Cisco Cluster Management Suite (CMS) Software
Jul 25, 2008Is it easy enough to setup without using the SSH/Telnet console at all? I am thinking about purchasing a Cisco 3550 EMI
Is it free download/use?

If you are aware of any good hands on tutorials or docs than please feel free to let me know.
I dont mind if the documentation has no screenshoots but the technical explanations must be sound in order to understand how to configure RHCS.
Private Suite Price
Oct 24, 2009I would like to have a discussion.
We are looking for a private suite, and we have got many offers, can someone tell me what are normal prices per square meter in regular data centers? Just a basic room, no hardware etc.
We received really strange offers and they flip from 400 dollar to over thousand dollar per square meter.

Nov 9, 2014I am testing our Plesk linux-server (Plesk 12.0.18 on RHEL 6.6 x64) for SSL high security configuration with Qualys SSL Labs reccomendations (https://www.ssllabs.com/ssltest/).
Best choise today is using Elliptic Curves Ciphers Suite for secure-connection negotiating, but I could not force plesk-contributed sw-nginx to using elliptic curves ciphers suite (sw-nginx-1.6.0-1.14051516.rhel6.x86_64):
when place ssl_ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDH+AESGCM; to nginx server and vhost configurations, then secure negotiation is not established.
Starting from RHEL6.5 Red Hat contribute openssl with EC ciphers - https://access.redhat.com/documenta...erprise_Linux/6/html-single/6.5_Release_Notes (openssl-1.0.1e-30.el6_6.4.x86_64)
OpenSSL on live system shows these ciphers:
openssl ciphers -v | grep ECDHE
ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=RSA Enc=AESGCM(256) Mac=AEAD
ECDHE-ECDSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=ECDSA Enc=AESGCM(256) Mac=AEAD
I think, the problem is that the sw-nginx is compiled with old openssl binaries without elliptic curves support.Can Plesk development team recompille and release updated sw-nginx package..Сan use genuine nginx package from official nginx repository instead of sw-nginx package?

Ftp Cluster
Mar 19, 2008Anyone had any experience with setting up an ftp cluster? We have tried to search Google and haven't been successful in such a solution so I came here to ask if anyone else has ever thought about doing it. Or done it and how did you do it? I'm looking in to it for windows. 99% of my servers are windows.

Aug 8, 2007I see more and more hosts popping up (and older hosts switching to) offering what they call clustered load balanced plans. These plans are mostly on the low end price wise (sub $10/month), and the marketing speak tells of zero downtime, intelligent clustered, load balanced, failover, will wash your clothes approaches to keeping websites up 110% of the time.
I guess what I fail to grasp is are these plans really, truly load balanced clustered approaches, or is it more of a case of we have 1 DNS server, 1 mail server, 1 web server, 1 mysql server, and a backup server that in an emergency has rsyncs each hour to "failover" to and screw up your dynamic data?
If the webservers are load balanced, what about accounts that use SQLite db's, or berkeley db's, are these maintained 100% in synch, and if so, how? If one server goes down, and the other picks up the slack, won't the db's be out of synch and data contention will occur? Are sessions including SSL truly handled correctly?
Same for MySQL. Is this true two way replication with fault tolerant switchovers between master and slave to preclude data loss and corruption on hot switch overs when a server fails?
I guess I just see everyone slapping a "clustered" label on things, and speaking of load balancers, etc... all for the cup of coffee a month. But I am highly suspect if these plans are truly load balanced, or is it a band-aid approach to load balancing?
Just the ranting of a an older hosting owner who's just not sure what many companies are truly offering when they speak of clustered, load balanced, more uptime than Viagra type of solutions...
How To Cluster?
Mar 19, 2008We have been running two dedicated servers for a number of years now and we use Cpanel and DirectAdmin for the control panels. Today we had a big problem with our first server which effectively made the 150 sites on it out of action and it exposed a potential issue to us that if the server died that we'd have a big task restoring all the sites from the backup drive. I've heard that some hosting companies strip data across more than one machine and I presume this is a cluster, and I was wondering if this is the best method and what the most cost effective route would be to do it?

Jun 26, 2007I was wondering if there is any way to connect 40-50 Linux VPSes in a cluster. Most of the cluster solutions out there want you to recompile a custom kernel which cannot be done on a vps. The virtual machines are on different hardware nodes and I don't have access to those since I am renting the VPSes from another company.

