Fwd: svn problems

[rachid ayad <ra...@ut.edu.sa>]

 Dear Subversion experts, I have really a proxy/firewall problem using svn
to download a package I use it for research. I am listing here the error
message after using svn to download the software from the site here below:

***********
svn: OPTIONS of
'https://ekpbelle2.physik.uni-karlsruhe.de:/trunk/tools': Could not
create SSL connection through proxy server: Could not authenticate to
proxy server: ignored Kerberos challenge, ignored NTLM challenge,
GSSAPI authentication error: Unspecified GSS failure.  Minor code may
provide more information: No credentials cache found
(https://ekpbelle2.physik.uni-karlsruhe.de)
*************

My institute is using proxy on port 8080 and I was in contact with the
administrator but he did not solve the problem. I set the proxy and password
on the subversion servers config file: /etc/subversion/servers but is still
does not work. The administrator removed all firewalls on a port (3690) so I
used:

svn co https://ekpbelle2.physik.uni-karlsruhe.de:3690/trunk/tools

 and it did not work

 Would you like please answer me: It is important for me.

Thank you rachid ayad

 Thank you Ryan for your answer, I think is before the host password (is
since weeks I had this problem so I will try from my office) with my home
network it works fine with the host password. But it's a good question
because! is the authentification the message talks about, is from the proxy
or the host? I think the message is clear it says "could not authenticate to
proxy server". Also I inform you that when I do not specify the proxy id and
password in subversion servers config file svn hangs and when I specify it
it will not hang but immediately displays the error message below.

  thank you, rachid

I'm afraid I don't know the answer to your question, I just want to point out that 3690 is the default port for svnserve, so that's applicable when a repository is served using the svn:// protocol, which this repository is not: it's served with the https:// protocol, which means it by default uses port 443. You cannot simply pick a different port number to communicate with a server with, unless that server is configured to respond with the correct protocol on that port; this server does not appear to be configured to respond at all on port 3690, which is not a surprise.

When I try "svn ls https://ekpbelle2.physik.uni-karlsruhe.de/trunk/tools" I first get asked if I want to accept the SSL certificate, and when I accept it temporarily, I'm then prompted for my username and password; when I fail that because I don't have one, I get "svn: OPTIONS of 'https://ekpbelle2.physik.uni-karlsruhe.de/trunk/tools': authorization failed: Could not authenticate to server: rejected Basic challenge (https://ekpbelle2.physik.uni-karlsruhe.de)". You are presumably entering a valid username and password before receiving the error you mentioned above? Or does it show that before even asking you for a username and password?
