[Bug 352841] New: impossible to remove first alias of a interface when more aliases than one configured
https://bugzilla.novell.com/show_bug.cgi?id=352841 Summary: impossible to remove first alias of a interface when more aliases than one configured Product: openSUSE 10.3 Version: Final Platform: 64bit OS/Version: SLES 10 Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: reitenbach@rapideye.de QAContact: qa@suse.de Found By: Customer when I configure multiple aliases on a network interface, and then later want to remove the first created alias, all aliases will be removed. When I remove any other alias, then only this alias I want to remove will be removed, without touching the other aliases. example: creating the aliases: ifconfig eth0 10.10.10.10 netmask 255.255.255.0 up ifconfig eth0:2 10.10.0.18 netmask 255.255.255.0 up ifconfig eth0:3 10.10.0.19 netmask 255.255.255.0 up ifconfig eth0:1 10.10.0.20 netmask 255.255.255.0 up ifconfig eth0:0 10.10.0.17 netmask 255.255.255.0 up ifconfig eth0:4 10.10.0.16 netmask 255.255.255.0 up when I then want to remove alias e.g. eth0:1, without affecting the other aliases, then there is no problem, when issuing command: ifconfig eth0:1 down then only this alias is gone. But when I want to remove the first created alias this way: ifconfig eth0:2 down then all aliases are gone. This is the same in opensuse 10.1, 10.2, 10.3 and SLESsp1. As this behavior is not documented in the ifconfig man page, for me this seems to be a bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Maybe the manual page of the ifconfig command should receive an update, e.g. noting this behavior regarding aliases in the BUGS section, adding ip(8) to the see also section and making a note that ifconfig is deprecated. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The stop action will show error messages, as the first ip addr del removes all aliases. the commented out fields show it working correctly when no netmask is specified, but then strange netmasks/broadcasts are generated. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In my test where I concluded it works with the ip utility I did not had specified a correct netmask. Without specifying a netmask when creating the alias, then it is possible to shutdown the first ip alias without affecting otherwise when the alias is created with a netmask then when shutting down the first alias, all the other aliases will disapear too.

Removing secondary addresses one-by-one is fine. The example in the initial description doesn't reproduce for me, but the script does. It seems to occur when a _new_ subnet is added via an alias (which gets added as a primary/global address); then all further addresses from that subnet will be secondary, and removing the primary stops these. The first example shouldn't show this behaviour, as eth0 itself is never brought down. The script though does add an entirely new network range. Normally, aliases are from the same subnet as the primary address, and then do not show this behaviour. No work-around exists, I tried various ip flags. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
