F21's questions

I got an alert from my VPS host that my VPS rebooted.

In /var/logs/auth.log, I see the following entry:

    Mar 17 19:09:34 master sshd[3558]: Server listening on 0.0.0.0 port 9922.
Mar 17 19:09:34 master sshd[3558]: Server listening on :: port 9922.

If I open the file with my text editor, the spaces before the first line are all NULs.

In /var/log/syslog, I see:

What could be the cause of the reboot?

I am installing a package called ArangoDB from their official apt repository: https://www.arangodb.com/repositories/arangodb2/xUbuntu_15.04/ /

All new versions for Ubuntu 15.04 would be published into that repository: 2.6.x, 2.7.x, 2.8.x, 3.x etc.

The current latest published versions are 2.6.9 and 2.7.0.

I am interested in only using the 2.6.x releases. Currently, if I do sudo apt-get dist-upgrade, it wants to upgrade me from 2.6.9 to 2.7.0, however I am not interested in upgrading to the 2.7.x branch.

This is the output of apt-cache show arangodb:

Is there anyway to set apt-get to only upgrade to a version in the 2.6.x branch?

I have an upstart script that I am converting to systemd. For this service to start, a certain network interface needs to be available.

This is what I am using in my upstart script:

start on (local-filesystems and net-device-added INTERFACE=tun0)

What's the systemd equivalent?

I have a Ubuntu 14.10 server with resolvconf installed.

In /etc/resolvconf/resolv.conf.d/base, I have:

nameserver 127.0.0.1

In /etc/resolvconf/resolv.conf.d/head, I have:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

In /etc/resolvconf/resolv.conf.d/original, I have:

domain members.linode.com
search members.linode.com
nameserver 207.192.69.4
nameserver 207.192.69.5
nameserver 97.107.133.4
options rotate

My /etc/resolvconf/resolv.conf.d/tail is symlinked to /etc/resolvconf/resolv.conf.d/original.

Why is my resolv.conf generated like this?

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 74.207.242.5
nameserver 74.207.241.5
nameserver 127.0.0.1
search members.linode.com
domain members.linode.com
search members.linode.com
nameserver 207.192.69.4
nameserver 207.192.69.5
nameserver 97.107.133.4
options rotate

Where are the first 2 and fourth lines from? From my understanding, resolvconf should only use information from head, base, and `tail.

This is my /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

I have Ubuntu 14.04 running as a VMware guest on my Windows 8.1 host.

I have shared a folder on my Windows Host and it is mounted in the Ubuntu guest on startup using this entry in fstab:

//myhost/work /work cifs credentials=/home/user/.smbcredentials,noserverino,nounix,uid=user,gid=user,file_mode=0777,dir_mode=0777 0 0

Why is it that when using node in interact with the share, sudo is required?

For example, if I use npm to install something (npm install --no-bin-links) on the share without sudo, I get a bunch of chmod errors:

npm ERR! Error: EPERM, chmod '/work/project/src/node_modules/webpack/package.json'
npm ERR!  { [Error: EPERM, chmod '/work/project/src/node_modules/webpack/package.json']

npm ERR!

npm ERR! Please include the following file with any support request:

If I install it using sudo npm install --no-bin-links, everything works fine.

The same problem occurs when I use gulp to watch and build my project: gulp watch results in the same chmod errors when building, but sudo gulp watch works fine.

Since the share is set to 0777, everyone is able to read and write to it. Why is it that I need to use sudo on node scripts?

I have Ubuntu 12.10 running as a VMware guest on my Windows 8 host.

I have shared a folder on my Windows 8 Host and it is mounted in the Ubuntu guest on startup using this entry in fstab:

//myhost/work /work cifs credentials=/home/user/.smbcredentials,noserverino,nounix,uid=user,gid=user,file_mode=0777,dir_mode=0777 0 0 

The share works fine and is able to be served by a webserver such as nginx.

However, there seems to be issues when I install node.js packages using npm, I get a bunch of errors like this:

What could be causing this problem? From the command line, I can chmod, rmdir among other things using sudo without any issues.

I have Ubuntu Desktop 12.10 running in VMware on my Windows 7 machine for development purposes. The VM is set up as "bridged", so effectively, it looks like it is directly connected to the same switch as my host PC.

