<rickogden>
hi, anyone able to help me with getting local devices to mount on the server? I've been through the steps on the ubuntu page, but not sure where I should go from here
08:32
<Gadi>
rickogden: you should have the "ltspfs" package installed on the server and the user you login a should be a member of the "fuse" group
08:32
<maslak>
is there any way to use vnc instead of running X directly on client ?
08:32
<rickogden>
Gadi: yes, both are the case
08:32
<Gadi>
maslak: vnc is not a replacement for X
08:33
<maslak>
it was my mind shortcut ;)
08:33
<rickogden>
maslak: you need X (or another supported platform) to run VNC on in the first place
08:33
<alkisg>
maslak: what problem are you facing?
08:33
<Gadi>
rickogden: same question
08:33
:)
08:34
<maslak>
when i try to run some heavy apps on thin client - i see huge usage of cpu andd memory, program is killed, or my X session is restarted (i see ldm login screen again)
08:34
problem is only when i try to run wine
08:35
<rickogden>
Gadi: I've been through https://wiki.ubuntu.com/DebugLocalDev and all apart from the final step is correct, but I'm not sure what is happening when I try to manually run the command (in step 4)
08:35
<alkisg>
maslak: And that doesn't happen if you run that wine app on a non-ltsp client or on the server?
08:35
It only happens on ltsp clients?
08:35
<maslak>
exactly UniPaas enviroment, which works fine locally on server or standalone machine
08:35
<alkisg>
Have you tried with LDM_DIRECTX=True?
08:35
<Gadi>
rickogden: you mean "id"?
08:36
oh
08:36
you mean ssh....
08:36
<maslak>
alkisg : it hapens only on low-budget and weak hardware, when I use thin clent with 1Gb of ram, and good graphic card everythink owrk fine
08:36
<alkisg>
(04:42:08 μμ) alkisg: Have you tried with LDM_DIRECTX=True?
08:36
<maslak>
alkisg : yes, didn't help...
08:36
<rickogden>
Gadi, yeah the ssh
08:36
<alkisg>
maslak: maybe you didn't use it correctly, it should make a huge difference
08:36
<rickogden>
it says "Authentication failed"
08:37
<Gadi>
rickogden: ok, you ran it from a shell on the thin client, right (not in a teerminal window in ldm)
08:38
<rickogden>
Gadi: yes, I enabled root and logged in as root on the thin client
08:38
<Gadi>
rickogden: seems there is an issue with you X authority
08:39
local devices uses X security to make sure other users cannot read your devices
08:39
<rickogden>
oh ok
08:39
<Gadi>
try logging out as that user
08:39
then, on the server, delete the user's ~/.Xauthority
08:39
if it exists
08:39
then log back in
08:40komunista has joined #ltsp
08:40
<maslak>
alkisg : it makes the difference - but as resuld of my observations - it still isn't enaugh to launch app... I see overload when I try to launch wine app - when I use: LDM_DIRECTX=True - my x session dies, and see ldm again - when i use LDM_DIRETX=False program won't launch... i see process is starting, but it dies after a while - same problem does not appear when I use VNC to Xsession on my server ... everything is fine ...
08:41
<rickogden>
Gadi: still the same error
08:41
<maslak>
komunista : you have polish looking nickname - are you polish ?
08:42
<alkisg>
maslak: what do you see in the user's ~/.xsession-errors when X dies?
08:42
<komunista>
no, but near :-)
08:42
<alkisg>
And, have you tried with a different graphics card?
08:44
<maslak>
alkisg : when i use nvidia and p4 3Ghz, 1Gb ram - works fine - but now i try to use as client hp t5530 (thin client) and tehre is no way to use other graphic card...
08:44
<Gadi>
rickogden: hmm... does this work: ssh -X -S /var/run/ldm_socket_vt7_192.168.0.254 192.168.0.254 "LTSPFS_NOAUTH=True /usr/sbin/ltspfsmounter /tmp add"
08:44
<alkisg>
maslak: what does that have? openchrome drivers?
08:44
<maslak>
I've asked about vnc protocol, becouse thats easiest solution ;)
08:45
<alkisg>
Sure you could use e.g. nx to access the server, but you'd need to write a screen script for that.
08:45
<maslak>
alkisg : you r asking about my present thinclient(hp?) ?
08:45
<alkisg>
Yes
08:45
<rickogden>
Gadi: no difference :(
08:46

