We have a service that we start up remotely with rsh but unfortunately, the rsh never returns to the calling server. This seems to be because the processes of the service we've just started hold the port open.
When run locally on the command line, all is well with the simple script and I can log off the session without issue or other prompt. When called with rsh, the script called does complete (we have logging to show that), so I'm wondering how I can disinherit/detach the service processes started up.
Server where script will run is AIX 5.1 and the server calling is RHEL 6.3
Suggestions would be most welcome. Many thanks, in advance,

Cancel that. I managed it with a nohup xxxxx & call to start the service inside the script.

Hi. !
When I use the 'NOHUP' along with the '&', the process will be running in the background. Even when I attempt to close (Meaning 'EXIT') the session (say PUTTY in this case), it wont exit unless the process is completed.

RSHD(8) BSD System Manager's Manual RSHD(8)NAME
rshd -- remote shell server
SYNOPSIS
rshd [-aiklnvxPL] [-p port]
DESCRIPTION
rshd is the server for the rsh(1) program. It provides an authenticated remote command execution service. Supported options are:
-n, --no-keepalive
Disables keep-alive messages. Keep-alives are packets sent at certain intervals to make sure that the client is still there, even
when it doesn't send any data.
-k, --kerberos
Assume that clients connecting to this server will use some form of Kerberos authentication. See the EXAMPLES section for a sample
inetd.conf(5) configuration.
-x, --encrypt
For Kerberos 4 this means that the connections are encrypted. Kerberos 5 can negotiate encryption even without this option, but if
it's present rshd will deny unencrypted connections. This option implies -k.
-v, --vacuous
If the connecting client does not use any Kerberised authentication, print a message that complains about this fact, and exit. This
is helpful if you want to move away from old port-based authentication.
-P When using the AFS filesystem, users' authentication tokens are put in something called a PAG (Process Authentication Group). Multi-
ple processes can share a PAG, but normally each login session has its own PAG. This option disables the setpag() call, so all tokens
will be put in the default (uid-based) PAG, making it possible to share tokens between sessions. This is only useful in peculiar
environments, such as some batch systems.
-i, --no-inetd
The -i option will cause rshd to create a socket, instead of assuming that its stdin came from inetd(8). This is mostly useful for
debugging.
-p port, --port=port
Port to use with -i.
-a This flag is for backwards compatibility only.
-L This flag enables logging of connections to syslogd(8). This option is always on in this implementation.
FILES
/etc/hosts.equiv
~/.rhosts
EXAMPLES
The following can be used to enable Kerberised rsh in inetd.cond(5), while disabling non-Kerberised connections:
shell stream tcp nowait root /usr/libexec/rshd rshd -v
kshell stream tcp nowait root /usr/libexec/rshd rshd -k
ekshell stream tcp nowait root /usr/libexec/rshd rshd -kx
SEE ALSO rsh(1), iruserok(3)HISTORY
The rshd command appeared in 4.2BSD.

This implementation of rshd was written as part of the Heimdal Kerberos 5 implementation.
