Cannot ping default gateway

UNIX for Beginners Q & A UNIX for Dummies Questions & Answers

I have NCR MP-RAS unix. I have been trying for several months to get our network working since we had never used it before. I have setup all routes that I can think of. I know it has something to do with the routing table, because out of sheer luck I was able to get it working, and than like a good ol computer it decided to restart and I lost my changes. Unfortunately I do not know what I changed/added to make it work. Any help would be greatly appreciated. Below is all the information I think you need. Tanks in advance.

netstat -rn
Destination      Gateway            Flags    Refs      Use  Interface
default          192.168.1.1        UGS         0        0  en2
127.0.0.1        127.0.0.1          UH          2       11  lo0
192.168.1        192.168.1.129      UGS         0        0  en2
192.168.1.129    127.0.0.1          UGHS        1       16  lo0
224              192.168.1.129      UCS         0        0  en2
 
ifconfig -a

We would like to know that how you designed the networking..
i mean : connection between routers / switches / server / end systems... everything.. with each IPs..

If possible , pls give a flowchart of the network.. (can be drawn in paint.. itself)

Could you try

route add default gw 192.168.1.0

, restart network and see if that works?

This is an old SVR4 system, circa mid 1990s if I remember correctly.

The output from netstat is interesting. I have formatted it to make it clearer to readers

netstat -rn
Destination        Gateway        Flags Refs Use Interface
default            192.168.1.1    UGS  0 en2
127.0.0.1          127.0.0.1      UH   2 11 lo0
192.168.1          192.168.1.129  UGS  0 0 en2
192.168.1.129      127.0.0.1      UGHS 1 16 lo0
224                192.168.1.129  UCS  0 0 en2

Something is seriously wrong with your configuration. It shows that you have one NIC, i.e. en2, but numerous gateways. You even have the loopback device as a gateway for 192.168.1.129!

In response to linuxadmin...Here is a design of my network.

Internet

connected to Router (Verizon Fios Actiontec) (IP address 192.168.1.1)

connected to a Netgear Switch

windows xp (192.168.1.130)

unix box (192.168.1.129)

(both of these are connected to the switch, which is connected to the router.

Hope this helps. I know it is not a router problem as I had it up and running before the unix pc was rebooted.

This is the route table setup by the system when setting up the network using the built in TCPCONFIG program. I tried deleting the route 192.168.1.129 127.0.0.1, but when I do that I can not ping my unix ip. I have rebooted the router, switch and restarted the network to no avail.

I don't know if this helps, but my router acts as a dns server.

On the unix box I do have it pointing to 192.168.1.1, which is the ip address of the router. However everytime I try to ping the router it hangs. I am assuming this is why I can not ping any other traffic on my network as my unix box can not access the dns server.

Also below I have posted my sdf file that shows how the network is set up on the unix pc. Again, thanks for all the help.
