The additional difficulty I have is that I some times use standard X11R4 and wish different binaries for xterm etc. I hacked xrsh to xnrsh (Xnews rsh) to do the trick. The point is to pass the environment variable NEWSSERVER and use it to select PATHs. put the following in your ~/.setpaths -------------------------------------------------- setenv OPENWINHOME /usr/openwin if ( $?NEWSSERVER == 1 ) then setenv PATH .:$HOME/bin:/usr/local/bin:/usr/ucb:$OPENWINHOME/bin:$OPENWINHOME/bin/xview:$OPENWINHOME/demo:/usr/bin/X11:/usr/bin:/bin setenv MANPATH $OPENWINHOME/man:/usr/local/man:/usr/man eval `svenv -env -csh` else setenv PATH .:$HOME/bin:/usr/local/bin:/usr/ucb:/usr/bin/X11:/usr/bin:/bin:$OPENWINHOME/bin:$OPENWINHOME/bin/xview:$OPENWINHOME/demo setenv MANPATH /usr/local/man:/usr/man:$OPENWINHOME/man endif -------------------------------------------------- and put the shell script xnrsh in your ~/bin -------------------------------------------------- #!/bin/sh # case $# in 0|1) echo "usage: $0 host cmd [args]" 1>&2; exit 1;; esac case "X$DISPLAY" in Xunix:*) : ${HOSTNAME=`hostname`} DISPLAY=`echo "$DISPLAY" | sed -e "s/^unix:/${HOSTNAME}:/"` ;; X:*) : ${HOSTNAME=`hostname`} DISPLAY="$HOSTNAME$DISPLAY" ;; esac commands=${DISPLAY:+"setenv DISPLAY $DISPLAY ;"}\ ${NEWSSERVER:+"setenv NEWSSERVER \"$NEWSSERVER\";"} host="$1" shift exec rsh "$host" -n " $commands source .setpaths ; exec $@ " -------------------------------------------------- You should rlogin to a remote host by doing > xnrsh remote_host xterm or > xnrsh remote_host cmdtool > xnrsh remote_host emacs Of course, you will need to set up .rhosts on machines so that you can login w/o a passwd. And don't forget to pass Xauth infomation or use xhost to add the remote_host to the access list. This is the most satisfaction solution I have found so far. Does any body have any better ideas?
