SSH port change - possible??

Hello,


Due to recent attacks, I decided to change my ssh port. How can I do that as well as diabling the default 22 port'

I changed port in my /etc/ssh/sshd_config , sshd_conf , ssh_conf files but still I am able to connect with port 22

Is something wrong I am doing?

Please help.

Thanks in advance.....

 

have you restarted Apache?

 

Yes. I am restarting again. WIll post here in a min.

 

No.

Still I am able to connect by port 22

Is this possible to disable port 22?

 

That's strange. I had to do this on my server once. This is the file that needed to be modified.

/etc/ssh/sshd.conf

you then need to restart SSH by typing this in your terminal

/etc/init.d/sshd restart

I'm not sure what version of linux you're running though. I have redhat linux on my server.

 

nano /etc/xinetd.d/sshd

service ssh
{
        disable = no
        socket_type             = stream
        type                    = UNLISTED
        port                    = 22
        protocol                = tcp
        wait                    = no
        user                    = root
        server                  = /usr/sbin/sshd
        server_args             = -i
}

Code (markup):

Change "port = 22" for the new port and restart.

with this command or control panel

service sshd reload

Code (markup):

 

I dont have that file....I am usng CentOS

 

u restarted ur server ??

 

How do I do that...I havent edited as I dont have that file so, whats the need to restart??

 

u edited this file rite /etc/ssh/sshd.conf

after that did u restart the server ???

if ur having bruce force attacks on your ssh server install this http://www.csc.liv.ac.uk/~greg/sshdfilter/ it will ban the attacks

 

what port did you change it to?

 

also, can you post the part of your /etc/ssh/sshd.conf file that has the information you edited?

 

Hello guys


Just I noticed I solved the problem.

I was needed to remove only a # freom the file....I am so stupid

Thanks to all who helped

 

lol u forgot to mention the imp part huh

 

that's why I was asking that you post the text. Glad you figured it out.

 

FOr others who want to change the ssh port:

Open your /etc/sshd_config file

You'll find a line saying

# Port 22

Code (markup):

Replace it with

Port xxxxx

Code (markup):

Notice the "#" which is not present in the second code...

Now restart the server. Also, make sure that the port doesnt conflicta with any other port used by your system.

Post here if you hae any other problem

 

I came across this tutorial for CentOS also that people might find useful.

nano -w /etc/ssh/sshd_config

after the edit dont forget to restart

/etc/init.d/sshd restart

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
