All the above items included in beta release 2.20b1
o Fixed NNTP buglet with multiple "GMT"s in a NEWNEWS command line
o Fixed NNTP bug in code gatewaying PBBS->NNTP messages
o Fixed a bug in the IMPORT code
o Fixed an FTP server buglet (in Unix)
The security patches weren't complete, and you COULD do an 'ls' on
a directory which didn't allow reading in it's permissions.
o All the above items included in beta release 2.20b2
o Fixed a buglet in the NNTP code that could trash the 'domain
trans' setting
2. Improvements and Enhancements
The following optimizations and improvements have occurred.
o Added a 'security createsecure' command, for securing new file
creation
This boolean command sets whether the 'security createperms',
'security createuid', and 'security creategid' commands are to be
used.
o Added a 'security createperms' for new file creation permissions
(UNIX)
o Added a 'security createuid' for new file creation user ID (UNIX)
o Added a 'security creategid' for new file creation group ID (UNIX)
o Added a 'MINIDLE' attribute to the PBBS forward.bbs for each entry
For each BBS in the forward.bbs file, their MINIDLE attribute is
set to the value of the 'forward minidle' command. This value can
be overridden for each BBS by setting it's own 'MINIDLE' attribute.
This allows you to set some BBSs with short retry intervals, while
other ones can be set with long intervals. By using this, and
setting the 'forward timer' to a short value, you can have
different connection intervals for each BBS.
o Added to forwarding, code to limit time of fwding session
o Added a 'forward limittime' command to set default max session
time
o Added a forward.bbs LIMITTIME attribute to override default
o TNOS/DOS no longer supports BorlandC - Now uses DJGPP!
Many reasons for this change:
1. This is a FREE compiler
2. It is easy for anyone to acquire
3. It is the MSDOS port of the GNU C compiler, so the same compiler
will be used for both Unix and MS-DOS compiles.
4. The source tree will be able to be simplified
5. It contains its own DOS extender, allowing a linear memory map
(no 640K conventional memory limitation)
6. It will use as much memory as you have, as long as you have a
memory manager that supports DPMI (and a free one is available
for use with DJGPP applications)
7. TNOS/DOS users will be able to compile in EVERYTHING that they
want! NO MORE 'DGROUP exceeds 64K' compiler errors.
By the time this release goes public, all you need to know will be
put together to make it painless for the user or the individual who
WANTS to compile their own. There will be no NEED to compile your
own, though.
And as of this release, I WILL resume making production MS-DOS
executables available, though only one will be supplied, with most
everything compiled.
And Team TNOS will be MORE than glad to do custom compiles for
those who wish a smaller executable, if needed. Custom compiles
with DJGPP are no more effort than under Unix.
Some Borland-specific code has already been removed, and more will
soon. TNOS is now a BorlandC-free zone ;-)
o Added a 'forward reload' command
This should allow a way to eliminate the occasional crash if a BBS
was added or deleted from the 'forward.bbs' file and the system
wasn't aware of that change. This is NOT needed for changes within
an already defined PBBS in the file, but should be executed when
PBBSs are added or deleted to a running system, as soon as the
change is made.
Using this command also clears the 'forward laston' times and will
affect the 'forward minidle' and MINIDLE attributes for the PBBS
defined in the forward.bbs file. None of these is terminal; this is
mentioned as a caviat.
o Added logic to forwarding code in determining if BBS is connected
Previously, if a user was connected to the PBBS with the same name
as an outbound forwarding BBS, the session would be skipped, even
if this was the actual USER of that remote BBS visiting your
system. While that USER was connected, traffic would backup on your
system. This also was the same if the remote BBS used your system
to gateway to forward to another system.
Now if the USER seems to be on the system, the data from that user
is analyzed to see if we have received a PBBS SID. If not, then
this cannot be a forwarding session (at least, not yet), and the
outbound connection is allowed.
While their is the outside chance of an inbound and an outbound
both occuring at the same instant, they would be no problem in that
happening.
o Added PPPIPIP option 3, for use with Windows NT servers.
o Added a 'pbbscmd norreceipt' command to disable ReturnReceipt
responses
o Added expiration of NNTP newgroups New commands are:
nntp expire articles <expiry in days> (default 28)
nntp expire bids <expiry in days> (default 56)
nntp expire now kicks the nntp expire process into action.
The first two determine the age of articles and bids to be expired by
the 'nntp expire now'.
To do the expiration automatically at a set time, add a cron entry for
it.
o Added a 'nntp rline' command - Thanks Gareth
Determines whether R: lines are preserved when moving PBBS messages
to NNTP. When off, R: lines passing through the pbbs->nntp gateway
are stripped of their R: Lines, and the BBS callsigns are added to
the Path: line.
When on: R: lines are left in place, and BBS calls are not added to
Path.
The default is on. The R: line stripper only operates on bulletins
gatewayed from your PBBS areas on your TNOS.
o Added a 'forward biduknos' command
This (if enabled) will create local bids of 'xxx_<host>@hamradio'
rather than 'xxx@<host>'. For messages forwarded in via PBBS
forwarding, the bids will be 'xxxxxx@hamradio' rather than
'xxxxxx@<remotebbs>.bbs'. This is for compatibility with UKNOS,
which does it different than all other NOS's.
o Added code to reject messages with non-ASCII addresses
Since the PBBS spec makes these required to be ascii, TNOS will now
reject all non-ascii to and from addresses, and BIDs. Some were
received here with both callsigns as 6 '0xff' characters and all
the data characters were the same. Now those invalid messages will
be refused, at least with FBB-style forwarding.
o Added two NNTP subcommands 'nntp pbbs2nntp' and 'nntp nntp2pbbs'
Each of these command determine whether or not one side of the new
NNTP-to-PBBS gateway is active. If 'nntp pbbs2nntp' is on, then all
PBBS bulletins and selected personal messages will be gated into
NNTP. If 'nntp nntp2pbbs' is on, then most NNTP messages will be
gated into the PBBS message areas
The PBBS-to-NNTP handling uses a 'etc/news2mail' file. The format
is:
news.group.name toaddress [ distribution ]
Any amount of white space can separate any of the fields, and comments
can be placed in that file by using a '#' as the first character on
the line. Blank lines are also ignored.
If the user part of the address (part before the '@') is found in the
file as one of the 'toaddress' fields, then the message will be sent
to the 'news.group.name' on that line. If an optional 'distribution'
is given, then it will be used rather than the default (discussed in
the next item). The 'distribution' string (if given) must be the
complete distribution name. If the 'distribution' is '-', then the
distribution will be created as described in the next paragraph.
If the address is NOT found in the 'news2mail' file and it is NOT a
personal message area, then a newgroup name will be made by appending
the user part of the address to 'ampr.bbs.'. If a host portion of the
address was given (the part after the '@'), then the distribution will
be 'bbs.' with the host portion appended.
Personal messages CAN be gated from PBBS to NNTP, but only if they
have an entry in the new2mail file. A typical entry would be:
ampr.mailbox.sysop sysop -
All PBBS forwarded messages with a 'Message-Id:' ending in '.bbs' will
be converted to <BID@hamradio>, to accommidate for consistency in
Message IDs, and to prevent dups.
NNTP-to-PBBS gatewaying uses the same 'news2mail' file, placing
messages into the PBBS if they are found in that file. The 'toaddress'
field is used as the user name and the host part of the PBBS address
is the last portion of the distribution header line in the news
article.
If the NNTP newsgroup is NOT found in the 'news2mail' file, but the
newsgroup begins with 'ampr.bbs.', it is gated into the PBBS, using
the last portion of the newsgroup name as the user portion of the
address and the host part of the PBBS address is the last portion of
the distribution header line in the news article.
Message ID's of news articles ending in '@hamradio' will be changed to
'@nntp.bbs'. All other message ID's will remain intact, and will be
treated by the PBBS forwarding code as it always has.
All news articles NOT in the 'news2mail' file that do not begin with
the 'ampr.bbs.' prefix are NOT gated into the PBBS.
o Added a 'nntp defaultdist' command
This sets the default distribution used by PBBS-to-NNTP gatewaying,
if the address has a matching entry in the 'news2mail' file and
does not specify a specific distribution. This has no effect on
messages not found in the 'news2mail' file or on NNTP-to-PBBS
gatewaying.
The default for this is 'bbs.www' for worldwide distribution.
o Added a 'nntp trace' command - with some activity traced
o Added a pre-defined 'fwd_queue' finger target
Provides the same info as the Command Session 'forward summary' or
the PBBS 'if' commands.
o Added a NNTPFILTER compilation flag
This uses the 'etc/wordhold.dat' file (the same one as for
HOLDMODS) to record words that are unacceptable for NNTP articles.
Any incoming articles (POST'ed or IHAVE'ed) will be checked against
this list (if the NNTPFILTER flag is compiled in), and if any are
found, then the article will be dropped, reporting the error.
This is a long needed addition to the NNTP server, with the Amateur
licensing regulations varying as much as they do from country to
country!
o Added another NEW feature, that COULD be interesting!
Added an new server, which can be used in many different ways. I
like these kinds of additions, as I know that users will find many
ways to use this that I never could have imagined! (Like the
Tscript language)
There is now a FIFO server (sorry, TNOS/Unix only), which (when
started) creates two fifos, and input one and an output one. You
can (from Unix) feed commands to the Command Session via TNOS's
input fifo, and if output is generated from the command, you can
read it from TNOS's output FIFO.
