Re: [CentOS] Air Conditioning - ON!
I understand how answering everyone's requests for progress updates can slow a development process, I've been on the development side of that before. I want a progress report as much as anyone I'm sure (and so does my boss), but, I'm not going to ask for it. I instead spend a little time, and do a bit of digging, and can find enough of an answer. I think though, I have had better luck finding progress information on CentOS than I did when I was waiting on upstream to release 6 (of course they had betas, and maybe I just didn't look in the right place, but I didn't find much status information). Committing to a product launch date, then trying to patch the product after the fact is IMHO a bad thing, and I'm glad upstream CentOS do not do this. I can think of some suggestions of my own to maybe help the development process and community involvement (as I'm sure a so can a great many people), but I will keep those to myself for now. Trying to change anything major now will only significantly slow things down. CentOS team, you have my understanding, and my appreciation for your hard work, and I look forward to being able to use the product of that work when it's ready. On 2/21/2011 1:21 PM, John Hinton wrote: All, (and please do not turn this into the next long thread) We have a small team which volunteers their time to create the CentOS releases. They are pounded right now with getting that done... it is as simple as that. Each of us 'chose' to use CentOS and with that choice comes nothing more. Why are we complaining? To me, it is all very self-centered. Basically we're all complaining because we 'want' something. And yes, I'm on edge wanting something as well... but that is life with RedHat in general. Some of the suggestions made: 1. Send money. OK, so using a very loose or reapplied definition of a word... we want to 'prostitute' the CentOS team. In other words, if we send money we have the 'right' to gripe and press for rapid releases? Demand services? 2. Add more staff. As a small business owner, the very last thing you want to do is add more staff when you are in a slammed state. It takes all of the 'productive' workers time to train the new staff and output slows to a crawl. 3. Make any other number of 'helpful' suggestions. Well, I think by now the CentOS team knows better than us how this needs to be done based on infrastructure and team members. And even if they aren't doing it right, we don't get to make demands that it be done differently as this is how they have decided to do it. Remember, you chose CentOS based on how they operate. You can go away if you like. 4. Bringing up other distros that are ahead of CentOS. This just an attempt at indirect pressure on the CentOS team to get a competition going. Only the team gets to choose their competition. CentOS 'rates' how it rates and that is up to the CentOS team and their decisions. Some cheerleading might be welcomed, as long as it doesn't become an I cheer for you therefore you owe me. 5. MOST IMPORTANT discussing this right now is the wrong time. The CentOS team needs to be focused on the builds. They need to 'feel good'. They do not need these distractions, complaints, suggestions, pressures and generally negative comments at this moment in time. If it really bothers you, save it for later and bring it up when things are back to normal loads. Perhaps some good will come out of it, but not now. I know that most mean well, but look inside of yourself and the rush is about something you want... and YOU chose a FREE distro, which just so happens to convert to the paid version very easily. 6,7,8,9 and 10 (fill in your own but keep them to yourself) If I were a member of the CentOS team right now, I'd likely be looking at the door. I positively would be needing to step back and take some time to myself to try to cool off and feel positive about what I'm doing. To me and from what I have heard from the CentOS team, very little of what is being said on the list is helping but instead is counterproductive at the moment. Obviously the team is 'reading' the list and 'obviously' some of us have pushed them further at a very high stress time, than they have ever been pushed before. You may also note that upstream was also 'very late' with these new releases. Could it be we are discovering why? (please don't try to answer that) Please please please... ease up, give them the time they need. Make notes for future conversations, but quit distracting them and making them feel bad. Or, write your scathing reply to a thread... get really down angry and in the dirt... then when you're done, just delete it. CentOS team, I do have just one suggestion (and I have no rights to ask this).

How about BugforbugIdenticaldebreandingrebrandingofupstreamenterpriselinuxOS? Only joking. I take your point, but the critical fixes being held up for a dot release isn't really very Enterprise friendly either. I think it fair to say that CentOS is not suitable for the enterprise unless the servers are non-public, on a secure network and the risk of internal hacking is low. That is just an unfortunate nature of a rebuild project but it does make the release time a sensitive matter. Karanbir tweeted during FOSDEM that the Belgian police use CentOS. As everyone who is paying attention knows that any exploit that RedHat has released an updated package for post is 5.6 is sat waiting to be exploited on those police servers because it won't make the CentOS repositories until 5.6 is out. I wonder if the Belgian police know that.

As everyone who is paying attention knows that any exploit that RedHat has released an updated package for post is 5.6 is sat waiting to be exploited on those police servers because it won't make the CentOS repositories until 5.6 is out.