<alkisg>
maslak: try disabling compiz
08:46
!compiz
08:46
<ltspbot>
alkisg: "compiz" :: if compiz is giving you problems, one way to disable it for all users is: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
08:46
<maslak>
compiz is removed form server
08:47
alkisg : it was my first move an it was remove --purge compiz* :)
08:47
<alkisg>
Heh :)
08:47
<Gadi>
rickogden: what distro are you running?
08:47
<rickogden>
Ubuntu Lucid
08:47
<Gadi>
rickogden: normal install?
08:47
<alkisg>
maslak: I've had X crashing with my openchrome client too but not on wine. It's still crashing but it's a little better now that I disabled compiz.
08:48
<rickogden>
hmm... I have spotted some scripts that someone else has put there that are being run on SSH to allow local mounting from thinstation... maybe they're interfering
08:48
Gadi: yes, pretty much
08:48
<Gadi>
ah, that might be it
08:49
<rickogden>
it's coming up with the messages: NXFOLDER is (null), NX_ROOT is (null), nxsession is (null)/(null)/session
08:49
<maslak>
alkisg : I can oly assume that, becouse i did'n chech yet - but I have thow ltsp servers now - old k12 onfedora (it uses VNC for display) and ubuntu lucid - both have some +/-...
08:50
<rickogden>
I'll look into that
08:50
<maslak>
... easiest way for me would be to run vnc to gdm directly (as in ol K12)
08:50
<Gadi>
maslak: I believe vnc has an option to run a single command, you can always run just the wine application in vnc
08:50komunista has quit IRC
08:51
<Gadi>
k12ltsp never used vnc for the thin clients
08:51
only to remote into the server
08:51
<maslak>
Gadi : that's not an option for me - users must have everything in one desktop, and I need it to be one gnome desktop...
08:52
Gadi : previous admin used it for every desktop, but i'm not familliar with fedora based sollutions, they are quite dofferent than debian based ...
08:52
<Gadi>
maslak: you can always make your own session and make it the default
08:52
so, make a session that runs vnc
08:53
LTSP simply runs: ssh -X .... /etc/X11/Xsession <session>
08:53
by default, <session> = gnome
08:53
but, you can create our own
08:54
<maslak>
as I understand how wine treats my dosplay now - I'll get the same problem with KDE, Gnome, and others if I use X as a direct display to it....
08:55
<Gadi>
correct
08:55
vnc only works because it runs an Xserver on the server
08:55
so it is independent of your client's xserver
08:56
<maslak>
so what i need is working vnc-server with different resolutions pointing to gdm, or other login manager ...
08:56
to get login into specific user server-side ...
08:57
<Gadi>
maybe
08:57
but, with ldm, you already have login
08:57
I dont see why gdm has to play at all
08:58
your <session> can simply be "run vncserver and vncviewer", or use Xephyr instead
08:58
and "run Xephyr"
09:27
<maslak>
any closer tips - or howto ?
09:28
and i'd like to keep system secure - what happens when I try to run miltiple vncserver instances with no password? may it be possible to just connect to: server:1,2,3 etc. and share/take over user's screen ?
09:39
<alkisg>
Why don't you try with XSERVER=vesa on those broken openchrome terminals first?
09:41litlebuda has joined #ltsp
09:41
<maslak>
on xserver=vesa seems to be more stable ;) but it still isn't goo enaugh (still overloading)
09:45secayford has joined #ltsp
09:45alexqwesa has quit IRC
09:46alexqwesa has joined #ltsp
09:57
<maslak>
alkisg : i've just tried x-server vesa with ldm_directx=false - waiting for over 10 mins to load app, still nothing - X feezing (freezed most the time, cannot click anything, mouse is moving) cppu usage 10%, ram usage 90/102, swap 25/25megs (a asume it uses built in flash memory as swap)
09:59
ifo i recieved from wine/codeveavers hq :) is that app may be using directx (which is using at90%) and that's what causing problems...
10:07
<alkisg>
maslak: swap is compcache, you can disable it by passing nocompcache as a kernel parameter
10:07
You'll see better performance with ldm_directx=false
10:07
What's eating the CPU? sshd?
10:08
It might also be a RAM problem, try disabling compcache and enabling NBD_SWAP=True in lts.conf
10:08
<maslak>
at first it was sshd, now is kswapd over 60%
10:08
<alkisg>
Right, so it's probably a low ram problem
10:08
In pxelinux.cfg/default, add nocompcache
10:08
<maslak>
could you give me more step-by step how to disable swap for single machine ?
10:08
<alkisg>
And in lts.conf, add NBD_SWAP=True
10:08
For a single machine you'd need a pxelinux/01-macaddress file
10:09
Copy pxelinux.cfg/default to 01-11-22-33-44-55-66
10:09
01- is a standard prefix for ethernet, the others are that PCs mac addresss
10:10
Then, on that file replace "quiet splash" with "nocompcache"
10:10
<maslak>
can I use hostname it it has tobe mac directly ?
10:10
<alkisg>
It has to be either a mac address or an IP
10:10
(ip in hex numbers)
10:10
<maslak>
;) no easy way ;P
10:12
<alkisg>
maslak: that wine app runs on the *server*, right? You didn't install it as a localapp and expect it to work with 128 RAM...
10:13
<maslak>
all apps are on server
10:13
there are no localapps
10:13
<alkisg>
OK, just checking :)
10:13
<maslak>
;]
10:14
yesterday tried witch localapps=false for sure :P
10:14japerry has joined #ltsp
10:15
<maslak>
just to be sure 1. copy default to 11:22... (just mac address) and add nocompcache at the end as new line ?
10:15hawkI has quit IRC
10:15
<alkisg>
Remember 01- at the start of the filename (better post the filename to be sure)
10:16
No, not as a new line. In the same line where quiet splash is. That makes it a kernel parameter.
10:16
To verify, when you boot the client, get a localxterm, and run the following commands:
10:16
!localxterm
10:16
<ltspbot>
alkisg: "localxterm" :: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
10:17
<alkisg>
lsmod | grep ram ==> you shouldn't see anything
10:17
ps ax | grep nbd ==> you should be seeing nbd-client /dev/nbd1, i.e. a swap file
10:17
And `free` should say that you have a 64Mb swap file.
10:18
<maslak>
i've changed my nbd swap filesize to 256mb - but i supose that's not a good idea over a 100mbit network ?
10:18
my config fiename is: 01-00:1b:78:91:44:7d
10:19
<alkisg>
No that's not right
10:20
01-00-1b-78-91-44-7d
10:20
<maslak>
;]
10:20
ok
10:21
<alkisg>
Well a 64Mb or at most a 128Mb swap file should be more than enough for an 128MB-RAM client. If it tries to use more, you've got a problem (memory leak? running apps locally instead of on the server?)
10:21
Also post the contents of that pxelinux.cfg/01-00-1b-78-91-44-7d file just to make sure.

