REMSH Service

Using remsh

MPE/iX Examples

To run remsh from MPE/iX prompt, type:

run remsh.net.sys;info="remotehost -l remoteuser remotecommand"

jhereg(PUB): run remsh.net.sys;info="taltos -l cawti pwd " /u2/home/cawti

END OF PROGRAM

jhereg(PUB):

POSIX Examples

From the POSIX Shell prompt, type:

/SYS/NET/REMSH remotehost -l remoteuser remotecommand

shell/iX> /SYS/NET/REMSH taltos -l cawti pwd

/u2/home/cawti

shell/iX>

There are a number of shell features that can be taken advantage of,

while running under the POSIX shell.

Shell metacharacters that are not quoted are interpreted on the local

host; quoted metacharacters are interpreted on the remote host. Thus

the command line:

/SYS/NET/REMSH taltos -l cawti cat remotefile >> localfile

appends the remote ﬁle remotefile to the local ﬁle localfile, while

the command line:

/SYS/NET/REMSH taltos -l cawti cat remotefile ">>" otherremotefile

appends remotefile to the remote ﬁle otherremotefile.

The following command line runs remsh in the background on the local

system, and the output of the remote command comes to your terminal

asynchronously:

/SYS/NET/REMSH otherhost -l remoteuser -n remotecommand &

The following command line causes remsh to return immediately

without waiting for the remote command to complete:

/SYS/NET/REMSH otherhost -l remoteuser "remotecommand 1>&- 2>&- &"

remsh was written so that if the ﬁrst parameter in its argument vector

is not remsh, it will use the value as a host name. So you may

symbolically link the host name to the remsh program. A typical BSD

UNIX implementation will have these links under the /usr/hosts

directory.

If you have made a symbolic link to the remsh program that is the host

name, for example you have already entered, (ln -s /SYS/NET/REMSH

taltos in our examples), you could simply generate the same result as

the ﬁrst example with the following:
