High chances that its caused by some firewall/proxy/software thats mangling your request. If you need more help, just raise a support ticket with all the information (repository, user, etc)

I am getting this as well, has a solution been determined? I am using TortoiseSVN.

@creedInteractive since you’ve upgraded, try using SSL – that problem should go away

From experience, 80% of these sort of problems are due to some firewall/software/proxy which mangles the DAV requests

thanks, SSL got me working.

Yup – that’s usually the trick!

Due to the nature of SSL, Proxies/Security software/Firewalls don’t tend to try to “mangle” SSL requests.

I can’t checkout or commit to any of my repo’s. The last time I could was in January. I’ve tried using intelliJ 9, Eclipse 3.5 and command line svn (version 1.6.5). I’ve also logged a ticket (#9962) 12 days ago, but haven’t heard anything since. I can’t think that it’s a proxy problem because if I try via adsl at work (no, the port is open) or through my 3G at home, I get the same errors. And it was working 3 weeks ago with my 3G account. Please help.

An example of the output:
rick@hobbes:~$ svn co http://svn.xp-dev.com/svn/test-JSF-1/trunk
svn: OPTIONS of ‘http://svn.xp-dev.com/svn/test-JSF-1/trunk’: Could not resolve hostname `www.xp-dev.com/users': Host not found (http://svn.xp-dev.com)
rick@hobbes:~$

RickAvlonitis – that means there’s something wrong with your DNS server settings. Do check with your ISP.

Thank you for your reply, rs. I flushed my DNS using “ipconfig /flushdns” and set my dns server to openDNS (208.67.222.222 primary; 208.67.220.220 secondary). I still can’t check out a project from my repo :(

There’s something really weird with your SVN client – somehow its attempting to resolve the host www.xp-dev.com/users -- including the /users part

Which SVN client and version are you using ? It looks to be broken in some aspects.

I’m using command line svn (version 1.6.5).

The command: "svn co http://svn.xp-dev.com/svn/test-JSF-1/trunk" gives the error:
"svn: OPTIONS of ‘http://svn.xp-dev.com/svn/test-JSF-1/trunk’: Could not resolve hostname `www.xp-dev.com/users': Host not found (http://svn.xp-dev.com)"

Definitely something broken on either your client or your DNS resolution:

1. SVN client seems to prefer resolving the hostname www.xp-dev.com/users instead of resolving svn.xp-dev.com

2. Your DNS resolution returns a host www.xp-dev.com/users for queries on svn.xp-dev.com

Crisis is over. I just checked it out using subclipse. Thanks for your time :)
