Still exciting to have new, beta but i find noting interesting so far. Minor improvements, driver updates, new hardware support etc.
here is the full announcement link.
Drop a line to share your opinion.
Just crossed over engadget and look at that pretty screenshots hit the more link:
Run:
apt-get install vim-nox
and then:
update-alternatives --config editor and select vim-nox:
evil:/tmp/# update-alternatives --config editor
There are 4 alternatives which provide `editor'.
Selection Alternative
-----------------------------------------------
1 /bin/ed
*+ 2 /bin/nano
3 /usr/bin/vim.tiny
4 /usr/bin/vim.nox
Press enter to keep the default[*], or type selection number: <-- 4
Using '/usr/bin/vim.nox' to provide 'editor'.
evil:/tmp/#
Choose the one you like most, voila.
Shoud work on ubuntu and other derivates too.
Something interesting i spotted on Karansbir’s blog:
Running dstat normally gives you something like this :
# dstat --nocolor ----total-cpu-usage---- -dsk/total- -net/total- ---paging-- ---system-- usr sys idl wai hiq siq| read writ| recv send| in out | int csw 3 0 97 0 0 0| 820k 456k| 0 0 | 800B 866B|1054 255
And you can split the disk metrics up based on devices using something like this :
# dstat -D sda,sdb,total --nocolor ----total-cpu-usage---- --dsk/sda-- --dsk/sdb-- -dsk/total- -net/total- ---paging-- ---system-- usr sys idl wai hiq siq| read writ: read writ: read writ| recv send| in out | int csw 1 1 97 0 0 0| 176k 77k: 30k 162k: 411k 478k| 0 0 |3608B 4005B|1447 1458 33 2 63 0 1 2| 0 0 : 0 216k: 0 432k|2470k 1611k| 0 0 |2915 6967 31 2 65 0 1 1| 0 0 : 0 0 : 0 0 |2210k 1338k| 0 0 |2866 6051
But you can also get deeper level device names / nodes to measure – which is required in many cases if you have drivers for storage creating nodes further down the tree than /dev. Eg. I have a setup where there are four mysql instances running, each with its own dedicated storage :
# mount | grep srv /dev/cciss/c0d1 on /var/lib/mysql/node1 type ext3 (rw) /dev/cciss/c0d2 on /var/lib/mysql/node2 type ext3 (rw) /dev/cciss/c0d3 on /var/lib/mysql/node3 type ext3 (rw) /dev/cciss/c0d4 on /var/lib/mysql/node4 type ext3 (rw) /dev/cciss/c0d5 on /srv/wal type ext3 (rw)
so in this case, to get dstat reporting working you need to mention just the component level, like this :
# dstat -D cciss/c0d1,cciss/c0d2,cciss/c0d3 --nocolor ----total-cpu-usage---- dsk/cciss/c dsk/cciss/c dsk/cciss/c -net/total- ---paging-- ---system-- usr sys idl wai hiq siq| read writ: read writ: read writ| recv send| in out | int csw 3 0 97 0 0 0| 209k 89k: 201k 86k: 204k 85k| 0 0 | 799B 865B|1055 256 90 1 8 1 0 0|3196k 68k: 764k 0 : 816k 24k|1067k 1650k| 0 0 |1999 609 95 1 3 1 0 0|2548k 0 : 0 4084k:2448k 5700k| 660k 791k| 0 0 |1611 571 96 1 2 1 0 0|2628k 0 : 808k 0 :1620k 0 | 352k 798k| 0 0 |1835 1605
And you get the details, for each block device.
How do you fix the issue with a SSH server which freezes after authenticating?
$ ssh root@xxx.xxx.xxx.xxx
The authenticity of host ‘xx.xx.xxx.xxx (xx.xx.xxx.xxx)’ can’t be established.
RSA key fingerprint is replaced for security.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘xx.xx.xxx.xxx’ (RSA) to the list of known hosts.
Password:
PTY allocation request failed on channel 0
In the above scenario, you can see that I logged in but I’m not able to get into the console.
Once you’re in debug more, you will see lots of messages elaborating the SSH access steps in detail. These messages might point you to the root cause or the stage at which you’re being locked.
