Does mysqld listen on the interface 1.2.3.4?
What happens when you try to connect with telnet? Like, 'telnet 1.2.3.4 3306'?

The article's author looks just as angry as me :) I'd put my signature under every word of it.

Thanks again.

I added one line to /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=1 biosdevname=0"
and rebooted after update-grub. Now, I've got all my eth's back! Thanks to everyone.

What remains...

After one more reboot, interface 'rename4' suddenly turned into 'em3'. Seems to be another case of https://bugs.launchpad.net/ubuntu/+source/biosdevname/+bug/1284043.

Having installed Ubuntu Server 14.04 on one a test server (HP Proliand DL380 G6 with 4 NICs), I was startled to see the interface names mangled in some weird way. What had been eth[0-3] for years...

Not that I was really annoyed by panels, and I've been working in an environment without panels for years (Stumpwm). I saw a default Ubuntu installation last week and this question came to my mind. I...

The old Gnome? The one with TWO panels? Shiver my timbers!

Do you think desktop panels (system trays, taskbars, what you may call it) are useful? If so, what information do you want to see in front of you every minute of your working day? Clock? CPU Disk...

Thank you, Ms.Daisy. No, I was rather talking about established TCP connections than wifi connections. I have seen some htop-like network monitors — iftop, iptraf, nethogs. But all they can do is to...

Hello,

I am looking for a tool that would be able to manage network connections, like `htop' can manage processes: kill them or block permanently. Do such tools exist?

I'm trying to write Upstart scripts for a program that I'd like to restart automatically, but cannot even start/stop it properly.

1. `pid file' won't work because there is no such file for the...

Even so, it would be more reasonable to use X tunneling from a workstation with GUI.

No solution, sorry, but, AFAIK, running Munin in CGI-mode is not recommended.

I use Munin in the plain cron-based configuration. You should not worry about performance penalty caused by running...

You can easily make users' home directories accessible via http, using Apache per-user web directories.

In vsftpd, this is done by uncommenting two lines in config:


# Uncomment this to allow local users to log in.
local_enable=YES
# You may specify an explicit list of local users to chroot() to...

Thank you, Sherl0k. What I'm certain about is that hardware RAID is a must on my servers. Its battery-backed cache can provide a higher performance than that of software-only RAID. I was rather...

Anyone, please?

Hello,

I have received a HP server with Ubuntu installed by someone else. There is Smart Array RAID controller installed there with cciss driver. And at the same time, there's device mapper...

Solution proposed at nginx mailing list was to use http_limit_req module together with http_geo module. First, we define a group of addresses in directive `geo' and then we set limits with...

Hello,

I'm thinking about some ways to limit access to my web-server. It runs Nginx and php in FCGI. The server contains a large amount of information. The data is freely available and no...

This header is appended by the SMTP daemon, not by the mail client. If it's sendmail, the format of the header is defined in the sendmail configuration file. I believe that other mail servers also...

Write a backup script and call it from crontab.

Have you been on Munin Exchange? There's a number of readymade plugins for Munin, and there's a chance that one of them will do what you want.

My usual daily peek at Munin reports normally stays on disk usage, MySQL connections, queries and slow queries, Nginx requests per second (mostly for the reasons of vanity), CPU usage (here I ponder...

Hello,

What do you think could be the reasons for suddenly increasing inode table size on an Ext4 on LVM? Munin draws mountainous landscapes like these:...
