TWDM wrote: > can ping locally on each machine, but can not ping machine to machine Routing? Can you type a few commands on each machine and post the output? "ifconfig" will reveal the address you've given the interface and the subnet mask: # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:00:C0:BA:D0:F2 inet addr:172.23.17.1 Bcast:172.23.17.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:370882 errors:0 dropped:0 overruns:0 frame:0 TX packets:299725 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 Interrupt:11 Base address:0xe000 # Once you have that, "route" will display the routing table: # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.23.17.0 * 255.255.255.0 U 0 0 32 eth0 127.0.0.0 * 255.0.0.0 U 0 0 2 lo # Yours should look something like the one above. If you don't have any routes for eth0, you have to add one. It's something like: % route add 172.23.17.0 netmask 255.255.255.0 eth0 Now, one othe thing: how are the two machines physically cabled? Do you have both machines plugged into a hub, or are they directly cabled? In the later case, you have to use a "crossover" cable that flips the transmit and receive pairs. -- Jerry Callen Mobile: 617-388-3990 Narsil FAX: 617-876-5331 63 Orchard Street email: jcallen at narsil.com Cambridge, MA 02140-1328 PGP public keys available from: http://www.nai.com/products/security/public_keys/lookup_key.asp fingerprints: DH/DSS key ID 0x1806252C: 7669 A4CD 759A 6EB7 AF04 C10D B659 2A4B 1806 252C RSA key ID 0x99F7AAE5: D265 DC9C 13FD 6110 30F5 1874 A206 24B1 - Subcription/unsubscription/info requests: send e-mail with "subscribe", "unsubscribe", or "info" on the first line of the message body to discuss-request at blu.org (Subject line is ignored).
