<aruke>
Hi everyone! Is there anybody here who is well red in to ltsp use of the nbd filesystem?
14:32
More directy to the point, is it possible to enable xattr to the clients root filesystem (I have some DRM issues when running local apps)

<vsuojanen>
aruke: don't know but I was going to test something like that xattr on fatclients. did you test it? maybe ubuntu channel could help with that too. what i understand it should be just mount 'some parameter' and you go with xattr or not
17:52
outch, you meant the nbd-client, sorry :)
17:53
(don't know)

<aruke>
vsuojanen: Yes, the NBD client. I can´t even find where the client calls the mount, and its not in fstab. The reference manual says its located somewhere in /linuxrc, but I can´t seem to find any mounting references. If I had found a fstab line I would have added the 'user_xattr' and been done with it.

<vsuojanen>
clients call the mount after the rootdev is up. the mount is there actually, right after nbd-client create the /dev/nbd0
20:04khildin has left IRC (khildin!~khildin@ip-213-49-86-232.dsl.scarlet.be, Quit: I'm gone, bye bye)
20:05
<vsuojanen>
all the rootmount processing is in /usr/share/initramfs-tools/scripts/local
20:06
<gp_>
I was going to set my clients up for remote logging and i saw this warning... "Enabling remote syslog with more than just a couple thin-clients on your network will cause unexpected results"
20:06
Is that still the case? The doc page seem to be older
20:07
<vsuojanen>
aruke there are initrd parameters ROOTFLAGS and LOOPFLAGS. Try the first
20:15
... where in earth that warning comes from? clients /etc/rsyslog.d/ has nothing like that
20:16
<aruke>
vsuojanen: Are you refering from the root of the server or the client chroot? (/usr/share/initramfs-tools/scripts/local)
20:19
<vsuojanen>
client. client does the mounting everytime.
20:21
<aruke>
gp_: I saw that warning to, it was in the documentation. The only thing I could think of was that it may add a significant amount of network traffic if you are running alot of clients. I selected to only activate logging on a per-host basis if I experience problems with a specific client.
20:22
<gp_>
aruke: Ah gotcha. that makes sense.
20:23
<vsuojanen>
i have used for clients a 15 min cronjob using logger
20:23
0,15,30,45 * * * * logger -d -n "$SERVER" -P 514 -t syslog_ping -p local7.info `uptime`
20:29
it should not be too much traffic if you filter the syslog messages
20:31
e.x. you can do the filtering in clients /usr/share/ltsp/init-ltsp.d/50-syslog
20:32
local7.* @${SYSLOG_HOST:-$SERVER}
20:37
so you add/pick some custom logging for your needs and remote logging filters for the remote server only what you have specified in 50-syslog script
