Hmm, i just gave a reply similar to this one in Tapuz's forum. Look, wu-ftp is problematic. It insists on performing DNS queries for the client at login time, but fails to act whenever it isn't needed. I'm assuming your linux box has it's DNS servers configured in it's resolv.conf file. See, when you disconnect those servers can't be reached, and the DNS queries block wu-ftpd for a while (wait a few minutes, it should then respond). Using netstat at this point *should* show you an established connection to the DNS server with the target port being "domain", although this is NOT the case in reality... Anyways, in order to see if this is the problem, comment out all the DNS servers in your resolv.conf file when you're not connected to the internet, then try to login to wu-ftp. Also, try to set the proper search order in the nsswitch.conf file, like so:
hosts: hosts [NOTFOUND=return] It could help. If this is indeed the reason, you have two choices (that I can see): 1. Install a DNS server internally to handle those times where you are off the internet (and place that as the first server in your resolv.conf) 2. Use a script to replace the resolv.conf file with a backup when you disconnect. This is the easiest solution I believe... You can have the script do the opposite when you reconnect. Maybe you can do that automatically somehow, who knows...
