Pings to _any_ IP return 192.168.1.77 not available
Have Redhat 9 installed. New to Linux so I've been tweaking, playong and probably doing things I shouldn't. Lost internet connectivity and start looking around. Tried pinging my router (192.168.1.1) and get back 192.168.1.77 not available. Hmmm, interesting.
Lets try pinging 4.2.4.1. Response 192.167.1.77 not available. Any other IP address - same response.
There seems to be a problem here. Either I've fiddled something I shouln't have or my machine has developed some type of compulsive attachment to 192.168.1.77.
Kernel IP routing table

OK, more wierdness....
Just ran redhat-config-network, it scolded me abut running as root at least once (which I have), gave me a lot of message about permissions. So, I su'd, ran redhat-config-network and saw that my host name wntry was blank (which it wasnt before), gave it a host name, deactivated and activated eth0 - and now all seems to be working fine.
If I am not mistaken, you cannot use 192.168.1.x for your network. You have to use 192.168.0.x for your group of IP addresses (which is a reserved group for LAN/home networking)
"If I am not mistaken, you cannot use 192.168.1.x for your network. You have to use 192.168.0.x for your group of IP addresses (which is a reserved group for LAN/home networking)"
Private non routable IP addresses include: (basically these addresses will not route through the public internet)
192.168.0.0/16
10.0.0.0/8
172.16.0.0/12
As per RFC 1918
Which means that for a private network you can use
192.168.0.xxx through 192.168.254.xxx for your home networking needs. Just be sure to use correct subnet masks.
Ok, I just remember checking into this a long time ago (RedHat 6.0) and was trying to recally back to then. All I know was I went in to all of my settings and changed the 192.168.1.x to 192.168.0.x and everything worked perfect. Perhaps it was something else that got it working like ifdown/ifuping the eth again.
