[SLUG] Re: [LINK] Is SLUG down?
Hi everyone, Some of the root nameservers in the US were the victims of some sort of attack the past 48 hours. This is causing several DNS caches around the world to become polluted and all sorts of name/addr problems are arising as a result. For example some well known DNS names are not visible at my workplace (via AARNET) but are perfectly visible via my ISP. I suspect some people are getting the names and others are not. The Internet is a wonderful, fickle and fragile thing. rachel -- Rachel Polanskis Kingswood, Greater Western Sydney, Australia [EMAIL PROTECTED]http://www.zeta.org.au/~grove/grove.html "They who would give up an essential liberty for temporary security, deserve neither liberty or security" - Benjamin Franklin, 1759 -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Help with RHL-6.2 & IBM x340 "eserver"
Hi Sluggers, I am trying to install an IBM eserver x330/x340 with the ServerRAID driver. I am having problems putting together a driver disk for Redhat 6.2, in spite of having "support" for the machine. I built a kickstart floppy but I do not have the drivers installed correctly (I think). The problem is, I followed some guides on the net, to modify the boot floppy initrd.img file. I added the drivers I needed, edited modinfo and pcitable and repacked the .img file. When I boot off this floppy, the ramdisk loads Ok, but I cannot seem to get the drivers to load - I get a message: "trying to insmod ips.o (Path is NULL)" or similar. I suspect it is something to do with the way I have recreated the ramdisk image. What I am asking is: 1) can someone please point me to the correct way to build a boot floppy/initrd.img file? Yes, I read the kickstart Howto, and pursued the cpio commands but I think there's something wrong with my cpio image. 2) can someone just send me a 6.2 Ramdisk initrd.img file that already has the ips.o and module for the Intel etherexpress pro 10/100 NIC? 3) a 6.2 boot floppy that will work with an x330/x340 server? - This message was sent using Endymion MailMan. http://www.endymion.com/products/mailman/ -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

[SLUG] Who looks after your stack?
Hi, Please help me with a debate Who looks after your stack of software - such as in a typical LAMP environment? I propose that in most cases, it's been the UNIX admins who put together the systems then install and basically configure the apps that make up the suite of apps that can be called an Information System such as a httpd, php/perl plus SSL/TLS and a databases such as Mysql or Postgres. Of course there are also support shared objects and so on to consider as well. They maintain all this when there is an upgrade required or if a new feature needs to be added. How are you all doing this? Do you build the system and give it away to the web developers so they can download nasty binaries that may or may not integrate well together, or do they get a system that has the httpd and so on locally compiled with site specific options? Or do you give the Oracle DBA's your Postgres or Mysql to install, grant and deploy apps in, with the web devs only doing PHP scripts and similar? Or have you got a UNIX systems programmer who designs the archictecture, build standard and methods to compile the binaries and localise them and looks after periodic code refreshes each time PHP gets another cross-site vulnerability or if mod_auth_ldap needs the mem cache option and so on? Where do you draw the line? - Who looks after the httpd.conf and who looks after the httpd and who looks after it's compilation? Who looks after your stack? Inquiring minds want to know.

But now I want to have a Second directory under the first, that I want to reset all the directives for: AllowOverride AuthConfig And there is a .htaccess & .htpasswd file in this second sub directory. When we take the Satisify directive out of the first Dir, the second then presents with the passwd popup as required. Can anyone please explain how to reset the directives for a sub directory.

Hi, I am doing N+1 horizontal scaling on Solaris blades. It is the same principle. We use it as a webfarm to serve vhosts via a single instance of apache stack installed onto a NAS and shared across all the blades. All the blades share the same configuration and data from the NAS. The logs are written to locally on each blade. This lowers admin overhead as the AMP stack can be locked away read only and a vhosts.conf setup on the writable portions of the NAS to edited and maintained. We use PHP session caching and PHP acceleration to assist in content handling. The concept is simple. Use the Content Switch to supply Virtual IPs for each farm. Then add CNAMES to each VIP that you have. The CNAME represents an Apache Name Virtual Host and is addressed as such. There is no limit practically to how many VIP and CNAME clusters you can serve this way. Limitation is SSL, so we do termination on the Content switch - no SSL required on the blades but you need to have a VIP per SSL instance. This can also run shibbolised environments, tomcats, java stacks, mod_perl, PHP etc. -- Rachel Polanskis Kingswood, Greater Western Sydney, Australia gr...@zeta.org.auhttp://www.zeta.org.au/~grove/grove.html "The perversity of the Universe tends towards a maximum." - Finagle's Law-- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

