| 06:55 | <alkisg> mwalters: from what I can see, the problem with the uefi clients not requesting any files, was because I was offering both pxe-service and dhcp-boot. Those need to be separated; real dhcp gets dhcp-boot and proxydhcp gets pxe-service.
| |
| 06:55 | I think that's actually a bug in dnsmasq, but anyway that ^ workaround solves it

| 11:59 | <uumas> Is there a way to prevent people from connecting to the ltsp server through ssh, but still let them sign in to the clients?
| |
| 12:00 | <alkisg> Do you mean fat clients?
| |
| 12:00 | <uumas> Yes
| |
| 12:00 | <alkisg> You can allow ssh logins only from local subnet and only for specific users
| |
| 12:00 | If that's not enough, set LDM_SERVER elsewhere, e.g. in a vm,
| |
| 12:01 | and, it's also possible to use chroots in ssh, although more difficult to setup
| |
| 12:01 | The LDM login manager doesn't support anything other than ssh
| |
| 12:02 | <uumas> Okay, would it be possible to use another login manager and login "locally"
| |
| 12:02 | We have authentication through LDAP
| |
| 12:02 | <alkisg> No, ltsp doesn't support other display managers
| |
| 12:02 | Well...
| |
| 12:02 | you could, if you rewrote that part of lstp
| |
| 12:02 | if you know programming, you should be able to do it within a couple of days
| |
| 12:03 | <uumas> Okay, well, that sounds like quite a bit too much trouble then.
| |
| 12:04 | What harm could a normal user cause on the server. One thing that comes to my mind is fork bombs, but is there anything else?

| 13:18 | josefig has left IRC (josefig!~jose@unaffiliated/josefig, Ping timeout: 240 seconds) | |
| 13:35 | <mwalters> they'll be confined to their own userspace... they could fill up /home, I guess? They could do that from their own client regardless, though
| |
| 13:35 | alkisg: I'll take a look at that, thanks
| |
| 13:40 | oh, so you're saying that bios clients don't need the pxe-service line?
| |
| 13:40 | (for X86PC)?
| |
| 13:41 | I think I'm more confused now, sorry. :D
| |
| 15:10 | spaced0ut has joined IRC (spaced0ut!~spaced0ut@unaffiliated/spaced0ut) | |
| 15:36 | <alkisg> mwalters: are you using proxydhcp or real dhcp?
| |
| 15:36 | <mwalters> real dhcp
| |
| 15:36 | <alkisg> Then don't put any pxe-service lines at all
| |
| 15:36 | <mwalters> (e.g., my ltsp servers are the dhcp servers, proper)
| |
| 15:36 | <alkisg> For any client (except raspberries, if you have)
| |
| 15:36 | <mwalters> thanks, I'll try that
| |
| 15:36 | <alkisg> np
| |
| 15:48 | <mwalters> that worked, thanks!
| |
| 15:48 | I lost so much hair over that one
| |
| 15:50 | <alkisg> Me too :)
| |
| 15:50 | Hours and hours, until the bulb was lighted over my head
| |
| 15:51 | <mwalters> hah! The one day I had made waaaay too many changes in the conf and it worked... so I knew it was at least a config issue... but I never could narrow it back down, lol

| 19:17 | JuJUBee has joined IRC (JuJUBee!~knichel@24.105.212.11) | |
| 19:18 | <JuJUBee> so I originally setup ltsp as dual nic, but I have not been able to finish everything else and need it to be single nic. How do I switch?
| |
| 19:20 | DO I just re-run ltsp-config dnsmasq ? what about iptables?

| 19:59 | <JuJUBee> My clients are able to boot and connect to internet now, but my ltsp server has not internet access. I set the default gw in network-manager for the interface connected to the lan.
| |
| 20:00 | <Hyperbyte> JuJUBee, your problem is not ltsp related.
| |
| 20:01 | Just debug your internet connection on the server. Check your network configuration, ping the next gateway, traceroute, etc.
| |
| 20:01 | Use any guide online to troubleshoot internet connection on Linux.
| |
| 20:01 | <JuJUBee> There is no default gw for some reason when I "ip route" or route -n
| |
| 20:02 | When I configured ltsp originally I used dual nic config, but now I am only using a single nic until I can finish setting everything else up (web server etc....)

| |
| 20:09 | this should help, like Hyperbyte said, this isn't specific to LTSP
