RE: Please help troubleshooting connection problem via SSH

[George Dinwiddie]

Chris,

I do not believe this is an ssh issue.  I believe it's a WinXP SP2 issue with 
CvsNT (which both WinCVS and TortoiseCVS seem to use).  I'm having a similar 
problem with these as well as with the Eclipse CVS client (which seems to be 
written in Java).

The production server is CVS version 1.11.17 and I can connect with it via SSH 
using the Cygwin CVS client (also version 1.11.17).  I cannot connect with it 
via SSH using CVSNT version 2.0.58d.

The SSH connection works fine, but the CVS client hangs.  In order to see what 
was happening on the server side, I experimented with an old CVS (version 1.11) 
setup I already had on a private machine.  I did some grepping and found 
reference to a CVS_SERVER_LOG environment variable, but that doesn't seem to be 
used any more.  It's not mentioned in the latest copy of the CVS manual and it 
doesn't seem to work.

I renamed my cvs executable to cvs-bin and wrote this shell script for cvs:

#!/bin/bash
export CVS_SERVER_LOG=/home/cvs/CVS_SERVER_LOG
echo "========================" >> $CVS_SERVER_LOG
date >> $CVS_SERVER_LOG
echo cvs $* >> $CVS_SERVER_LOG
echo "------------------------" >> $CVS_SERVER_LOG
cvs-bin $* | tee -a $CVS_SERVER_LOG

When I execute Cygwin's cvs, I get this on the client side:

C:\Program Files\cvsnt>c:\cygwin\bin\cvs -t -t -t -n co myproject
 -> main loop with address@hidden:/home/cvs/projects
 -> safe_location( where=(null) )
 -> Starting server: ssh -l user host cvs server
address@hidden's password:
S-> do_module (myproject, Updating, , )
S-> do_module (myproject, Updating, , )
cvs-bin server: in directory myproject:
cvs-bin [server aborted]: there is no version here; run 'cvs-bin checkout' first
S-> Create_Admin (., myproject, /home/cvs/projects/myproject, , , 0, 0)
S-> fopen(/home/cvs/projects/CVSROOT/history,a)
 -> Lock_Cleanup()

and this on the server side:

echo "========================" >> $CVS_SERVER_LOG
date >> $CVS_SERVER_LOG
echo cvs $* >> $CVS_SERVER_LOG
echo "------------------------" >> $CVS_SERVER_LOG
cvs-bin $* | tee -a $CVS_SERVER_LOG
address@hidden bin]# !tail
tail -f /home/cvs/CVS_SERVER_LOG
ok
E S-> do_module (myproject, Updating, , )
Module-expansion myproject
ok
E S-> do_module (myproject, Updating, , )
E cvs-bin server: in directory myproject:
E cvs-bin [server aborted]: there is no version here; run 'cvs-bin checkout' 
first
E S-> Create_Admin (., myproject, /home/cvs/projects/myproject, , , 0, 0)
E S-> fopen(/home/cvs/projects/CVSROOT/history,a)
error

This is as it should be.  When I execute CvsNT's cvs, I get this on the client 
side:

C:\Program Files\cvsnt>.\cvs -t -t -t -n co myproject
  -> Tracelevel set to 3.  PID is 3620
  -> Session ID is e24419390921f88
  -> Domain found: MYWORKGROUP
  -> main loop with address@hidden:/home/cvs/projects
address@hidden's password:

and this on the server side:

========================

version

and the connection hangs.  It appears that the CvsNT client never sees the "ok" 
message from the server.

The WinXP firewall is turned off.  Any clues are greatly appreciated.
