<U4>
hello all
13:44
<Hyperbyte>
Hi.
13:49
<U4>
me and a friend were wondering
13:50
can you do NX style session save and restore (possibly on a different client) in LTSP
13:53
<Hyperbyte>
Sure, although by default LTSP only support RDP I think.
13:53
You should be able to create a custom startup script for FreeNX though, and install FreeNX into the client chroot.
13:54
There's some info on it here http://www.telemedia.ch/publ/ltsp-howto.html (at the bottom of the page)
13:55
<U4>
is that not just using NX? and only using LTSP trun the NX Client? :p
13:56
<Hyperbyte>
Yes, what else were you looking for?
13:57
<U4>
sorry, not quite what i was thinking of
13:59
<Hyperbyte>
Then what were you thinking of?
14:00
<U4>
i was just thinking of for example i lock my ltsp session, and restore it from another client
14:00
we have two rooms in our office, and i work in both of them
14:01
<Hyperbyte>
Ah.
14:01
Well, for that you should stick around 'till someone who knows the answer to that comes along. :)
14:01
<U4>
if i wanted to use NX, i'd use NX :p (NX sucks)
14:01
heh ok
14:01
<Hyperbyte>
I misread your question a little.
14:02
<U4>
]dw
14:02
*dont worry
14:02
<Hyperbyte>
I never do. :)
14:04
<alkisg>
U4: X doesn't support suspend and resume, so you'd need some kind of an x-proxy for that
14:05
<U4>
aah
14:05
thanks :)
14:05
<alkisg>
See the nomad project, I think they've done something similar
14:05
<Hyperbyte>
Oh, hi Alkis. :)
14:05
<alkisg>
Hi Hyperbyte
14:05
<Hyperbyte>
Things ok in Greece? :)
14:06
<alkisg>
Just fine - just came back from mountain hiking, my feet hurt after 2 days of climbing... :D
14:07
U4: why do you think that NX sucks? It's working fine for me...
14:08
I'm using it for remote access to my ltsp server from home, and even allowed some of the students to do that as well..
14:08
<U4>
usb devices, sound, video...
14:09
we have a few in the department, even over lan, they cant actually do anything well
14:10
<alkisg>
Which server are you using? The proprietary one or e.g. freenx?
14:11
<U4>
prop
14:11
maybe it's just a bad experience that's put me off
14:13
ltsp is several universes better than NX, but it still doesnt come close to actual real cloned machines
14:13
<alkisg>
LTSP with fat clients is exactly like cloned machines, performance-wise
14:14
<U4>
ooh
14:14
<alkisg>
NX uses compression etc, so for video it'll of course be much worse than plain X
14:14
<U4>
aye
14:14* alkisg hopes the openssh guys finally allowed the null cipher, for ssh without compression...
14:14
<U4>
?
14:15
<alkisg>
Then all the programs that use ssh could do it without compression/encryption, i.e. without any overhead, useful for trusted environments where speed matters more than security
14:15
<U4>
ssh is compressed?
14:15
<alkisg>
So nx there would be very fast
14:15
<U4>
i thought you had to request it with -C
14:15
?
14:16
<alkisg>
ssh e.g. => 10 MB/sec, plain X traffic => 100 MB/sec on the same hardware
14:16
Encryption makes it much slower
14:16
<U4>
aah
14:16
<alkisg>
It also has compression parameters, yes

<dubkat>
probably not. you could just use xdmc or whatever its called
23:42
<alkisg>
xdmcp. Why? The current ltsp solution is better, it uses ssh for secure authentication + xauth magic afterwards
23:43
But if ssh allowed the null cipher, it would make everything easier, not only with ltsp
23:43
E.g. nx in LAN would be much faster
23:43
(allowing for suspend+resume sessions, which xdmcp/ltsp can't)
