Client Application sc

Anetd's client application (sc) assists in issuing control commands formatted using ANEP and creating digital signatures for authentication. sc looks for the file $HOME/.anetd/id_secretkey and find the corresponding 512-bit private key associated with the clientid by the client. (if client doesn't input a client ID at the command line, sc will by default use the first private key it can find in the file $HOME/.anetd/id_secretkey).

After a valid 512-bit key is found, it creates a digital signature of the user command. The signature includes a timestamp to avoid replay attacks and is sent together with the command to the specified Anetd daemon. The sc command line usage is

sc [-q | -v] [-h] [-t timeout] [-p t|u] [-i client_id] [-f username]
   servername[:port] cmd args

• -q be quiet
• -v be verbose
• -h print this help
• -t specify the timeout for network operations (default 10 sec)
• -p specify transport protocol to use (t = TCP, u = UDP)
• -i specify which client ID to use
• -f forward to the secondary anetd with specified username
• servername[:port] hostname and port where anetd is listening (default 3322)
• $<$cmd$>$ is one of the Anetd commands (see Section 3.8).
• args args to the control command $<$cmd$>$
