problems in debian sarge with network interfaces configuration
Hello all I am new here and I haven't ever posted before so I hope that this is indeed a valid network question for this forum. If not please feel free to relocate it.
I have a Debian server that is setup with 4 different network cards. One is connecting to the public internet with a wan ip address for a monitoring application that I use on a dedicated T1. The other is connected to my VoIP network, (Same T1, different Internal LAN) for tftp, xml directory serving and so forth to my cisco 7960 phones. I also have a 3rd and 4th which are on another fiber optic network and are connected to two different VLAN's managed by a cisco 1841 router, one for LAN and the other for WLAN for radius authentication purposes.
Regardless of the setup though, I cannot restart my network over ssh without getting kicked off of this server and locked out. I keep having to drive to my office and restart it manually. Now I have been working on these things for many years and haven't ever had this problem, I currently have a datacenter with over 100 linux servers in it and I can restart their networks over and over without ever getting kicked off. Does anyone know why I cannot do this with this particular Debian Server?
I have IP tables controlling all of my routing rules, firewall rules, policys and protocols, but I do on all of my other servers too.
Thanks in advance for any ideas. I could be overlooking something stupid in a configuration file. If there are any additional details needed just let me know.
