Problems when start CDE from Reflection X

Eric TAO — Tue, 03 Apr 2007 04:55:28 GMT

Hi ALL,

I just installed a HPUX 11i V1 on rp4440. it's working fine with telnet and REXEC shell, but, when i try to use Reflection X to start the X Windows, it prompt me "The Desktop Messaging System could not be started". What should i do with this? i have no idea on it, since network and hosts are already configured properly.

Please help.

Thanks

ths can be a sign that name resolution is not working correctly

nslookup ip --> returns hostname
nslookup hostname --> returns ip address
check /etc/hosts, /etc/rc.config.d/netconf, etc.
since this is a new system it's likely that you need to run set_parms to set the correct parameters

Reflection/X is simply an Xwindow emulator so before you try to start CDE (the Desktop manager), use telnet to login to your HP-UX server, then use:

export DISPLAY=$(who -muR | awk '{print $NF}'):0.0

to set your PC's hostname or IP address. Now run xclock from your telnet session. If the clock pops up on your PC, everything is setup for Xwindows and you now have to setup the CDE Desktop Manager on HP-UX.

Hi Cheryl and Bill,

Thanks for your reply, actually, I did follow you 2 instructions to fix the CDE problem, but, the same error message keep prompts to me, anyway, below is my results:

1. nslookup ip/hostname = successful to resolve

2. configured "export DISPLAY=$(who -muR | awk '{print $NF}'):0.0" via REXEC under Reflection X, and then type "xclock" = successful to show the clock popup on my PC.

And now, what should i do? where can i setup my CDE? many many thanks

Hi Eric,

How do you resolve ip's/hostnames, DNS or the local /etc/hosts file?

# ll /etc/nsswitch.conf
# cat /etc/nsswitch.conf

If you don't have the nsswitch.conf file, cp the /etc/nsswitch.files to the nsswitch.conf.

Reagrds,
Robert-Jan

Hi Robert-Jan,

Yeah, it's working now, many thanks for your help.

BTW, if i would like to create new user with the root privilege, then, is it just simply assign into UID 0?

Best Regards

I would suggest not to create a second root user, have a look at sudo.

>Error: Can't open display: 10.37.93.100:0

Where/what is 10.37.93.100? Do you have an Xserver running there?

Also, I typically have to use: ... :0.0
