<vsuojanen>
was there a package in trusty that would mount localdev usb for xfreerdp ?
15:03vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
15:06
<vsuojanen>
if i understood right ldm gets usb mounted with the ltspfs. is anyone using it also in chroot with xfreerdp?
15:07
<vagrantc>
yes, there are recent posts to ltsp-discuss@lists.sourceforge.net
15:07
i haven't used it myself, but there are several ways to make it work
15:13
<vsuojanen>
what alternative ways you have seen for the mount? if there is ltspfsd or similar running i'm interested
15:15
<vagrantc>
i think installing both ltspfs and ltspfsd in the chroot is the classic method.
15:16
which should automatically mount /media/root/
15:16
and then telling xfreerdp/rdesktop to show /media/root as a drive
15:17
in lts.conf: RDP_OPTIONS=-r disk:Drives=/media/root
15:17
someone also reported using the "usbmount" package.
15:17
<vsuojanen>
vagrantc: thanks. i look them. i tried ltspfs in google but it didn't hit anything i could benefit
15:19
i saw that usbmount but didn't have time yet to experiment it
15:20
thank you mucho.

Howdy. ANyone know why I would be getting a "failed login from root" in ssh log when trying to open ldm session?
21:47
getting the message in var/log/secure
21:48
It sucessfullly authenticates the user, but then fails a connection from root, then disconeccts the user

