Re: (ASCEND) Windows/Unix Ping and Pipelines
This sounds like a filter/firewall is on one of the pipelines. some Unix
pings are a little bit different to microsoft pings. while microsoft always
uses ICMP packets to ping, some flavors of UNIX send UDP packets as Pings.
I found this out playing with a firewall that was only blocking Microsoft
Pings.
