We have a nasty problem from one of our servers:
- HTTPS traffic to a server in a remote datacenter is blocked from a specific server in our datacenter
- same URL works without a problem from all other servers in the same datacenter
- PING, TRACEROUTE and MRT all stop somewhere in the remote datacenter
Our datacenter admins say that the problem is on the remote datacenter, while the remote datacenter says that there are no blocking rules for that IP!
We are stack! I need a way to prove both where the problem is, so I can force them to fix it! Is there a tool out there that can trace the HTTPS (or other to a specific port) and let me know on which server it really stops? Server runs on CentOS 5.4, if that can make any difference. No firewall or other networking blocking software is on that server - at least for the moment!
Thank you in advance
