| 08:45 | <Eric3> Hi guys. Using ltsp-pnp how can i configure my fat clients to use cups with my settings and ppd like a regular ubuntu client ? with ltsp chroot classic, i was configuring everything inside my chroot. But with pnp cleanup scripts remove printers.conf settings. I can remove 50-printers-conf cleanup script but is there a recommended way / good practise to achieve that goal ?
| |
| 08:46 | <alkisg> You're supposed to port-forward the fat client printer on the server, and then setup the printer on the server itself
| |
| 08:46 | That way you can manage graphics driver installation etc with a GUI, not with a console
| |
| 08:46 | !jetpipe
| |
| 08:46 | <ltsp`> jetpipe: (#1) Jetpipe -script has founded to be unstable in some cases. You can try C written (but limited) Jetpipe from GitHub https://github.com/bilange/jetpipe or switch it to USB/IP and use these scripts http://pastebin.com/Ltdi2TCL Support AIO devices as well., or (#2) jetpipe has a bug in some Ubuntu versions, to manually start it, put something like this in lts.conf: RCFILE_01="/usr/sbin/jetpipe /dev/usb/lp0 9100 &"
| |
| 08:46 | <alkisg> RCFILE_01="/usr/sbin/jetpipe /dev/usb/lp0 9100 &"
| |
| 08:47 | So, you put that under a [mac-address] section, and then on the server you select add printer and put ltsp123.local there
| |
| 08:55 | <Eric3> ok thank you

| 16:03 | Chap has joined IRC (Chap!4a7b4a42@gateway/web/freenode/ip.74.123.74.66) | |
| 16:12 | <Chap> Hello! My fat clients think their hostname is different from the nameserver's hostname for them. Meaning, $ hostname on fat clients puts out ltsp415 and on the server the client's IP resolves to say host213. I've checked on the LTSP server in /etc/ltsp/dhcpd.conf and /var/lib/.../lts.conf and I can't see where hostname would be forced. Where are the places this could be set?
| |
| 16:16 | My server's dhcpd.conf does set ddns-hostname by pick(option host-name, second-option) so I'm guessing it's being requested by the fat client somehow... but I just can't find it!

| 16:27 | <alkisg_web> Chap: what is your subnet mask? is it /24 or e.g. /16?
| |
| 16:28 | Chap_ has joined IRC (Chap_!4a7b4a42@gateway/web/freenode/ip.74.123.74.66) | |
| 16:29 | <Chap_> The incorrect hostname also shows in the bottom-right of ldm greeter on fresh boot so it's not fired by a login script

| 16:31 | <alkisg_web> [19:26] <alkisg_web> Chap: what is your subnet mask? is it /24 or e.g. /16?
| |
| 16:34 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 16:34 | <Chap_> alkisg*: /16
| |
| 16:34 | And there are multiple subnets on this network
| |
| 16:35 | (clients are on a different /24 than the server)
| |
| 16:40 | I believe this is my fault, as I think I set this a *long* time ago, and it has propagated through updates we've made to dynamic dns
| |
| 16:43 | ..but I just.can't.find.it! -- I thought ack-grep was my friend :(
| |
| 16:49 | Leolo_2 has joined IRC (Leolo_2!~fil@24-54-27-253.mg.cgocable.ca) | |
| 16:51 | <alkisg_web> Chap_: ltsp names are automatically set from the ip and the subnet
| |
| 16:51 | Normally the ltsp server doesn't know anything about the ltsp client hostnames
| |
| 16:51 | So, you declared them in /etc/hosts or in your dns server
| |
| 16:51 | And then you changed your subnet to /16, so the clients changed their hostnames, so now your /etc/hosts or dns is broken
| |
| 16:52 | So, just update your /etc/hosts or dns with the correct values
| |
| 16:52 | <Chap_> alkisg_web: This has to be in the client tho right?
| |
| 16:53 | b/c the server's DNS looks a-ok (no reference to old name) and the server's /etc/hosts looks OK (no reference to old name)
| |
| 16:54 | <alkisg_web> The ltsp client don't have disks. They can't store state.
| |
| 16:54 | All state is stored on the server
| |
| 16:54 | <Chap_> Yes, I understand - by 'client' I mean 'image'
| |
| 16:56 | <alkisg_web> No, the image doesn't have dns information that propagates to the server
| |
| 16:56 | Wait, maybe you're talking about epoptes?
| |
| 16:56 | How are you checking the client names?
| |
| 16:57 | <Chap_> tty on fat client (ctrl+alt+f2) and $ hostname
| |
| 16:57 | <alkisg_web> OK, that's what the client knows
| |
| 16:57 | <Chap_> That shows the old one. On the server, who or w
| |
| 16:57 | <alkisg_web> How are you checking what the server knows?
| |
| 16:57 | <Chap_> which shows the new names
| |
| 16:58 | <alkisg_web> Where did you put the "new names", in your dns server?
| |
| 17:00 | <Chap_> New names handed out by /etc/ltsp/dhcpd.conf with a ddns-hostname = and then bind is updated when the lease is handed out
| |
| 17:00 | Yeah, new names are in bind
| |
| 17:01 | <alkisg_web> OK, so to phrase your issue correctly, "your ltsp clients use autogenerated hostnames instead of the ones you defined in dhcp"
| |
| 17:01 | I.e., your dhcp is misconfigured
| |
| 17:02 | Go to a client vt1, and type ipconfig -n eth0 and see if the server sends the correct hostname or not
| |
| 17:02 | Run `locate ipconfig` to find it; it's somewhere in /usr/lib/klibc/bin/ipconfig
| |
| 17:06 | <Chap_> Okay yeah! So ipconfig comes back with address, gateway, dns, domain but no hostname
| |
| 17:06 | <alkisg_web> OK, so the solution is to configure your dhcp properly :)
| |
| 17:06 | Or just don't send the hostnames via dhcp at all, and put the correct hostnames in your dns,
| |
| 17:06 | i.e. the ones that are the same as the autogenerated ones
| |
| 17:09 | Freejack has left IRC (Freejack!~quassel@unaffiliated/freejack, Quit: No Ping reply in 180 seconds.) | |
| 17:09 | <Chap_> Ok. I'll look into reconfiguring dhcpd and handing out leases. Thank you alkisg_web!
| |
| 17:09 | <alkisg_web> np
| |
| 17:10 | <Chap_> I think I should continue to send hostnames as other clients (byod) get leases from this dhcp server
