wine notes & /etc/resolv.conf

[Grant Williamson]

Hi,
is there a patch anywhere, which will allow wine to reread the 
/etc/resolv.conf file.

i.e.
application lotus notes

a) start notes whilst connected to home network. /etc/resolv.conf gets 
populated by home dhcp server
b) start vpn connection to work /etc/resolv.conf gets populated with 
extra name servers
c) try and connect to work notes, server fails, as it cannot resolve 
named address

If you start notes after the vpn connection is started, then /etc/resolv 
if correctly populated and the problem
does not occur.
Same issue happens when u suspend your machine and start in a different 
location.

Does anyone have a patch or know how to get wine to reread  
/etc/resolv.conf periodically?

Grant.

No problem here with Crossover Office, Notes 6.5.1 and cisco vpn client
4.6-something. But I usually start the VPN tunnel before Notes.

Wine doesn't read the resolv.conf file, at all (ok, I didn't check,
but I'd be very surprised if it did).

Wine uses bog-standard networking support APIs, there's no magic involved
in connecting to the net.

As such the problem is probably that Wine makes use of an API that somehow
doesn't take into account a changed name server configuration.

The best way to find out how Wine does name lookup in case of your
application is to do
strace -f wine ... &>/tmp/wine.log
(hopefully no wrapper script will get in the way)

Then figure out why this API doesn't react to resolv.conf changes,
if this is abnormal behaviour or if Wine should use a different method
to do name lookup.

This is a glibc problem. I'm pretty sure Red Hat fixed this recently as
part of their NetworkManager work. It might be in Fedora Core 3, I'd ask
on fedora-devel.
