[Ltsp-discuss] Can't set up Ubuntu 16.04 LTSP with NFS

[Мокрозуб В.А.]

Hello,



I'm trying to configure LTSP to use NFS on Ubuntu 16.04 (it uses NBD by
default).



First, I added to /etc/exports:

##

/opt/ltsp/i386_xenial *(ro,no_root_squash,async,no_subtree_check)

##



Then I created PXE config file
/var/lib/tftpboot/ltsp/i386_xenial/pxelinux.cfg/default:

##

default ltsp-NFS

ontimeout ltsp-NFS



label ltsp-NFS

menu label LTSP, using NFS

kernel vmlinuz

append ro initrd=initrd.img init=/sbin/init-ltsp forcepae root=/dev/nfs
ip=dhcp boot=nfs rootpath=/opt/ltsp/i386_xenial

ipappend 2

##



The client succesfully booted but I couldn't log in. After some search I
discovered that all system files are not writeable by root though they have
644 permissions. However, they can be made writeable with chmod:

##

***@vma-test:~# ls -l /etc/environment

-rw-r--r-- 1 root root 96 ÏËÔ 3 14:07 /etc/environment



***@vma-test:~# echo '#test' >> /etc/environment

-bash: /etc/environment: Permission denied



***@vma-test:~# chmod 644 /etc/environment



***@vma-test:~# ls -l /etc/environment

-rw-r--r-- 1 root root 96 ÏËÔ 3 14:07 /etc/environment



***@vma-test:~# echo '#test' >> /etc/environment



***@vma-test:~# cat /etc/environment

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/game
s:/usr/local/games"

#test



***@vma-test:~#

##



NBD works ok so I guess there's something wrong with my NFS configarion.

Thanks in advance.
