Greetings;
I've noticed recently after doing a package update on the iproute
packages I can no longer configure my tunnel interface tunl0. Mainly I'm
trying to reset the ttl to 64 for traceroute to properly work.
Everything I've searched comes up empty. Here's what I see:
root@gw:/usr/local/bin# iptunnel show
tunl0: ip/ip remote any local any ttl inherit nopmtudisc
root@gw:/usr/local/bin# ifconfig tunl0
tunl0 Link encap:IPIP Tunnel HWaddr
inet addr:44.88.0.1 Mask:255.255.255.255
UP RUNNING NOARP MULTICAST MTU:0 Metric:1
ttl is stuck on inherit and MTU autoconfigs to 0. This I know is set by
nopmtudisc however if I try to adjust things:
root@gw:/usr/local/bin# ip tunnel change tunl0 ttl 64
ttl != 0 and noptmudisc are incompatible
root@gw:/usr/local/bin# ip tunnel change pmtudisc mode ipip
add tunnel tunl0 failed: No such file or directory
Why would it try to ADD? the command is CHANGE.
Has anyone else suffered this before and if so what was the fix?
Thanks in advance.
