FTP logins hang while waiting for a “connect response”. I’ve read it’s PROBABLY a problem with the firewall or routing (DNS, routing, and everything else seems to be fine for all other services). From a remote client I get
Status: Resolving address of ns2.domain.com (ns2 is a virtual web host)
Status: Connecting to xx.xxx.xxx.xx:21… (this is the right IP)
Status: Connection established, waiting for welcome message…
Error: Connection timed out
Error: Could not connect to server
BUT: when I use a LOCAL client trying to get TO the machine FROM the machine I can’t connect to I get a couple of KERBEROS messages that make me think that just perhaps the problem is somehow an authentication or ftp program setup issue:
The config file is exactly the same as one on a different machine on a different network… but that machine works… so would that seem to indicate to you that the problem is the firewall settings?
if the FTP service is up…
is there anything in the iptables that indicates the port is closed or that IP’s are blocked?
is this in the config or do you actually use Kerberos?:
Use pam to authenticate (default) and be authoritative
