| 06:14 | <ltspbot`> I do not know about 'lower', but I do know about these similar topics: 'lowercase-mac'
| |
| 06:14 | <alkisg> !lowercase-mac
| |
| 06:14 | <ltspbot`> lowercase-mac: The new ltsp.conf expects mac addresses in lowercase. Here's a command to convert them: sed -E 's/([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}/\L&/' -i ltsp.conf

| 17:30 | <poolavto> hi
| |
| 17:31 | Why is the /etc/resolv.conf file being deleted from my clients
| |
| 18:17 | Help please
| |
| 18:18 | <alkisg> poolavto: hello
| |
| 18:18 | You can set the DNS server for your clients from DHCP or from ltsp.conf > DNS_SERVER
| |
| 18:18 | <poolavto> in the file /etc/ltsp/ltsp.conf DNS_SERVER is registered
| |
| 18:18 | <alkisg> You don't need to handle /etc/resolv.conf manually
| |
| 18:19 | What's the output of this command on the clients? ls -l /etc/resolv.conf
| |
| 18:20 | <poolavto> no such file
| |
| 18:21 | <alkisg> How are you managing the ltsp image? Is it chrootless? VM? chroot?
| |
| 18:21 | <poolavto> chrootless
| |
| 18:21 | <alkisg> And what's the output of `ls -l /etc/resolv.conf` in your ltsp server?
| |
| 18:22 | <poolavto> -rw-r--r-- 1 root root 54 июн 20 21:45 /etc/resolv.conf
| |
| 18:23 | <alkisg> Normally /etc/resolv.conf is a symlink to systemd-resolved
| |
| 18:23 | Do you have a reason to use a non-standard setup?
| |
| 18:24 | /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf
| |
| 18:26 | Which distribution/version are you using?
| |
| 18:28 | <poolavto> DISTRIB_ID="AstraLinuxCE"
| |
| 18:28 | DISTRIB_DESCRIPTION="Astra Linux CE 2.12.44 (Orel)"
| |
| 18:28 | DISTRIB_RELEASE=2.12.44
| |
| 18:28 | DISTRIB_CODENAME=orel
| |
| 18:28 | PRETTY_NAME="Astra Linux (Orel 2.12.44)"
| |
| 18:28 | NAME="Astra Linux (Orel)"
| |
| 18:28 | ID=astra
| |
| 18:28 | ID_LIKE=debian
| |
| 18:28 | ANSI_COLOR="1;31"
| |
| 18:31 | <alkisg> What's the output of `uname -a` ?
| |
| 18:32 | Since it's an unknown distribution, and since I don't have a lot of time, would you mind sharing you screen with me so that I check out faster what it's doing with resolv.conf?
| |
| 18:32 | !vnc-dide
| |
| 18:32 | <ltspbot`> vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.
| |
| 18:33 | <alkisg> It says it's based on debian and kernel 5.4, but debian uses systemd-resolved, not plain /etc/resolv.conf. And even with a plain resolv.conf, ltsp should still work properly
| |
| 18:44 | poolavto: something weird is going on, can I install virtualbox on the server to test with a VM client, so that I see the boot process?
| |
| 18:44 | If I run the config_dns function manually, it does create resolv.conf properly
| |
| 18:44 | Or if you just want to work around the issue, you can use a POST_INIT="echo nameserver 8.8.8.8 > /etc/resolv.conf"
| |
| 18:45 | Let's do that ^...
| |
| 18:53 | poolavto: it's not LTSP. Something else in your setup is deleting resolv.conf
| |
| 18:53 | As a workaround, the POST_SERVICE_RESOLV_CONF command creates it later on in the boot process
| |
| 18:54 | Anyway , problem solved :)
| |
| 18:54 | <poolavto> so good)))
| |
| 18:54 | senkyou very much))
| |
| 18:54 | <alkisg> You're welcome :)
| |
| 18:55 | <poolavto> And which file should be copied to the new server to make everything work?
| |
| 18:55 | <alkisg> Just the POST_SERVICE_RESOLV_CONF line in ltsp.conf
| |
| 18:56 | POST_SERVICE_RESOLV_CONF="echo nameserver 8.8.8.8 >/etc/resolv.conf"
| |
| 18:56 | <poolavto> big senkyou))
| |
| 18:56 | I need to configure a lot of servers on this OS
| |
| 18:56 | <alkisg> 👍️
