Comment on The Kerberos-hater's guide to installing Kerberos by Samuel

Samuel — Wed, 08 Feb 2012 19:51:27 +0000

I will second the use of FreeIPA and SSSD. It makes the use of Kerberos almost easy and it is rapidly improving. I use it in a school to manage logins and permissions.

Adam -

Thanks for the tip! I haven't heard of IPA but it's something I'll definitely take a look at very soon!

There is a muchg easier way to set up Kerberos now.

Try FreeIPA, or just IPA under RHEL 6.2 and later. It makes the install of Kerberos signifincantly less painful:

If you just run ipa-server install it will walkt you through the questions.

I run it in unattended mode:

ipa-server-install -U -r ` hostname | tr '[:lower:]' '[:upper:]'` -p freeipa4all -a freeipa4all --setup-dns --forwarder `awk '/nameserver/ {print $2}' /etc/resolv.conf `

It gives you:

LDAP
Kerberos
Certificate Authority
DNS

It configures Users and groups for you, as well as doing centralized SUDO and host based acces control. Works best in conjunction with SSSD on the client side.

I 'm also eagerly waiting for your 'how to' on Kerberos.

Man! I understood nothing. Every time I decide to learn Kerberos, I google for a couple of Howto, 2 hours later I quit

And to make this even more cumbersome: if you're trying to authenticate via LDAPs over the default nss_ldap package, you'll find it's been bugged for a few years in RHEL5 with noone stepping up to fix it. Good times.

Comment on CPAN: Automatically install dependencies without confirmation by Ashwini

Ashwini — Fri, 27 Jan 2012 08:19:36 +0000

Hi,

I have been facing issues with the last part of the installation:

First, pick a nearby continent and country by typing in the number(s)
in front of the item(s) you want to select. You can pick several of
each, separated by spaces. Then, you will be presented with a list of
URLs of CPAN mirrors in the countries you selected, along with
previously selected URLs. Select some of those URLs, or just keep the
old list. Finally, you will be prompted for any extra URLs -- file:,
ftp:, or http: -- that host a CPAN mirror.

(1) Africa
(2) Asia
(3) Central America
(4) Europe
(5) North America
(6) Oceania
(7) South America
Select your continent (or several nearby continents) []
Sorry! since you don't have any existing picks, you must make a
geographic selection.

Comment on Why I use Plesk by Major Hayden

Major Hayden — Thu, 26 Jan 2012 15:46:24 +0000

Emily -

I've found CPanel to be hit or miss for me in the past. There were some situations where it performed better and more reliably than Plesk, but it seems like Plesk did more of what I needed in the majority of situations.

Comment on Getting started with SELinux by Major Hayden

Major Hayden — Thu, 26 Jan 2012 15:45:30 +0000

Pieter -

Thanks! My goal was to get more people using SELinux and to give them the confidence to fix any problems that they find. I'll probably put together a post about writing SELinux policies (with audit2allow) pretty soon.

Comment on Getting started with SELinux by Pieter

Pieter — Thu, 26 Jan 2012 15:41:50 +0000

Nice tutorial. Hope you will keep it up with more information for example howto fix denials. A tutorial howto write policies would be really cool too although I guess that requires much more advanced knowledge about SELinux.

Cpanel anyone? Honestly, I've used Plesk, DirectAdmin and CPanel. I would recommend using cpanel any day. Have you looked into it at all?

Comment on Linux: Adjust storage kernel module load order by monke2123

monke2123 — Fri, 20 Jan 2012 18:11:41 +0000

I'm running Debian squeeze and had the same problem. The blacklisting and specifing the order in /etc/modules did not work for me.

per Tweeks suggestion I put:

alias scsi_hostadapter0 ahci
alias scsi_hostadapter1 sata_sil24

at the end of /etc/modprobe.d/aliases.conf and that did the trick for me.

(ahci the driver my system is using for the onboard sata drives)

Thanks Tweeks!

This is the best way to view chain numbers

iptables -L INPUT --line-numbers

you can also substitute with OUTPUT etc
