[vpnc-devel] MTU detection in vpnc-script

[Miner, Jonathan W (US SSA)]

Just started using vpnc recently....

I have also run across the MTU detection issues, and found the following bug report on the Debian site:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=525389

I patched my vpnc-script by removing the DEV line, and changing the MTU line to be:

MTU=$(($($IPROUTE route get "$VPNGATEWAY" | sed -ne 's/^.*mtu \([[:digit:]]\+\).*$/\1/p') - 88))

Seems happy now, even when I don't have a default route!
