SSH and SCP with a username specified

[ldmtwo]

Could you add a feature and configuration that would allow specifying the user name? That way with SSH_KEY and the proposed USER config, the tool will be able to specify the rest of this.

From this_user@localhost:
ssh -i ~/.ssh/id_rsa THAT_user@remotehost

Below is the minimal solution to the above request. I added the USR variable and an echo of the actual command. Previously I was getting authentication errors because the user name was different.

This is the bottom of the common.sh file.

USR="hadoop@"
ssh_w() {
        h=$(echo $1 | cut -d: -f1) # hostname
        p=$(echo $1 | cut -d: -f2 -s) # port
        shift
        if test -z $p; then p=22; fi
        echo ssh $_ssh_key -p $p $USR$h "$@"
        ssh $_ssh_key -p $p $USR$h "$@"
}

scp_to_w() {
        # do not use as first parameter dir/*, use this between quotes
        # i.e "dir/*" (prevents shell expansion)
        h=$(echo $1 | cut -d: -f1) # hostname
        p=$(echo $1 | cut -d: -f2 -s) # port
        shift
        if test -z $p; then p=22; fi
        echo scp $_ssh_key -p -r -P $p $1 $USR$h:$2
        scp $_ssh_key -p -r -P $p $1 $USR$h:$2
}

scp_from_w() {
        # do not use as first parameter dir/*, use this between quotes
        # i.e "dir/*" (prevents shell expansion)
        h=$(echo $1 | cut -d: -f1) # hostname
        p=$(echo $1 | cut -d: -f2 -s) # port
        shift
        if test -z $p; then p=22; fi
        echo scp $_ssh_key -p -r -P $p $USR$h:$1 $2
        scp $_ssh_key -p -r -P $p $USR$h:$1 $2

}
