I just started using Sofia and I can't get dns resolutiomn to work under
windows. Turning debug on I see that sresolv keeps trying to query
my localhost
for dns answers. A quick glance at the code , shows a possible culprit, as
Yeps, this is a known issue:
http://sourceforge.net/tracker/index.php?func=detail&aid=1445560&group_id=143636&atid=756076
sorry for reporting, I should have looked the bug tracker first.
Shortly put, Sofia uses its own async DNS resolver instead the system
resolver, and we need to find out the system DNS server addresses on
startup. On UNIX systems, this information can be read from
/etc/resolv.conf, but and now we need something similar for win32.
I guess the options are:
1) have users create a resolv.conf file for win32 --> define a good
default location instead of /etc/resolv.conf to use on win32
personally I don´t like this approach since you´d have to keep track of
changes and keeping this /etc/hosts in sync with the interfaces dns
servers. I have experienced to much trouble under unix with forgotten
entries on the
/etc/hosts file that superseed dns resolving.
2) use some win32 API functions (windns.h:DnsQueryConfig() maybe?) to
query the server addresses on startup
unfortunately DnsQueryconfig is only available on XP and windows 2000
Professional and up.
3) fetch the information from win32 registry
sounds like the best approach so far. Aparently
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<guid
for specific interface>\NameServer
holds this info. I have to find out if this is valid for all windows versions.
One could open
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces and
for each
interface listed lookup IPAddress and see if it matches the bound interface
address , if so, use the NameServer value.
