here is the current output of ifconfig Code: eth1 Link encap:Ethernet HWaddr 00:C8:09:C3:0F:91 inet addr:10.15.35.79 Bcast:10.15.35.95 Mask:255.255.255.224 inet6 addr: fe70::2d5:9ff:fec3:f71/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:48825240 errors:0 dropped:0 overruns:0 frame:0 TX packets:29007556 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1717150188 (1.5 GiB) TX bytes:3147960533 (2.9 GiB) Interrupt:11 Base address:0xd400 eth1:3 Link encap:Ethernet HWaddr 00:C8:09:C3:0F:91 inet addr:10.15.35.83 Bcast:10.15.35.95 Mask:255.255.255.224 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:11 Base address:0xd400 eth1:5 Link encap:Ethernet HWaddr 00:C8:09:C3:0F:91 inet addr:192.168.1.51 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:11 Base address:0xd400 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:20842 errors:0 dropped:0 overruns:0 frame:0 TX packets:20842 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18520113 (17.6 MiB) TX bytes:18520113 (17.6 MiB) How can I use ifconfig to "clone" the settings of eth1:5 to eth1:7 with an ip address of 192.168.1.5 ? My real goal is to have this pc poll our main RedHat server's ip address and if no response (ie: RH is down), then this pc should take over the ip address of the RH and provide the email and internal DNS services.
i can give u half a tip for the DNS on the server thats gives out the DHCP just add second DNS IP to option domain-name-servers line here mine option domain-name-servers 192.168.1.10, 192.168.1254; .10 = my inhouse DNS serer .254 = router - DNS
