vsftpd error 530 after upgrade from oneiric to precise

[Kyle Bentley]

After upgrading my server from 11.10 to 12.04, I can no longer log into my ftp (with any user) locally or with my web address. I use a slightly modified config file, which shouldn't change much, as it was working for months before now.

removing

/etc/pam.d/vsftp

seems to have resolved the issue, but does not seem like a clean solution.

[Serge Hallyn (serge-hallyn)]

I can't reproduce this with /etc/pam.d/vsftpd in place and with a config updated to look like yours.

Do you see anything helpful in /var/log/vsftpd.log or /var/log/auth.log?

I found same bug,only in ubuntu 12.04 server X64 edition,have no in i386 edition.

[inetsurfer (inetsurfer)]

I have already reproduce this bug by install X64 and i386 edition.

removing /etc/pam.d/vsftpd worked for me also, but that makes the whole "supports pam authentication" totally meaningless, since you can't actually configure anything for vsftpd :-)

Could this be regression or something similar to this old bug from redhat?
(Comment 24 mentioning some kind of "pam module stack memory overflow" thing..)

https://bugzilla.redhat.com/show_bug.cgi?id=708657#c24

Reasoning: removing /etc/pam.d/vsftpd means actually that pam just uses the default "other" authentication, which in effect only includes the common-* things, which in turn is almost the same what the original vsftpd-file does. But looking with strace shows that for some reason vsftpd opens the /etc/pam.d/other file even when /etc/pam.d/vsftpd is in place? Don't know if it is supposed to do that or not, just an observation. In the end it seems that removing vsftpd-file results in vsftpd opening less pam-files and that could incidate that this is related to some kind of memory limit barrier..?

This sounds like bug 869684.

[Kyle Bentley (kwbent)]

Robie, that sounds like two bugs are the same. Perhaps you can merge them?
