| 13:42 | <danboid> I'm trying to troubleshoot a new Debian 13 LTS image by enabling root login in ltsp.conf but the way that worked for me with Ubuntu isn't working for Debian.
| |
| 13:44 | The way that used to work for me with Ubuntu was to add the lines:
| |
| 13:44 | POST_INIT_SET_ROOT_HASH="section_set_root_hash"
| |
| 13:44 | [set_root_hash]
| |
| 13:44 | sed 's|^root:[^:]*:|root:HASHEDPASSWORD:|' -i /etc/shadow
| |
| 13:45 | Replacing HASHEDPASSWORD with a password hashed by mkpasswd
| |
| 13:47 | Gemini also suggested I try:
| |
| 13:47 | POST_INIT_SET_ROOT_HASH="usermod --password '$6$rounds=656000$re8X1v9K3J...$u81W4pXm...' root" in /etc/ltsp/ltsp.conf but that hasn't worked either
| |
| 14:13 | I then ran `ltsp initrd` before booting my client but I cannot login as root
| |
| 14:15 | <quinox> do you see /etc/shadow getting modified with your desired hash?
| |
| 14:16 | <danboid> When the clients booting?
| |
| 14:16 | <quinox> it should happen during booting, but you can check once it's fully booted
| |
| 14:17 | <danboid> How would I check once booted if I can't login and I can't scrollback?
| |
| 14:17 | I'm trying to troubleshoot LDAP not working
| |
| 14:18 | <quinox> ah
| |
| 14:19 | there's DEBUG_SHELL you can set to 1, it will put you in a root terminal when errors happen
| |
| 14:20 | <danboid> I'll give that a go then
| |
| 14:21 | <quinox> I myself use this one to set a root password: POST_ROOT="echo 'root:something' | chpasswd"
| |
| 14:21 | but there are many ways to Rome, your sed should be okay
| |
| 14:22 | (Assming the hash is fine, the hash algo is supported etc.)
| |
| 14:23 | not being able to log in to debug is tricky
| |
| 14:24 | you can do something like this: one 1 machine run "nc -l 1234", then put POST_INIT_ZZZZZZ="cat /etc/shadow | nc <ip of yuor 1 machine> 1234"
| |
| 14:25 | it sets up a listening process on 1 machine, and it sends data over during booting on the client
| |
| 14:25 | if stuff shows up you'll be able to see the content of /etc/shadow
| |
| 14:27 | if nothing shows up the command might not have triggered, it might not be able to reach your IP, etc
| |
| 14:28 | if you have a CDRom drive you can also try POST_TESTING="eject", it should open the tray during the boot :-)
| |
| 14:30 | <danboid> I knew there was a reason we should've kept optical drives
| |
| 14:58 | I think I'mm still running an ltsp from 2023. Do I need to upgrade for it to work with Debian 13 images?
| |
| 15:09 | <quinox> does Debian 13 use dracut?
| |
| 15:09 | If so: LTSP is not yet compatible with that
| |
| 15:14 | if it's from 2023 it should already be the new LTSP I think - works great for ubuntu, I don't know about Debian
| |
| 15:14 | stick around and someone with more knowledge will give a response
| |
| 15:14 | <danboid> Apparently not. At least one person on the LTSP github forum has said they've got debian 13 working with ltsp
| |
| 15:15 | I mean it appartently doesn'y use dracut
| |
| 15:15 | <quinox> https://ltsp.org/guides/netconsole/
| |
| 15:15 | do you build from a chroot or a vm?
| |
| 15:16 | I myself have LDAP working, but since I'm using a VM I can usually debug it in there
| |
| 15:17 | <danboid> vm
| |
| 15:17 | <quinox> and can you login on the VM using the LDAP?
| |
| 15:20 | <danboid> For some reason my nslcd config that was working under Ubuntu 20.04 doesn't seem to be working under Debian 13
| |
| 15:20 | Are you using nslcd?
| |
| 15:22 | <quinox> I'm using libpam-ldap
| |
| 15:22 | <danboid> I think thats what nslcd uses. You can use it standalone?
| |
| 15:26 | <quinox> not sure what you mean with standalone; I can log in on my VM using LDAP, and it works for booted LTSP as well
| |
| 15:27 | I have a bindpassword, the rest is all vanilla
