<julienfayad>
hello! quick question, how can I have my ltsp clients configured to use the KDC configured on the ltsp server (with ltsp pnp) ?
17:11
at the end my goal is to get the following:
17:12
1 the kerberos principal of the host added in the keytab of the client
17:12
2 a valid ticket for the logged in user (given the user is part of the KDC) so SSO can work properly
17:13
<||cw>
there's been some effort on that, I don't know the status. it is a fairly difficult problem as I understand it.
17:14
<julienfayad>
hmm any idea where can I check the status on that ?
17:15
as far as I know, I guess with the following ingredients that should be pretty easy to do:
17:15
<||cw>
not sure it's an official effort
17:15
<julienfayad>
1. Fix the hostname and IP addresses of the LTSP clients
17:16
2. Add the host in the KDC
17:16
3. Issue the write commands on the client (maybe through the RCFILE ?) to add the principal in the keytab
17:17
with that the client will be able to use kerberized services like NFS
17:17
<vagrantc>
hmm.
17:17
configure DHCP and DNS should fix the first issue
17:18
no idea how to add a host to the KDC
17:18
<julienfayad>
yup 1. is quite trivial
17:18
2. can be done on the KDC and it’s also quite easy
17:18
<vagrantc>
in general, we've been putting custom hooks that run on boot into /usr/share/ltsp/init-ltsp.d
17:19
main problem is likely that LDM doesn't do many of the typical Display Manager things ... it's basically a trumped up frontend to ssh.
17:19
so it might also require adding hooks to LDM to "do the right things"
17:20
it doesn't hook into PAM on the local machine at all
17:20
so if your kerberos setup relies on pam hooks ...
17:20
<julienfayad>
well I’m not 100% sure but I don’t think this might be an issue
17:21
<vagrantc>
me netierh
17:21
neither
17:21
<julienfayad>
what I noticed though is that the FAT client doesn’t get hold of all the config from the server
17:21
<vagrantc>
i'm assuming you're running fat clients, not thin clients?
17:21
<julienfayad>
like a kinit command just failed
17:22
<vagrantc>
all of what config?
17:22
<julienfayad>
the KDC config
17:23
double checking as we speak as I made some DNS changes that could also break that
17:24
<vagrantc>
well, LDM is not your typical display manager, so if you're having issues after resolving all of the above steps, that'd be the likely culprit
17:27
<julienfayad>
well wait I might know where’s the problem from
17:27
I’m updating the image to test
17:28
one off topic (out of curiosity) question though…
17:28
for ltsp-pnp we have to configure dnsmasq
17:28
yet since the clients are replicas of the server
17:29
wouldn’t this create a kind of conflict ?
17:29
<vagrantc>
ltsp-pnp excludes certain files or prevents certain software from running at boot
17:33
<julienfayad>
ok well I manage to get a kerberos ticket so I can add a principal to the keytab
17:34
<vagrantc>
does the machine get a ticket, or the user get a ticket at login?
17:34
or both?
17:35
<julienfayad>
actually none
17:35
I have to manually run the kinit command
17:35
to get a ticket
17:35
<vagrantc>
users normally run it manually when they want a ticket?
17:37
<julienfayad>
well on a basci install yes
17:38
there are some scripts to automatically get one at ssh login (which is what happens on an ltsp client, right ?) but I haven’t tried them yet…
17:38
<vagrantc>
as i said, LDM is very different.
17:39
yes, it uses ssh to log in to the server ... then it creates a local user based on the user's credentials on the server.
17:39
no idea if the credentials generated for ssh login on the server would be valid for the local fat client.
17:40
in your case
17:42
julienfayad: good luck
17:42
gotta head out
17:42
<julienfayad>
thanks vagrantc
17:42
you’ve helped me with the hint about services being stopped on ltsp clients
17:43
vagrantc++
17:43
as I could spot the rpc service is not running on the ltsp clients, in my case I’ll need it to mount a kerberized nfs drive
17:44
<vagrantc>
look at REMOVE_SYSTEM_SERVICES And KEEP_SYSTEM_SERVICES
17:44
should be documented in lts.conf in the ltsp-docs package ... i hope :)
17:46
<julienfayad>
yes I’ve checked it already, I need to identify all services that I’ll need first though
17:46
thanks for your help

hmm rpc seems unable to open a rpc_pipefs with the error no such file of directory...
17:54
I got to go, it would be cool to know how can I access ltsp client’s command lines though ssh in order to debug from outside the office… I know something with epoptes is possible anyone could explain ?
