dnetcat {-h|--help} dnetcat [-v] [-z] node[::|[::] ]object dnetcat [-v] [-f] -l object DESCRIPTION
dnetcat is a netcat(1) like tool that opens a DECnet connection and copies all data between the standard input/output to/from the socket. OPTIONS
-v Be verbose. Prints useful (debug) messages. -z Zero IO mode. In this mode a connection is dropped directly after it is opened. This can be used to scan if the remote side listens on the given address and object. -l Listen mode. In this mode dnetcat accepts connections on the given object. -f Fork on new connection. This let netcat accept multiple connections in listen mode. This is ignored if -l is not given. --help, -h Prints a small help. EXAMPLES
This program can be used as 'ProxyCommand' for ssh(1). You may use it via command line like this: ssh -o 'ProxyCommand dnetcat %h ssh' [...] mynode or you may use it in your ~/.ssh/config like this: Host *:: ProxyCommand dnetcat %h ssh This will enable you to connect to any DECnet node by adding "::" at the end of the node name like this: ssh mynode:: For more information on ssh(1) see it's manpage.