The FIFO to input commands into TNOS is 'spool/fifo_in' and the
output FIFO from TNOS is 'spool/fifo_out'. You start the FIFO
server with a simple 'start fifo [trace]'. If the 'trace'
parameter is omitted, then diagnostic tracing to the Command
Session is disabled. You stop the FIFO server with 'stop fifo'.
This came from my getting tired of occasionally needing to restore
the parameters to a KISS TNC, when minor power outages occur (the
computers here are all on UPS's, but the TNCs are not. It gets to
be a regular occurance in Florida, during thunderstorm season. I
got tired of having to do a 'grep param' on my autoexec file,
grabbing it in my paste buffer with the mouse, toggling to the TNOS
Command Session, and pasting it. I wanted an easy way to send the
output of the 'grep' directly into TNOS. This can do that....
Reading TNOS's output FIFO can be a bit confusing, if you are
dealing with an application that partially buffers input queues.
The 'tail -f' SHOULD work, but doesn't (unless you 'stop fifo' from
TNOS). But a simple 'cat /nos/spool/fifo_out' works fine.
o Added a new "-m" command line option, to display Feature Flags
info
This option simply returns a hexadecimal string, representing the
compiled feature flags of that executable, then it completes
execution. This hex string contains one bit for each compilable
flag, which is set if the Flag was set, or cleared if the flag was
cleared. This can help simplify reporting which features are in an
executable.
o Added a new executable, 'tnosmap', which decodes the '-m' output
The output of this simple executable is a list (one per line) of
all the compiled Feature Flags for the given string. This
application can either take a single hexadecimal string, or the
actual output from the 'tnos -m' command, which is the hex string
preceeded with a label.
Unix users can easily tie this command to the previously mentioned
option, using:
tnosmap `tnos -m`
o All the above items included in beta release 2.20b1
o All the above items included in beta release 2.20b2
o Added the FORTH interpreter code from SM0RGV Not sure how useful
it will be, but you can compile it in! ;-) The forth.c file
compiles with two warnings, though.
o Added a new conditional processing directive to forward.bbs syntax
This new one, 'if DAYOFWEEK = xx' or 'if DAYOFWEEK = xx-yy' can
allow you to limit sections of a forwarding entry to only certain
days of the week.
3. Minor Changes
The following minor changes have occurred.
o Added code to set newly created files owner, group and permissions
(UNIX)
This is for both FTP 'put's and PBBS 'uploads'. Owner is set to the
value of 'security createuid', group is set to the value of
'security creategid', and the file's permissions are set to the
value of 'security createperms', *IF* the 'security createsecure'
command is set to 'on'.
o Renamed the 'security ftpuid' command to 'security accessuid'
o Renamed the 'security ftpgid' command to 'security accessgid'
o Added code to the PBBS download command to also honor security
(UNIX)
The 'security accessuid' and 'security accessgid' values are used
(as with the FTP server) to determine whether or not the user has
permission to download the file, based on the UNIX file
permissions, as they pertain to the secured user/group
o Removed the 'dump' command from UNIX version
Easy way to core dump, and anyway, who REALLY would use this with
GDB around ;-)
o Added a new flag 'STRICT_HTTPCALL' for enforcing valid calls
w/HTTPPBBS
o Added use of security 'amprperms' and 'nonamprperms' w/HTTPPBBS
o Added a PBBS 'motd' command, to redisplay the 'pbbs motd' string
o Added code to the PBBS forwarding to prevent useless outgoing
connects
It the past, if there were messages queued in the forward file for
a PBBS, but they were all still being held for sysop review or all
of them were deleted messages, then a connection would be made,
even though there was no traffic that would be outgoing on that
connection. This made it work like a polled connect, but was
actually an unwanted outgoing connection. Now these useless
outgoing connects are suppressed.
Also added code in that section to remove the '.fwd' file if all
the remaining entries in the queue are for messages already deleted
from the system.
o Added code to help prevent crashes when parsing a corrupted
domain.txt
I don't know if this will prevent all of the problems, but many
sources of problems when parsing a corrupted domain.txt file have
been caught. When these cases are found, a message is logged to
the log file, to help find the problem, listing the kind of DNS
line it encountered that had the error.
o Several more files LINT'ed
o Added a 'smtp kick' at end of outbound forwarding sessions
o Added code to append 'ampr.org' to abbreviated hostnames in PBBS
'send'
This applies to email addresses like 'ko4ks@ko4ks'. When seen, the
address will properly be changed to 'ko4ks@ko4ks.ampr.org', so that
rewrites that treat SMTP addresses differently can act properly.
See next entry!
o Added 'pbbs maildomain' command
Depending on the system, some TNOS machines prefer SMTP connections
(if possible) and others PBBS connections. This command allows you
to override the default (of PBBS addressing) and lets DNS hostnames
be used instead.
