Hi, I am new to clustering and loadbalancing in apache, What is best way of doing it? How do I do the clustering and what tools do I need to use? Do I have those tools, I use CentOS , Do i have any tools in CenOs which comes default in it? And how do I do apache load balancing? should I rely on apache forums or mailing list or is there any way or tool I can use in CentOS? Can any throw some vague

Dear All, Currently we are running a mail system for 10000 users each 2GB mailbox. At present we have 5 mail servers where users mailboxes are distributed almost uniformly. We have a HP SAN Storage (HP EVA 6400) where mailboxes are stored. We partition the storage into five vg and each is mounted on the 5 servers. We are using postfix and dovecot. The system was running fine but currently we

At the moment I'm out of the office, but when I return I'll be certain to do that. Note that my solution is different from what you are working on with regexten, though I suspect some of the challenges that I've faced and overcome are not. I'm actually using UltraMonkey for load-balancing and failover of the Asterisk boxes, and my dialplan is set up so that it need not be changed

I'm a greenhorn when it comes to clustering in RHEL/CentOS and recently setup an active/standby clustering using Apache & Heartbeat. It seems to be a good entry step into clustering however after testing it I was disappointed in that the resource manager does not start httpd on node2 if httpd on node1 is dead (only starts httpd on node2 if the heartbeat daemon on node1 is dead). Is there

Hi Folks, I'm trying out some ideas for loadbalancing Samba servers with some replication underneath. Right now, we're trying to use DNS round robin, just to see if it works, but it isn't. Our basic config is that we have the same share and NMB server name on every node. Each node has a different IP hostname, which are all round-robin'ed to a single hostname. When we try to

Dear All, Today I'm trying to install CentOS 6 boot using text mode, but I can't create custom partition layout because I can't find the custom partition layout menu. Where is manually partition setup in text mode install? Please advice... -- -- Thanks& regards, David ------------------------ http://blog.pnyet.web.id

Hi Thomas, We need a load balancer to allow for a single URL "entry point" to multiple Icecast servers - we intend to host multiple Icecast servers behind the load balancer so that we can expand / contract capacity as required - we would add servers into the load balancer pool. This also allows us to scale beyond the number of listeners a single Icecast server can support, while still

Dear All, I just got a new server with the following specifications: motherboard : Intel S5500BC CPU : Xeon Quad Core 2.6Ghz RAM : 8GB HDD : 4 x 2TB SATA with configured raid 10 using raid embedded server. The problem is the centos installer can't detect raid virtual disk. I can't find any log error with the following error messages during installation process:

Hi Folks, I'm part of a Novell department that is working on moving from Novell NDPS printing to Samba printing. I have been told that the Samba environment will have to be clustered to assure the same level of redundancy for printing. Does anyone have any pointers? Whether actual experience in this or a location of good documentation of the clustering process? Thanks for

I saw this in the openfiler thread, and realised it is another major hole in my knowledge What do you all use for clustering, and does it run out-of-the-box with CentOS? My main areas of interest are : - DB clustering (PostgreSQL) - yeah, we're looking at commercial stuff and skytools - web server clustering - Apache on CentOS - storage clustering thanks, -Alan -- ?Don't eat anything

I'm setting up a mail server in an active/passive cluster. Does any know of a guide that details how to setup 2 linux servers connecting to the same data array? I'm planning on using heartbeat but I do not see any array configuration in the documentation. Thanks, Ed

Dear listers: Here I have a question on clustering methods available in R. I am trying to down-sampling the majority class in a classification problem on an imbalanced dataset. Since I don't want to lose information in the original dataset, I don't want to use naive down-sampling: I think using clustering on the majority class' side to select "representative" samples might

Hello All, I had problems with the security server, the server is frequently attacked using bruteforce attacks. Is there an application that can perform automatic blocking when there are failed login to the ports smtp, pop3 port, and others? I am currently using CentOS 5.5 in some servers Thanks in advanced....... -- -- Best regards, David http://blog.pnyet.web.id -------------- next part

Thanks to Anthony Ciarochi at Centeris for this solution. I have a Centos (Red Hat-based) server that is now accessible to AD users AND local users via ssh. I can control which AD groups can login using the syntax below. Red Hat-based distros use "pam_stack" in pam.d which is quite different than Debian's "include" based pam.d, cat /etc/pam.d/sshd #

Does anyone here on this list have experience with HA clustering? I'm previewing drbd as a potential tool, and wanted to know if anyone here has experiemented with it at all... How stable is it? Does the additional likelyhood of failure given the additional complexity actually get compensated by a better overall system? http://www.drbd.org/ Any feedback is welcome... -Ben --

Dear All, My servers running on CentOS 5.5 x86_64 with kernel 2.6.18.194.17.4.el gigabyte motherboard and 2 harddisks (seagate 500GB). My CentOS box configured RAID 1, yesterday and today I had the same problem on 2 servers with same configuration. See the following error messages for details: EXT3-fs: INFO: recovery required on readonly filesystem. EXT3-fs: write access will be enabled during

Dear all, I'm trying to obtain a fuzzy clustering with fanny from the cluster package, using a given set of data. That worked just fine. I have another separate sample of data from the same problem. For each case in this new sample I would like to know their membership coefficients with respect to the clustering obtained with the first dataset. In effect I want to have a kind of prediction

Dear All , For more process on data resulting clustering, one needs to access data within any cluster. How it is possible in CLARA? $clustering :gives us clustering vector as mixed, so it isn't as separate $clusinfo : gives us dissimilarities, Thanks a lot Amir --------------------------------- [[alternative HTML version deleted]]

Hi all, Can someone help me in creating a single bandwidth pipe out of two or more bandwidth providers. Say, I have 2 internet connections 1) 128 K 2) 128 K I want to use both of them on a single linux box. Is there any way to do so. Of course loadbalancing can be done, but I don''t want loadbalancing. I want to have a single pipe of 256 K. Some time back I was suggested to use squid on
