vsftpd problem: 500 OOPS: vsf_sysutil_bind

chuck_cts · 10-11-2008, 12:16 PM

everything was working till few days ago, but I can't find what could mess up vsftpd since I was only recompiling php to use gd libraries (instaled libpng, libjpeg and recompiled php).

I can login both locally (localhost or ip adrese) and remotely to ftp server but I can only use ftp locally
when I login remotely after LIST command there's error: 500 OOPS: vsf_sysutil_bind and ftp client reports it's disconnected

I've looked at logs but nothing

The FAQ says Vsftpd-1.2.1 should sort out the "500 OOPS: vsf_sysutil_bind".

chuck_cts · 10-13-2008, 02:25 PM

I know that, it was 2.0.0 or 1.2.2 version while it was working, and i've tried latest 2.0.7 but nothing

I've tried just to run 2.0.7 version with default confing after compiling and same error

edit:

some1 did something

port 20 seems to be locked/in use
but i can't figure out what's using it (i see it's sshd but can't find how it's locking it)

lsof -i :20
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
sshd 2867 root 3u IPv4 6158 TCP *:ftp-data (LISTEN)

edit2:
finaly remembered to try telnet localhost 20
found problem, some1 (there are 2 more ppl with root access) instaled psyBNC on port 20

just moved it and everything works

Good thing you found out what was causing this.
Bad thing somebody with root acount access installed psy.
Revoking permissions would be my first action.