This was for a company who will remain nameless who we "outsourced" monitoring to, who insisted on the above rather than using the shiny SunMC infrastructure we already had for the purpose. Porting this was a case of dependency, dependency.. Munin wants a lot of stuff - about 20 perl modules and then it wants RRDTool which in turn wants a whole bunch of obscure shared libraries such as cairo, pixman and pango, which is fine if you are a web 2.0 monkey, but in sysadmin world it is annoying. And then RRDtool wants you to have practically the latest of everything. And then it wants something called "pkgconfig" which is great if you are developer, but for sysadmin, very annoying.And then finally you can have the RRDtool perl module.. And then don't start me on some of the undocumented problems that caused gcc to break the compile because some stupid Linux hacker didn't understand POSIX compliance... So, in the end, I got the whole stack working.. My point. (oblinux) If you have an older, broken or improperly installed system, you will find Munin a pain to install. It wants practically the latest of everything, even touch libglib. If you have all your ducks in a row, it is still a pain but possible. Porting to Solaris 10 was easy for me, but if it had been a broken or older system, I doubt it would have got there. Munin looks OK, but it was obviously created by a bunch of anal-retentive module hackers with a mandate on making sure their install occcupies as much sysadmin brain power as possible. Approach only if you have a reasonably shiny system.. rachel -- Rachel Polanskis Kingswood, Greater Western Sydney, Australia gr...@zeta.org.au http://www.zeta.org.au/~grove/grove.html "The perversity of the Universe tends towards a maximum." - Finagle's Law -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Tuning Systems and Energy Use (Sys Admin Roles and Responsibilities)
Not many people are aware, but I was surprised, after discussing with some engineers a few years ago, that the physical vibrations of equipment in their racks can actually cause power increases and performance issues purely as a result of the vibrations interfering with disk seek times and so on. The sympathetic vibrations of the disk and media is actually perceptible when tests are run. As the vibrations are constant, this will affect the way the heads on the disk access the data. When the vibrations were suppressed, disk seeks improved commensurately and a noted decrease in power consumption and response time was noted. Multiply these factors when taking large SAN based media stores into consideration and then it is clear that careful setup of servers and storage in their racks can actually improve performance and reduce power loads a lot mre than you would expect And, so I do not appear to be coming from this angle as a Jonesian fact maker, here is some research to back it up! http://www.dbms2.com/2010/05/08/disk-vibration-data-warehouse-performance-problem/ It is just as amazing to me, as when an engineer demonstrated SCSI reflections by bending a cable beyond a certain limit, whereupon all data transmission ceased. Â The waveform of the electonic stream had a period that meant it could not "bend" around the pathway made by the cable and the data just stopped moving. Â Â Â I find things like this amazing because it is like observing some kinds of weird "quantum" behaviour you would not expect, manifesting in the physical world. rachel -- Rachel Polanskis Kingswood, Greater Western Sydney, Australia gr...@zeta.org.auhttp://www.zeta.org.au/~grove/grove.html "The perversity of the Universe tends towards a maximum." - Finagle's Law-- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] Enlightenment
On Thu, 9 May 2013, David Lyon wrote: I've had a similar experience. My Enlightenment (Bodhi Linux) notebook has O/S imploded with two weeks of continuous use. After changing themes, the file manager doesn't display anything (rendering problem?) making copying files from the SD card easily, not easy. Back to shell. Then, git for some reason has stopped being able to 'push'. Which is really frustrating considering that the only 'typing' and web-browsing, are the only function left to me that now work. I found the last time I used Enlightenment, many years ago, the best way was to compile it myself, from source. Never had problems with it then and was able to modify the components I found annoying and to optimise it for my particular platform. I even managed to get it to run on Solaris at one point. I doubt it would work that way these days - "portable UNIX" only applies to Linux flavours these days, not to the OS realm as a whole :/ rachel -- Rachel Polanskis Kingswood, Greater Western Sydney, Australia gr...@zeta.org.au http://www.zeta.org.au/~grove/grove.html The more an answer costs, the more respect it carries. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
