| 12:00 | <Tottle> Hello,
| |
| 12:00 | statler has left IRC (statler!~Georg@gwrz3.lohn24.de, Remote host closed the connection) | |
| 12:00 | <Tottle> Hello,
| |
| 12:02 | statler has joined IRC (statler!~Georg@gwrz.lohn24.de) | |
| 12:02 | <Tottle> Hello,I want to report, that when I type e. g. 'sudo echo "Test"' into my terminal at a ltsp computer and than CTRL-C than I got a segementation fault. Could this be an potential security risk or is this normal due to some e. g. ssh internals?
| |
| 12:23 | <alkisg> Tottle: strange, I don't think anyone has reported anything like this
| |
| 12:23 | Tottle: does this happen on the ltsp server, or on a client?
| |
| 12:23 | Also, which ltsp version?
| |
| 12:37 | <Tottle> This happens only on the client. The version that I'm using is the default Ubuntu 18.04 apt version:
| |
| 12:37 | $ dpkg-query -W ltspltsp 20.01-1~202001301202~ubuntu18.04.1
| |
| 12:44 | <alkisg> Let me test here...
| |
| 12:50 | Tottle: yes, it happens on sshfs but not on nfs (which I use so I haven't seen that)
| |
| 12:50 | I believe it's a bug with sudo and locks on sshfs
| |
| 12:50 | It should be reported there
| |
| 12:51 | <Tottle> Ok, yes I'm using sshfs. Will you create an github issue
| |
| 12:52 | <alkisg> No
| |
| 12:52 | It needs to be reported in sudo and sshfs, not in ltsp
| |
| 12:52 | We cannot solve that from the ltsp side
| |
| 12:53 | <Tottle> Ah ok
| |
| 12:53 | <alkisg> I don't know where sudo maintains its code and bug tracker
| |
| 12:53 | You'd need to report it there
| |
| 12:54 | <Tottle> Ok did you know which line of sudo/sshfs code or code segment this comes from in ltsp
| |
| 12:54 | <alkisg> There's no code for that in ltsp
| |
| 12:54 | <Tottle> Ok
| |
| 12:54 | <alkisg> ltsp doesn't have the "sudo" word anywhere in its code
| |
| 12:55 | <Tottle> ok
| |
| 12:55 | <alkisg> It's like using libreoffice and finding a bug; ltsp doesn't have "libreoffice" anywhere in its code either
| |
| 12:56 | <Tottle> Ok, i thought it could have something to do with ltsp (or ssh in ltsp, now)
| |
| 12:57 | <alkisg> The same thing would happen if you used sshfs for /home in any pc
| |
| 12:57 | So it's either a bug in sudo or in sshfs
| |
| 13:00 | <Tottle> Ok, I will further investigate and report it
| |
| 13:00 | <alkisg> Great
| |
| 13:00 | * alkisg tests a bit too... | |
| 13:16 | <alkisg> Tottle: the problem might be "sudo on nfs", and not "sshfs or home related"
| |
| 13:17 | I don't have enough time now to look into it more
| |
| 13:26 | <Tottle> Ok so at the moment this is nothing that breaks something up, it's only strange. If I have time, I will also look further. Thank you for your time!

| 17:49 | <eu^5252118115> Yes! Says that sshfs: not found
| |
| 17:51 | How to create? I'm just setting up the first time
| |
| 17:59 | <alkisg> eu^5252118115: did you follow the installation page?
| |
| 17:59 | !install
| |
| 17:59 | <ltspbot> install: To install LTSP: https://ltsp.org/docs/installation/
| |
| 18:00 | <alkisg> eu^5252118115: the --install-recommends there is supposed to install sshfs for you
| |
| 18:00 | If you're using linux mint and you didn't use --install-recommends, then that was the problem
| |
| 18:03 | <eu^5252118115> Yes linux Mint use -install-recommends
| |
| 18:03 | <alkisg> eu^5252118115: dpkg -l sshfs
| |
| 18:03 | On the server. What does that show?

| |
| 18:08 | <alkisg> eu^5252118115: did you run `ltsp image` after you installed sshfs?
| |
| 18:08 | Why isn't it available on the client?
| |
| 18:09 | Are you using a VM, or chrootless?
| |
| 18:09 | If you're using a VM, then you need to install LTSP in the VM too
| |
| 18:14 | <eu^5252118115> I use VirtualBox VM thanks. It’s just that on my native system I had a IP conflict
| |
| 18:16 | Systems are identical only in downloadable no LTSP
| |
| 18:17 | As I understand it, put LTSP without setting
| |
| 18:20 | Thanks
