<leksmut[m]>
hello, let me share my experience. if don't see active hostnames for ltsp clients in the router dhcp server leases. just add to ltsp.conf in the [clients] section for all clients POST_INIT_REFRESH_DHCP="dhclient -r; dhclient"
06:42
<alkisg>
That can break networking
06:42sunweaver is back
06:43
<alkisg>
It's best to add DHCP/DNS reservations rather than rely on dynamic DNS, for LTSP clients
06:43
As PXE booting them doesn't send the hostname
06:43
As a bonus, then your DNS will work even when a client is offline
06:45
<leksmut[m]>
so use this on your risk try before productive use, as for me right now it works ok for my home lab. i got active hostnames.
06:47
active hostnames convinient for router scripting.
06:48
<alkisg>
Not sure what you mean... personally when I need DNS, I use static entries. When I need dynamic stuff, I use the preinstalled MDNS service, e.g. ltsp123.local (the .local hostnames).
06:48
That way it works in any router and with any client. I never needed anything beyond these...
06:57
<leksmut[m]>
i describe shortly my ltsp client laptop can PXE boot form its ethernet card and from its wificard so there is two MACs (MAC1,MAC2) corresponding one laptop. so in ltsp.conf i write [MAC1|MAC2] HOSTNAME = mylaptop and then now i can see mylaptop in the dhcp leases after that on the router side i can automatically add static DNS record for activehostname = mylaptop ... so mylaptop always has network name mylaptop.lan
06:58
<alkisg>
Your laptop always has the network name mylaptop.local without doing anything at all
06:59
<leksmut[m]>
i should check it maybe i ma overengineering things
06:59
thanks anyway
07:00
* thanks anyway, also MDNS should read about it

btw from my home lab experience ltsp client and sshfs can handle short network disconnection and even switching fom one NIC to another without rebooting. say we boot from wifi card via PXE then plug ethernet cable then change metric for link to switch traffic on ethernet and client still working good even faster cause over cable
07:58
* over cable. probably i should record screencast to proof that.

Hello ... may I ask for suport about a problem with font on ltsp client?
13:21
<err404[m]>
GiorgioVolpe: please ask
13:22
<GiorgioVolpe>
TKS! My setting: debian server with ltsp fat client. I install fonts in chroot, fc-cache -f, run "ltsp image" ... reboot client but can't see new fonts.
13:24
in in client: /var/cache/fontconfig ... contains some old cache files ... AND new ones. I can't understand where those old file comes from.

14:31
<alkisg1>
In general, LTSP doesn't touch fonts at all, so it's not really an LTSP issue but a chroot management issue... maintaining VM images or chrootless installations is a lot easier...

Hi all,
21:28
Is it possible to connect to a station with ssh, in replacement of epoptes ?
21:28
<alkisg1>
!sshd
21:28
<ltspbot>
sshd: Exposing sshd host keys over NFS is unsafe, so it's disabled by default and !epoptes is recommended instead. If you insist on running sshd in LTSP clients, read https://github.com/ltsp/ltsp/discussions/310#discussioncomment-101549
21:29
<jvfernandez[m]>
OK. Thank you.