10:35
if I want to see dmesg while booting just remove "splash" ?
10:36
<alkisg>
And quiet.
10:36
Any progress with that and with NBD_SWAP=True?
10:37
<maslak>
rebooting client - i saw in dmesg - nbd0 - unknown partition table....
10:37
<alkisg>
That's not a problem, it always says that
10:38dobber has quit IRC
10:39
<maslak>
not good... now my tc hanged itself ...
10:40
i was checking at htop performance stats... and while loading app... 100% cpu, 80% ram, and 13/256mb swap
10:41komunista has joined #ltsp
10:41
<alkisg>
What was using the cpu?
10:41
<maslak>
ssh tunnel
10:42
<alkisg>
Right, LDM_DIRECTX=True will solve that.
10:43
(you can specify it per client)
10:44dobber has joined #ltsp
10:44dobber_ has joined #ltsp
10:45
<maslak>
changed the swap settings to defaults, now it made 64mb swap, 90% mem usage by X, 90% cpu by ssh ... XSERVER=vesa
10:46
tc freezed after reaching 100% of swap ....
10:46
<alkisg>
It shouldn't use that much ram locally
10:46
So if you run it on an nvidia client, how much ram does it use to get up and running?
10:47
<maslak>
give me a minute i'll check on different machine ..

just checked on a dell gx260 - 1GB Ram, i915 graphics card
11:01
max ram usage 50% for a while, cpu max 80%, but just durring the start when it is running 40Mb ram is used, cpu is jumping up to 20%
11:01
swap which it has ( i asume it is on local hdd) untouched
11:02
<alkisg>
So it got to use 512MB of RAM locally? That's definately a problem
11:03
Did you manage to see which process was using that ram?
11:03
<maslak>
X
11:04
but there is another problem my thin clients are going to be: hp t5350
11:04
one big problem 128mb ram, shared with wideo memory
11:05
everything is embeded
11:05
(onboard)
11:05
cheap, energy and noise effective ;)
11:06
olny problem is that nasty wine... which ruins my whole ltsp idea ...
11:06
<alkisg>
Try the X_RAMPREC lts.conf directive, maybe it'll help. I guess wine is trying to use a lot of memory for pixmaps...
11:07
Anyway, bbl, good luck