In my case, I got freezed after authenticating myself.
Resolution is just to make pts and restart sshd
mkdir /dev/pts mount /dev/pts /etc/init.d/ssh restart
and permanent solution is just instaling udev via:
apt-get install udev
Simply put, a ‘runlevel’ determines which programs are executed at system startup. Most of your exposure to run levels will deal with system startup. You will become intimately familiar with the exceptions the first time you have to troubleshoot a failed system.
Linux run levels are numbered 0 through 6. Run levels stop at six for practical and historical reasons, but it is entirely possible to have more if desired.
The following table summarises the UserLinux run levels:
* 0 System Halt * 1 Single user * 2 Full multi-user mode (Default) * 3-5 Same as 2 * 6 System Reboot
When run levels are discussed they are referred to as ‘moving into’, or ‘going into’ a certain run level. The inference is that you came from somewhere. With the exception of booting up, a system always transitions from one runlevel to another in response to certain conditions.
Special Run Levels
Run level 0 is the system halt condition. Nearly all modern X86 computers will power off automatically when run level 0 is reached. Older X86 computers, and various different architectures will remain powered on and display a message referring to the halt condition.
Run Level 1 is known as ‘single user’ mode. A more apt description would be ‘rescue’, or ‘trouble-shooting’ mode. In run level 1, no daemons (services) are started. Hopefully single user mode will allow you to fix whatever made the transition to rescue mode necessary.
(You can boot into single user mode typically by using your boot loader, lilo or grub, to add the word ‘single’ to the end of the kernel command line).
Run levels 2 through 5 are full multi-user mode and are the same in a default UserLinux (Debian) system. It is a common practise in other Linux distributions to use run level 3 for a text console login and run level 5 for a graphical login.
Run level 6 is used to signal system reboot. This is just like run level 0 except a reboot is issued at the end of the sequence instead of a power off.
In the interests of completeness, there is also a runlevel ‘S’ that the system uses on it’s way to another runlevel. Read the man page for the init command (“man init“) for more information, but you can safely skip this for all practical purposes.
Where Does a Run Level Live?
Like everything else in a Linux system, run levels are defined by files in the filesystem. All the run level files are found in the /etc directory according to the following table:
/etc/rc0.d Run level 0 /etc/rc1.d Run level 1 /etc/rc2.d Run level 2 /etc/rc3.d Run level 3 /etc/rc4.d Run level 4 /etc/rc5.d Run level 5 /etc/rc6.d Run level 6
Notice a pattern? Each defined runlevel should have an rcX.d directory where X is the run level number. The contents of the rcX.d directory determines what happens at that run level.
(S)tart files, (K)ill files
Let’s look at run level 2 since this is where we’ll spend most of our time.
Here are the contents of a generic rc2.d directory:
S10sysklogd S20cupsys S20mailman S20usermin S91apache S99xdm S11klogd S20exim4 S20makedev S20xfs S91apache2 S14ppp S20fam S20pcmcia S20xprint S99gdm S18portmap S20hylafax S20samba S89atd S99rmnologin S20acpid S20inetd S20ssh S89cron S99stop-bootlogd
At first glance the files in this directory look kind of intimidating. They should be. The files in the rcX.d directories are formatted for the computer to read, not the user.
Each file is a symbolic link to a script residing in the /etc/init.d directory and controls the starting, or stopping of a program, or daemon (service).
This is important enough to say again, each file is a symbolic link to a script and controls the starting, or stopping of a program, or daemon.
In slightly modified man page format, here is how the files are named:
[K | S] + nn + [string]
Working backwards, here is how the name parses out. The [string] is a human readable mnemonic for the executable file that is actually symbolically linked to. The ‘nn’ is a two digit number from 01-99; lower number programs are executed first. By this method, services that have a dependancy can be certain their precursor has ran. The K and S signify simply Kill, or Start.
When a system moves into a new runlevel, all the files that begin with S will be executed. When a system moves into a new runlevel all the files that begin with K will be executed. Yes, all the files will execute, but with one distinct difference: ‘S’ files invoke their program with the ‘start’ parameter, the ‘K’ files invoke their program with the ‘stop’ parameter. The UserLinux (Debian) system optimizes the runlevel change by not starting a daemon that is already running.
