Can't start ProFTPd, worked fine before

[sushestvo]

Ok, I had ProFTPD running about 3 months now w/o any problems.
All the sudden yesterday when I tried to connect ftp was down. So I checked, then tried to start it. Got this back:
proftpd: - warning: AuthPAMAuthoritative is deprecated
- getaddrinfo 'discovery.lockdns.com' error: Name or service not known
- warning: unable to determine IP address of 'discovery.lockdns.com'
- getaddrinfo 'discovery.lockdns.com' error: Name or service not known
- warning: unable to determine IP address of 'discovery.lockdns.com'
- getaddrinfo 'discovery.lockdns.com' error: Name or service not known
- warning: unable to determine IP address of 'discovery.lockdns.com'
- getaddrinfo 'discovery.lockdns.com' error: Name or service not known
- warning: unable to determine IP address of 'discovery.lockdns.com'

I really I don't understand why this is happening.

I assume you have an dynamic DNS record at lockdns.com that is: discovery.lockdns.com ? Please check if discovery.lockdns.com is still active and working.

[sushestvo]

the IP address still the same. It's dedicated server with static IPs.
You can open discovery.lockdns.com w/o any problems.
Could have my domain registry changed something? But then why would it still open the address fine?

What output do you get when you execute this command on the shell on your server:

dig discovery.lockdns.com

[sushestvo]

; <<>> DiG 9.2.5 <<>> discovery.lockdns.com
;; global options: printcmd
;; connection timed out; no servers could be reached

that doesn't sound good
how do I fix this

You need a working nameserver in your resolv.conf:

/etc/resolv.conf

The vormat of the file is:

nameserver [IP-OF-THE NAMESERVER]

You may have more then one nameserver. The first nameserver shall be the IP of the server itself, if you are running BIND DNS Server.

That did it! Thank you so much!
