Thanks,all of you are very helpful.Lots of thanks.Finally everything is working out of the box.
Before this, in month of may when i first ventured out to explore "what is" linux (i did not had any knowlegde of it),i had installed slackware(i will hate this forever).After installation i had a small problem,(When i installed,i was bit lost),and so went on the slackware forum and asked the question(it was noob question,i feel
to say here).But within hours i had to leave the forum,as i my question was mocked,bashed and then trashed.
Thanks to all of you for keeping patience,all of you were very kind.
Waiting for new problems to come
