Problem

So instead of typing this:

ssh 12.34.56.78 -p 2424 -i ~/.ssh/id_dsa_keyone -l lingtalfi 'mysqldump -usketch -pZERj07Fe1 sketch'

You want to type this:

ssh conn1 'mysqldump -usketch -pZERj07Fe1 sketch'

Create the ~/.ssh/config file if it doesn't exist, and put the following content in it:

Host conn1
    HostName 12.34.56.78
    User lingtalfi
    IdentityFile ~/.ssh/id_dsa_keyone
    IdentitiesOnly yes
    Port 2424

You can create as many "Host" sections as you want.
