on a 2000121210 build of mozilla for linuxppc. It appears that if I change the ip of my nameserver in /etc/resolv.conf mozilla needs to be restarted for the changes to take affect. Netscape 4.75 doesn't exibit this behaiviour if /etc/resolv.conf is change Netscape will start looking at the new name server.

dns bug

This is quite strange, since on Linux, mozilla just calls gethostbyname from libc. Can you give anymore details... are there any error messages that appear on the console? thx!

Darin: See bug 40083 marked resolved invalid, but seem to be a dupe of this one.

...interesting... i wonder if it is some sort of wacky side effect of using pthreads? what version of libc are you using? and with which kernel? thx!

on my redhat 7.0 linux box, changes to /etc/resolv.conf only take effect when a process is started. therefore, there doesn't seem to be much we can do to avoid this problem short of spawning a DNS helper process a la NN4.

DUPLICATE SUMMARY: 61434 - using wvdial 1.41, /etc/resolv.conf changes on dialup. 78999 - ppp connect using rh ppp under redhat 7.0 FreeBSD with a PPTP (pptpclient) VPN 82468 - not a DUPE.

an interesting note. under redhat 7.2 (glibc-2.2.4), toggling the offline/online button causes mozilla to re-read /etc/resolv.conf. i'm not sure how this is working.... and, i don't believe it ever worked before.

I have been relying on the Offline/Online toggle for news server access for some time now. If I go offline, then online again in the same session, my news server cannot be found. Toggling 'Work offline'/'Work online' brought it back. Recently (within the last week or two) this has ceased to work, and I am back to shutting Mozilla down and restarting to get to me news server.

Further to my last comment: should I report this as a new bug. It is a gigantic pain in the backside for users like me who are on dialup connections, and who go on and off line frequently. Until a few days ago, I had a workaround with the Work Offline/Work Online toggle. Now I have to blow mozilla away and restart whenever I connect. Is there another workaround. If not, is a reversion to the previous behaviour possible.

cc'ing gordon since he was the proud owner of the patch that "broke" this ;-)

Darin, I'll take this. It may turn into a dup of one of my other bugs anyway. We should be able to at least recover the offline/online toggle functionality, but hopefully we can do better (stat and reread resolv.conf on gethostbyname errors or timeouts, something like that).

Moving Netscape owned 0.9.9 and 1.0 bugs that don't have an nsbeta1, nsbeta1+, topembed, topembed+, Mozilla0.9.9+ or Mozilla1.0+ keyword. Please send any questions or feedback about this to adt@netscape.com. You can search for "Moving bugs not scheduled for a project" to quickly delete this bugmail.

Plussing for 1.0: large win for dialup users, I think we have a patch floating around from the OEone guys, and if not I'll extort one out of someone.

Shouldn't this be a dupe of bug 64857 or vice-versa?

should use res_init(3)?

The situation seems to have improved. If I am on-line when I start mozilla, I seem to be able to go offline and online again without losing my ability to access the net. I don't think this was always the case. However, if I am offline when I start mozilla, I cannot access the net after going online. Work Offline/Work Online does nothing. I have to restart. Some time ago now, I used to be able to gain access by toggling offline/online.

I think this is fixed by 117628's righteous res_ninit patch. I'm (forward) duping, please reopen if it's not really resolved. *** This bug has been marked as a duplicate of 117628 ***

VERIFIED/dupe. not completely fixed, but you can follow the dupe chain to bug 166479.
