Run Linux/MQSC commands from mq client

Ok, I want to check if I can run some OS or MQSC commands in MQ server remotely. As long as I know, this could be done with SYSTEM.ADMIN.SVRCONN. In order to do that, I add a remote Queue Manager to my WebSphere MQ client. I put Queue Manager name on the server with proper IP, but when I use SYSTEM.ADMIN.SVRCONN as channel name, I have got: Channel name not recognized (AMQ4871) error.

Also, if I have a channel name like MY.CHANNEL.NAME and it is a server-connection channel with mqm as its MCAUSER, can I run some commands (MQSC or OS) through this channel on the server?

Thanks.

I am using WebSphere MQ v.7.0

By "I add a remote Queue Manager to my WebSphere MQ client" I meant I added a remote queue manager to MQ Explorer.
