Sounds like his flavor of *nix (and/or a driver) is automatically de-configuring the interface upon link failure/call hang-up/etc. Sven, are you using a multi-line ISDN or analog dial card? Or separate modems (serial or USB)? Or, is this actually a multi-line aDSL/cable setup, with the physical server connections being ethernet? You said "all dial-in" but some folks use "dial-in" interchangeably with "dynamic IP aDSL/cable". I'm just trying to get on the exact same page so we can help you solve this. -- Stan

The IP is static but I receive it using PPP (like DHCP) and if the DSL line is down, the pppX-device "vanishes" -> that's why no process can bind to the ip. -- Best regards, Sven mailto:sven(a)clamav.net ClamAV, a GPL anti-virus toolkit http://www.clamav.net

I never need to use smtp_bind_address when my own mailhost needs to fall back to dialup (which is fortunately rarely). All reasonable TCP/IP stacks will automatically use the right source IP address when sending out mail over the dialup link or over the local network. Wietse |
