Sorry I have posted this problem yesterday and I thought I solved it but apparently I did not.
I have Debian 3.0 on Ultra 10 SPARC machine. It has two network interfaces eth0 on 192.168.1.0 with IP 192.168.1.20 eth1 on 10.5.5.0 with IP 10.5.5.20 The problem that I have is that machines on the 10.5.5.x subnet cannot ping the IP 192.168.1.20 and machines on 192.168.1.x subnet cannot ping the IP 10.5.5.20.This is only unique to this box. Other dual homed machines running Windows or Mandrake are accessible from both sides. The file /etc/network/interfaces looks like the following: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.20 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 auto eth1 iface eth1 inet static address 10.5.5.20 netmask 255.255.255.0 network 10.5.5.0 broadcast 10.5.5.255 The output of route -n command looks like the following: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.5.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 The output of ifconfig looks like the following: eth0 Link encap:Ethernet HWaddr 08:00:20:FD:C7:09 inet addr:192.168.1.20 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4576 errors:0 dropped:0 overruns:0 frame:0 TX packets:1625 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:363616 (355.0 KiB) TX bytes:286891 (280.1 KiB) Interrupt:32 Base address:0x8800 eth1 Link encap:Ethernet HWaddr 00:48:54:62:B0:73 inet addr:10.5.5.20 Bcast:10.5.5.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3160 errors:0 dropped:0 overruns:0 frame:0 TX packets:304 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:329148 (321.4 KiB) TX bytes:35909 (35.0 KiB) Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:38 errors:0 dropped:0 overruns:0 frame:0 TX packets:38 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3650 (3.5 KiB) TX bytes:3650 (3.5 KiB) Any help is much appreciated Thank you Mostafa -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
