How to send mail to Gmail
If you are on Debian 7 as of 16/09/2013 I would advise doing the following:
Add the following line:
deb http://ftp.uk.debian.org/debian wheezy main contrib
Then follow this guide: http://www.cyberciti.biz/tips/linux-use-gmail-as-a-smarthost.html
Afterwards comment out the new /etc/apt/sources.list line and do apt-get update again.
apt-get install monit vim /etc/default/monit
Set startup=0 to startup=1
The config file is /etc/monit/monitrc
set httpd port 2812 use address 220.127.116.119 # only accept connection from localhost allow 0.0.0.0/0.0.0.0 # allow localhost to connect to the server and allow admin:password # require user 'admin' with password 'password'
If you use mutt to send emails via scripts and get this message because the attachment is too large:
postdrop: warning: uid=0: File too large sendmail: fatal: root(0): message file too big Error sending message, child exited 75 (Deferred.). Could not send the message.
DO NOT install exim (especially if you have Proxmox installed) to try and solve the issue as it will do the following:
apt-get install exim4

If you start getting the following message:
mailx Can't send mail: sendmail process failed with error code 67
And you can't start Apache, you need to re-install pve-manager.
error code 67
If you get this error message when sending mail to a domain with mail externally but it is on the server:
Can't send mail: sendmail process failed with error code 67
Add the domain to this file and restart sendmail:
vim /etc/mail/relay-domains /etc/init.d/sendmail restart
It is commonly easier to use this to dump and restore MySQL, instead of using mysqldump on the new server via .sql files:
mysqldump --default-character-set=binary --user=root --password=EnterPasswordHere databasename > dbdump.txt
mysql --silent --local --password=EnterPasswordHere DatabaseName < dbdump.txt
Deleting large file/s fails and crashes NAS
Install mplayer on Debian Wheezy
Add the following lines to your /etc/apt/sources.list file:
# Debian Multimedia Repository deb http://www.deb-multimedia.org wheezy main non-free deb ftp://ftp.deb-multimedia.org wheezy main non-free
apt-get update apt-get install deb-multimedia-keyring apt-get update apt-get install libimage-exiftool-perl ffmpeg apt-get install mplayer mencoder
Then comment out the following lines to your /etc/apt/sources.list file:
# Debian Multimedia Repository #deb http://www.deb-multimedia.org wheezy main non-free #deb ftp://ftp.deb-multimedia.org wheezy main non-free
And run apt-get update again.
This can be needed to also get mencoder working as well.
mediainfo and dcraw should install normally without the above packages.
vlc and vlc-nox will ask to remove some of the packages that were installed above.

apt-get update fails due to static IP + DNS
Or you can just install NTP (Network Time Protocol) using:
apt-get install ntp
Speed up SSH login
By default for some reason in Debian 6 (Squeeze) /etc/ssh/sshd_config does not have UseDNS=no within it. Add it into the file and restart SSH and this will greatly improve SSH login as a sudo user or root. GSSAPIAuthentication=no may also help.

apt-get install vim ncdu
The easiest way to get this working is by doing:
Add in this line:
deb http://ftp.uk.debian.org/debian sid main
Do apt-get update , then do:
apt-cache show transmission-cli | grep Version apt-cache show transmission-common | grep Version apt-cache show transmission-daemon | grep Version
apt-get install transmission-cli transmission-common transmission-daemon
Then, to edit the files without it overwriting /etc/transmission-daemon/settings.json
Stop the service, edit the file, backup the file and then start the service.
/etc/init.d/transmission-daemon stop vim /etc/transmission-daemon/settings.json cp /etc/transmission-daemon/settings.json /root/settings.json.backup /etc/init.d/transmission-daemon start
Check /etc/transmission-daemon/settings.json is the same file you edited and that it is owned by debian-transmission:debian-transmission
User has the wrong group
For example you want the files of the User tester to have the following User:Group setting:
However the system is creating files as tester:anotherGroupOrUser To resolve this log in as root and do:
usermod -g tester tester
This will set the tester User's primary group as tester.
If you are using a Vanilla build of a Unix OS you will need to do this so themes and plugins can install:
