Thanks, Jim. Since Slackware is pissing me off by not even recognizing
my wifi card, I'm going back to F13 for a bit.<br>
<br>
Was there some obvious place I could have found out about the need to
restart nscd when moving between networks? (And for the love of all
that's holy, why doesn't the all-singing, all-dancing Network Manager
just do that automatically?) I googled my ass off without achieving
any enlightenment.<br>

or resetting the name services supply. Once nscd is restarted on the
new network, it should float happily between the two known networks
seamlessly.<br>
<br>
if not: summit a bug as it should auto-update from a change in
networkmanager _especially_ from the wireless portion.<br>

already ditched F13 and am installing Slackware on my old Dell D600<br>
laptop, but I wanted to find out if anyone can explain the following<br>
totally psychotic behavior I experienced under F13:<br>
<br>
I set up the laptop's wifi connection on my home network using Network<br>
Manager (gag,spit) and everything worked fine (?!?).<br>
<br>
I went to my SO's house, configured the wifi connection for her network,<br>
and it connected with no problem. I could ping the router and the<br>
upstream gateway by IP or by name. I could ping things out in the world<br>
by name:<br>
<br>
jk@jaklaptop:> ping <a moz-do-not-send="true"
href="http://google.com" target="_blank">google.com</a><br>
<successful ping responses from an actual Google IP><br>
<br>
However, other applications that I tried (FireFox, telnet, ssh) did this<br>
(or in FF's case gave me the equivalent "I can't do that" page):<br>
<br>
jk@jaklaptop:> telnet <a moz-do-not-send="true"
href="http://google.com" target="_blank">google.com</a> 80<br>
Host <a moz-do-not-send="true" href="http://google.com"
target="_blank">google.com</a> not found - Name or service unknown.<br>
<br>
Weirdly, dig and nslookup had no problem resolving <a
moz-do-not-send="true" href="http://google.com" target="_blank">google.com</a>
(or any<br>
other name). But any app that I actually wanted to USE for any practical<br>
purpose complained about name lookup errors, as in the telnet example
above.<br>
<br>
I checked everything in Network Manager and the two networks were<br>
configured identically. I looked at /etc/resolv.conf, /etc/host.conf,<br>
/etc/nsswitch.conf and everything looked totally OK -- the machine was<br>
using the correct router and DNS server for my SO's network. I ran<br>
tcpdump on UDP port 53 while doing a ping and a telnet, and I saw<br>
successful DNS requests for <a moz-do-not-send="true"
href="http://google.com" target="_blank">google.com</a> in both
cases.... but telnet<br>
still complained about "Name or service unknown". I thought maybe it was<br>
something to do with SELinux, so I disabled that, but no joy.<br>
<br>
Then when I got home the laptop connected to my home network and<br>
everything worked fine again.<br>
<br>
I am still at the "WTF?" stage and am not really progressing... hence<br>
the switch to Slackware. Any ideas what might have been happening here?<br>
<br>
Thanks,<br>
<br>
