Mount a Windows share from Ubuntu

How to mount a windows share from ubuntu

# Install smbfs
sudo apt-get install smbfs

# get the UID of the single user, this will be used in editing /etc/fstab
grep $username /etc/passwd | cut -d: -f3
# NOTE $username = the real users login name

# create a file under /home/$username/ named ".smbcredentials" with the following text
username=MyUsername (username could also be username@domain)
password=MyPassword

# protect the .smbcredentials file, because your password is in plain text
sudo chown root .smbcredentials
sudo chmod 600 .smbcredentials

# backup the /etc/fstab
sudo cp /etc/fstab /home/username/backups/

# edit fstab (I used cifs). Make sure its all on 1 line. use the uid you got earlier
//servername/sharename /path/to/mnt cifs credentials=/path/to/.smbcredentials,uid=1000 0 0

# reload fstab
sudo mount -a

Terminal Emulation for Linux

For security and remote administration reasons you can "screen" out of your working terminal and close out of your shell and have access to the working shell remotely and local when you need it. To do this follow the steps below.

Su to root:
$su -
type:
# screen
Now type your commands:
# tshark -i xxxxxxxx
Now hold down the following keys at the same time:
# CTRL + a + d
This detaches the screen and allows you to exit the terminal window.


To access the detached terminal do the following:
From local:
$ su -
# screen -R
This gets you back into the terminal you were working on.

From remote:
ssh to the server
$ su -
#screen -R
You will she your command still running.


Thanks to scm for showing me this.

tshark filter example

Here is a way to capture traffic with tshark and only get what the display filter is showing.

tshark -i 2 -f "port 110" -R "pop.request.parameter conatins "user"" > c:\port110.txt
*********************try "pop.request.command conatins "USER""*************

This will capture all port 110 traffic and filter out the "user" command line and save it to a txt file.

tshark -i 2 -f "port 25" -R "smtp.rsp.parameter contains "Sender"" > c:\port25.txt

This is an example of how to capture traffic on your outbound smtp server.

-i = interface
-f = capture filter
-R= display filter
