socket -server not accepting connection on Ubuntu/AWS

[Robert Karen]

I am porting a self-compiled tcl executable
to Ubuntu/AWS. It sources a script with socket -server to
accept connections from other
processes on the same server. However, the socket -server isn't accepting any connections. There is no error message on client nor on server side. When I try
socket -server from the installed tcl it works fine. (I can connect to it from another window via tcl command line opening a socket to that port).

Any idea what the problem could be?

If it makes a difference my original source code was compiled when using tcl 8.5 and now same source links with 8.6.

This is not run as root but is using port numbers > 25000.
Thanks for any ideas!

Hi Robert,
I would check the firewall of the server.

Are you sure that the "socket -server" code actually runs (i.e. printout
just before and after the statement)?

| There is no error message on client nor on server side.

IMHO at least the client should either show "connection refused" if the
socket is not open, or "connection timed out" if there is e.g. a
firewall issue...

Is this the same code as in your does-not-work-case above, or just wish
with manually typed "socket -server"?

Can you interactively start your executable an type "socket -server" there?

| Any idea what the problem could be?

As Harald pointed out, firewall would be the first suspect, but you
say that installed tcl 'works'...

Not sure if this combo is supported... Do you run with stubs or mean
tricks (symlink libtcl8.5.so to libtcl8.6.so)?
Gurus to the front ;-)

I didn't combine 8.5 and 8.6. just took same source code that added new commands
and on old machine linked with 8.5 and on this machine linked to 8.6.

Yes I am able to run the program interactively, run a script to run socket -server
and try to connect from another window that is logged into same linux machine. it doesn't work.
I had earlier asked sysadmin and he claims the firewall is not affecting it since its all in
same server. I thought maybe something in 8.6 changed regarding socket. doesn't sound like it.
It seems other tcl commands work ok. just a problem
with the socket. I will go back to him to double check firewall. Thanks to both of you for answering.

You could check
lsof -iTCP -sTCP:LISTEN
to see whether the server socket is listed at all. If I go

tclsh% socket -server foobar 65432

% lsof -iTCP -sTCP:LISTEN
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
wish 18361 ralf 7u IPv4 20662675 0t0 TCP *:65432 (LISTEN)
wish 18361 ralf 8u IPv6 20662676 0t0 TCP *:65432 (LISTEN)

If the socket is listed, you could use netcat (nc) to connect to it
instead of TCL.

Also there is /proc/net/tcp which seems to hold some information, too.

wireshark could be useful to see the TCP traffic once the client tries
to connect...

HTH & good luck!

I've not seen it mentioned in the other replies, but the "-server"
section of the socket manpage says this:

Server sockets depend on the Tcl event mechanism to find out
when new connections are opened. If the application does not
enter the event loop, for example by invoking the vwait command
or calling the C procedure Tcl_DoOneEvent, then no connections
will be accepted.

So, one more question: Are you entering the event loop?

[Robert Karen]

yes, I am.

[Robert Karen]

Thanks for those commands! lsof lists the socket similarly in the case where it
doesn't establish connection as when it does. nc is convenient. but it behaved as it did
when I connected via tcl console. no errors. just no connection. I will revisit firewall. thanks.

Just my $.02 contribution and a grain of salt:
How are you obtaining the server's address? Are you sure AWS gives you
the same server address you expect? If you are not using a dedicated
server, AWS may give you a different IP each time.

[Robert Karen]

I had a co-worker run strace on the socket server that was not working (my compiled program with tcl linked in) and
also on the socket server that is working from installed tcl, and diff them and it showed this: Note the lseek line that
doesn't fail for the problematics socket call:

The "<" lines are from the working run.
The ">" lines are from the non-working run.

I will attach portion of strace from the session where the socket doesn't work. Maybe a guru out there can explain the difference.
sorry about the length.

fd 1 is usually stdout, so there is a difference between your program
and installed tcl with regard to this. If you redirect stdout of your
program to say "| cat", does that change anything? (I can't imagine
however how stdout would affect sockets...)

Though I'm not a 'guru', the rest of the strace seems ok to me (opening
IP4 and IP6 socket w/o errors at the end). Would be interesting to see
the strace for the working connection in comparison, though.

That is interesting. Is it possible that some bit of C code somewhere
is closing stdout (which will result in reuse of fd 1 for another open
file.

Redirection would not change the fact that fd 1 is stdout, it simply
changes what connects to the other end of fd 1 (instead of, usually, a
terminal it instead is another program's stdin).

But yes, the stdio file descriptors should not normally impact sockets,
at least on a reasonably posix compatible system, as sockets end up in
a different 'namespace' at the C level.

Tcl does, however, mix both together at the Tcl level, so strange
goings on with stdin/stdout/stderr in C code might cause an overlap
situation to occur at the Tcl level when they get mixed together.

just a guess.

Thanks to you and others for the idea! I found these lines in the c code that somehow mess up the socket.
when I commented out these lines that redirect stderr, the socket server worked.
This is old code originally from Solaris' UNIX. Maybe I have to close stderr and open it again?

void tclserver_open_log( char *login )
{
time_t currentTime;
char file_nm[ 80 ];
char *timeptr;

currentTime = time(NULL);
timeptr = ctime(&currentTime);
sprintf( file_nm, "/log/tclserver.%s", login );

if( freopen( file_nm, "a", stdout ) == NULL)perror("Log File");
/*
*stderr = *stdout;

fprintf( stderr, "<>------------------- START --------------------<>\n" );
fprintf( stderr, "started logging at: %s", timeptr);
fflush( stderr );
*/
}

[Robert Karen]

replacing
*stderr = *stdout
with this seems to work.
dup2(fileno(stdout), fileno(stderr));

Yes, this is not the proper, modern, way to make stderr be a copy of
stdout. This is a very old, and now quite crusty, way to do this.

Using one of the dup()'s is the proper modern way, so this should
hopefully now work for you correctly.
