3. Can't Launch entry

child process " mozilla"

( no such file or directory).


thanks,

pls. help any update.

This is an internal loopback address. It refers to 'localhost', your own computer. Since redhat.com is not on your computer , it's not going to be found.

How do you normally connect to the Internet? Modem? Internal, USB? NIC? Is your NIC configured and active? My first guess would be that you don't have an Internet connection at all, but please confirm this.

is not connected to internet connection. i just connect as cross cable for testing then i will connect as public if everything is oK!

If you know you are not connected to the Internet, then why are you trying to access the Internet, since you know it can't possibly work?

Everything is certainly "OK", insofar as commands attempting to access the Internet correctly report that they cannot do so, but that's probably not what you mean by checking that everything is OK.

In any case, the cause of the problem with nslookup is that it is impossible to gather domain name information about an Internet site such as redhat.com, if you are not connected to the Internet, where that information is stored.

So much for that.

As for Mozilla... two possible problems. First one is: is Mozilla even installed? If not, then naturally it can't be started by whatever process is trying to start it (what process is trying to start it, by the way? In other words, what are you doing when you get the error message that says that the child process Mozilla cannot be started?).

Second possible issue is that (since I assume you're using Redhat-- you might want to update your profile to specify which distribution you're using, that helps us a lot) your version of Mozilla is old, and since the default homepage of Mozilla requires an Internet connection, it's possible that older versions of Mozilla used to crash when they couldn't access the homepage, rather than opening to a blank page with a message. I think I remember that being a problem.

But it's pretty much impossible to say without more information.

As to how to back up your user profile, back up your /home/username/ folder, and that should cover it. You might also want to back up the /etc/ folder to preserve your system configuration files.

Hope this helps.

P.S. Please, in the future, use a more informative title for your posts, such as "Why does nslookup fail?" or "How do I backup my user profile?"

"Please HELP" tells us nothing (everyone posting here needs help, or they wouldn't be here), and most users will ignore a thread so titled.
