svn up problem in Debian

Hello.

I have a problem with subversion client in my computer I'm working on Debian
SID. I get a working-copy without problems from external server using http
method.

$ svn co http://myserver.com/ folder/

But when I need to update my working-copy, it appear following error message
after a 15 minutes waiting.

$ svn up

REPORT request failed on '/!svn/vcc/default'
REPORT of '/!svn/vcc/default': Could not read status line: Connection timed
out (http://myserver.com)

I do a test on another computer with Windows XP in same network, using
TortoiseSVN and here works without problems, I can update and send files.

In my Debian computer, I have a working-copy from other external server and
different project named "dojo" (http://svn.dojotoolkit.org/dojo/trunk), in
this wc "svn up" works without problems.

Any idea?

Thanks.
