gem & wget not able to resolve

Hi all,

I am facing a weird problem. gem & wget are not able to resolve addresses. while, apt, ping, web browsers work fine.


sudo gem update --system
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)

$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.1.1


'export HTTP_PROXY' does not return anything.

I think if the dns resolving for gem & wget gets solved, then gem can use the sources to do automatic installations of gems.

I tried changing nameserver to 8.8.8.8 but after reboot, it reverts back to above.

Please help me resolve this. I tried to manually install gems. But, it is insane task to keep searching & downloading each gem dependency and installing it.
