I'm really impressed by what a little discussion on YouTube with @Irinikus can give 48h later …

@Irinikus : Do you use OpenSSH ou Dropbear ?

@Raion : Thanks a lot for Optxeno. I've followed your instructions to extract and install Optxeno and to activate Dropbear but when I do :

Code:

# /opt/xeno/sbin/dropbearkey -t ecdsa -s 521 -f /opt/xeno/etc/dropbear/host.key

The console repond :

Code:

1630:/opt/xeno/sbin/dropbearkey: rld:Fatal Error: Cannot Succesfully map soname 'libz.so.1' under any of the filename ./libz.so.1:/usr/lib32/libz.so.1:/usr/lib32/internal/libz.so.1:/lib32/libz.so.1:/opt/lib32/libz.so.1:

Your LD_LIBRARYN32_PATH isn't set.

If you're using tcsh: setenv LD_LIBRARYN32_PATH /usr/lib32:/lib32:/opt/xeno/lib32:/opt/lib32

you'll need to add other paths you use for things like nekoware or whatever to it.

You should add that to your .cshrc -- if you're using bash or ksh, it's using export LD_LIBRARY_PATH=/usr/lib32:/lib32:/opt/xeno/lib32:/opt/lib32 and needs to go in the rc for that.

If you're not sure, echo $SHELL.

@Irinikus : Do you use OpenSSH ou Dropbear ?

The first examples that I showed were using ssh, and the last example was xdm (X Display Manager).

@ Raion : Thanks for your answer That's true, if I don't write de path in my .cshrc file, it can't works

@ Irinikus : XDM works immediatly. No need to configure anything … or perhaps something is open by default on my SGI and I never knew it.


After, I don't know the real difference beetwen SSH and XDM … I've to read some informations about it.

[Raion]

XDMCP is the native X Windows way of logging in remotely via X to a server. It's super insecure. SSH is usually used to tunnel X traffic because you can literally sniff it out on the same network or clearnet.

As for what SSH is, it's a replacement for BSD's rsh, and the UNIX telnet services, basically these are "remote access" that only works with shell commands. SSH adds encryption and key hash authentication. This does two things -- it allows you to prove that both ends of the connection are only between those two parties (no man-in-the-middle), and that the traffic is obfuscated. SSH is a generalized protocol, unlike XDMCP.

I assume XDM probably has much lower overhead and may perform better? Just an assumption though.

This feels like an old thread but from one X11 forwarder to another, I can't recommend MobaXterm enough for Windows users.

If you're using Linux and OSX then what you've put in the thread here is a great update, my thanks.

Have been using XDM for quite a while, simple and easy, on a private network so not worried about any issues. Would not try heavy graphics over it but for system maintenance and such, works like a charm.

Hi Raion, Shiunbird & Co,

yes XDMCP is not secure, but it is simple ;-) .

I doubt any of these hobby SGI boxes are directly connect to public network.

If you did want to access your SGI box remotely (via GUI), I expect that you would put it behind a firewall and punch through via VPN tunnel...

yes

Hi Shiunbird,

the advantage is that it is simple, as protocol does the work for you.

I read lots and lots of complicated approaches, but fail to see the point in these if "X -query <IP>" works ...

Using other approaches can achieve the result, but unless you know the details of how X works (client / server arch, DISPLAY use, IP Ports etc) diagnosing problems is difficult.

Hence my keep it simple appraoch/
