Everything appears normal in the FTP server’s log:
fr01-srv proftpd[5591]: 192.168.0.1 – USER testuser: Login successful.
However, in Filezilla things are different:
Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing
Does the login to your newly installed CentOS 6 VPS using Virtualmin and ProFTPD fail?
Check your /var/log/secure for errors such as this :
proftpd: PAM unable to dlopen(/lib64/security/pam_stack.so): /lib64/security/pam_stack.so: cannot open shared object file: No such file or directory
proftpd: PAM adding faulty module: /lib64/security/pam_stack.so
If you are logging the above error your /etc/pam.d/proftpd was updated (incorrectly)…
