Hello, I have added a static route that sends all traffic for a certain net block over the wlan interface. route add -net xxx.xxx.xxx.0 netmask 255.255.255.0 gw 192.168.1.1 dev wlan0 What is the preferred way in OpenSuse to: a) make this static route permanent? b) make this static route only come up when wlan0 is up? c) delete the static route when wlan0 goes down?

What is the preferred way in OpenSuse to: a) make this static route permanent? Yast/Network/network cards /wlan0/routes

b) make this static route only come up when wlan0 is up? /etc/sysconfig/network/if-up.d custom script

c) delete the static route when wlan0 goes down? /etc/sysconfig/network/if-down.d custom script

TIA, Amedee

Hello,

route add -net xxx.xxx.xxx.0 netmask 255.255.255.0 gw 192.168.1.1 dev wlan0

What is the preferred way in OpenSuse to: a) make this static route permanent? Yast/Network/network cards /wlan0/routes

Thanks. I was looking at the "global" routes config in Yast, didn't realize that each individual interface could have routes too. You see, I'm used to routing on Cisco IOS, so I know the basics, I just need to fing the right place to do what I want.

OK thanks, I can do that. I already considered that but I was hesitant because perhaps Yast could already provide this. But you just told me I was on the right path anyway. -- Amedee -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Yes of course you may recommend that. It's just that most pages on the web still refer to route and ifconfig. But with my Cisco experience, it feels more comfortable to use ip. I wasn't fully aware it even existed, and I certainly didn't know that route&ifconfig are deprecated. -- Amedee -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

One example of deprecation is the addition of several IP adresses to one interface. Here I add 10.42.42.42 for eth0, and as the example shows ifconfig will not show it. So people using ifconfig might never find additional IP addresses added to an interface. blitz:~ # ip addr add 10.42.42.42 dev eth0 blitz:~ # ip addr list eth0 2: eth0: mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:07:e9:83:c5:f1 brd ff:ff:ff:ff:ff:ff inet 10.0.2.200/24 brd 10.0.2.255 scope global eth0 inet 10.42.42.42/32 scope global eth0 inet6 fe80::207:e9ff:fe83:c5f1/64 scope link valid_lft forever preferred_lft forever blitz:~ # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:07:E9:83:C5:F1 inet addr:10.0.2.200 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::207:e9ff:fe83:c5f1/64 Scope:Link UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:55559240 errors:0 dropped:0 overruns:2627 frame:2627 TX packets:11740967 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:267695005 (255.2 Mb) TX bytes:2188450034 (2087.0 Mb) -- Mads Martin Joergensen, http://mmj.dk "Why make things difficult, when it is possible to make them cryptic and totally illogical, with just a little bit more effort?" -- A.

Add a /etc/sysconfig/network/ifroute-wlan0 file. See man 5 routes Lars -- Lars Müller [ˈlaː(r)z ˈmʏlɐ] Samba Team SUSE Linux, Maxfeldstraße 5, 90409 Nürnberg, Germany