<maslak>
x_ramperc set to 80 kills wine ;)
11:09
is there any possibility to set video memory size ?
11:09
maybe this will help...
11:10
or how to check memory of video used at now

I hear that
12:44
alkisg: I am getting ready to do a presentation at a Law School conference about using LTSP in their labs.. it worked well for me last summer.. and everyone in here was a great help...
12:44
I thought about doing an install during my presentation to show how easy the basic config is.. but I can't get the Ubuntu ltsp server installed in less than 45 mins.. any ideas?
12:46
<alkisg>
Why not? Does it need internet access?
12:46
I think it should be doable in about 30 mins...
12:46
(depending on the hardware, of course)
12:47
If you're trying with a CD, try with a usb stick instead.
12:47
<bieb>
no.. I did the install yesterday of 9.10 and it took over an hour and a half
12:48Lns has joined #ltsp

<bieb>
alkisg: you have link to a good how to .. to build the USB stick? I will have to see if this PC's BIOS even boots from USB.. its an old Dell Optiplex GX 260
12:50
<alkisg>
Ah, if it's old maybe you could show the edubuntu live ltsp instead
12:50
To create a usb stick you just go to system > settings > usb creator or something like that (I don't have english menus)
12:51
<bieb>
ok.. so there is a live Cd for edubuntu?
12:52
<alkisg>
Yup, the 10.04 live dvd which also contains a live ltsp script.
12:52
<bieb>
cool.. I will look at that also
12:58
alkisg: how much different is 10.04 than 9.10??

that is odd

No, just timing. :)

maybe show the Ubuntu boot screen.. then.. remove CD and boot

Anyone use pam_mount in here?
14:40
<vmlintu>
Ghidorah: I used to
14:40
<Ghidorah>
do you use something else now?
14:40
<vmlintu>
autofs
14:41
<Ghidorah>
any reason for the switch?
14:41
<vmlintu>
The setup is now different, we used to need cifs mounts before, but now it's all nfs4
14:43
pam_mount itself worked quite nicely after getting it setup
14:43
<Ghidorah>
I'm having a heck of a time with it
14:43
the %(DOMAIN_USER) is making me pull my hair out.
14:44
<vmlintu>
Setting it up was not easy, I remember
14:44
<Ghidorah>
my problem is the %(DOMAIN_USER) returns the username of the user
14:44
but with it's proper case so SSmith01
14:44
while likewise-open creates the home dir with it all in lower case
14:45
%(USER) returns domain\user
14:45vagrantc has quit IRC
14:47
<vmlintu>
I didn't have any mixed case usernames if I remember correctly
14:47
what kind of mount command do you have in pam_mount.conf?
14:49
<Ghidorah>
<volume options="dmask=0700" sgrp="student" user="*" fstype="cifs" server="server" path="home/student/%(DOMAIN_USER)" mountpoint="/home/Domain/%(DOMAIN_USER)/USer_Drive" />
14:50
<vmlintu>
hmm, looks like the configuration file format has changed quite a bit since I last used it
14:50
My notes have a flat file structure with no xml..
14:51vagrantc has joined #ltsp
14:51
<Ghidorah>
yeah it now uses a xml file
14:52
<vmlintu>
the old format let you specify the mount command so you could have written a script to wrap the actual mount command and lowercase the username..
14:55
<Ghidorah>
that is what I'm looking to do
14:56
I just don't know if i can.