Inside Ubuntu, I have compiled and install PHP 5.4.11 and nginx 1.2.6. PHP is compiled and configured to use PHP-FPM.

I also mounted a shared folder from my host using this:

//192.168.1.3/webfiles /webfiles cifs username=user,password=password,noserverino,file_mode=0777,dir_mode=0777 0 0 

This folder is then served by nginx and php-fpm.

Previously this has worked perfectly and is quite fast. However, yesterday, I installed software updates on my Ubuntu VM since the reminder kept popping up. The VM seemed fine as I was still able to work on it with out any issues last night.

This morning, I booted up the VM and was able to browse the shares in nautilus. However, once I visit a PHP page, the share would lock up for no reason! Nginx just shows a gateway timed out message and there was nothing relevant in the PHP logs.

I am at lost as to how this could have happened as the setup has worked fine for many months. I would like to further investigate the root of this problem to fix it.

Are there any logs for the samba share on Ubuntu I can inspect to do this? Has anyone had similar issues?

Currently, these are all I have in the logs:

log.wb-UBUNTU:

I have Ubuntu 12.10 installed in VMware Workstation as a guest. The VM's network adapter is set up as "bridge", so effectively, it should look like it is connected directly to the switch all my computers are connected to.

I am trying to make the VM connect to shares on the host. The host has a computer name of MyComp and workgroup of WORKGROUP. The host is running Windows 7 64-bit.

In Nautilus, I choose File > Connect to server. I then set it to Windows Share and try to connect to my computer. If I set MyComp as the server name, the connection will fail with Failed to retrieve share list from server. If I set it to the ip address 192.168.1.7, then it works.

I have done a bit of research and discovered that maybe it is because I don't have nmbd installed on the system. However, I believe it is part of the samba packages, which I do have:

user@ubuntu:~$ sudo apt-get install samba-common-bin smbclient samba-common
Reading package lists... Done
Building dependency tree       
Reading state information... Done
samba-common is already the newest version.
smbclient is already the newest version.
samba-common-bin is already the newest version.

Is there anyway I can connect to the windows share using the computer name?

I have a Ubuntu 12.10 guest that is running in VMware Workstation on a Windows 7 host.

I have created a shared folder so that Ubuntu can see a folder that lives on my Windows 7 host. I then set it up so that every time Ubuntu boots, the shared folder will be mounted under /files.

So far, everything works well. However, I created a second folder called /files2 and wish to use lsyncd to sync /files to /files2.

• lsyncd was installed using sudo apt-get install lsyncd.
• After installation, I created /etc/lsyncd/lsyncd.conf.lua.

This is my configuration file (etc/lsyncd/lsyncd.conf.lua)

sync {
    default.rsync,
    source    = "/www",
    target    = "/www2",
    rsyncOpts = "-ltuspogX",
    delay=0
}

The problem is that the sync never seems to happen, that is even if I restart or start/stop lsyncd.

Finally, if I ever create a file in the shared folder on the host machine (windows 7), I can see it in /files, but it never gets synced to /files2.

I need to get lsyncd to sync when I create/modify/delete folders in /files in my Ubuntu guest or Windows.

Is there anything in my configuration that I have missed to cause the sync to not work?

I have a 12.10 server setup in a virtual machine with its network set to bridged (essentially will be seen as a computer connected to my switch).

I installed opensshd via apt-get and was able to connect to the server using putty with my username and password.

I then set about trying to get it to use public/private key authentication. I did the following:

1. Generated the keys using PuttyGen.
2. Moved the public key to /etc/ssh/myusername/authorized_keys (I am using encrypted home directories).

3. Set up sshd_config like so:

   PubkeyAuthentication yes
   AuthorizedKeysFile /etc/ssh/%u/authorized_keys
   StrictModes no
   PasswordAuthentication no
   UsePAM yes
   

When I connect using putty or WinSCP, I get an error saying No supported authentication methods available (server sent public key).

If I run sshd in debug mode, I see:

PAM: initializing for "username"
PAM: setting PAM_RHOST to "192.168.1.7"
PAM: setting PAM_TTY to "ssh"

Why is this happening and how can I fix this?
