I am having an intermittent mail problem when my netscape clients go out through a debian 2.2 masqurading server.
The server was receintly upgraded from 2.1 to 2.2. The upgrade happened before it began service as a masq server. (No this server has never been fully operational). Symtoms: When netscape goes to 'get messages' it connects and begins getting the messages. If there are short messages, they will be received. But if there are any moderately large emails it will lock up. Usually netscape will come back and say "network connection reset by peer" When I watch pppstats it appears that when netscape begins it gets full bandwidth ~3k/s, then in between 5-25 sec it drops way down, usually 0 except for a few hits. Please help, I am really looking bad here... Setup: Netscape on win NT and 98 on network 192.168.x.x 10baseT server running ppp over 56k modem to isp. All software is loaded through dselect w/default stable directory and hand configured. Currently manually called network setup: /sbin/depmod -a /sbin/modprobe ip_masq_ftp echo "1" > /proc/sys/net/ipv4/ip_forward echo "1" > /proc/sys/net/ipv4/ip_dynaddr /sbin/ipfwadm -F -p deny /sbin/ipfwadm -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0 What I have tried Problem showed up with kernel 2.0.36 MRU changed from default to 552 in /etc/ppp/options MTU changed from default to 552 in /etc/ppp/options Recompiled and curently using kernel 2.2.17 optomize as router
