"No route to host" on RH 8.0 + W2K LAN

szatki · 02-19-2004, 09:45 AM

I'm trying to connect to a windows 2000 box from RH8.0 on a LAN behind a firewall. I don't know much about networking, but I'm getting the "no route to host" error. Here's my routing table:

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
134.174.151.0   *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo
default         134.174.151.1   0.0.0.0         UG    0      0        0 eth0

I'm trying to connect to 134.174.151.138

Thanks!

You've configured a network address (*.0) on an interface. That's likely to arse up your setup right now.

The network you're connected to, has a configurable IP range from 134.174.151.1 to 134.174.151.254

*.1 is the router (apparently)

so you need to find a free IP address between *.2 and *.254

Unless your netmask of 255.255.255.0 is incorrect and you *do* have a LAN larger than 254 usable IP addresses.

Do you mean that I need to define my own IP address in the routing table? I am using DHCP -- does that change things? (Sorry, should have mentioned that before...)

Your DHCP server has assigned you that IP address???
...

Can you ping the gateway address....?

Yes, I can ping 134.171.154.1

Whoops, yes I can ping 134.174.151.1 (!)

D'Oh! I misread your routing table. Of course that's the network address, it's supposed to list that.

Your routing table looks ok. Do you know the address of the DHCP server? Can you ping that?

Problem solved: the IP address that I was given for the W2K box was incorrect -- argh! Sorry for the trouble!! And thanks for your efforts!
