[opensuse] Adding multiple IP addresses to existing NIC
Hi All, Thanks for any pointers. On Suse 9.3(CONSOLE only, no GUI), what are the steps needed to add multiple IP addresses to the NIC ? Previously, while using Redhat (not Fedora), we used to a) make a copy of ./etc/sysconfig/network-scripts/ifcfg-eth0 b) rename the copy to ./sysconfig/network-scripts/ifcfg-eth01 c) edit the contents of the new file and d) reboot and lo and behold, we had multiple IP addresses for the NIC. What are the equivalent steps for Suse 9.3 ? Thank you so much, BR, ~A

This is easier in SUSE. From /etc/sysconfig/network/ifcfg.template: ## Multiple addresses ## You can extend the variable name 'IPADDR' by any string you like (IPADDR_1, ## IPADDR_FOO, IPADDRxxx, ...) and use these variables for your IP addresses. ## If you need some additional parameters for these addresses, then just add ## the same extension to these variable names. ## IPADDR_AAA=1.2.3.4 ## NETMASK_AAA=255.0.0.0 ## BROADCAST_AAA=1.2.3.55 ## IPADDR_BBB=10.10.2.3/16 ## LABEL_BBB=BBB ## an so on ... ## ## You do not need to set a label for any address. But then you should not use ## ifconfig any longer; go and use ip. If you want to use ifconfig then omit the ## label for your main address and set a label for every additional address. So you simply need to edit the /etc/sysconfig/network/ifcfg-eth-id-<mac> file and add the addresses. I usually specify only IPADDR for each additional entry in cidr format like so: IPADDR_FOO='10.1.1.1/24' IPADDR_BAR='192.168.1.1/24' Once you save the file, there's no need for a reboot. You can do one of the following: ifdown <devicename> ; ifup <devicename> or rcnetwork restart Hope that helps, -- James Oakley jfunk@funktronics.ca --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Hi james , thanks fro this help i also need the same thing , but i may have some more need if u can help a great appreciation . like i am using suse_10.1 iam having one eth0 and 2 different internet connections 1.Office 2.Home both are static ip now i write a shell script when i logged in to home or office so run the script and it make the Network entries accordingly . but every time i need to overwrite my "resolv.conf" and gateway entries which are very different for Home and Office . Example : Office : IP: 210.X.X.X gateway: 210.X.X.254 Primary NameServer : 220.X.3.X Secondary NameServer:220.X.4.X Home : IP:61.X.X.X gateway:61.X.X.254 PS:110.X.X.X SS:110.220.X.X So how can make this both entrie in suse and ever time i need not require to run a script like in REdhat we have a choice of making network profile and and once boot u can choose a network profile and corresponding entries are loaded auto. Do we have like for suse ???? let me know .. thanks for co-operation. -- ======================================================= With Best Regards Mr.Shailesh Bhutada(CTO) Web:www.comptrixsys.com Email::kernel.2k5@gmail.com :shailesh@cspl.com :shailesh_oss@redhat.com ========================================================= This Message is sent Via Qmail-smtpd@comptrixsys.com Server Suse 10.1 Linux Using Opera's e-mail client or Mozilla ThunderBird Mail Client. ========================================================= James Oakley wrote:

In YaST, go to System -> Profile Manager, which will let you setup SCPM, which will do exactly what you want. You will even get a tray icon that will let you switch easily. SCPM is particularly cool because any settings you change are saved to the profile any time you switch a profile. Even if you manually edit your /etc/resolv.conf or /etc/sysconfig/network/ifcfg-eth-id-* files, SCPM remembers the changes. It does the same for any daemons you run, including whether they are running or not.