View 3 Replies View RelatedDNS Cluster Pair
Jun 8, 2009On setting up a pair of CPanel DNS only servers, I decided to use 2 Virtual Servers from 2 seperate companies - one Xen and the other was Openvz. Reason behind it was in case something happens to the company or the virtualization technology implemented, I'm not screwed.
Guess what! Next day my Openvz node (I will not name the provider) went south and I'm on one leg right now. I'm kinda pleased with myself for having this laid out from the beginning and DNS is still working fine.
Now I'm thinking of having different OS - one linux and the other freebsd. Am I paranoid and over-the-top?
Mysql Cluster How To
Apr 2, 2008we are planing to build a 5 system mysql cluster for our website. i have few questions regarding this. As per our provider, we need mod_ndb for apache to connect database cluster. (SQL API). we have 5 system apache cluster.
Mod_ndb configuration, we need to add all table structure in http configuration. Is there any other way to connect database? or any other way to configure mod_ndb without adding table structure inside http configuration.
any other better way to connect database
MySQL Cluster?
Jun 1, 2008All my sites that depend on MySQL at iMountain have been down all day. I was in the process of converting some of them to Joomla/Drupal but I'm having second thoughts now.
My question is - shouldn't "clustering" prevent this sort of thing happening? I thought it implied some level of redundancy.
CPanel Cluster
May 13, 2008I try to keep on the up and up about hosting and constantly looking for a new host to provide better services, but I saw an article in TheWHIR that got me to wonder if people are making stuff up or is it just "marketing" or real?
Ok, so the article:
[url]
I hope adding a link to the article is ok?
First of all I have NEVER heard of cPanel ever offering clustered technology. Can anyone confirm or deny that this is real? I have really only used HSphere which I know has some cluster abilities and even those hosts don't advertise "clustered" services.
Then I see other so called cPanel wannabe clustered services which they call cPanel clustered failover or something like that which to me is ummm..more fault tolerant hosting than actual cluster hosting.
Basically, am I just not understanding the meaning of "cluster"?
I think cluster has to do with the proper allocation of reasources spread across the network of defined processes, though, I have been wrong in the past...

Some Feedback-Cluster
Sep 2, 2007I just need a bit of feedback, I currently have a forum, getting around 20-35k uniques per day.
I am currently on a Intel C2D, 4gb Ram, paying around $185/month.
Would setting up a cluster help me reduce the costs or load?

Which Cisco Firewall?
Aug 21, 2007We are looking to replace our existing WatchGuard Firebox's with a hopefully more reliable firewall from Cisco's range although I'm a bit lost when it comes to the different ranges.
Could somebody suggest a firewall that is capable of:
1: Both NAT & Drop-in (bridge) mode
2: Pretty low bandwidth requirements, no more than 10mbit/s traffic
3: SNMP Monitoring
4: High availability pairing
Cisco Routers
Mar 25, 2009I am on a tight budget for a Cisco firewall. I am browsing and seeing some affordable options in the x600 series.
Please tell me, which series is best?:
1600
2600
3600
The higher the better?..
Also what about submodels, like is 1650 better than 1600?
And how can I tell how much DRAM each one can take up to?
Cisco Guard
Apr 22, 2009I see a lot of DDos related articles here at WHT. We've got hit multiple times by DDos and had to handle those attacks everytime with a different approach.
The largest one and the most well know one (we were in Times Mag, AP news, CNN, slashdot, you name it - just do a search about us on WHT) was Russian botnet cyberattack - we had to anaylyze netflow and then block everything on our edge routers, then on the firewall and then locally on the servers.
Since then we had number of other attacks, some of them we were not able to defend on the server level, while, as you can understand we can't do netwflow and manual intervention evey time somebody gets an attach.
We have very good scripts which allow to mitigate huge number of DDos attack, whet our scripts are finding attacking IPs and blocking them automatically - still some attacks could be blocked only on the router level.
I've read that Cisco Guard (I am interesed in 65xx version of it) suppose to mitigate DDos attacks in automatic mode.
Cisco Redundancy
Sep 25, 2009after months of disruption moving servers into a new data centre, our once reliable colocation company has now had nearly 6 hours downtime in the last 16 hours. So much for network redundancy.

Which Cisco Router To Use
Jul 11, 2007I am currently looking at these Cisco switches:
- Cisco 2924 WS-C2924-XL-EN Enterprise Switch
- Cisco 2950 WS-C2950-24 Catalyst Switch
- Cisco 3512 WS-C3512-XL-EN Enterprise Switch
- Cisco 3524 WS-C3524-XL-EN Enterprise Switch
- Cisco 3548 WS-C3548-XL-EN Enterprise Switch
1) I was recommended to chose the XL-EN model switches because it seems they have more Memory, but the second one in the list (Catalyst) is not a XL-EN, is that going to have any affect performance wise? or it doesn't really matter?
2) I was also recommended to choose managed switches because that way I can use the SNMP features to measure bandwidth, are any of the switches above unmanaged?
3) I also want to be able to manage the switch remotely, web managed, are any of the switches above web-manageable?
4) Most importantly, when my datacenter give me a 100mbit drop, I dont know which port to plug it in in the 29** series. In the 35** I see it clearly but I am not able to see it in the 29**, any ideas?
5) On some of these switches I see a special port called "Console", what is it? where does that connect to?
6) Do any of the switches above not have a console port?
