script.bash is your script, which will be crypted to script.secure
script.bash --> script.secure
You can execute script.secure only if you know the password. If you die, your script dies with you.
If you modify the startup line, be careful with the offset calculation of the crypted block (the XX string).
Not difficult to make script editable (an offset-dd piped to a gpg -d piped to a vim - piped to a gpg -c directed to script.new ), but not enough space to do it on a one liner.
Using this command you can track a moment when usb device was attached.
-f file(s) to be monitorized
-n number of last line to be printed on the screen
in this example, the content of two files are displayed
-RR option is used to resume the first appropriate detached screen session
Takes IP from web logs and pipes to iptables, use grep to white list IPs.. use if a particular file is getting requested by many different addresses.
Sure, its already down pipe and you bandwidth may suffer but that isnt the concern. This one liner saved me from all the traffic hitting the server a second time, reconfigure your system so your system will work like blog-post-1.php or the similar so legitimate users can continue working while the botnet kills itself.
The command when added in screenrc enables logging all open windows by using the C-l (control-l key combination) and disable by C-o . The lines need to be added in separate lines .
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
Run inside Command Prompt (cmd.exe) as admin.
Note that you must close explorer.exe first, and even so some files will not be deleted, will say "Access is denied."
To definitely delete them enter with another admin user or from other operating system and access the drive.
Long before tabbed terminals existed, people have been using Gnu screen to open many shells in a single text terminal. Combined with ssh, it gives you the ability to have many open shells with a single remote connection using the above options. If you detach with "Ctrl-a d" or if the ssh session is accidentally terminated, all processes running in your remote shells remain undisturbed, ready for you to reconnect. Other useful screen commands are "Ctrl-a c" (open new shell) and "Ctrl-a a" (alternate between shells). Read this quick reference for more screen commands: http://aperiodic.net/screen/quick_reference
