Loosing IP configuration after reboot
 

Hi everybody

I am new to this forum. I have a problem with one of my production servers which is running under Linux Suse 9.
The problem is that after I configure the NIC (with yast tool) all is ok. the ifconfig returns the correct values and I can ping to remote IP addresses, however, after rebooting, I loose the whole configuration and I should re-configure my NIC once for each reboot.

Is there a way to make this configuration permanently ?

Thanks in advance for your help

Well, once you've setup your configuration using yast, do this in a terminal:

[rylan@StefanLinux ~]$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.254.255.0 * 255.255.255.0 U 0 0 0 eth0
default 192.254.255.100 0.0.0.0 UG 0 0 0 eth0
[rylan@StefanLinux ~]$

Make a note of the value in the "default" line (192.254.255.100) - this is your gateway.

To setup the above manually you need to do:

/sbin/ifconfig eth0 192.254.255.20 netmask 255.255.255.0 broadcast 192.254.255.255 up

route add default gw 192.254.255.100 eth0

Of course, the 192.254.255.20 is my IP address, and that you cannot get off the route command. Instead, call ifconfig to get your IP address assigned with yast:

[rylan@StefanLinux ~]$ /sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:50:22:A4:47:61
inet addr:192.254.255.20 Bcast:192.254.255.255 Mask:255.255.255.0

[rylan@StefanLinux ~]$

Thus, you then just need to substitute your correct address, and place the following into your /etc/rc.local file. This will then get run each time the PC is started up:

with, of course, your yast-configured addresses substituted.
