From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.8) Gecko/20061107 Fedora/1.5.0.8-1.fc6 Firefox/1.5.0.8 Description of problem: After a fresh install of FC6, if you edit your hostname using system-config-network, it will remove the "127.0.0.1 localhost..." line from the "hosts" file and, therefor, will cause programs such as mc and vmwareserver really slow to load. If you manually insert back that line to hosts file, everything works fine again. Version-Release number of selected component (if applicable): system-config-network-1.3.95-1 How reproducible: Always Steps to Reproduce: 1. Install FC6 2. Leave network settings as anaconda's default (ip by dhcp active, auto dns etc.) 3. network and everything else works ok 4. /etc/hosts file seems ok (additional information 1) 5. Open system-config-network and change the hostname under the tab "DNS" Actual Results: Programs like mc took minutes do load. You are leaded to think the program has crashed. my /etc/hosts file no longer had the line "127.0.0.1 .." (additional information 2) 8. Manually edit hosts file and add "127.0.0.1 localhost.localdomain localhost" plus your new hosname assigned when using system-config-network 9. Everything works fine again Expected Results: I'm not sure, but I think the line "127.0.0.1 ..." should've stayed in hosts file, including the new assigned hostname entered in system-config-network Additional info: 1. Original hosts file (after a fresh install of FC6): # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost ------------------------------------------------------ 2. hots file after changing hostname in DNS tab using system-config-network tool: # Do not remove the following line, or various programs # that require network functionality will fail. ::1 localhost.localdomain localhost
correct... b/c ananconda set this "::1 localhost" line..
will fix s-c-network
This issue was first noticed in bug #211800 (and noted there that when anaconda is fixed to write out the two lines properly, as 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 then s-c-network does leave both lines alone).
(In reply to comment #2) > will fix s-c-network Great! Thanks, Cheers.
Hello, any news about this bug?
[I just added this to 211800] My symptom is described in 216919. This may well be an Anaconda bug but no update can fix an Anaconda bug (as I understand it). To get a fix in out there for FC6, s-c-n needs to have a work-around for the Anaconda bug.
This bug is still present in FC7 test 2 (live cd). After saving from the system-config-network, there is only this line left in /etc/hosts: ::1 localhost.localdomain localhost When removing the 127.0.0.1 line, the BankID login Java applet used in many Norwegian banks fails when you try to log in - it took a couple of days to figure out what was wrong. So it would be very nice if this could be fixed for FC7.
It's stuff like this that frightens new users away from FC. The user installs, everything seems normal, but for no reason, programs doens't load... The new user won't even have the chance to test his recently installed FC. Only advanced/experienced users would check into the hosts file to see if everything is alright. Sure it would be very nice if it was fixed. Cheers, guys!
