| 00:38 | <ME_nerd> Hi all. I am looking for a little help to resolve a login problem. The problem is that i can login from the ldm greeter, but then the session dies and the ldm greeter comes up again. I checked the logs on the thing client and found a line "Warning: No xauth data; using fake authentication data for X11 forwarding." then "connection to --server-- closed by remote host"
| |
| 00:39 | <sbalneav> Under what conditions doe the session die?
| |
| 00:39 | <ME_nerd> uh.... all of them
| |
| 00:39 | i have yet to be able to login
| |
| 00:39 | <sbalneav> "The problem is that i can login from the ldm greeter,"
| |
| 00:39 | <ME_nerd> oh
| |
| 00:40 | hahah
| |
| 00:40 | <sbalneav> So, you can or can't get logged in?
| |
| 00:40 | <ME_nerd> well the server accepts my login and password
| |
| 00:40 | but then it quickly kills the session before I actually see a desktop
| |
| 00:40 | <sbalneav> ok, first off:
| |
| 00:40 | !version
| |
| 00:41 | <ltspbot> sbalneav: The current (running) version of this Supybot is 0.83.3. The newest version available online is 0.83.3.
| |
| 00:41 | <ME_nerd> I also can't ssh into the server from the thin client
| |
| 00:41 | <sbalneav> meh
| |
| 00:41 | hanthana has quit IRC | |
| 00:41 | <ME_nerd> hmmm
| |
| 00:41 | <sbalneav> What version of host OS, and LTSP are you running?
| |
| 00:41 | <ME_nerd> ubuntu
| |
| 00:41 | sorry
| |
| 00:41 | <sbalneav> ubuntu.... what? Hardy?
| |
| 00:41 | <ME_nerd> i mean ubuntu 8.10, and i will grab the version of ltsp
| |
| 00:42 | <sbalneav> So, intrepid?
| |
| 00:42 | ok
| |
| 00:43 | So, when you say: "I also can't ssh into the server from the thin client", have you set a root password on the thin client, and you're ctrl-alt-f1'ing to a text login screen, and logging in from there?
| |
| 00:43 | <ME_nerd> yes, i did enable the root access on the terminal, and did ctrl-alt-f1
| |
| 00:44 | and I can't seem to find the version of ltsp other than ltsp5
| |
| 00:44 | oh yeah, sorry, you helped me last night.... so i forgot to mention it today
| |
| 00:44 | <sbalneav> Your server's at 192.168.0.254?
| |
| 00:45 | * highvoltage does 'ltsp-localapps xterm' these days | |
| 00:45 | <ME_nerd> i am serving dhcp and tftp off of one server and x off of anotehr
| |
| 00:45 | no, it is at 192.168.1.141 for the x server
| |
| 00:45 | and 192.168.1.11 for the dhcp server
| |
| 00:46 | <sbalneav> What does your lts.conf file look like?
| |
| 00:46 | Can you paste it to the pastebot?
| |
| 00:46 | !pastebot
| |
| 00:46 | <ltspbot> sbalneav: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
| |
| 00:47 | <ME_nerd> just simple right now..... [default] server = 192.168.1.141
| |
| 00:47 | but i will grab the actual file
| |
| 00:48 | <ltsppbot> "ME_nerd" pasted "lts.conf" (5 lines) at http://pastebot.ltsp.org/106
| |
| 00:50 | <sbalneav> Ditch the SCREEN_07, since it's the default, and try adding back in the LDM_DIRECTX=True
| |
| 00:50 | <ME_nerd> ok, i was just doing that now
| |
| 00:53 | ok, the same thing happened. to ldm
| |
| 00:53 | this lts.conf should be on the boot server correct?
| |
| 00:53 | <sbalneav> Yes.
| |
| 00:54 | Two things I'd like to see.
| |
| 00:54 | 1) the .xsession-errors file of the user you're trying to log in as.
| |
| 00:54 | 2) any errors from the ldm.log file on the thin client.
| |
| 00:55 | <ME_nerd> i just checked the ldm.log
| |
| 00:55 | that came up with the same errors about xauth
| |
| 00:55 | and the remote host killing the connection
| |
| 00:55 | but it did show that ssh login was successful
| |
| 00:56 | to clarify: early on in the log is says that ssh was successful, i assume because it didn't do any ssh? then later in the log i get the orginal errors
| |
| 00:57 | <sbalneav> Why don't you copy the log to the server, and paste it in the pastebot?
| |
| 00:57 | <ME_nerd> i will try to ssh in from the client, but i had no luck last time
| |
| 00:58 | here is .xsession though
| |
| 00:58 | <ltsppbot> "ME_nerd" pasted "xsession-errors" (46 lines) at http://pastebot.ltsp.org/107
| |
| 00:59 | <sbalneav> xauth: (argv):1: bad "add" command line
| |
| 01:00 | that's going to be your problem right there.
| |
| 01:01 | <ME_nerd> is that pretty obvious? should i google it :-)
| |
| 01:02 | <sbalneav> the ldm.log file will help to narrow it down
| |
| 01:02 | <ME_nerd> yup, i have that (i guess i forgot what my real user name was when i tried to log in before)
| |
| 01:03 | <ltsppbot> "ME_nerd" pasted "ldm.log" (46 lines) at http://pastebot.ltsp.org/108
| |
| 01:04 | <sbalneav> Have you modified this server's sshd config file?
| |
| 01:04 | <ME_nerd> no
| |
| 01:04 | <sbalneav> By maybe disallowing X11 forwarding?
| |
| 01:04 | <ME_nerd> no, but let me take a look at it
| |
| 01:05 | "X11Forwarding Yes"
| |
| 01:06 | <sbalneav> ok
| |
| 01:06 | hm, well not sure what's going on, but something's blocking your X forwarding.
| |
| 01:06 | lets try this, as a hack
| |
| 01:06 | <ME_nerd> ok
| |
| 01:07 | <sbalneav> in your lts.conf file, add X_ARGS=-ac
| |
| 01:09 | reboot and try that
| |
| 01:10 | <ME_nerd> ok
| |
| 01:10 | same visual problems
| |
| 01:10 | but i didn't look at ldm.log yet
| |
| 01:11 | ldm.log looks the same but i can post it if you want
| |
| 01:14 | yes, ldm.log is exactly the same except for the magic cookie line
| |
| 01:14 | <sbalneav> Well, either the xauth file isn't being created properly in the first place, or it's not adding the xauth data to the server.
| |
| 01:15 | <ME_nerd> ok, well maybe i should scrap it and try again.
| |
| 01:16 | i am just trying to get it up and running for a first time to try it out
| |
| 01:16 | but the x server is my desktop..... so maybe that just makes things more complicated
| |
| 01:16 | <sbalneav> After it's logged in, can you see the ssh command line?
| |
| 01:16 | <ME_nerd> hmmmm
| |
| 01:17 | i can in fact log into the server through ssh from the terminal
| |
| 01:17 | but that is independent of logging in through ldm
| |
| 01:18 | (also i get the same problem with startx using gdm or xdm)
| |
| 01:18 | <sbalneav> If it were me, I'd say something's misconfigured somewhere.
| |
| 01:18 | <ME_nerd> but not when i do X -query from another system
| |
| 01:19 | probably something on the boot server which is feeding the pxe image to terminal?
| |
| 01:20 | or do you think it is misconfigured on the x server
| |
| 01:20 | <sbalneav> Not sure, doesn't seem to make sense.
| |
| 01:20 | <ME_nerd> hahah
| |
| 01:21 | ok well thanks for all the help today, and thanks for pointing me in the right direction last night
| |
| 01:21 | <sbalneav> the core of the problem is that the ssh isn't forwarding proper X auth data, but rather faking it.
| |
| 01:21 | <ME_nerd> hmmm
| |
| 01:22 | ok, well i will poke around on the boot server, but if i don't find anything i will restart from fresh
| |
| 01:22 | <sbalneav> ok, cool
| |
| 01:22 | I'll be around
| |
| 01:23 | <ME_nerd> alright, have a nice night/day

