Port 25 is not work, How to Enable?

Mousa55 — Thu, 11 Dec 2008 13:28:35 GMT

Hi,

i am try to connect to my server from the Dos by using telnet command and port 25 in this way
#telnet 10.8.1.62 25 but the error message is appeared
Connecting To 10.8.1.62...Could not open connection to the host, on port 25: Connect failed
how to check and enable the port 25.
and this port is working on another server without problem, and i applied the
#netstat -na |grep 25 command and this the output:

4ec52500 stream 0 0 0 4ecec280 0 0
4c2c2500 stream 0 0 0 4bcbf1c0 0 0 /tmp/.AgentSockets/A

Start sendmail daemon:

/sbin/init.d/sendmail start

And to make it permanently - edit the /etc/rc.config.d/mailservs:

export SENDMAIL_SERVER=1

Hi Nejad,

Check for the following files.
1. /etc/services--enable the telnet port, open the port from network side if you are trying to connect it over the network.
2. /var/adm/inetd.sec

Thanks,
Analyst.

Shalom,

Perhaps start the sendmail daemon so some application is running on port 25

/sbin/init.d/sendmail start

For permanent auto start:
edit:
/etc/rc.config.d/mailsvr

Hi nejad,

In my earlier post I gave you wrong information, that was abt telnet instead of smtp port.

I Appologise for that,

SMTP uses port 25, ftp uses 21, telnet uses 23.

Thanks,
Analyst.
