I have a customer with a RH 7.2 server running PoPToP vpn server. They connect to the server from home using dialup internet access and print to their local printers using samba. It used to work. If I connect using my office broadband connection it still works. When I try so access their shares when they are connected using smbclient I get the "not listening on called name" error. If I do an nmblookup -A <ip> it returns the name of their pc, so I know I'm using the right name. What is going on?
