Comment 1 Bernhard Rosenkraenzer 2001-09-27 12:04:09 EDT
Works for me... Any odd firewall settings, proxies, IPv6 tunnels or the likes?
Comment 2 Bernhard Rosenkraenzer 2001-09-27 12:05:56 EDT
The backtrace looks a lot like memory corruption... There's no reason 
whatsoever why an ftp client would issue commands


in that order. (Expected:
USER ftp
PASS you@address

Comment 3 Kjartan Maraas 2001-09-28 04:44:33 EDT
No proxy, not sure about firewalls as I'm at a conference. There seems to be
nothing special about things here. I still see this after a reboot and with the
latest kernel from the beta rawhide.
Comment 4 Pekka Savola 2002-06-22 11:21:47 EDT
This isn't related to now-fixed #47763 probably?

(At least, I'd check a bit with tcpdump.)
Comment 5 Kjartan Maraas 2002-06-23 07:30:53 EDT
Never seen it again. Closing.
