Crashplan for Dummies, aka Step by Step :)

I've tried to follow the initial guide however am running into problems; i must of mistyped a port forwarding and now do not know how to get rid of it.

Updated my ui.properties without any issues

#Fri Dec 09 09:50:22 CST 2005
#serviceHost=127.0.0.1
servicePort=4200
#pollerPeriod=1000  # 1 second
#connectRetryDelay=10000  # 10 seconds
#connectRetryAttempts=3
.....=

SSH into the nas and run tried to forward the port using root

NAS:~# ssh -f -L 4200:localhost:4243 root@192.168.118.17 -N
root@192.168.118.17's password: 
bind: Address already in use
channel_setup_fwd_listener: cannot listen to port: 4200
Could not request local forwarding.

Used to the following command to find if it was forwarded okay however only see 4200 and not 4243

SmellyNAS:~# netstat -na | grep LISTEN | grep 4 
tcp        0      0 0.0.0.0:2049            0.0.0.0:*               LISTEN

tcp6       0      0 :::548                  :::*                    LISTEN     
tcp6       0      0 ::1:4200                :::*                    LISTEN     
tcp6       0      0 :::443                  :::*                    LISTEN     
unix  2      [ ACC ]     STREAM     LISTENING     3421     /var/run/acpid.socket

Does any one know how to delete the 4200 forwarding?

Output as per Crashplan website is
Output should look like this:

username$ netstat -na | grep LISTEN | grep 42
tcp4       0      0  *.4242                 *.*                    LISTEN
tcp4       0      0  127.0.0.1.4243         *.*
