| 16:18 | <eu^zibilinsecopl> Hi everyone!
| |
| 16:28 | <alkisg> Hello
| |
| 16:29 | <eu^zibilinsecopl> I've started to prepare ldap authentication on ltsp
| |
| 16:30 | sssd configured on serwer + sssd preconfigured in client image
| |
| 16:31 | has anyone working such configuration?
| |
| 16:32 | vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc) | |
| 16:33 | <eu^zibilinsecopl> I have many servers LTSP5 working with LDAP and need to prepare working it in new LTSP
| |
| 16:34 | btw: big thanks for huge work on new LTSP, it's great !

| 17:34 | <alkisg> zibi: I think some people have working ldap, google for ldap site:github.com/ltsp
| |
| 17:56 | When funding is found, we'll add official support for ldap, ad or sssd...
| |
| 18:03 | <zibi> Now I can login on client with LDAP credentials, without emting 54-pam.sh, but need to mount homedir by sshfs yet
| |
| 18:07 | <alkisg> I think a few code lines would need to be changed in order to use sshfs with ldap on the client
| |
| 18:08 | woernie has left IRC (woernie!~werner@p5ddec4e7.dip0.t-ipconnect.de, Ping timeout: 246 seconds) | |
| 18:08 | <zibi> hope so :)
| |
| 18:08 | <alkisg> If you have it working with nfs home, then it shouldn't be very hard :)
| |
| 18:09 | <zibi> I think sshfs is more secure, so it's better solution for me
| |
| 18:10 | <alkisg> Sure
| |
| 18:11 | <zibi> Using sssd is common for LDAP and AD so I thing is proper way
| |
| 18:11 | <alkisg> I don't think the exact pam module will matter, it will just mean that the user isn't local
| |
| 18:12 | so "authenticate without searching for the user in /etc/passwd"
| |
| 18:12 | <zibi> but need to configure it on client image
| |
| 18:13 | right
| |
| 18:15 | Do you use swap over NBD? I think it's necessary to have swap on clients
| |
| 18:22 | <alkisg> This has numerous problems, it's best to have local swap, e.g. in usb stick or local disk
| |
| 18:22 | This is used automatically
| |
| 18:33 | <quinox> (I give my clients 8GB to 32GB of ram and run them without swap)

| 18:39 | <alkisg> When a client needs to use swap, it saturates the network and the server cpu so much, that it affects ALL other clients
| |
| 18:40 | <zibi> yes, it can slow down all clients
| |
| 18:40 | <alkisg> Maybe this will get better in the future with systemd oomd, we'll see; currently it's a bad idea
| |
| 18:40 | We did use that in ltsp5, and it caused so many problems that I didn't want to reimplement it as is
| |
| 18:41 | So now I'm just using local swap in schools that need it
| |
| 18:41 | lucascastro has joined IRC (lucascastro!~lucascast@177-185-133-227.dynamic.isotelco.net.br) | |
| 18:41 | <alkisg> You can very easily enable swap in ltsp20, it just needs an nfs-rw directory and mkswap/swapon commands in POST_INIT_x
| |
| 18:42 | E.g . /srv/ltsp/swap/$MAC_ADDRESS.swap
| |
| 18:43 | <zibi> I have such situation of slow down all clients in LTSP5 when some of them open an application with hard working graphics