The simple elegance of this system is made possible by the alphabet. All the scripts will execute in alphabetical order. ‘K’ comes before ‘S’, so programs are stopped before they are started. Forgetting this fact can lead to a lot of chin scratching while manipulating your rcX.d files.
After the first letter comes the integer, again determining execution order. Finally, the mnemonic portion is followed alphabetically to determine execution order.
Let’s look at some of the programs that are actually executed during a run level change:
S20exim4 -> ../init.d/exim4 S20fam -> ../init.d/fam S20hylafax -> ../init.d/hylafax S20inetd -> ../init.d/inetd S20mailman -> ../init.d/mailman S20makedev -> ../init.d/makedev S20pcmcia -> ../init.d/pcmcia S20samba -> ../init.d/samba S20ssh -> ../init.d/ssh
All of these files have the same precedence as far as the system is concerned. They will be executed in the order listed, i.e. alphabetically.
All of the scripts that run during system start-up actually reside in the /etc/init.d/ directory, as suggested by the listing. The reasons for this are many, but basically boil down to common sense issues like: saving space, single point for editing, and everyone knowing where to find things.
Transitioning Between Run levels
When you leave a runlevel, nothing happens. All the action takes place when you enter the new run level.
Look at the following two rcX.d listings:
rc2.d:
K01xdm S18portmap S20fam S20makedev S20usermin S89cron S99rmnologin S10sysklogd S20acpid S20hylafax S20pcmcia S20xfs S91apache S99stop-bootlogd S11klogd S20cupsys S20inetd S20samba S20xprint S91apache2 S99xdm S14ppp S20exim4 S20mailman S20ssh S89atd S99gdm
rc3.d:
K01gdm S20acpid S20inetd S20ssh S89cron S99xdm S10sysklogd S20cupsys S20mailman S20usermin S91apache S11klogd S20exim4 S20makedev S20xfs S91apache2 S14ppp S20fam S20pcmcia S20xprint S99rmnologin S18portmap S20hylafax S20samba S89atd S99stop-bootlogd
Look intensely at the two listings while allowing your eyes to unfocus. An image of a gnu will eventually appear. Ok, no it won’t, but you believed for just a second, didn’t you?
Look at the first listing, rc2.d. Notice the contradiction between the first program and the last program. K01xdm instructs the system to Kill xdm upon entering run level 2; S99xdm tells the system to start xdm. Who wins? Both programs are executed, but the last program to run will prevail. S99xdm, as it appears last in the alphabetical sequence, will leave xdm in a running state. The change to runlevel 2 was wasted typing.
Now, let’s look closely at the rc3.d listing. The first thing that will be executed is the stopping of gdm, which is the default graphical display manager for UserLinux (Debian). Note the S99gdm file (symlink) has been removed. The purpose of the change is to move to a runlevel where everything else is still running, except the pretty window manager. This situation is called ‘console mode’. As mentioned previously, many Linux distributions use run level 3 for console mode.
That’s great, but how do I change run levels?
Before we change run levels it might help to find out which run level is current. Use the ‘runlevel‘ command to tell you two things: The last run level, and the current run level. Here is the command and the output shown together due to the sparsity of the output:
ulsoho:/home/user1# runlevel N 2
The ‘N’ stands for none, meaning there has been no run level change since powering up.
The init system controls run levels, but then again, the init system pretty much controls everything. The init system will be looked at in detail in a future article.
The primary command used to change run levels is ‘telinit‘. Get it? “Tell Init” to do something; like this:
telinit 3
telinit takes one argument on the command line. As always, see the man page for full details. Normally the argument will be one of: 0,1,2,3,4,5,6, or the letter ‘S’. As you may have guessed, the numbers correspond to the run level you wish to move to. Using the ‘S’, for single-user, is the same as the number 1, but don’t do it; the ‘S’ runlevel is intended for use by the UserLinux (Debian)system.
