RE: [opensuse] server can ping local network & net, local network can't ping it
This is very odd. What might be happening? Is this a home network, small business, or corp?
Business
Something has changed on your network... routing issue... duplicate ip address somewhere... something. Are all the machines on the same subnet?
It is specific to the machine. Can't ping it from any subnet on the network. It had a static IP on one NIC, and I configured a secondary NIC with DHCP. Both cannot be pinged from the network.
Someone may be masquerading as your server...
Its internal so I doubt that.
Did you try pinging from different machines? different subnets?
Can't ping this server from anywhere on either of it NICS (static ip address nor DHCP address). What is odd is it can read the webpages from a local network website, but the website server can't ping the server's IP addresses. ~James -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Try this: su - -c "traceroute ip_address" Does the traceroute tell you anything different? Often the NIC itself returns the ping... in fact... I have two machines on my network that return a ping when they're powered off... because the NIC still has power. It would seem that the machine has been "changed" intentionally or unintentionally to swallow the ping requests. Somebody is playing with you.... obviously. -- Kind regards, M Harris <>< -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

If you have multiple subnets and this server didn't have multiple IPs assigned from each subnet, a device(s) is(are) acting as a router(s). Forget about the other subnets but use a pc in the same subnet to test this. Try /sbin/ifconfig at the server to make sure the interface is there, as well as to see its MAC address. And, try /sbin/arp at the test linux pc (if it's a windows pc, arp -a) in the same subnet to see if it can get the server's MAC address. You may need to ping again the server to see that. By this point, you would have a good sense which part is not working as it should.
