[09:51] <Nazgul2> hi
[09:52] <alkisg> Hello
[09:57] <Nazgul2> i would like to know somethin aboutn edubuntu
[09:57] <Nazgul2> i heared it is good for terminal server usage
[10:02] <alkisg> It is, combined with LTSP
[10:03] <alkisg> https://help.ubuntu.com/community/UbuntuLTSP
[10:15] <nubae> alkisg, u there?
[10:15] <alkisg> Hey nubae, long time no see... what's up?
[10:16] <nubae> hey, indeed... back to the world of ltsp... have to do a hardy upgrade... better said, have done most of a hardy upgrade, but getting some weird problems with the client
[10:16] <nubae> after doing a ltsp-update-sshkeys and image, get no response from server
[10:16] <nubae> when any user tries to login from a thin client
[10:16] <alkisg> And if he tries to login from SCREEN_02=shell?
[10:17] <nubae> I shall try that... but from the command prompt error I get is unknown userid
[10:18] <nubae> the /home was on another disk, though don't see how that could interfere
[10:18] <alkisg> SCREEN_07=ldm, SCREEN_02=shell, ssh user@server
[10:18] <alkisg> Change "user", leave "server" exactly as it is, don't use the server ip or hostname
[10:18] <nubae> I'm not at the school at the moment, but I'll see if I can ssh in, thought doubt it
[10:19] <nubae> ok
[17:37] <nubae1> alkisg: u around?
[17:38] <alkisg> Hi nubae1
[17:38] <nubae1> I'm at the school now... tried sshing in from thin client
[17:38] <nubae1> getting connect host server port 22: connection refused
[17:39] <nubae1> I'm figuring this might be because I had squi/dansguardian/shorewall running on hardy
[17:39] <nubae1> but not on lucid
[17:39] <nubae1> that make sense?
[17:49] <alkisg> nubae1: no idea, I've never used dansguardian or shorewall. But squid shouldn't be able to affect your system if it's not installed.
[17:49] <alkisg> Are you sure that the "server" has the correct IP there?
[17:51] <nubae1> weird thing is if I do /cat/resolv.conf on the thin client
[17:52] <nubae1> I don't get the same details as in /opt/ltsp/i386/etc/resolv.conf
[17:52] <alkisg> Those come from the dhcp server
[17:52] <nubae1> it gives me change this for your server instead
[17:52] <nubae1> ah
[17:52] <nubae1> right
[17:52] <nubae1> makes sense
[17:53] <nubae1> so it ignores /etc/resolv.conf?
[17:53] <alkisg> It overrides it, if the dhcp send dns info
[17:53] <alkisg> *or overwrites, same meaning :D
[17:54] <nubae1> hmmm, ok... well, then I'm at square 1, I've installed squid, dans, shorewall again
[17:54] <nubae1> and everything is fine on server
[17:54] <nubae1> just no connection from thin client
[17:54] <alkisg> nubae1: can you ssh to the server from other pcs?
[17:54] <nubae1> nope
[17:55] <nubae1> which means must be sshd_conf?
[17:55] <alkisg> Check the logs to see if some program is blocking the connection
[17:55] <alkisg> sshd, iptables, firewalls, you name it
[17:55] <nubae1> logs show nothing
[17:55] <alkisg> Can you ssh to localhost on the server?
[17:56] <nubae1> permission denied
[17:56] <alkisg> And still no logs?
[17:56] <alkisg> (from the system > settings > logs utility)
[17:56] <nubae1> nope nothing in logs... why would I get that: permission denied (public key)
[17:57] <alkisg> Messed up sshd_config?
[17:57] <nubae1> most likely
[17:57] <alkisg> But still, a log entry should be filed
[17:57] <nubae1> checking
[17:57] <nubae1> nothing under messages
[17:57] <nubae1> but checking other
[17:57] <alkisg> Run the log utility,
[17:57] <alkisg> try ssh localhost,
[17:57] <alkisg> and see if any of them goes "bold"
[17:58] <alkisg> That means it has new entries
[18:01] <nubae1> can u paste me a virgin sshd_conf?
[18:02] <nubae1> I get the nbd messages in logs, but just connect and disconnect
[18:03] <nubae1> I'll copy it from a backup too, but must be my sshd_conf is messed up
[18:10] <nubae1> I've got the external server set under listen address in sshd_conf on server, does that make sense
[18:10] <nubae1> ?
[18:11] <nubae1> I've been away too long from ltsp
[18:13] <nubae1> getting internet from normal clients via nat
[18:13] <nubae1> so that isnt it
[18:14] <nubae1> has to be ssh then right?
[18:19] <nubae1> damn, cant get ssh localhost to work on server, connection refused, but no message about keys anymore
[18:19] <nubae1> and nothing in the log files
[18:20] <alkisg> nubae1: /etc/ssh/sshd_config: http://ltsp.pastebin.com/Mv3QDcSS
[18:20] <alkisg> Then try again ssh localhost
[18:25] <nubae1> ok all working now
[18:25] <nubae1> at least ssh localhost
[18:27] <nubae1> ssh fixed now from thin clients too
[18:28] <nubae1> but still no ability to login to Xç
[18:28] <nubae1> still, feel it getting close :-)
[18:29] <alkisg> From SCREEN_02, "ssh user@server"
[18:30] <nubae1> yep
[18:30] <nubae1> no problem
[18:30] <alkisg> Does that work with no warnings _at all_ ?
[18:30] <nubae1> yep
[18:30] <alkisg> And then when you switch to vt7 and try to login with the same user, what do you get?
[18:30] <nubae1> nothing in log files either
[18:31] <nubae1> weird, now works
[18:31] <nubae1> thanks alkisg
[18:31] <alkisg> You're welcome, but do try to reboot the client and check again if it works :)
[18:32] <nubae1> checking with other usernames and such
[18:32] <nubae1> what should permissions be username.username?
[18:32] <nubae1> or can it be username.users
[18:33] <alkisg> Permissions where?
[18:33] <nubae1> for /home
[18:34] <nubae1> for /home/username
[18:34] <alkisg> It's usually user:user, but if you have a specific reason to, you can also use user:group
[18:35] <nubae1> ok, well all seems to be well now
[18:35] <nubae1> just takes for ever to login
[18:36] <alkisg> Try with a new user, and time the *second* time it logs in
[18:36] <alkisg> It should be less than 10-20 secs...
[18:38] <nubae1> sysadmin can login
[18:38] <nubae1> seems normal users cannot
[18:38] <nubae1> trying with a new user
[18:39] <alkisg> (create it with users-admin, not with adduser...)
[18:39] <nubae1> oh ok
[18:41] <nubae1> yeah new users cant log in
[18:42] <nubae1> failed due to unknown userid (0)
[18:42] <nubae1> get that in terminal just after no response
[18:43] <alkisg> Ignore that, that's pulseaudio
[18:43] <alkisg> Do you get an entry in the server /var/log/auth.log for that user?
[18:44] <nubae1> weird weird
[18:44] <nubae1> on 192.168.0.2 works for all users
[18:44] <nubae1> other ips doesnt work
[18:44] <nubae1> thinnk its time for server restart
[18:45] <alkisg> ltsp-update-sshkeys && ltsp-update-image
[18:45] <alkisg> I don't think server restarting will help for that
[18:47] <nubae1> well graphics on server crashed
[18:47] <nubae1> so needed a restart anyway
[18:55] <nubae1> ok think its all working now.... thanks... a lot