A note of caution is warranted here. You can easily use the telinit command to reboot (run level 6), or shutdown (run level 0) the system, but it is not recommended. Certain programs need special processing for an orderly shutdown. Bypassing the expected shutdown sequence can have dire effects on your data. Older _Unix_ systems are especially sensitive to shutdown/bootup operations
The preferred method for a serious runlevel change is ‘shutdown‘. There are easier mnemonics, but in a running system they all point to the ‘shutdown‘ command. You can use the ‘halt‘, or ‘poweroff‘ command to stop a system and the ‘reboot‘ command to restart your system. In each case they call the ‘shutdown‘ command with different parameters.
In a single system (non-networked, or no locally shared resources) environment, the shutdown choice is pretty much yours. However, in a multi-user production system the rule of thumb is learn the shutdown command. The two most basic uses of the ‘shutdown’ command are for halting, or rebooting. The important parameter to know for shutdown is WHEN is the action going to occur. Here is the command synopsis from the shutdown man page:
/sbin/shutdown [-t sec] [-arkhncfFHP] time [warning-message]
The vast majority of your shutdowns will follow one of these two forms:
shutdown -h now
or to reboot instead of halt:
shutdown -r now
Intuitively, the arguments mean ‘halt‘ and ‘reboot‘, respectively.
In a multi-user system like a file server, the most important parameter is ‘time’. The time can be an actual clock time in the form of HH:MM, or a Julian style shutdown X minutes from now, denoted by the +X syntax. Note that the ‘+’ is needed. The keyword ‘now‘ is synonymous with ‘+0′. Here are two examples using the time parameter:
shutdown -h 16:30 shutdown -r +10
Another important point to remember: once the shutdown command is issued, a notice is sent to all the users of the system and no further logins are allowed. For example, if you need to bring the system down at midnight, don’t issue the shutdown command at noon and leave to take a nap. No new users will be able to login for the next 12 hours.
A good admin never takes a system down without warning the user community, but the shutdown notice is only sent after the command is executed! Fortunately, there are two ways around the downtime notification dilemma. The first is the ‘motd’, Message Of The Day. The motd is a useful feature that is often overlooked. Using the motd is easy and you are urged to read the simple man page for details. The second method of notification is the -k option. Using -k will send the downtime notice to all the users, but will not actually start the shutdown sequence. There is an important limitation to the shutdown notification: the downtime message is only sent 15 minutes (or less) prior to the actual shutdown.
The warning-message parameter may be useful for…high maintenance users. I find that the default message is authoritative and simple enough to accomplish the task.
Troubleshooting in Run Levels
Here is a tip contributed by Nicholas Petreley. Sometimes you may not want all the programs in a run level to execute. In this situation an easy way to disable a program is to rename it with the initial S, or K in lowercase. The system will ignore all programs that do not begin with a capital S, or K.
(UserLinux is a subset of Debian. Everywhere ‘UserLinux’ appears, you can substitute ‘Debian’ with equal facility.)
We are pleased to announce the immediate availability of CentOS-5.3 for the i386 and x86_64 Architectures.
CentOS-5.3 is based on the upstream release EL 5.3.0, and includes packages from all variants including Server and Client. All upstream repositories have been combined into one, to make it easier for end users to work with. And the option to further enable external repositories at install time is now available in the installer.
This is just an announcement email, not the release notes. The Release Notes for CentOS-5.3 can be found on-line at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.3 and everyone is encouraged to look through them once. Also worth browsing through at the CentOS FAQ’s at http://wiki.centos.org/FAQ
+++++++++++++++++++++++
ArtWork update:CentOS-5.3 brings in a completely new artwork stack. A big thanks to Alain Reguera Delgado, Ralph Angenendt, Marcus Moeller and everyone on the Artwork SIG for bringing us the best, most comprehensive artwork set yet. Also a big thanks to all the translation teams for their contributions to the installer artwork.
+++++++++++++++++++++++
Contrib repos are back:Given the widespread requests for user contributed packages directly being hosted within the centos repositories, the contribs repository is now back with CentOS-5.3. There are no packages yet, but over the next few weeks we hope to have a policy and process in place that allows users to submit and manage packages in the contrib repo.
