[Bug 717774] New: More support for IPv6 parameters in YaST
https://bugzilla.novell.com/show_bug.cgi?id=717774 https://bugzilla.novell.com/show_bug.cgi?id=717774#c0 Summary: More support for IPv6 parameters in YaST Classification: openSUSE Product: openSUSE 12.1 Version: Milestone 5 Platform: Other OS/Version: SuSE Other Status: NEW Severity: Enhancement Priority: P5 - None Component: YaST2 AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: f.de.kruijf@gmail.com QAContact: jsrain@suse.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2 The standard in openSUSE 12.1 M5 on privacy using IPv6 is now that each so many minutes a new IPv6 source address will be generated and that stateless autoconfiguration always will be used. A report has been seen that long standing connections suffer from these settings. This requires more control on these settings, which should be available in YaST, Network Devices, probably in Global Options or more advanced both in Global Options and individual device settings. This is about YaST generating /etc/sysconfig/network/ifsysctl and /etc/sysconfig/network/ifsysctl-<interface_name> defining the parameters use_tempaddr and the one that controls the use of stateless autoconfiguration. Obviously disabling stateless autoconfiguration should imply the use of a fixed address or the use of DHCP6.

These parameters contain by default respectively the values 86400 (1 day) and 604800 (1 week). But I am not quite sure which value is the one that really controls the lifetime of the temporary IPv6 address. -- 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.

A report has been seen that long standing connections suffer from these settings.
Can you be more specific, link to the report? Do we really want to expose the parameters? If it is indeed a problem, can we rather change the default than burden the admin with another configuration decision? -- 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 default which is set in openSUSE is 1 day; I found that recently. I don't know what happens around the time the address is changed. Is it kept around for a while? But still the default is now, very recently changed, to have privacy enabled, which may cause problems. I would suggest to have the privacy set on laptops and not on desktops and servers. Maybe that parameter use_tempaddr should be set to 1 on desktops and 2 on laptops. Burden the admin is quite relative, if he/she does not understand it, the default should be sufficient. With some explanation the admin should be able to make a proper choice. I found configuring the mail server with YaST very complicated, compared to configuring the network even with this complication is still, IMHO, easy. -- 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.
