------------------------


The man page sge_conf states for

rlogin_command
rlogin_daemon
rsh_command
rsh_daemon

to use the qlogin examples, hence telnet and in.telnetd to fall back to the old startup method. I would
expect there:

$SGE_ROOT/utilbin/$ARC/rlogin
/usr/sbin/in.rlogind
$SGE_ROOT/utilbin/$ARC/rsh
$SGE_ROOT/utilbin/$ARC/rshd

to be listed instead. I can put an absolute path there, but it can't be generic like in former times, hence
I need local configurations in a mixed environment now.

The complete entries which must be entered to fall back are:

qlogin_command               /usr/bin/telnet
qlogin_daemon                /usr/sbin/in.telnetd
rlogin_command               /usr/sge/utilbin/lx24-x86/rlogin
rlogin_daemon                /usr/sbin/in.rlogind
rsh_command                  /usr/sge/utilbin/lx24-x86/rsh
rsh_daemon                   /usr/sge/utilbin/lx24-x86/rshd -l

Besides giving this exact information what will be called is necessary to setup any calls:

qlogin_command will be called with the parameters "$HOST $PORT"

rlogin_command will be called with "-p $PORT $HOST" (for now it states the opposite order: "...started
with the target host and port number as parameters." in man sge_conf)

rsh_command will be called with "-n -p $PORT $HOST" (for now it states the opposite order and it would
conform to telnet: "...the target host and port number as parameters like required for telnet(1) plus..." in
man sge_conf. The order is of course wrong.)

Add on: the section for qlogin_command refers to "qlogin_command /usr/bin/telnetd", it must read
"qlogin_command /usr/bin/telnet".
