IMPORTANT!

Snipt is going open source. We've toyed with this idea for quite a while, and have finally decided it's the right way to move forward.

A few things:
  • The entire Snipt source code will be released on GitHub under the 3-clause BSD License on Friday, September 10th.
  • While we'd like to think we're perfect, we realize we're only human. By open sourcing the software that runs this website, certain bugs or security flaws may be discovered that could compromise the privacy of your snipts.
  • Only the Lion Burger team will be able to push commits to the Snipt.net site. Contributors should send a pull request to add new features or submit patches.
  • By using this site, you agree not to be too angry or take any legal action against Lion Burger should this whole thing go up in flames some day.
  • Follow us on Twitter for updates.

  • ∞ ssh disable timeout firewall 
    http://madphilosopher.ca/2005/07/an-ssh-keep-alive-tip/

It’s worth noting that many SSH timeouts come from firewalls and no amount of tinkering with timeout settings (other than on the firewall) will fix it. The only way in these cases is to simulate traffic (which is what the client’s keepalive settings should do, but don’t always in my experience).

I find this works very well (although possibly it’s overkill being in perl):

perl -e 'sleep 59 && print STDERR "\x00" while 1' &

Run it as soon as you SSH in, and remember the pid so you can kill it before you leave. It squirts a null every 59 seconds. If you change the \x00 for a printable character you will see it appear on your terminal but it still won’t impact what you are doing.

–
# Adam Reed Says:
May 6th, 2007 at 0303 UTC

Bruce:

You can automate this by putting the following in your .kshrc (or its equivalent for your shell in its rc file, or put it in .profile (or .login)):

case $- in i*s*)
perl -e 'sleep 59 && print STDERR "\x00" while 1' &
trap "kill ${!}" 0
;;
esac


# =======================================================================================
Remember that

ServerAliveInterval

is limited by

ServerAliveCountMax

and that ServerAliveCountMax is set to 3 by default!

That is, if you set ServerAliveInterval to 60 and ServerAliveCountMax is left to default value (3), after the client has sent 3 keep alive packets it will disconnect. That makes 60 x 3 = 180 seconds.

So if you want more time away, you set ServerAliveInterval to 60 and ServerAliveCountMax to the numer you want (for example: 100). The client will send one keep alive packet every 0 seconds for 100 times or, if you prefer, 100 keep alive packets, one every 60 seconds. :D

You set this up in your $HOME/.ssh/config file.

Most of these options are explained in man ssh_config.


DiskStation> grep ClientAliveInterval /etc/ssh/sshd_config
ClientAliveInterval 100

  • ∞ Deploying a CakePHP App on a Media Temple (dv) 3.5 Server using a Subdomain 
    USE:
	Deploy a CakePHP App to mysubdomain.example.com


NOTE:
	Looking to deploy on a regular domain like example.com?
	See: http://snipt.net/chrisyour/deploying-a-cakephp-app-on-a-media-temple-dv-35-server/
	
	
STEP 1: SET UP DOCUMENT ROOT VIA SSH

	# TERMINAL: login to SSH as root (and enter your password)
	ssh root@example.com

	# TERMINAL: change directory to the conf folder (example.com)
	cd /var/www/hosts/example.com/subdomains/mysubdomain/conf

	vi vhost.conf

	# VIM: Press the 'i' key to begin inserting content

	# VIM: Type in the document root into Vim
	DocumentRoot "/var/www/vhosts/example.com/subdomains/mysubdomain/httpdocs/app/webroot"

	# VIM: Press 'esc' key once you're finished inserting content

	# VIM: Type ':wq' then press 'return' key to write to the vhost.conf file and quit Vim


STEP 2: RECONFIGURE VHOST

	# Terminal: 
	/usr/local/psa/admin/sbin/websrvmng --reconfigure-vhost --vhost-name=mysubdomain.example.com

	# Terminal: Restart Apache
	service httpd graceful


STEP 3: MIGRATE YOUR DEVELOPMENT DATABASE TO YOUR PRODUCTION ENVIRONMENT

	# Dump your local database into a .sql file on your computer

	# Login to Plesk and use PHPMyAdmin to import your .sql


STEP 4: UPLOAD YOUR CAKEPHP FILES

	# Using FTP software (like Transmit), upload all the files in your CakePHP application to:
	/var/www/vhosts/example.com/subdomains/mysubdomain/httpdocs

	# Don't forget to upload your .htaccess files. Your FTP software may treat them as hidden files and skip them in the upload process. (If you're using Transmit, select View -> Show Invisible Files to make sure they are uploaded.)

	# Don't forget to update your app/config/database.php file so your app will connect to the production database.


STEP 5: FIRE IT UP

	# Point your browser to http://mysubdomain.example.com
