Re: [SLUG] Virtualisation and DRBD
While the setup you describe is possible there are a number of drawbacks: - DRBD disks are very slow, depending on the protocol you set them to use but still there is a performance penalty. If you DRBD the entire image of a running xen guest, your going to suffer performance hits for everything the OS does - not just the HA important data - Live migration is fantastic but you lose the ability to independently upgrade either side of the cluster. This makes rollback harder and more complex - Likewise, you kinda put all your HA eggs into one basket since this one DRBD setup might be the basis for a number of clusters. Can create some complex failure scenarios, and be hard to maintain e.g. should you wish to resize the DRBD disk maybe - Finally you now make a decision and describe the VM's themselves as cluster resources, or you have clusters on-top of clusters and have a dom0 cluster and domU cluster. For these reasons I would lean towards running DRBD inside each VM, with a minimum amount of shared state of the disk Joel On Wed, Aug 25, 2010 at 12:46 PM, Nigel Allen d...@edrs.com.au wrote: Hi All We're investigating both virtualisation of servers and High Availability at the same time. Currently looking at Linux-HA and DRBD (amongst others). The idea of DRBD appeals to both me and the client as it means (or seems to at least) that we could add a third (off-site) machine into the equation for real DR. What happens when we then introduce Virtualisation into the equation (currently have 4 x servers running Centos Windoze Server - looking at virtualising them onto one single box running Centos-5). I suppose the (first) question is: If we run 4 virtualised servers (B, C, D, and E) on our working server A (complete with it's own storage), can we also use DRBD to sync the entire box and dice onto server A1 (containing servers B1, C1, D1, and E1) or do we have to sync them all separately? Will this idea even float? Can we achieve seamless failover with this. If not, how would you do it Any input (as ever) gratefully accepted.

Re: [SLUG] A little script help
Hi Josh,
Having such strict rules about your passwords obviously reduces the
keyspace and makes them far less secure. Also for the really paranoid
$RANDOM in bash is a pseudo-random number generator that could
possibly be predicted - you should use a more secure random source.
Here is my attempt at the script you are looking for. I'm guessing you
wanted the middle of the password to be lower-case only? Anyway
shouldn't be too hard to modify if this is not what your after.
#!/bin/bash
ULENGTH=1 # number of upper-case letters
LLENGTH=5 # number of lower-case letters
NUMLENGTH=2 # number of numbers
ULETTERS=ABCDEFGHIJKLMNOPQRSTUVWXYZ
LLETTERS=abcdefghijklmnopqrstuvwxyz
NUMBERS=123456789
for (( i=0; i$ULENGTH; i++ ))
do
PASS=$PASS${ULETTERS:$(($RANDOM%${#ULETTERS})):1}
done
for (( i=0; i$LLENGTH; i++ ))
do
PASS=$PASS${LLETTERS:$(($RANDOM%${#LLETTERS})):1}
done
for (( i=0; i$NUMLENGTH; i++ ))
do
PASS=$PASS${NUMBERS:$(($RANDOM%${#NUMBERS})):1}
done
echo $PASS
exit

This solution is strange because - you may hit issues because not all FS locking commands will be supported - running multiple database instances connecting to the same DB files is normally done in an Oracle RAC configuration. You don't run Oracle on the app servers you run it on database servers and use a shared filesystem like ASM or OCFS2 normally connected to the DB files over a SAN. Network filesystems are not normally used for database files. Is there a good reason you need more than one oracle instance?

[SLUG] Merging two physical directories using possibly using ln-s and simple moving question
Slug, Two embarassingly simple questions. First, I have two directories with music files. I want to have them appear as one directory to the filesystem, but actually be in two physical locations (its too large for one disk). so I have /home/media/music/ and /misc/media/music/ and I want all the directories in /misc/media/music to appear in /home/media/music. I thought one way would be to recursively ln-s the directories, and then cron this operation. I am thinking there is a better way though. What are your thoughts? Second question: back in my windows days I would use the GUI to do tasks like grab all the files created yesterday and move to this directory. In a linux terminal I can't work out an easy way to do this. One way is find -ctime 1 | xargs mv But that is very inefficient, and not particularly easy to type or remember. Another way is to open norton commander or a variant and use that, but call me crazy I still reckon this task and other similar tasks are just easier with a GUI.

