443 port

[Edwin Ruiz_2]

How can i know if my red hat linux is listening for 443 port (https)?

[James A. Donovan]

netstat -a|grep LISTEN|grep 443

If it's listening, you'll see something there...

[Edwin Ruiz_2]

i get that

[root@salato-apl10 conf]# netstat -a|grep LISTEN|grep 443
tcp 0 0 *:4443 *:* LISTEN

i think that this is other port, isnt it?

how can i enable https en linux?

Correct, that's something else.

Using a command like 'netstat -ntlp | grep 4443' will tell you exactally what.

Now, as for getting a 'https' service running, and how easy it is to set up, depends on what Linux distribution you are running.

If you're running a recent RedHat distribution for instance (7.3 or newer I beleive), Apache (httpd) has a 'mod_ssl' package distributed by RH to do it.

If you're compiling your own services, then you'll need the Apache source, the mod_ssl source, and the openssl libraries, and a bit of patience.

If you're running RH (or Debian, i beleive they have packages for https as well), then just go to the appropraite site, and download them.

If you're compiling your own, then start at http://www.modssl.org/ and follow the instructions.

.. Of course I didn't realise that 'mod_ssl' is part of the standard Apache 2 packages/source ..

Going directly to http://httpd.apache.org/docs-2.0/ is a good start.

Hello,

the easiest: Fire up your favorite browser and do a https://localhost/ . If you get a page you have a (secure) Webserver running.

Sidenote: According to my services file port 4443 is "reserved" for Pharos.

Greetings, Martin

Another option is to telnet (if from another station) to port 443. Like in the example
telnet x.x.x.x 443 if you have a black window-then the port is open otherwise you'll get connection failed..

Ok! thanks.. then this configuration depend from Apache but no from linux, isnt it?

[Alexander Chuzhoy]

In most cases the apache (if it's linux) is listening on 443 port.So the answer is yes - The configuration depends on apache.Specifically look in the file
/etc/httpd/conf.d/ssl.conf file.
you have the option to specify different port.

If you have erlier versions of linux then the file to edit would be
/etc/httpd/conf/httpd.conf

ok thanks

Below commands can be used to find whether the port is listening or not.

# nmap | egrep 'https|443'

# lsof -i tcp:443