i use that a bit, Ghidorah
15:23
<Ghidorah>
what versions are you running?
15:23
<abeehc>
very fresh onesec
15:24
i've struggled with the user matching but my conifig uses ~
15:24
like this mountpoint="~/Shares/Data_on_file_server" />
15:25
<Ghidorah>
ahh I see
15:25
<abeehc>
er i've struggled with doing specific mounts based on a secondary domain group
15:25
<Ghidorah>
how do you match the mount
15:25
mean the share on the server
15:25
<abeehc>
<volume user="*" options="username=%(USER),sec=krb5,user=%(USER),domain=MYDOMAIN,guest" fstype="cifs" server="server.corp.com" path="data" mountpoint="~/Shares/Data_on_file_server" />
15:26
<Ghidorah>
does %(USER) return the domain\user for you?
15:26
<abeehc>
I'm pretty certain user only returns the username and in my experience to this point it's always lowercase
15:27
<Ghidorah>
are you on Ubuntu 10.04?
15:27
<abeehc>
though I don't use it in the mountpoint so i'm not sure
15:27
9.04 and 9.10 ive' used this on
15:27
<Ghidorah>
:-/
15:27
yeah it worked like a champ in 9.04 and 9.10
15:27
<abeehc>
man i don't know for me champ isn't the right word
15:28
but i'm sad to hear it doesn't work perfect in 10.04
15:28
<Ghidorah>
I was able to get everything working as expected on karmic
15:28
<Gadi>
Ghidorah: maybe you should play with the likewise settings instead
15:28
ie. have it always return lowercase username
15:28
<abeehc>
yeah ghadi might be on to something there
15:28
<Ghidorah>
likewise renders the usernames to always lower case
15:29
the problem is %(DOMAIN_USER) in pam_mount does not
15:29
<Gadi>
is %(USER) always in lowercase?
15:29
<Ghidorah>
yes but it is in domain\user format now
15:29
<Gadi>
do you have more than 1 domain?
15:29
<Ghidorah>
no
15:30
<Gadi>
then set likewise to use default domain
15:30
<Ghidorah>
I do
15:30
rather I have.
15:30
but when you login
15:30
<Gadi>
ah, then you should never get domain\user as the username
15:31
<abeehc>
http://davidmburke.com/2010/03/30/linux-and-active-directory/
15:31
* in 10.04 %(USER) gives you the domain/user. If you just want the user use %(DOMAIN_USER)
15:31
<Ghidorah>
aye
15:31* PMantis thinks that seems backward. LOL
15:32
<abeehc>
yeah i can't say that is for sure accurate
15:32
<Gadi>
there was a version of likewise-open shipped with Lucid that was broken wrt default domain
15:32
I think you need the one from the ppa to work properly
15:32
lemme find a link
15:33
<PMantis>
abeehc, I have no experience with likewise, but it just seems backward. DOMAIN_USER for just user, but USER for domain\user
15:33
<Ghidorah>
I'm using the ppa

I have ltsp up and running on ubuntu 10.04. I want to install sabayon. Do I install it in the chroot or the server root?
15:36
<johnny>
server root
15:36
unless you're using fat clients
15:36
<danno>
Yes - I'm using fat clients
15:37
<johnny>
then you'd have to install in 2 places
15:38
one on the fat client chroot
15:38
and then on aother machine where you create the profile
15:38
then you'd copy the created profile to your chroot
15:39
<danno>
Thanks johnny I 'll do that now.
15:40
<PMantis>
sabayon? Isn't that a distro?
15:42
<abeehc>
they share the name i think http://live.gnome.org/Sabayon/
15:50komunista has quit IRC
15:51

yes.. they share a name .

gnome sabayon should probably be renamed to gnome user profile tool or something

the menu option is already called "User Profiles"

I've been reading the 2009 thread at http://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg37283.html - regarding localapp printing from firefox...was this ever resolved? I'm having the exact same issue with seeing the CUPS printer from a localapp firefox, but the "print" button is grayed out and I can't actually print anything..

