<pedro>
Good morning.
11:31pedro is now known as Guest10412

<Guest10412>
I wonder if I can block some web page with Epoptes
11:32
<alkisg>
Guest10412: you can use epoptes to run a command that blocks web pages
11:33
It doesn't have a menu for it, though
11:33
<Guest10412>
Could you tell which command?
11:34
Ubuntu
11:34
<alkisg>
Are you using ltsp?
11:35
<Guest10412>
yes
11:35
<alkisg>
thin clients or fat clients?
11:35
<Guest10412>
both
11:36
<alkisg>
do you want to block access to all internet pages, or only to some of them?
11:36
and, for all users, or only for some of them?
11:39
<Guest10412>
To some pages (i.e. youtube) and for all user
11:39
<alkisg>
OK, then you can use dnsmasq as your dns server, and tell it to map youtube to 127.0.0.1, so that it doesn't find the real youtube
11:39
Are you using ltsp-pnp?
11:40
!ltsp-pnp
11:40
<ltsp>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
11:41
<Guest10412>
ok, i'll try with dnsmask
11:41
<alkisg>
ok

has anyone tried running ltsp in an lx zone from the illumos kernel?
18:18* vagrantc wonders why there is so much suffering in the world
18:23
<highvoltage>
because of fear, vagrantc
18:27
<vagrantc>
probably true
18:42
alkisg_away: can you sync directly from unstable, or does it have to be from testing?

<alkisg>
vagrantc: afaik, ubuntu lts release autosync from testing, and people that have enough rights can sync from anywhere... up to 15.10 LTSP was in main, so I didn't have access there, that was supposed to change for 16.04, I don't know if it did...
20:56uXus has joined IRC (uXus!~uXus@217.77.222.72)
20:58
<alkisg>
Nope, it looks like it's still in main, so I don't have upload rights, only stgraber does
21:06
<stgraber>
alkisg: all of ltsp is listed as being scheduled for demotion, let me see if I can just force them all to universe now
21:06
<alkisg>
Nice, that will give us a few more days for uploading the newer version
21:07
<stgraber>
alkisg: done, ltsp, ltspfs and ldm should all be in universe within the next couple of hours
21:08
<alkisg>
Thank you stgraber :)
21:08
stgraber: if needed, does that also mean that I can upload a new version directly to ubuntu, without it going to debian first?
21:08
<stgraber>
alkisg: yep
21:09
<alkisg>
Awesome! :)

22:02
vagrantc: ^^
22:07
<vagrantc>
sbalneav: you're really getting into pam modules... :)
22:09
<sbalneav>
vagrantc: I R teh PAM king.
22:11
<vagrantc>
sbalneav: what's it do that sudo doesn't?
22:12
<sbalneav>
"My thunderbird doesn't do XXXX"
22:12
ssh sbalneav@server
22:12
sudo su - user
22:12
thunderbird
22:13
"Can't open display: wrong credentials"
22:13
Now:
22:13
ssh -X user@server thunderbird
22:13
enter root password
22:13
magic.
22:13
<||cw>
ah, the old master magic password trick
22:16
<vagrantc>
hrm.
22:16
<sbalneav>
slick, no?
22:16* vagrantc would rather install temporary ssh keys
22:17
<vagrantc>
so the root password can be used to authenticate for any and all users?
22:17
<sbalneav>
With this module, yes.
22:18
My reasoning is: with the root password you can already CHANGE everyone's password.
22:18* vagrantc mostly builds systems without any root password
22:19
<sbalneav>
Then it's probably not for you :D
22:19* vagrantc nods
22:19ben_roose[EECS] has left IRC (ben_roose[EECS]!~roose@roose.cs.wichita.edu, Remote host closed the connection)
22:21
<sbalneav>
Note that you could provide a secondary account. Via the "superuser=" conf parm
22:21
So, you could create a local, NON PRIVILEDGED user, like:
22:21
"superdude:x:12:12:Super Account:/dev/null:/bin/false
22:22
and it has a valid password.
22:22
All it needs is a secondary password that it can find via getspnam
22:24
So, you could use this, even WITH passwordless root systems
22:25
<maldridge>
neat idea, I like the idea of using it with some kind of hardware token for the password

<||cw>
what I don't like about it is that there's no way to track who's making that connection, other than by client IP address
22:40
<maldridge>
well ideally the password would be infeasibly long, and you wouldn't have it up for long

maldridge: more of an accountability thing, less of a hacking thing.
22:47
<maldridge>
yeah, I'm at a small site where there are only 3 admins, we already all have root so this sort of thing wouldn't be that much different
