<bobby90>
@alksig - are you here?
19:44
<alkisg>
bobby90: yup
19:44
<bobby90>
unbelieveable... what TZ are you in? ;)
19:44
<alkisg>
Greece, UTC+2 now
19:45
<bobby90>
so, kali spera
19:46
<alkisg>
To you too :)
19:46
<bobby90>
just a small updae for you... I'm the guy where the KDE desktopsetings got corrupted through the LTSP.
19:47
<alkisg>
Ah right, so what happenned?
19:48
<bobby90>
I used Eclipse on the LTSP client, and on the next day, my .project file was gone. I also noticed some strange behaviour on the client. Maven builds were slow as hell and sometimes broke with some strange error message. This made me do some research.
19:49
I found on some (still rare) sources that some people consider sshfs less reliable than nfs, at least when load is high.
19:50
So my next step is to give nfs for /home a try. I will observe things for some time and eventually come back here and tellyou the story.
19:51
<alkisg>
bobby90: I'm aware of certain file system functions that are not available on sshfs
19:51
That's why we're using nfs here; more stable and faster
19:51
But I haven't heard anything about data corruption
19:51
And if one wants security, I'd advice nfs over wireshark, which protects everything
19:52
(or nfsv4 + kerberos, which has integrated security)
19:52
<bobby90>
Is that security thing a matter of encryption or authentication? which one is sacrificed on nfs?
19:53
<alkisg>
Both
19:53
A person with a laptop in your LAN could see everything, if he knows how
19:53
<bobby90>
So, someone who gains access to my network could access all user directories?
19:53
<alkisg>
(i.e. local root account)
19:53
Yes
19:53
That's why sshfs is the default
19:53
<bobby90>
I see.
19:53
<alkisg>
(as wireshark is a new comer now, it wasn't available in the past)
19:54
<bobby90>
Wireshark is a network analyzing tool to me... Is there something else with the same name?
19:55
<alkisg>
wireguard, sorry, I'm frequently confusing the name
19:55
<bobby90>
Ok, thanks
19:55
<alkisg>
It's an in-kernel vpn
19:55
<bobby90>
Interesting...
19:55
<alkisg>
(old age... :D)
19:55
<bobby90>
;)
19:55
<alkisg>
If you want to verify the sshfs issue, you could also try sshfs home in a standalone installation, without involving ltsp; if it happens there too, you'll know that sshfs is to blame
19:56
sshfs also has a few options with workarounds for known issues, but you'd need to investigate which one is that harms maven; if that's actually the case
19:56lucascastro has left IRC (lucascastro!~lucascast@177-185-131-162.corp.isotelco.net.br, Ping timeout: 245 seconds)
19:56
<bobby90>
Difficult. I cannot reproduce the problem.
19:57
I have sshfs on a Raspberry Pi that runs my Jenkins instance. It does Maven builds with no problem so far.
19:58
However, much slower, of course. Some 30 seconds for one of my projects on my deelopment machine, 5 minutes on the Pi.
19:59
The sshfs mounts a share from a Synology Diskstation.
20:01
So I'm still wondering if this is an sshfs problem or maybe an sshfs-on-ubuntu-20.04 problem.
20:02
I'll keep investigating...
20:08
<alkisg>
I've rarely seen such issues to be distro-specific
20:09
<bobby90>
Ok
20:12
I have just hat a look at my sshfs configuration on the Pi. There is nothing special. On the other hand, the sshfs is just used to expose a git repository. So it's a rad-mostly connection. Eclipse access to a project will run at some higher scale.
20:19
Where would I put options to be used by sshfs?
20:26
<alkisg>
bobby90: thousands of users are using sshfs without that issue; so IF that's the problem, it's related to the specific load
20:26
You can put it in SSH_OPTIONS in ltsp.conf
20:27
<bobby90>
the server or clients section?
20:27
<alkisg>
The clients section
20:30
<bobby90>
Do I need to restart something after a change?
20:30
Or just log off and on again?

ltsp initrd, then client reboot
