Hello I've had a cipe vpn in place for almost 2 years. I've had a few intermittent problems with ftp, one going on right now. My main "hub" cipe system is an older box running cipe-1.3. This box also runs firewalling and masquerading for a small network. I've got numerous boxes connected to this one over the internet, some cipe-1.3 all the way up to 1.5.2 (with the bug-compatible enabled). The problem I'm experiencing is in ftp authentication. If I try to ftp to a system over a cipe link (whether the systems are 1.3 or 1.5.2), the server's ftp banner comes up after about 30 seconds, but I don't get a login prompt until almost 3 minutes later. It's not a dns issue (all relevent hosts have entries in /etc/hosts on all systems) and I've disabled AUTH lookups by the ftp server. Plus there is minimal load on the system. If I ftp straight into a machine (not over cipe) I am immediately connected. What's strange is that this has happened 4 or 5 times in the last few years, usually happens for about 24 hours, and then goes away. I can't see any rhyme or reason to it. All other connections (http, ssh, etc) do not experience this problem. Anyone experience anything similar? -- Adam Haeder Technical Coordinator, AIM Institute adamh,AT,omaha,DOT,org (402) 345-5025 x115