<maslak>
hello
17:45
is there a possibility to run some shell commands on ltsp client defined at lts.conf ?
17:46
for eg. i'd like to run some client-dependent (ip/hostname) scripts defined previously in chroot enviroment ...
17:47
<alkisg>
!lts.conf
17:47
<ltspbot>
alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
17:47
<alkisg>
maslak: see RCFILE_01 there ^^^
17:47
<maslak>
;]
17:50
i don't think rcfile is what I need ... eventually i'd have to create many files containing various combinations ...
17:50
i'd like to run command1 & command2 & command3
17:51
as root, invisible to user
17:51
but i also can use rcfile_0=command0,rcfile_1=command1 etc ...
17:52
that's some solution but i'm hoping to get sth more elastic ...
17:52
<alkisg>
Can you be more specific? I can't imageine why rcfile isn't what you want
17:52
You'd like to be able to modify the commands without updating the chroot?
17:53
<maslak>
i'm going to use my thnclients as mjpeg streaming servers for usb cameras connected to them
17:53
<alkisg>
Then having a shell there would be nicer, than having just an rcfile
17:53
<maslak>
sample command: mjpg_streamer -i "input_uvc.so -d /dev/video1 --yuv -r 320x240 --fps 5" -o "output_http.so -p 8081" -b
17:54
<alkisg>
If the command is always the same, then an rcfile would also do the work
17:54
<maslak>
problem is that same for eg. video0 can be diferent model with different parameters ...
17:55
and according to port i connect camera, and it's order - devices will change ...
17:56
<alkisg>
Wouldn't it be better then to have a script autodetect the device number?
17:56
<maslak>
now i'm testing zoneminder + cheap usb webcams + cheap terminals, to create low-cost but effective mnitoring sollution in my company ...
17:57
<alkisg>
You could probably even have an udev rule to make them always have a specific name
17:57
<maslak>
sorting them by hrdware id number ? and giving always same /dev/videoX ....
17:57
?
17:58
<alkisg>
Something like that, yes...
17:59
<maslak>
looks like something to learn ;) but not enaugh time for now to do this...
17:59
;]
17:59
and what happens when I get 2,3 or more identical webcams ... ;)
18:01
<alkisg>
Whatever you want to happen, I imagine that udev rules are flexible enough to do what you want with them
18:02
Or you could just autodetect the devices names, whatever those are..

tftp-hpa -- netstat shows as running, but all file transfers time out. The only thing I changed in /etc/default/tftpd-hpa was RUN_DAEMON="no" to RUN_DAEMON="yes" Anyone have any ideas?
22:36peter_tm has left #ltsp
22:38
<johnny>
kill it and try again?
22:38
<slidesinger>
Tried that, several times.
22:43
<johnny>
is this ubuntu?
22:43
if so.. please turn off RUN_DAEMON
22:44
perhaps even in debian, i'm not quite sure if they use openbsd-inetd for ltsp
22:44
like ubuntu does
22:44
<slidesinger>
johnny: Is debian, and yes the use openbsd-inetd.
22:44
<johnny>
then you're trying to start 2 daemons on one port, that won't work
22:44
as inetd is already going to want to start tftp
22:45
if you start the the tftp daemon via /etc/init.d/tftp-hpa, it's gonna conflict
22:47
<slidesinger>
Trying that now.
22:49
<johnny>
why did you initially want to change RUN_DAEMON?
22:49
was something else not workign?
22:49
<slidesinger>
Read that in docs for debian/ubuntu
22:49
<johnny>
but it was working before?
22:50
<slidesinger>
Don't know.
22:50
I did not try until after making the change.
22:50
<johnny>
ah, well make sure /etc/inetd.conf does start a tftp server then
22:51* johnny has never used ltsp on debian
22:51
<johnny>
maybe you should do daemon mode, i just know how ubuntu does it with openbsd-inetd
22:51
otherwise there might actually be a tftp problem
22:55
<slidesinger>
/etc/init.d/tftpd-hpa start error: tftpd-hpa disabled in /etc/default/tftpd-hpa
22:55
So that is not it.
23:01
<johnny>
you didn't answer my question
23:01
or rather
23:01
you didn't look in /etc/inetd.conf to see if it started tftp or not
23:05
<slidesinger>
Ah, yes I did. The line is: tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -l -s /var/lib/tftpboot
23:07
<johnny>
ok, so then you don't want to use /etc/init.d/tftpd-hpa, inetd will automatically start them for you
23:07
or should
23:08
<slidesinger>
OK, netstat -a | grep tftp will confirm that it is running?
23:09
<johnny>
no
23:09
it gets started on demand
23:09
<slidesinger>
How can I confirm that it is running?
23:09
<johnny>
try booting a client :)
23:09
or use a tftp client on your terminal
23:10
<slidesinger>
OK, I'll try the tftp client as the client is not picking anything up.
23:13
tftp 192.168.1.103
23:13
tftp> get test
23:13
Transfer timed out.
23:18
<johnny>
is there that file?
23:19
also, check your daemon logs, i wonder if there is some other problem
23:20
<slidesinger>
Yes, there is such a file.
23:21
Log:

uhmm.. ps ax | grep tftp ?
23:23

So not running?

23:26
<johnny>
do you have more than 1 entry in /etc/inetd.conf for tftp? do you use dnsmasq? any other tftp programs in /etc/init.d ?
23:27
<slidesinger>
No, no, and no.
