From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: Background: a physical interface (i.e.: eth0) with a few virtual interfaces associated to it (i.e.: eth0:0, eth0:1, eth0:2...). When you try to drop just one of the virtual interfaces (i.e.: eth0:3) with "ifconfig eth0:x down", it drops that interface AND all the next interfaces of the same subnet (i.e.: eth0:3, 3th0:4, eth0:5). A weird thing is that previous interfaces remain "up" even if they belong to the same subnet (i.e.: eth0:2). Version-Release number of selected component (if applicable): net-tools-1.60-20E.7 How reproducible: Always Steps to Reproduce: 1.Create a few virtual interfaces (i.e.: "ifconfig eth0:x 192.168.10.x up", etc.). 2.Drop the first of them (i.e.: "ifconfig eth0:0 down") 3. Actual Results: Instead of just dropping the interface mentioned, it drops all the virtual interfaces you created. Expected Results: It should have just dropped one virtual interface, the one you gave in the "ifconfig" command. Additional info: It happens also using "ifdown", but it's normal 'cause it's a script that calls "ifconfig", isn't it?
Fixed in rawhide, net-tools-1.60-55. Will appear in some later RHEL3 update.
Hello. Has this fix (in 1.60-55) already included in net-tools of RHEL3 released??
Can we please get the inputs reposted. I'm missing yesterday comments here due to the raid failure. Thanks
------- Additional Comments From xslaby@fi.muni.cz 2006-06-09 18:14 EST ------- Have you tried to set promote secondaries sysctl variable? I.e.: ifconfig eth0:x 192.168.10.x/24 ... sysctl net.ipv4.conf.eth0.promote_secondaries=1 ifconfig eth0:0 down Addresses on the same subnets are noted as secondaries, when you remove the very first, i.e. primary one, kernel kills others. When you don't want this behaviour, enable promoting of secondaries and kernel will choose the following address (virtual device) and set is as primary. Tip: try to convert to ip(8), it says you they're secondary.
Hi Jiri, Thanks for the provided comments, it is exactly that the issue the customer is encountering. However the 2.6.12 kernel workaround proposing that feature has not yet been included in RHEL3/4. It is possible to use this feature in FC5 as it includes a newer kernel, but as I said, it is not yet possible to promote secondary devices with RHEL. Regards, Jose
