Re: Fwd: XenServer is enterprise-ready and free.
And still - I now use Xen 3.0.3-80 on CentOS 5.3 as Dom0 and wonder whether this product will give me something better. I love open software and rather use it (and rather very much use supported versions from CentOS), but still wonder what do I give up by not using this product. 2009/6/26 Oron Peled o...@actcom.co.il: On 26.06.2009 Amos Shapira wrote: I just received a promotion for Free XenServer through חופשי זה יותר מחינם And to the Hebrew-challenged -- Libre is more than gratis. -- Oron Peled Voice: +972-4-8228492 o...@actcom.co.il http://users.actcom.co.il/~oron I love deadlines, especially the whooshing sound they make as they go by. -- Douglas Adams ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: is virtual ip is up
use ip a to get more detailed stuff about your network config. see man ip. 2009/6/24 Biran, Yahav (Yahav) yahav.bi...@gmail.com: im running multiply IPs on the same host. for each IP i wish to start an instance of httpd server. therefore i would liek to make sure that the VIP is up and running before the httpd is starting up. i tried using the /sbin/ifconfig and it doesn't give a full indication on the availbilty of the IP. i also tried to ping this IP but it is not clear if this ip is running from the same host. is there any way to distinguesh what IPs are running on a particualr host, and if this IP is vaild on the network before starting any service on this IP. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: High availability virtual ip
2009/6/24 Michael Tewner tew...@gmail.com: Hi all - If all you want to do is float an IP, Linux-HA will work, but a simpler solution could be, say, keepalived and vrrpd. Doesn't vrrpd require cooperation from the switch? I you would like to also manage cluster resources, Linux-HA is your best solution. I would agree that it has a steep learning curve, and it's a pain, but it does exactly what you want, and more. It will handle all of your cluster resources - We've used it for MySQL, DRBD, OCFS2, Asterisk, and others. I've been using Linux-HA for about 18 months now. Using the packages bundled with CentOS 5 (started at 5.0 and at 5.3 now). Although the packages are version 2, I couldn't get the fancier version 2 xml style configuration to work, it just kept crashing one of the daemons. So I stick to the older haresources style and it works, but I'm always suspicious about how well it'll behave in real tight corners. I have a suspicion that I can learn a lot more and gain more in regards to redundancy and fail-over but try as I might, after a few weeks of fiddling with the more fancy configuration format even just to serve a simple VIP I had to go back to haresources. This was over a year ago so maybe it improved since? What about RedHat Cluster Suite? It's part of CentOS as well, as far as I'm aware, it's based on Linux-HA, and a worker of mine has good experience with it so I'm thinking of maybe checking it when we have some time to breath again. Does it do anything better? --Amos ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: Linux-HA [Was: High availability virtual ip]
2009/6/24 Oleg Goldshmidt p...@goldshmidt.org: 3) Allow me to take the claims of too steep learning curve with a grain of salt. The last time I recall (a year, maybe less, ago) it took a *competent* person a few hours from never heard of Linux-HA to reading the docs, installing and configuring it, integrating it with a very non-trivial server application, verifying in the lab, demoing live that it works, and being very satisfied the experience. This included IP address HA, uninterrupted client sessions through failover, live replication of configuration changes, contiguous real-time management of a complicated network infrastructure through failover, etc. I wonder - was it with the more advanced stuff or the simpler haresources? haresources is indeed trivial, the other thing just didn't work (CentOS 5, x86_64, xen 3.0.x guests, doing VIP for the simplest test case but haresources is used in production for drbd, databases, http servers, vip's, LVS, monitoring stuff (collectd, monit), and home-grown software). If you have a pointer to GOOD documentation/tutorial about the cib and friends then I'd love to see it.

voip problems
Hi. I am abroad and using voip to call my family and other israeli phones. I use my cell phone as a sip client and connect via wifi to my asterisk box which connects to an ht488 (fxo) which is connected to a bezeq line. Until a few days ago everything worked great. However, in the last days, whenever i try to call phones i get an address busy error. Note that i am able to connect to the voicemail on the asterisk box. I tried to restart both my asterisk and my ata, but the problem remains. Any idea ?

[HAIFUX Lecture] KSM and the art of memory mangement - Izik Eidus
On Monday, June 29th at 18:30, Haifux will gather to hear Izik Eidus speaking about KSM and the art of memory mangement KSM is a linux driver that allows dynamically sharing identical memory pages between one or more processes. Unlike traditional page sharing that is made at the allocation of the memory, ksm do it dynamically after the memory was created. Memory is periodically scanned; identical pages are identified and merged. The sharing is unnoticeable by the process that use this memory. (the shared pages are marked as readonly, and in case of write do_wp_page() take care to create new copy of the page). = We meet in Taub building, room 6.

reshet.ynet.co.il not on Download Helper, anything else?
Hi, Does anyone know how to download the streams available on http://reshet.ynet.co.il? I'd like to watch them on my own time. They play well as a stream on my Ubuntu 9.04 but there are long programs I can't always watch in one go and I'd like to save the re-downloading (have capped Internet plan, very slow from long distance).

Hi Amos, I haven't done anything special and I am able to see all the movies :) Not sure what I have installed if anything, but I just click Play on Ubuntu 9.04 with FF3.5 (I am pretty sure its not related to FF3.5) and it works.
