Hi Bryan, In the past we had seen this error on Linux when there was a mismatch (32-bit vs. 64-bit) between the system libraries and Chimera. For some reason that mismatch causes Python's call to gethostbyname (to resolve 'www.rcsb.org') to fail. There doesn't seem to be a mismatch in your case. What we would like you to do is install the 64-bit 1.3 release and see if that works. Depending on whether it does or not would determine what we would do next. As a (horrible) workaround for your problem with the 1.4 release you would edit a couple of files in the distribution and change every instance of 'www.rcsb.org' with '198.202.122.52'. The files are in <your Chimera distribution>/share/chimera and are named __init__.py and fetch.py. Let me know if that doesn't solve the problem. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Oct 26, 2009, at 7:02 PM, Bryan Krantz wrote:

Dear Chimera Users:

Does anyone know how to resolve this bug. I tried to load a PDB file from the web using the ID 3hvd.

Got this error back:

Error reading 3hvd: Error during PDB fetch: [Errno socket error] (-2, 'Name or service not known')

I am running this Chimera : Linux 64-bit chimera-1.4-linux_x86_64.exe Size: 77850528 bytes MD5: 1e05f4607699c88467e81cc249aa4ad1

My OS is Debian Lenny AMD64.

Thanks in advance for your help.

Yours, bryan
