I've requested that our operations team take a look (PCN8987).

Our operations group reports that they are puzzled.  We use cvsup to
keep our anoncvs server up-to-date, and it's working fine there. 
We're wondering if it's a network thing.  Stefan, are you getting this
error right away, or after some downloading?  Can you send us a
traceroute from you to the cvsup server?

we get the error immidiatly, no data transferred.

Thanks Stefan.  I'm coordinating with the operations team to
troubleshoot further.

I've gotten more feedback from ops on how to troubleshoot this.  Could
you do the following:
1. Log into the tunnel server
2. 'telnet localhost 5999' on the tunnel server (if you are using 5999
on the local machine as well; otherwise substitute your port as
necessary).  Do you get a valid cvsup response here?
3. Run your normal cvsup client with the '-L 2' option for debugging,
and send us the output.
Thanks!

telnet to port 5999 on localhost gives me a :
"Name or service not known: No such file or directory"

debug output:

Martin, how would you like to go forward?

fast, reassigned to taska

Okay, I've sent this info on to the ops folks, thanks.

Martin: when you did telnet to port 5999 on localhost, was that on
your cvsup server, or on your local machine?  What kind of machine is
your cvsup server?  (I can't get my linux box to return that error at
all.  My errors all begin with telnet:.)

I'm doing the telnet to port 5999 on the host where the tunnel has
been established. It's a Linux 2.2.16 box with OpenSSH 2.2.1 running.
The configuration hasn't changed in the last years.

We're still not sure why cvsup would be working with the anoncvs
server, but not the remote server....  But we have made a change in
the cvsup server configuration that should make ssh a bit more
friendly.  Please test to see if cvsup is working now.

cvsup works again, thanks.
Do I have to ask you/myself what the change was?

Our operations group apparently, at some point, upgraded SSH on that
machine without telling us- or possibly even each other (the SSH
version on that machine was known to have a security exploit). 
Apparently, during the upgrade, some configuration got changed, which
they restored.  So yes, the problem was miscommunication on our side.
 I apologize for that.

verified.

close issue.
