Bug 334855 – net-ftp/proftpd-1.3.3a unable to set default root directory

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Mikko C. 2010-08-27 19:11:56 UTC]

After I upgraded to proftpd-1.3.3a none of the users on my server are able to login anymore.
No problems at all with proftpd 1.3.2d. No configuration changes.
See attached server config file and log.

This should be the relevant part:

Reproducible: Always

I forgot to mention the USE flags I compile proftpd with.

* net-ftp/proftpd
    Use flags: (acl) (-authfile) (-ban) (caps) (-case) (-clamav) (ctrls) (-deflate) (-doc) (-exec) (-hardened) (-ident) (-ifsession) (-ipv6) (-kerberos) (-ldap) (-mysql) (ncurses) (nls) (-pam) (-postgres) (-radius) (ratio) (-readme) (-rewrite) (-selinux) (sftp) (shaper) (-sitemisc) (-softquota) (ssl) (tcpd) (-trace) (-vroot) (-xinetd)

Fixed by removing "DefaultRoot   ~" from config file.
