SSH, SFTP, and SCP on non-standard ports

One common suggestion for securing a secure shell connection on Linux is to change the port that ssh runs on.  But how exactly do you connect to a server on one of these non-standard ports?

Naturally, the syntax is different for each so here goes:

ssh

ssh -p 33432 user@server.com

Yes, ssh uses a lower case p command line argument. Just wait until we get to scp.

sftp

sftp -o "Port 33432" user@server.com

Of course sftp uses a plain English option parameter of “Port XXXX”

scp

scp -P 33432 /home/user/file.txt user@server.com:/home/user

And naturally scp uses a capital P

Gotta love consistency!

Mount a Windows Share in Linux

So you want to access a Windows UNC share in Linux?  No problem if you know the magic commands and have root access.  This can be a great alternative to running cygwin if you are able to access a linux box (directly or via a virtual machine).

First, start by creating your mount point…

sudo mkdir /mnt/share1

Then, actually mount your UNC share to the mount point…

sudo mount -t cifs "//server/share1" /mnt/share -o username=my,password=secret

This would make \\server\share1 available to you on the Linux box as /mnt/share. Note the use of the options parameter (-o) to specify username and password.

Start ColdFusion8 on Ubuntu Server Start

Ok, so this is not the most bleeding edge post, but hopefully useful if you need it.  Here’s what you need to do if you need to get ColdFusion8 to start on server reboot (since it doesn’t appear to install itself as a service) using Ubuntu server.

First, create a service script and make sure it’s executable like so…

sudo touch /etc/init.d/coldfusion
sudo chmod 755 /etc/init.d/coldfusion

Next, you need to actually put something in the script…

sudo nano /etc/init.d/coldfusion

Here’s what to put in the file…

#! /bin/sh

### BEGIN INIT INFO
# Short-Description: ColdFusion8 service
### END INIT INFO

file=/opt/coldfusion8/bin/coldfusion

case "$1" in
stop)
$file stop
;;
status)
$file status
;;
restart)
$file restart
;;
*)
$file start
;;
esac

exit 0

Finally, you need to tell Ubuntu to use your service and make it available

sudo update-rc.d coldfusion defaults