Hi Joel: I have read the manual and also found the config file to modify. I have some questions see below under [Louis]. Anyone else, feel free to answer them as well. [Louis] My objective here is first to have AWStats stop counting hits fron cron jobs. For each web site on the server, do I enter the IP address of the server itself in each site AWStats config file or do I enter the IP address of the site hostname in SkipHosts in each site AWStats config file? If cron is running on localhost, you enter localhost. [Louis] Most of the hits from the Hosts (Top 10) section of AWStats is from my ISP as a result of the activities I do regularly on the server. I don't want AWStats to look at my ISP IP period. The ISP IP is dynamically allocated. So do I just enter say the top 2 level only, i.e xxx.xxx.ignore.ignore Where xxx.xxx is the part I enter ? You enter ^xxx.xxx. as in the example directly above SkipHosts. [Louis] I have other questions from AWStats log display. With the Connect to site from section of AWStats: 1. the part Links from an Internet Search Engine, the data is provided in two parts, i.e - engine Pages/Hits 1.1- What does Hits mean here ? Does it mean the no. of times Search Engine spidered the site ? I think hits is files, number of things accessed. So if your webpage has an external stylesheet, or some external javascript, the spider may grab these. Google may even get the images for its image search. 1.2- What does pages viewed means here ? Does it mean total pages that the Search Engine spidered on the site ? It means the number of pages viewed, the number of .php, .html, .htm, etc. files accessed I guess. 2. the part Links from an external page, sometimes I see pages from the site itself listed in this section. How can that be ? Not sure, that is a bit perplexing. Do they have the same hostname? Make sure your HostAliases is set up correctly if you have missed a host here that your site could be called then it will think its external. Thanks. No worries hope that helps.

There is an option called SkipHosts which can be used to skip them. [Louis] I see. What conf file do I have to modify ? For SkipHost I just enter the full IP address of the server ? Also can I use this SkipHost so that when I connect to the site from my dial up ISP AWStats won't log these hits ? http://awstats.sourceforge.net/docs/index.html This explains where the config file should be and what it is called. I don't mean to shrug off your question but you are honestly better off reading the official manual for this. I will only explain it more poorly. Have a look at the documentation in the conf file and on the website about SkipHosts. You should not need to enter the full IP of the server because it will only access itself through localhost. To ignore all hits from your ISP you may need to ignore everyone going through your ISP which may or may not be a good idea. If you are on a major ISP then your reporting may become skewed.

RE: [SLUG] Questions about AWStats Logs !!
Issue 1: First let start with Unique Visitor. From my understanding a unique visitor is a host that came to a web site. A unique visitor can have more than one visits, and a visit can consist of more than 1 page viewed. Not let's say I connect to the internet using my ISP that uses dynamic IP addressing. If I go to my own main url site (i.e the base index.html) will AWStats count this as a Unique Visitor if the IP address changes from each connection despite the fact that I visted the site myself ? A unique visitor is one IP address accessing your website in one day, I think. If you have a dynamic IP and you visit your website you will be counted as one visitor for that day, unless you IP address is reallocated during the day and you visit again. Most dynamic IPs I have experienced do not change that frequently. Telstra cable - around 3 months. When I had dyamic ADSL - around a week with the one IP. Also I don't know about your network setup, if you are hosting at home its most likely all the connections would be local connections. For such a visit does this unique visitor falls in the category Direct address / Bookmarks from AWStats Connect to site from ? If so then does Direct address / Bookmarks means I'm the one visited the site, i.e if most of the hits are from hosts that resolves to my ISP domain name provider ? There is a HTTP field called referrer in which the browser provides the URL of a website that has linked to your website. If the referrer is empty then it is a direct address / bookmark. That means the user has typed it in or selected a bookmark. Otherwise they have followed a link. If the majority of hits resolve to you, chances are you have been the major viewer of your website yes. Direct address / Bookmarks does not imply you though as your friends may have bookmarked your website. Issue 2: = If I connect to my site via ftp or SSH is this also logged as Unique Visitor ? Does uploads and downloads counts as visits ? Awstats is just a program processing error_log and access_log. This is only connected to httpd. You can set it up to log mail and ftp but this is done separately with a different conf file. Issue 3: = AWStats has a section called Authenticated users (Top 10). What falls in the category Other logins (and/or anonymous users) ? Sorry not sure, I would guess it would be the logins that don't make the top 10 or the anonymous log ins? Issue 4: == Cron scripts that accesses web pages not via browser but command line. Does AWStats count stats for this as hits and logged them as Unique Visitors for host that resolve to the domain name where the cron is executed ? By default they are included. There is an option called SkipHosts which can be used to skip them. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
[SLUG] apt-get Older versions of redhat (freshrpms question)
Slug, I was going to upgrade my redhat 7.2 system to redhat 9 because I was under the impression that no more rpms were being built this version of redhat (as it says on http://valhalla.freshrpms.net/ ). Then with all the ssh stuff I ran apt-get update apt-get upgrade and it found new ssh packages and installed them! I am only interested in updating the system so it doesn't get r00ted, does anyone know what the deal is whether security packages are still being built and for how much longer? Do I need to upgrade or should I just keep checking the freshrpms website to see if they have stopped building packages for my system?

