Ive done some searching in these forums for DNS issues and Im stuck trying to find a solution so hopefully someone can help.
I am running Redhat 9 from a workstation on a lan behind an external router/firewall. I am able to browse the internet fine and all of my applications can resolve host names just fine.
I am having a problem with just -one- application. IglooFTP ftp client, where it saves "cannot resolve host name". I have checked for common issues that I would imagine would relate to "any" net-capable application, such as making sure my ISP's name servers are in the /etc/resolv.conf file.
Here are the bizarre issues..
- I have DNS server installed (I am not using it though) - and when I manually add a host name/ip using the DNS server, IglooFTP -will- resolve the host name. (This should not be needed though - as I want it ti query the ISP's name servers like all the other apps)
- When I tried IglooFTP on another machine on the lan, it works properly - resolving host names without a problem.
I have tried to troubleshoot by checking for differences in configuration, etc.. and there are no differences whatsoever.
I have also tried re-installing the package and it still reports the problem..
Any suggestions? Im not sure what an application does to resolve a host name - but it would seem it is only checking my local DNS info? And not checking the ISP's name server???
