I think there are commands get //HTTP:// but I'm
not sure or any other commands?

You could check the process, depending on what version of Solaris use:

For Solaris 7-8.  pgrep -lf httpd (or what the procs name is, you can see all processes with prstat and determine the name)

For other versions.  ps -ef |grep httpd

Hi,

two ways of the top of my head:

1. Check if the process is running

ps -ef | grep http

2. Try to connect to the web server:

e.g. if the web server is running on port 80 on the localhost

telnet localhost 80
get /index.html

If you want to continually check to make sure the web server, is serving pages (and not just running in a hung state), try BigBrother (http://bb4.com/).

It's completely customizable to monitor different services on a system, including web pages.

Is there any version in Windows 95 or 98?

It looks like they support WinNT, but not 95, or 98.  (keep in mind, you don't have to be on a Unix box to check the status of things, that's just where the main program runs from, it exports all it's findings out to a web page)


I've seen some striped down clients for MS Windows, but I can't name them off the top of my head.

If you're looking windows softwhare, why not post over in that area?

Hi nisus
I test it but I receive the following message

<TITLE>Not Found</TITLE><H1>Not Found</H1> The requested object does not exist o
n this server. The link you followed is either outdated, inaccurate, or the serv
er has been instructed not to let you have it.    
What can I do?

if you get a response, then the server is running...if you want actual content, try using / instead index.html...it will default to the default page or provide a directory list if the default page does not exist...or give a permission denied if you don't allow directory browsing.

GET / HTTP/1.0

optionally if you're verifying that a particular virtual site is configured...

GET / HTTP/1.0
Host: www.mydomain.com


where www.mydomain.com is the fqdn of the virtual domain.

i try:

telnet hostname port
GET /index.html HTTP/1.0(carriage return, carriage return)

example:
telnet localhost 80


where the 2 carriage-returns ar important!

if the telnetcommand fails, the server is not running. otherwise you get an error, wich normaly explains the reason. Than the web-server is running!

great, than your webserver is running and produce an internal error shortly explained in your error-message as "misconfiguration". So you must verfiy the exactly reason in the log-files. With Apache, I got  the internal Error when I changed something incorrect of the JAVA-Environment from the Web-Server.

Hi,

When you telnet to port 80 you should 'get' some page.  If your default page is 'index.htm', 'default.asp', 'index.jsp' or whatever, then 'get' that page.

Your default page may be in a subdirectory, in which case you should 'get' the path/default page.

What is a good page to check for?

Regards, Nisus.
