Re: Linux 7.3 Not able to connect
first thing to check:
- ip configuration/gateway configuration
- firewall configuration
- on switch/router: vlan configuration

Re: Linux 7.3 Not able to connect
I'd also like to see the output of these two commands on the linux boxen:
iptables -nvL
ipcahisn -nvL
Atleast one of these should fail with errors.
Are you sure it isn't affected by tcp wrappers, and thus require correct entries in the /etc/hosts.{allow,deny} files, so the contents of them as well if you could.
You've also verified that they are all on the same PHYISCAL segment of the network?
Now, what service are you trying to connect to? Are you sure this service is running on the linux boxes?

Re: Linux 7.3 Not able to connect
As root, both boxes
service iptables stop
Test connectivity.
If it suddenly comes on, you are in the right ballpark, if not move on to other causes.
Same goes if ipchains if you are using that firewall.
