Linux Temporary Address - Premature expiry

[Sebastian Wiesinger]

Hello,

I don't know if anyone (except me) tries to use IPv6 temporary
addresses (Privacy Extensions) on Linux.

I tried to use them but noticed that temp_prefered_lft (86400) and
temp_valid_lft (806400) are ignored. My linux changes temporary
addresses every hour and the old address disappears.

That means that every ssh-session and other permanent connections get
disconnected every hour or so which is quite annoying.

Has anybody else experienced this and/or has a fix for me?

Kernel is: 2.6.39-bpo.2-686-pae (2.6.39 from Debian Backport)

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:4dd0:f8dd:0:1dbe:9b1d:5701:82bc/64 scope global temporary dynamic 
       valid_lft 5076sec preferred_lft 1476sec
    inet6 2001:4dd0:f8dd:0:f4e0:b756:3060:50c2/64 scope global temporary deprecated dynamic 
       valid_lft 1485sec preferred_lft 0sec


Regards

Sebastian
