Ssh

Zo. Zat van iedere keer te moeten pielen.. Alhier mijn online kladblok.. Waarschijnlijk ooit een volledig script..

# 1. create keyfile. Remove -N to use a password.
ssh-keygen -t rsa -b 4096 -N -CMyPuter -f.ssh/my.slurver.tld

# 2. enable password login
# as root on the server
sed -i -r 's/#?\s*(PasswordAuthentication\s+)no/\1yes/g' /etc/ssh/sshd_config
service ssh restart

# 3. upload keyfile
cat ~/.ssh/my.slurver.tld.pub | ssh me@my.slurver.tld "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys"

# 4. disable password login
# as root on the server
sed -i -r 's/#?\s*(PasswordAuthentication\s+)yes/\1no/g' /etc/ssh/sshd_config
service ssh restart

# 5. create an easy entry
echo "Host slurver" >> ~/.ssh/config
echo "Hostname my.slurver.tld" >> ~/.ssh/config
echo "User me" >> ~/.ssh/config
echo "IdentityFile ~/.ssh/my.slurver.tld" >> ~/.ssh/config
echo "DynamicForward 9999" >> ~/.ssh/config
echo "" >> ~/.ssh/config
chmod 600 ~/.ssh/config

# some ssh restart commands to try
sudo service ssh restart
sudo service sshd restart
sudo systemctl reload sshd.service
