Make sure userid’s and groupid’s match between the systems

• e.g. usermod -u 1001 -g 504 -c "Andrew Fountain" andrewf

Set up the server

• set up the fully qualified domain name, e.g.

using smartmontools documentation, try:

smartctl -d sat,16 -i /dev/sdc # find if enabled
smartctl -d sat,16 -a /dev/sdc # display all info

• www.smartmontools.org/…tl.8.in
• www.cyberciti.biz/…ailing.html
• it.toolbox.com/…ng-to-do-31523

I you get “device is busy” when running umount, try

sudo lsof | grep /dev/xxxx
# or
sudo fuser -cu /dev/xxxx

• SCL is the way to go since it has RedHat’s blessing

Note that it is the .conf file that controls which version of php is used. For some reason this does not seem to be available for php55.

• create the script, e.g. /etc/init.d/mystartup.sh (see wiki.debian.org/LSBInitScripts )

#!/bin/bash
### BEGIN INIT INFO
# Provides:          mystartup
# Required-Start:    $all
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Enable Wine 16bit support
# Description:       Fix recommended by Linus to enable Wine 16bit support
### END INIT INFO
echo 1 > /proc/sys/abi/ldt16

• Then activate with:

chmod +x /etc/init.d/mystartup.sh
update-rc.d mystartup.sh defaults 99

Install on Ubuntu server

• from: wiki.x2go.org/doku.php/start

add-apt-repository ppa:x2go/stable
apt-get update
apt-get install x2goserver x2goserver-xsession
apt-get install python-software-properties
apt-get install x2godesktopsharing

• For Ubuntu 14:10, edit /etc/apt/sources.list.d/x2go-stable-utopic.list and replace trusty with utopic
• For Ubuntu 16:04 you will need to apply this fix:

export GSETTINGS_SCHEMA_DIR=/usr/share/mate:/usr/share/mate:/usr/local/

First: install server software and start it

yum install nfs-utils nfs-utils-lib system-config-nfs
yum install nfs-utils nfs4-acl-tools portmap
chkconfig nfs on
chkconfig portmap on
service nfs start
echo 'portmap:ALL' >> /etc/hosts.deny
echo 'portmap:192.168.1.0/24' >> /etc/hosts.allow
service portmap start

run the firewall gui and turn on NFS4 (2049)

• Modify /etc/fuse.conf to uncomment the line: user_allow_other
• Add the user to the fuse group:

adduser $USER fuse

• relogin to get access

Connecting interactively:

sshfs -o allow_other,umask=117,uid=1002,gid=1002 myname@sv:/home/common /home/myname/common

Connecting through fstab

• Note that it is best to connect on demand in case the network is not up when fstab runs originally
• Four steps are required:

1. Add user to fuse group
   • See above
2. Insert entry into fstab of client computer

myname@sv:/home/common  /home/myname/common fuse.sshfs users,_netdev,noauto,x-systemd.automount,reconnect,allow_other,workaround=rename,umask=117,uid=1002,gid=1002 0 0

3. Mount shares on logon
   • Can place a mount script in ./kde/Autostart e.g.

#!/bin/bash
# must already be in /etc/fstab
mount ~/common
mount ~/personal

4. Enable password-less logon
   • See here: /how-create-password-less-ssh-login
   • Don’t forget to make sure server home directory is as least as secure as 750
