Okay, what is the output of: # /sbin/ifconfig eth0:0 eth0:0 Link encap:Ethernet HWaddr 00:50:04:44:1F:C3 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:10 Base address:0xe800 This should confirm the kernel has been configured, complied and booted correctly. I am running from a 2.2.x box with these tools: # /sbin/ifconfig -V net-tools 1.52 ifconfig 1.39 (1999-03-18) However I think IP aliasing has been a feature for more than a couple of years, heh. I think I was wrong to think they needed to be 'up'ed, they appear to track the master devices 'eth0' flags. However they are not visible in a 'ifconfig -a' output until the IP address is set. # /sbin/ifconfig eth0:0 eth0:0 Link encap:Ethernet HWaddr 00:50:04:44:1F:C3 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:10 Base address:0xe800 # /sbin/ifconfig eth0:0 10.1.1.1 eth0:0 Link encap:Ethernet HWaddr 00:50:04:44:1F:C3 inet addr:10.1.1.1 Bcast:10.255.255.255 Mask:255.0.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:10 Base address:0xe800 Charrua wrote: > > Hi, I tested "ifconfig eth0:0 up 200.61.94.98" and this didn't work. > > My kernel is 2.2.15 and the result of ifconfig -a' and 'ifconfig -V > is: > > Thanks, Andres > > ifconfig -V > > net-tools 1.46 > ifconfig 1.35 (1998-08-29) > > ifconfig -a > > lo Link encap:Local Loopback > inet addr:127.0.0.1 Mask:255.0.0.0 > UP LOOPBACK RUNNING MTU:3924 Metric:1 > RX packets:0 errors:0 dropped:0 overruns:0 frame:0 > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 > > eth0 Link encap:Ethernet HWaddr 00:00:E8:13:7B:C4 > inet addr:200.40.10.35 Bcast:200.40.10.63 > Mask:255.255.255.224 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:6772 errors:0 dropped:0 overruns:0 frame:0 > TX packets:3907 errors:0 dropped:0 overruns:0 carrier:0 > collisions:8 > Interrupt:5 Base address:0x220 > > eth1 Link encap:Ethernet HWaddr 00:00:E8:13:91:70 > inet addr:192.168.1.1 Bcast:192.168.1.255 > Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:5538 errors:0 dropped:0 overruns:0 frame:0 > TX packets:5634 errors:0 dropped:0 overruns:0 carrier:0 > collisions:1 > Interrupt:10 Base address:0x300 -- Darryl Miles Webtraffik Netbauds Ltd www.netbauds.net - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
