================================================================ Dear Bug Team! Summary: I am unable to use open-network-stream to connect to localhost on this Linux box. I keep getting errors that look like this: "localhost/`~^H& Servname not supported for ai_socktype" I originally encountered this trying to use the Allegro Common Lisp emacs interface. I discussed the matter with them, and we narrowed it down to an xemacs problem, and a new one to me, since I have been using their interface for several years on Xemacs. I was able to replicate the error in a minimal way using netcat. First, I set up a listening port: nc -l 12000 then I do (setq foo (open-network-stream "fooproc" nil "localhost" 12000)) and I get the error. I have checked, and I am able to connect to the listening port, and send data, using netcat. this suggests to me that this is not just some dumb firewall problem. I was able to replicate this error both with the xemacs distributed by Mandrake with my distro, and with an xemacs that I built myself there, so I don't believe that it's just Mandrake (Mandriva) not packaging it correctly, either. But it could be a problem with some library installed with this distro. I did what I could to track this down myself, but I'm afraid I got lost in the C...
