I am using a Linux 2.0.33 Box to connect our LAN to the Internet and as a "Copy"-Mailserver over a dial-up connection with one (dynamic) IP. Now, since it bothered me that the first paket got lost due to changing IP on the ISDN-card I did 'echo 2 > /proc/sys/net/ipv4/ip_dynaddr'. (Which seems to work only now and then because sometimes I still get an error-message from the client. But that's not the problem.) When I start fetchmail in demon-mode or via cron it seems to timeout and never fetch any mail from the server I am polling. After I did 'echo 0 ...' everything seems to work fine. Did I make a mistake, or is it the dynamic IP? The way I use fetchmail is 'fetchmail -d 1800 -a -L /var/log/fetchlog' for daemon-mode or 'fetchmail -a -v' from crontab. TIA Sascha