RE: [SLUG] Anyone Installed AWStats on a Server
Hi Sluggers: I'm trying to install AWStats onto my web server. However I am stuck with the setup/install instructions. It asks me to install all scripts on the server's cgi-bin, where is that located for root ? It has nothing to do with root per se. Your webserver runs under a user a separate user account normally, mine runs under apache group apache. Some run under www-data group www-data, some nobody group nobody. cgi-bin for me is located in /var/www/cgi-bin/ . It depends on your OS. try locate cgi-bin (damn cryptic linux commands ;-) That is where you install it. It also asks me to install some other files in a directory readable by web server. Again does root have a directory that I can access via web ? Forget root. Find out what user your webserver is running under. locate http.conf then go less on that file and check it out. Then just make sure that user has read access to the directory you put the files. Its not a big issue generally most directories are created with read access. joelh [01:04:32] joelh $ ls -dl /var/www/cgi-bin/ drwxr-xr-x 11 root root 4096 Sep 7 00:00 /var/www/cgi-bin/ Mine is owned by root but has read access by all.

[SLUG] Processing files with spaces
Hello Sluggers! I am often moving or coping files with spaces in them. What I would really like is be able to get just go | xargs mv %1 /newdir or something similar. At the moment I am stuck writing scripts like this #!/bin/bash IFS=' ' for f in `/bin/ls | grep -i $1` do mv -v $f $2 done What I would like is a general solution where I can say execute this command on every line in this file. Should I extend this script so it takes in the mv -v script on command line and works off standard input or is there an easier/better way? Surely this is a simple problem but I can't see the simple solution. :-( Joel -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
[SLUG] apt-get on Redhat
Thanks to Luke's advice I have installed apt-get and synaptic and after a few hitches everything is running very smoothly I love it. Just a quick question, I'm running redhat 7.2 will upgrades only be available as long as redhat keeps releasing them or are they built by users? Is there any pressing reason why I should upgrade considering I have a slowish system (433 celeron) and I do not want any extra bloat. Once again thanks Luke loving it!

[SLUG] RE: IMAP and procmail (Regular Expression Question)
* ^((List-Id|X-(Mailing-)?List):(.*[]\/[^]*)) My understanding of this regular expression. Indulge me: Message must begin with either List-Id or X-(Mailing-)List where the Mailing- part is optional. It must then be followed by a colon then anything up to a / then anything up to another So help me out a bit, I copied the line from Slug into a file and egrep did not match slug's List-Id line!

Re: [SLUG] PHP MySQL help
I use CURRENT_TIMESTAMP with DATETIME as the column type.
Thus just modify s/time()/CURRENT_TIMESTAMP/ should fix your woes.

I've got a MySQL question for you.
Is the php value ?echo time();? suitable for a MySQL timestamp field?
The reason I ask is because I'm getting an odd result in my web content
publishing site.
I'm grabbing form data from a query string and inserting it into MySQL.
(NewsDate is a MySQL timestamp field)
$query = INSERT INTO News(Headline, Story, Status, Author,
NewsDate) VALUES(' . $_GET['Headline'] . ', ' .
$_GET['Story'] . ', ' .
$_GET['Status'] . ', ' . $_GET['Author'] . ', ' . time() . ');
This query works fine, but when I view the information on my
news page the
date returned ($row-NewsDate) is:
00
Which formatted with this function ?echo date(h:i d M Y,
$row-NewsDate);? returns:
11:00 01 Jan 1970
If I leave the time() function out of my insert statement then
the returned
value is:
20030320084636 or (02:14 19 Jan 2038)
Does anyone know what is going on here?
Any help, much appreciated.