scotty_: you're trying to log in as root?
21:59
scotty_: or you're trying to log in as the user and it's issuing an error message "failed login from root" ?
21:59* vagrantc has deja-vu
22:06
<scotty_>
regualr user
22:07
getting the message in the secure log. Been beating my head on this for a few days now
22:07telex has left IRC (telex!teletype@freeshell.de, Remote host closed the connection)
22:07
<vagrantc>
scotty_: distro? version?
22:07
<scotty_>
using SL 6 x64, also tried centos 6 x64. Have done it last year a few times with no problems. Al single NIC boxes
22:08
using the dhcp from alternate server
22:08telex has joined IRC (telex!teletype@freeshell.de)
22:08
<scotty_>
next-server option
22:08
<vagrantc>
unfortunately, there is virtually no support for redhat derivatives... it hasn't been maintained for years.
22:09
<scotty_>
Noticed that. What is the best support distro for it these days? Ubuntu?
22:09* vagrantc is partial to debian
22:09
<vagrantc>
ubuntu has been lagging a bit as well :(
22:09
but at least there are ppa's of current LTSP for ubuntu
22:09
<scotty_>
just driving me crazy, as it works fien on a coupel I did just last year on SL.
22:10
Hmmm.. deb then is best suported these days?
22:10
<vagrantc>
possibly something changed in the way ssh master sockets are used in SL ?
22:10
i'm biased, being the one who maintains ltsp in debian. :)
22:11
<scotty_>
I'm not partial. If it works, that's good mby me :-)
22:11
<vagrantc>
Debian Jessie (8.0) releases on Saturday
22:11
<scotty_>
it includes support for ltsp then?
22:11
<vagrantc>
sure does
22:12
<scotty_>
That may be my route then.
22:12
Ahh, client just complted the build, let's see what it does this time
22:16
Wow, I haven't used irc for mabe 10-15 years. vagrant, you around here often? I may need some guidance if I have to go that route, appreciate your thoughts today
22:17
ok.. booting. got pxe.
22:17
got mount to nfs
22:18
pulseaudio errors, don't really care, this is for a business without sound
22:18
at login.. let's see
22:18
nope, back to login.
22:19
<vagrantc>
i'm around fairly often
22:20
<scotty_>
On ltsp box, in var/secure:
22:20
<vagrantc>
but feel free to ask the channel, there are plenty of other knowledgeable folks around
22:20
<scotty_>
Apr 22 18:18:39 rdp sshd[17955]: pam_unix(sshd:session): session opened for user scotty by (uid=0)
22:20
Apr 22 18:18:39 rdp sshd[17972]: Failed password for root from 10.0.0.108 port 3 7699 ssh2
22:20
Apr 22 18:18:39 rdp sshd[17972]: Failed password for root from 10.0.0.108 port 3
22:20
<vagrantc>
a mystery to us all.
22:21
<scotty_>
and a bunch more failed password for root., then close session for scotty
22:21
<vagrantc>
oh, you're using rdp to log in?
22:21
<scotty_>
Thanks, I will do that
22:21
no, rdp was the name I used for the server
22:21
<vagrantc>
that's an unusual default.
22:21
ah.
22:21
(ldm does, interestingly enough, have some support for RDP)
22:22
<scotty_>
all the business needs is terminals that can open an rdp connection to a remote server
22:22
yes, saw that. Wonder if it would auth with rdp as a backend
22:22
<vagrantc>
then you shouldn't need to log into the server via ldm, log into your actual RDP server ...
22:23
or use the rdesktop/xfreerdp scripts instead of LDM
22:23
<scotty_>
it's as though the x11 forwarding isn't working
22:24
<vagrantc>
scotty_: but the logs suggest that LDM is connecting once as the user, and then tries to connect using the root user.
22:24
<scotty_>
oh, so in the lts.conf file, the rdp just acts as a forward to the real (windoze) rdp server?
22:24
<vagrantc>
scotty_: LDM does make two login attempts, effectively, the first sets up a "master" connection, and the second uses that master connection to log in a second time
22:25
<scotty_>
yes. just not sure why
22:25gbaman has joined IRC (gbaman!~gbaman@members.unit1.farsetlabs.org.uk)
22:25
<scotty_>
the second through ssh, correct?
22:25
<vagrantc>
maybe for some bizarre reason it's failing to create the master socket, and so it attempts to ssh to the server as root?
22:25
both through ssh.
22:26
<scotty_>
that was a stupid question, sorry :-) obviously.
22:26
hmmm. looked through the audit log, not much help there either.
22:26
<vagrantc>
that's the only thing i can think of ... 10.0.0.108 is your thin client?
22:26GodFather has joined IRC (GodFather!~rcc@71-82-75-229.dhcp.bycy.mi.charter.com)
22:26
<scotty_>
another odd thing, it doesn't create and ldm log in var/log
22:27
an ldm log tha tis
22:27* vagrantc wishes fedora/redhat/centos/scientificlinux would just drop LTSP entirely rather than ship broken packages all these years
22:27
<vagrantc>
though i really wish someone would come along and maintain it properly
22:28
scotty_: on the client or on the server?
22:28
<scotty_>
yes, 108 is the thn client.
22:28
no ldm log on server.
22:29
should there be one on the client? Am I lbarking up the wrong tree?
22:29
<vagrantc>
yes, ldm runs on the client, not on the server.
22:29
ldm is basically a GUI frontend for "ssh -X"
22:29
<scotty_>
ahh.. thanks for that. let me try a shell login on it.
22:29* vagrantc tells small white lies to protect the truth
22:30
<scotty_>
:-)
22:31
edited lts.conf, restarting client
22:31
doe the debian version use ndb or nfs?
22:32
nbd... dyslexic fingers
22:34
ok.. ldm.log on client doesn't help a lot.
22:34
<vagrantc>
it can use either
22:34
or even AOE
22:34
defaults to NFS
22:37
<scotty_>
getting "started on client with ip address: 10.0.0.108, then calling rc.d init scripts, then calling rc.d pressh scripts, then authentication with backend ssh, then tarted on client with ip address: 10.0.0.108, then calling rc.d init scripts repeating. Guessing the first sucessfully authed witht he user, then many retries with root
22:37
cool, nfs I know better
22:39* vagrantc may need to sqitch to squashfs images via NFS for the future if overlay in the kernel doesn't get fixed to work with NFS

Do you have docs online to read your work / howtos?
22:42
So you recommedn I wait till saturday to get latest deb release then, or go with current?
22:43
<vagrantc>
you can try out the pre-release ... not much is likely to change in the next few days
22:45
i would definitely not recommend installing the current stable release, no reason to start with something soon to be deprecated :)
22:45
<scotty_>
Thanks, may give a try to get teh feel of things
22:45
<vagrantc>
(when soon is literally 3 days)
22:45
i gotta head out, but good luck!