[CentOS] how to optimize CentOS XEN dom0?
Hi,
I have a problematic CentOS XEN server and hope someone could point me
in the right direction to optimize it a bit.
The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can
take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD.
dom0 is set to 512MB limit with a few small XEM VM's running:

picturestravel6 255 1 -b 13.3
rafttheworld 7 255 1 -b 11.3
zafepres.vm8 511 1 -b 19.0
the server itself seems to eat up a lot of resources:

total used free sharedbuffers cached
Mem: 512472 39 0 13215
-/+ buffers/cache:244268
Swap: 4095 0 4095[/CODE]
Yet, it only has XEN, Webmin (since it's a CloudMin XEN server), Exim,
Apache and a few other services running:

Is there anything I can optimize on such a server?

Remember, Linux uses a memory full model, so although it appears that there is 39MB of real memory available, there is actually 268, with most of that being used to cache filesystem data. If you want to see how loaded a system is, with respect to memory pressure, try using 'vmstat' and look for how often it is swapping pages into and out of swap. Also, have a look at the Xen users guide. It has some performance-enhancing tips that you should be aware of. In particular, realise that dom0 is a little special, particularly with regard to IO. Is there anything I can optimize on such a server? Not entirely sure what you need to optimise at this point. So far I see a reasonably normal-looking system (although, to be frank, I don't have a lot of experience with Xen at present).

[CentOS] security cameras
I heard about some inexpensive security cameras which get their power through the same cat5 cable which delivers the data/pictures (which would simplify wiring tremendously).

TCP/IP cameras would work with any OS, most just FTP or whatever the pictures to a webserver you provide, or they run their own server and you can wget the pics off them. but I've never seen any IP cameras I'd call really cheap.

Hi. I am trying to configure sendmail that is looks up the users credentials to allow them to send email via that server via an imap server on the same machine when sending email while on the road. I can send email when specifying a user that is stored in the servers /etc/shadow ... no problem but I cannot get my head around it how to do make saslauth OR sendmail lookup the user creds via the imap daemon. This is the working config (mc) for the sendmail daemon when using a locally created user (I knock the PLAIN off once I got it to work): define(`confAUTH_MECHANISMS', `LOGIN PLAIN DIGEST-MD5 CRAM-MD5')dnl TRUST_AUTH_MECH(`LOGIN PLAIN DIGEST-MD5 CRAM-MD5')dnl DAEMON_OPTIONS(`Family=inet, Port=465, Name=MTA-SSL, M=s')dnl etc. How can I make sendmail (or saslauth) to get the user credentials via an imap server running on the same machine (the credentials are from an internal samba server) so I do not need to enter users details twice?

Re: [CentOS] how to optimize CentOS XEN dom0?
you should have a look at your I/O disk status. try with iostat -dx 5 to see the disk utilization info over time. when it comes to slowdown on a virtual environment on a Desktop grade machine, i suspect disk I/O latency and bottleneck as a cause. check that your disk is running at its optimal state. look at some indicators , such the the I/O utilization averages, server load averages hddtemp /dev/sda will check for heating ( under high load it might ) in any case , you still got plenty of ram to spend.

Re: [CentOS] how to optimize CentOS XEN dom0?
The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD. dom0 is set to 512MB limit with a few small XEM VM's running: root@zaxen01:[~]$ xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 512 4 r- 96.5 actionco.vm3 1519 1 -b 14.8 byracers.vm4 511 1 -b 85.7 ns15 511 1 -b 22.3 picturestravel6 255 1 -b 13.3 rafttheworld 7 255 1 -b 11.3 zafepres.vm8 511 1 -b 19.0 ... What are the actual symptoms you are seeing? In general I found that tuning the disk scheduler and also the Xen guest scheduler to be helpful: http://wiki.xensource.com/xenwiki/CreditScheduler http://www.cyberciti.biz/faq/linux-change-io-scheduler-for-harddisk/ Also, I always recommend building Xen servers to use SAS drives rather than SATA because SATA are half duplex while SAS is full duplex, meaning under higher or more random IO you will better throughput. In my experience I see almost double the performance when using SAS over SATA, but our environments are IO heavy and may not reflect the realities of your environment. I would also suggest, running disk IO stats in the VMs simultaneously while running iostat or vmstat in Dom0 to get a good read for where bottlenecks really are. I actually prefer to use the simple postmark utility as it is relatively simple and avoids disk caching issues which skew your results. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
