How to get FQDN using NSIS Script

[nsisadmin]

Currently we are using "Internet::GetLocalHostIP ${ip_addr}" to get the local host IP and using the IP for registering the application.

But to handle hosts with multiple NIC card, we are planing to use the FQDN(Fully Qualified Domain Name) instead of the ip address.

Is there any way to get the FQDN of the localhost using NSI script? Any other known workaround?

may be we can get the fqdn by appending domain name after hostname. how to get the hostname? any available plugin?

I believe you want to use the getnameinfo win32 api call for this.

Thanks Zinthose. The wiki was of great help.

I need to use few of the IpConfig plugin APIs(like GetHostName, GetPrimaryDNSSuffix, GetAllNetworkAdaptersIDs, GetEnabledNetworkAdaptersIDs, GetNetworkAdapterIPAddresses etc.). But looks like IpConfig plugin is not working properly(I am trying with windows XP).

Please help.

Looks like you already found the IPConfig Plugin Forum Topic (http://forums.winamp.com/showthread.php?s=&threadid=307666)

Listen To MSG he has the answer ;-)

The dll should be in NSIS\Plugins, not $INSTDIR\plugin.

Just to clarify that is the NSIS\Plugins dir were you have NSIS installed.
