Diskless problems

I have got most of the way there and can boot my Thinkpad and a Shuttle to thier respective adressess/ workstations . But , niether start BOINC .
on the screen the last few lines go something like : -
could not load host key /etc/ssh/ssh_host_key
could not load host key /etc/ssh/ssh_host_rsa_key
could not load host key /etc/ssh/ssh_host_dsa_key

etc/rc.sysinit: line448: /etc/rc.d/runboinc: cannot execute binary file
rc.sysinit completed, switching to multi-session mode

I have used Mojos files and scripts edited to reflect my network , also DTs ‘start_boinc’ script renamed. I have made sure that the relevant files are executeable. but the same result on both.

any ideas ???

2

look at the run boinc and make sure it is executable (ls -l)
may require a chmod 777 run_boinc.sh

3

yep… runboinc (both versions ) are executable , both give the same result . :frowning:

4

in the directory where you have the Boinc exe, check those for the same.

Yes the boinc exe is ok , first thing I checked ,
I have just been going over your instructions

Now referring back slightly again, I previously mentioned that not all files from the “full” install were in the /opt/ltsp/i386 tree. You will need to copy three files into the correct locations.

/lib/libproc.so.3.2.0 copy to /opt/ltsp/i386/

I dont seem to have this file , the closest I’ve got is libproc-3.2.3.so that I copied over instead .

Can you run the boinc client from the machine manually? If you change your lts.conf and specify

SCREEN01 = shell

for the node it will leave you at a command prompt.

Sorry for the delay , I got dragged out ‘shopping’ by the wife , I’m being accused of neglect . :rolleyes: , If i start boinc manually I get something like ‘BOINC is already running’ although this is not so
various scenarios usually end in messages to the the effect that permission is denied (nohup out) or read only environment . it seems that apps are not running locally for some reason.
So I am going to start from scratch again ( I’ve got a SAMBA config problem as well ). new processor and memory , switch and cables arrived today for the new network configuration and client.(5 hard drives and hopefully some GFX cards = 1 diskless crunchers leccy :xfinger: )

changed the ws0XX folder ownership from ‘root’ to ‘nfsnobody’ bingo it works .

time to resurrect an old thread as a Google to help got me here :lol:

Which folder ownership ? I’ve just moved my server to the latest ltsp and I now have the same bits and errors as described in this thread.

nice little bit on ssh http://ltsp.sourceforge.net/ltsp-4.html#localapps although when I try to ssh to the nodes from the server I’m not able to login and logs are showing “sshd[1167]: Failed password for root from 192.168.40.254 port 40579 ssh2” when using the root password from the server. So how to set the ‘nodes’ password when the command ‘passwd’ doesn’t exist … :shrug:

This’ll teach me for playing, I should have kept the Gentoo version I had running yesterday, but decided it would be nice to have a k12 as I kinda convinced Balrog to do so with his net cafe type thing !! :lol:

When I created the ws0xx folders in /home I was in root , so the permission and folder/file owner were set to ‘root’ meaning no other processes had access and could not start the executables .
(right click , properties , permissions.)

teehee, right click ??? chown :smiley:

I think I’ve woke up and smelt the coffee this morning for my problem with running nohup, top etc. The server is x86_64 and of course ltsp is i86 :doh:

I’m about to try extracting the right bits out the i386 install disks.

:smiley: an anathema to Linux purists I know , but I dont use it enough to get familiar with the command line stuff, so mouse clicks if possible all the time for me , why use the chmod command when I can achieve the same thing without using the keyboard at all .

13

Only for the reason that once you know command-line processing you can then use shell-scripting to chain commands together conditionally and do this stuff literally hundreds of times quicker.

For single folders or trees can’t see it makes the slightest difference which method or interface you use :slight_smile:

14

as my new job involves so much work from command line on web servers, I’ve kinda go used to just using the keyboard and not the rodent :slight_smile: I guess you could say that I’m getting rather geeky in that I do love the sight of a black background and green text :lol:

But on the other hand, for home use, I think that I will have to look at some custom monitors in webmin for folding and boinc. Web based interface to control the server is rather smart :thumbsup:

:amstupid: I spent a good hour last night trying to work out what it was - nail head after first coffee this morning :coffee:
