linux - Traceroute: target doesn't acknowlege packet just from a specific host. Traceroutes from other hosts work fine. Ping works fine from all hosts -

-

so bit puzzled this. of in larger corporate network, machines on site.

we have 1 machine (linux) sending soap requests other machine (windows) , since few days these requests fail after time. haven't found pattern requests fail (doesn't seem particular request).

we tried traceroute requesting machine target machine , target machine doesn't acknowlege packet (asterisks @ target). running ping did work , did not drop packets.

the target machine vm on host hosting many machines.

the problem started after scheduled restart few days ago.

our team responsible application on target server, invested in helping pinpoint problem.

apart running wireshark on target server , looking traceroute or soap packets, there other point of failure can investigate?

if using domain names (not ip), check resolved properly. isp dropping packets not issue since on site.

ping works, assume both machines see each other on network. should sending machine (linux) send ping sure machine isn't blocked somewhere in network.

ping works, traceroute doesn't, check possible firewall issues. check if request not getting windows machine or reply isn't getting out.