+++++++++++++++++++++++
Upgrading from CentOS-5.2 ( or CentOS-5.0 / 5.1 ):If you are already running CentOS-5.2 or an older CentOS-5 distro, all you need to do is update your machine via yum by running :
‘yum update’
Running ‘yum list updates’ before doing the update is recommended, so you can get a list of packages that are going to be updated. To check you are indeed on CentOS-5.3, run : ‘rpm -q centos-release’ and that should return: ‘centos-release-5-3.el5.centos.1′
+++++++++++++++++++++++
Upgrading from CentOS-2.1 or CentOS-3.x or CentOS-4.x:The only recommended way to update from an earlier version of CentOS is to download and run a fresh install. In some cases, running the installer with the ‘upgradeany’ option might also achieve the desired results, however you are strongly recommended to look at the CentOS Wiki where hints and notes about potential upgrade paths from CentOS-4/3/2.1 to CentOS-5 are provided.
+++++++++++++++++++++++
Downloading CentOS-5.3 for new installs:When possible, consider using torrents to run the downloads. Not only does it help the community and keeps mirrors from running up high bandwidth bills, in most case you will find its also the fastest means to download the distro. There are present over a thousand people already seeding CentOS-5.3 and its possible to get upto 100mbps downloads via
these torrents.– Via BitTorrent :

Due to bandwidth considerations the CentOS Project does not publish ISOS directly from our network machines. However direct downloads are available from external mirrors over http, ftp and rsync, and a geoip based list is available at http://isoredirect.centos.org/centos/5/isos/ to give you the best predictable match ( and only lists mirrors that are
updated already, so you dont need to waste time looking for a sync’d mirror )Some mirrors also publish DVD images that can be downloaded directly. Refer to the mirrors list page at http://www.centos.org/mirrors for more details Mirrors that offer DVD’s are clearly marked on the page.

Thanks to the fact that Karanbir is now back in action, the QA team is now working on the 5.3 QA tree at full speed. There are some nice things in 5.3 (you can already look at the Upstream release notes). We’ve already discovered some missing deps and other new good things. Of course everything will be reported on the Wiki/in the CentOS 5.3 specific release notes.
One of the thing that astonished me is the fact that (even if not written in Upstream RN) some drivers seem to have been updated. For example the sky2 module didn’t support the Marvel gigabit 88E8056 nic since 5.1 .. but .. :
[arrfab@waldorf ~]$ modinfo /lib/modules/2.6.18-92.1.22.el5/kernel/drivers/net/sky2.ko |grep alias|wc -l
29
[arrfab@waldorf ~]$ modinfo /lib/modules/2.6.18-128.el5/kernel/drivers/net/sky2.ko |grep alias|wc -l
30
Interesting , isn’t it ? (especially for people having that kind of low-level entry nic in their workstation ..)
Other interesting stuff is the newer scsi-target-utils (aka tgtadm/iScsi target) that now includes a config file and two helpers to setup a new iscsi lun easily (tgt-setup-lun and tgt-admin) .. of course there are other new good things so stay tuned for more informations and of course, don’t forget to read the Release Notes when they’ll be published !
Big day for the Debian fans - Debian GNU/Linux 5.0 “Lenny” has been released: “The Debian Project is pleased to announce the official release of Debian GNU/Linux version 5.0 (code-named ‘Lenny’) after 22 months of constant development. Debian GNU/Linux is a free operating system which supports a total of twelve processor architectures and includes the KDE, GNOME, Xfce, and LXDE desktop environments. This release includes numerous updated software packages, such as the K Desktop Environment 3.5.10, an updated version of the GNOME desktop environment 2.22.2, the Xfce 4.4.2 desktop environment, LXDE 0.3.2.1, the GNUstep desktop 7.3, X.Org 7.3, OpenOffice.org 2.4.1, GIMP 2.4.7….” See the release announcement and release notes for a detailed description of the release.
As usual, a wide variety of installation media is available for free download from the project’s mirror sites. For new installations, the “netinst” method of installing the distribution is probably the easiest; get the “netinst” images for i386 and x86_64 architectures from here: debian-500-i386-netinst.iso (150MB, MD5,torrent), debian-500-amd64-netinst.iso (131MB, MD5, torrent).
