Just did a little test: - boot into runlevel 3 - login at tty1 - `cat .jackdrc` & - linuxsampler & - telnet zita1 8888 and this works perfectly. Why do you remove udev ? It does some useful things. Here it completely replaces hal for example. I'd be surprised if it has anything to do with your problem. My /dev/pts is normally empty except for the single device you mentioned. New /dev/pts/# devices are created for xterms but I assume you don't use those. Ciao, -- FA

(Here we're just checking the kernel's support for pseudo terminals as well as the support for legacy pseudo terminals). But that's the way devices are handled in "recent" kernels. And not a bad way, if I might add ... So, for debugging purposes, can you do: ssh localhost on the problematic system. Iff you theoy is correct, this should not work.

On Sun, 19 Jun 2011 13:19:36 +0200 (CEST), Julien Claassen wrote Wait, wat, wait! How did you try to telnet to SuperCollider if localhost doesn't resolve? Looks like _this_ is the problem (and has nothing to do with either udev nor pseudo-terminals at all). What happens if you add 127.0.0.1 localhost.localdomain localhost to /etc/hosts and try again?

That would report 'Connection refused'. Timeout sound suspiciously like some (dumb!) firefwall rule. Maybe 'sudo iptables -L' could give some insight ...

Are you sure linuxsampler is using the port 8888 ? ( maybe the port is taken by another program ) start linuxsampler and try the command: sudo netstat -paunte | grep ":8888" or sudo netstat -paunte | grep "sampler" --
