I have got red hat5 installed on my pc,but not able to run perl or php programs on it. only html display can be obtained,but perl and php programs are not running on firefox browser.when executed,web browser page with server not found msg is displayed.

perl is installed on your box anyway. Server not found? Did you install a webserver and is it running?

If you are getting error messages it is often useful if you post the full wording of the error messages you're seeing. That is, do not write a description of the error message in your own words, use copy/paste.

Keep in mind that there is a Red Hat 5 (very old) and a RHEL5(Red Hat Enterprise Linux, current). These are two totally different products.

IF you are really running Red Hat 5, please stop and switch to a more current (supported) version.

IF you are running RHEL5, then contact RH and ask them to see what is going on. That is what the license fee is for(support).

Actually, RHEL 6 was recently released, so 5 isn't current any more.

RHEL 5 isn't current as in being the newest version of RHEL. It is however current as in being something which Red Hat are currently providing support for.

NO.. red hat server is not installed.. actually I'm not able use internet.Its not getting connected.I have a broadband connection wit UT300R2U modem..

That response doesn't contain any information that can be used to assist you. It actually makes it even less clear what your problem is since you are now claiming that Red Hat isn't installed after you originally stated that you are using Red Hat.

A good starting point might be for you to post the content of the file /etc/issue. This will clarify what version of Linux you are actually using.

It might also be helpful if you post the output of these commands

Internet connectivity problems do not appear to have any relevance to your original post. Stick to one issue per thread.

Redhat9 is what we use in our college to work.. but my installer didnt have that version,so i got redhat5 installed..i think we can execute perl and php programs on it...

OK... Like I said, post the contents of the file /etc/issue so we can see what version of Red Hat you are actually using. As lazlow said, there's two possibly versions you could be refering to as 'Red Hat 5'.

Red Hat 9 is very, very old. Old enough that you should not be using it.

If you're referring to Red Hat 5 as opposed to RHEL5, you're using a distribution that was current when I started playing with linux, back around 1996/7 IIRC. This would bear absolutely no resemblance to current distros... no installable kernel modules, Apache 1, no Gnome or KDE. Doubtful that you'd have PHP available either.
If you really don't have any way to get a current distro, PM me your postal address and I'll mail you a DVD.

As above, type these cmds and post the output

cat /etc/issue

cat /etc/*release*

uname -a