This only comes into play for addresses like 'user@host'. In cases
like that, the 'host' portion of the address is looked up in both
the white pages and the DNS (as 'host.ampr.org'). If only one gets
found, that one will be used. If BOTH are valid destinations, then
this command will be used to determine which one is used. If 'pbbs
maildomain' is on, then the ampr.org address will be what is used;
otherwise the white pages one will be used.
If a full DNS hostname is given or a complete PBBS haddress is
used, then this command is not used. The 'pbbs maildomain' command
is only used to complete the address used on addresses like
'user@host'.
o Added code to prevent a useless PBBS connection following a failed
one
If a failed PBBS session results in all remaining messages in the
queue being marked as aborted, then the next session would end up
skipping those on the first scan of the next connect (as it
should), but with XFWD (or FBB if the remote site had nothing to
send) this would result in a useless connect, as those messages
wouldn't try to get out the door at all on that session. If other
messages were in the queue, this would work as planned, but this
was a special case.
o MANY more files LINT'ed
o Added NNTP XHDR and XOVER enhancements from JNOS
o Removed all 'C' __ARGS() and __FARGS() macros from the source tree
While not noticable to the user, this cleans up the source tree a
lot. It was a lot of work, but past due.
This assumes compiling TNOS with an ANSI C-compatible compiler,
which is no longer an issue, since all TNOS support is for GCC
compilers. In this day and age, it's not really an issue, anyway.
o Added a 'chat' PBBS command, an alias for the 'Operator' command
I THOUGHT that this had been in there for a long time, but noticed
that it wasn't.
o Changed the output of 'nntp active' to two newsgroups per line
o Corrected the NNTP usage of GMT time
The NNTP RFC (977) specifies that the times given to commands like
NEWNEWS are to be in the SERVER's localtime, or should be in GMT
time, with 'GMT' appended to the string. The NNTP server could
handle incoming clients using 'GMT' strings, but would always use
ITS localtime when talking to a remote server. This is fine if both
are in the same time zone, but otherwise is wrong. Now TNOS's NNTP
server will use GMT strings when acting as a client.
o LINT'ing completed
o All the above items included in beta release 2.20b1
o All the above items included in beta release 2.20b2
o Added DNS patches from JNOS to allow CNAME responses to recurse
4. Remaining Known Bugs
The following are known bugs that will be addressed in the near
future. These may or may not be fixed before the next release is made
available.
1. The proxy server scripts do not seem to work properly
There is a problem, that is being looked into, which seems to be
related to calling scripts from within scripts (which proxy.scr
DOES).
2. None other at this time.... ;-)
5. To-Do List
The following are things on the author's 'to-do' list that are being
considered for this or a future release of TNOS. These may eventually
be done, but not necessarily by the next release.
1. Finish porting the Packet driver into the new MSDOS sources
At the moment, the Packet driver is not supported for the DJGPP
compiles. Shouldn't take too long to get ported, though....
2. Complete the spec and coding of the non-IP HTTP PBBS interface
3. Investigate incorporating into TNOS a userfs extension
This would allow *any* Linux (and possibly other Unix) program to
open a file and access certain TNOS features. For instance a
terminal program like minicom could open a device:
/tnos/connect/lan/k0zxf/ko4ks-1/813044
and do the equivalent to 'connect lan k0zxf ko4ks-1 813044'.
You could incorporate a copy of your current usage stats into a email
message in Pine, by simply inserting a file named
/tnos/stats/usage/general.
4. Add capability to allow use of OS commands
This includes finishing the incomplete 'pipe' command in the Unix
release. Due to the obvious restrictions of MS-DOS (memory, etc.),
this WILL be considered for Unix version only.
5. Add better support for PBBS<->Internet mail address translation
The 'translate' file and improved handling of aliases is a START,
but more work needs to be done here. Maybe a 'translate.out'
file...
6. Still better handling of AUTO/LOCAL ax25 routes
Improvement by making an ax25 route entry part of the connection
block, using this unique AUTO route for this connection only.
7. Support (optimization) for ncurses 1.9.x for performance
8. Color support output to Unix console
The various color commands don't work with Unix and curses.
Annoying, but just possible unexpected output. No crashes.
9. Consider adding a 'R x - x' syntax to the BBS read command
10.
Consider adding IP MASQ support
11.
Add code to allow a TIP socket type, for use with LL Modems
12.
Tweek the WPages code a bit
Need to improve the code that insures that the wpagebbs entries are
correct, of the proper length, and actually look like hier
addresses. Also, make the expiring of WPages files less fragile if
the file has become corrupted.
13.
Check into duplicate entries in the WP files
While not harmful, the WPages routines SHOULD be overwritting
existing entries, NOT creating new ones.
14.
Consider adding intelligence to convers links
The idea being that if there are no incoming links, and no local
users, that the remote outgoing link would be brought down until
this changed.
15.
Consider added auto7+ detection
