How to run netscape navigator with rsh and DISPLAY?
I want to launch Netscape Navigator
The 6000 port on my host is open
the host is added using xhost+
host + 192.168.0.33
If I did
rlogin 192.168.0.33
and then
export DISPLAY=192.168.0.2:0
navigator
Works fine.
But I want to run directly on host I have tried
rsh 192.168.0.33 DISPLAY=192.168.0.2:0 navigator
and
DISPLAY=192.168.0.2:0 192.168.0.33 navigator
and
export DISPLAY=192.168.0.2:0
rsh 192.168.0.33 /usr/bin/navigator
and
rsh 192.168.0.33 "export DISPLAY=192.168.0.2:0 ; /usr/bin/navigator"
But don’t work
Why?
FAQ
Q: Why not ssh which is simpler and more secure?
A: This is an old host, ssh2 is not supported
Q: Why use a very old browser?
A: Is for turn on an old Bare-metal ibm server which use very old ssl protocols (ssl2, rc4 and other weak tools) for remote manage via ASMI , the modern browser has ssl3 and tls 1.1 disabled so cannot open a webpage "protected" using ssl2
Q: Why don’t upgrade ASMI?
A: This server is discontinued since 10-15 years
Solution found, was a firewall problem. I don’t know why but seems on Slackware rsh the port 1021/tcp needs to be open for rsh connections.
The line
xhost +192.168.0.33
rsh 192.168.0.33 DISPLAY=192.168.0.2:0 navigator
works fine
For a more secure environment I will try ssh + a browser configured for very old ssl and rc40 in a vm next time.
