<gdi2k>
I have a fat client set up with about 10 clients and a medium powered server (Phenom 2 X4 955, 8GB RAM, RAID1 SSDs and RAID1 2TB disks). Clients and server are on 1 GB LAN. I've noticed high IO Wait on the server when most users are logged in. Disk activity seems very low, but interrupt activity points to the culprit being eth0. How many clients per server would be reasonable in such a set up?

First try to see which process is causing the bottlenecks you see
05:08
We have schools here with much worse servers than yours and e.g. 30-40 clients

excellent, thank you. will go digging...

How i can poweroff thin client when they are unused since 1h ?
09:44work_alkisg has joined IRC (work_alkisg!~alkisg@plinet.ioa.sch.gr)
09:45
<jmilot>
Can we create a script to halt a thin client when nobody is connected ?

<jmilot>
Hi alkisg
09:47
<alkisg>
Hello
09:48
<jmilot>
how are you ?
09:48
I succeed to launch epoptes using gpassword
09:49
<alkisg>
Your group required a password?
09:50
<jmilot>
no i used gpassword -a username group
09:51
i don't know if it can be linked but i use a ldap server for authentification
09:51
<alkisg>
You mean gpasswd?
09:57
<jmilot>
yes sorry
09:57
<alkisg>
Yup it's mentioned in http://www.epoptes.org/installation
09:58
<jmilot>
we need to do it even the user belong to the group ?
09:59
<alkisg>
No, but if the user can't access the socket AND belongs to the group then there's something wrong with your setup
09:59
See also the epoptes questions about ldap
09:59
(which mention that ldap needs to start before epoptesd)
10:00
<jmilot>
ok i will see
10:00
i have an other question how to improve th screen refresh on thin client ?
10:01
<alkisg>
!directx
10:01
<ltsp_>
directx: If you want to turn off encryption to the workstation, which will speed up performance at the cost of security, you need to specify LDM_DIRECTX=True in your lts.conf file. Type !docs in IRC to get a link to the current documentation
10:01
<alkisg>
You mean something like that?
10:07
<jmilot>
yes but i have already put this option
10:08
<alkisg>
Give more details. What you see, why you think it's slow, why you think it can be faster etc.
10:09
E.g. if you have 100 mbps networking, that's the issue, but it's difficult to ask you all the possible bottlenecks, you need to describe the setup yourself

Reset the webserver, that seems to have brought things back at least somewhat I think...