| |
| 07:06 | Is there more to do ?

| 11:59 | <dberkholz> johnny: that sounds useful. got a link or bug #?
| |
| 12:03 | <Appiah> johnny and why is that?
| |
| 12:04 | USE_LOCAL_SWAP should use the thin client as SWAP right?
| |
| 12:05 | <johnny> Appiah, that was the 2nd part. i mean the first part
| |
| 12:05 | dberkholz, http://bugs.gentoo.org/show_bug.cgi?id=186652
| |
| 12:06 | <Appiah> well I opened up a terminal with ltsp-localapp, tried launching firefox
| |
| 12:07 | firefox dies beacuse it runs out of memory
| |
| 12:07 | <johnny> local swap will take forever
| |
| 12:07 | if you're relying on that, i wouldn't use local apps
| |
| 12:07 | <Appiah> I do cat /proc/meminfo and see there is very little mem
| |
| 12:07 | <johnny> it'll be faster over the network
| |
| 12:07 | <Appiah> oki, should i increase the NBD instead?
| |
| 12:08 | <johnny> are you using nbd swap?
| |
| 12:08 | <Appiah> I'm using Ubuntu 8.10 (installed with alternate) If I'm correct NBD is the method by defaylt
| |
| 12:08 | default*
| |
| 12:09 | <johnny> nbd is default, but not nbd swap
| |
| 12:09 | two seperate things
| |
| 12:09 | <Appiah> aha
| |
| 12:09 | <johnny> i think you'er still not going to be happy with the performance
| |
| 12:10 | <Appiah> I thought using local app for Firefox was working great?
| |
| 12:10 | <johnny> if you have 256mb or more locally
| |
| 12:10 | of ram
| |
| 12:10 | <Appiah> hmm
| |
| 12:10 | <johnny> anything less and you won't be happy from my understanding
| |
| 12:10 | faster to just run it as normal
| |
| 12:11 | <Appiah> well then there is the problem with to many users
| |
| 12:11 | would be nice to get the load of the server
| |
| 12:11 | some*
| |
| 12:11 | <johnny> get better clients..
| |
| 12:11 | increase their ram
| |
| 12:11 | <Appiah> ;)
| |
| 12:16 | johnny got any way to see that USE_LOCAL_SWAP is actully on?
| |
| 12:22 | <johnny> go to a virtual terminal and type cat /proc/swaps
| |
| 12:22 | ctrl + alt + f2
| |
| 12:23 | altho. you'd need SCREEN_02=shell
| |
| 12:23 | in your config
| |
| 12:23 | lts.conf
| |
| 12:24 | <Appiah> thanks

| 14:27 | <johnny> wtf is up with canonical upselling in my motd
| |
| 14:27 | please use our new landscape service
| |
| 14:28 | <loather> canonical gotta eat too
| |
| 14:28 | (not that i appreciate advertizements of any kind being shoved in my face either)
| |
| 14:29 | <jammcq> fortunately, motd can easily be edited to suit your needs
| |
| 14:32 | <rjune_> jammcq !
| |
| 14:32 | <jammcq> hey rjune_
| |
| 14:33 | <rjune_> johnny: You can always change it
| |
| 14:38 | <loather> yeah, a simple echo >/etc/motd fixes that :)
| |
| 14:39 | <johnny> i dont think so
| |
| 14:39 | it's being generated
| |
| 14:40 | ogra has quit IRC | |
| 14:40 | <johnny> so it'll just get regenerated again
| |
| 14:40 | i need to figure out where it comes from and disable it
| |
| 14:40 | ogra has joined #ltsp | |
| 14:40 | <loather> yeah. that'd be anoying if it kept getting regenerated
| |
| 14:40 | <johnny> it does
| |
| 14:40 | the information is up to date
| |
| 14:41 | or maybe it looks for certain contents before doing so?
| |
| 14:41 | <loather> i'd be annoyed if i actually had a useful MOTD and that crap stomped it
| |
| 14:41 | <johnny> we'll see if it comes back
| |
| 14:41 | i dropped the contents
| |
| 14:43 | <loather> johnny: aptitude remove landscape-sysinfo
| |
| 14:43 | <johnny> what are the benefits of aptitude over apt-get anyways?
| |
| 14:44 | i've never had to use it
| |
| 14:44 | <loather> different tool same job
| |
| 14:45 | didn't know if ubuntu dropped apt-get and friends
| |
| 14:45 | <johnny> no way
| |
| 14:45 | why would they do that?
| |
| 14:46 | <loather> dunno. aptitude is being touted as the end-all, but i've never seen anything it can do better than apt-get/apt-cache/etc.
| |
| 14:47 | <johnny> aptitude existed for debian first iirc?
| |
| 14:47 | <loather> yup
| |
| 14:47 | <johnny> and they still use apt-get :)
| |
| 14:47 | <loather> i think they shipped it first with sarge
| |
| 14:57 | <johnny> nubae, are you sure you tested your fatclient scripts??
| |
| 14:57 | it generates an almost completely invalid cron script
| |
| 14:57 | the shebang line isn't even in the first line
| |
| 14:57 | err first column
| |
| 14:57 | you need to remove all the spacing if you want to do heredco
| |
| 14:57 | heredoc
| |
| 14:58 | plus.. i think i chose the wrong user..

| |
| 18:47 | YEEEEAAAAAAAHHHHHHHHHHH
| |
| 19:12 | loather: At one time, aptitude was supposed to have better depenency resolution than apd-get
| |
| 19:13 | but everyone was used to apt-get, so in the end, IIRC, they simply moved the better tree spanning algorithms from aptitude back to apt-get
| |
| 19:14 | So, other than the fact that aptitude combines both apt-cache, apt-get, and has a text based menu front end to apt, there's not much difference.

| |
| 20:59 | <warren> hmm, that is so distant in the past it doesn't work as a joke anymore.
| |
| 20:59 | <johnny> i don't really need alot of help.. just newer software than ubuntu :)
| |
| 21:00 | <petre> ah, The Great Red Hat Schism
| |
| 21:00 | <johnny> warren, ?
| |
| 21:00 | <petre> yeah, it's pretty old any more
| |
| 21:01 | <johnny> all i want.. is a distro with newer software than ubuntu
| |
| 21:01 | or gentoo for that matter
| |
| 21:02 | <petre> warren, notice the package name is changed; is that okay? I rather change it sooner rather than later
| |
