Comment 1 Bernhard Rosenkraenzer 2001-09-27 16:04:09 UTC
Works for me... Any odd firewall settings, proxies, IPv6 tunnels or the likes?


Comment 2 Bernhard Rosenkraenzer 2001-09-27 16:05:56 UTC
The backtrace looks a lot like memory corruption... There's no reason 
whatsoever why an ftp client would issue commands

PWD
your@address

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



Comment 3 Kjartan Maraas 2001-09-28 08:44:33 UTC
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 15:21:47 UTC
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 11:30:53 UTC
Never seen it again. Closing.
