I had a very strange issue today.There was a linux server that had been working for some time and suddenly the developer team suddenly started facing connection drops.they also noticed that whenever the ping ttl was 63 it was working fine. When it switched to 127 it started dropping.
I was left clueless because in /proc/sys/net/ipv4/ip_default_ttl was 64 only and there was no reason why it showed 127 in the ping .
Well finally the problem was somebody else had given a new windows machine the same ip .Whenever traffic hit the windows machine it was returning 127 as the TTL and hence all connections to services on the linux server was dropping.
The ip was then changed on the new machine and then the services connected happily ever after...............................
