Are there equivalent on Open Source?
I bought two Dell R200 because they was extremely cheap.
My target is Open Source SAN with active/passive setup.
Now i was wondering what RAID-level I should go for.
I will use 1TB SATA-II disks.
1) RAID-1 in both servers and mirror each other with DRBD.
With this setup i have like double RAID-1 so i lose lots of disk space.
4 disks -> 1TB
2) No-raid at all and i will mirror data with DRBD.
4 disks -> 2TB
Then there is change to go for RAID-5. Theres enough space to put third disk in that case
3) RAID-5 in both servers. Mirrors data with DRBD.
6 disks -> 2TB but more performance.
But in every setup i lose space more then i would like to.
Actually i dont need space more then 1TB, but i would like to get best possible redundancy and most space available i could.
Also need to remember that those servers does not support hot-plug HDs so in case there is disk-failure i need to be able to shutdown one server and iSCSI should still be up and running.
Of course theres change to make it active/active.
I was thinking that if I go for the RAID-5 I will make LVM-VG on both nodes (san-vg1 and san-vg2) and use it 50/50.
In case of fail both VG's will be used from working node.
Im going to use Debian Lenny I guess..
I was looking for OpenFiler because of the GUI, but im familiar with Debian and have always done everything from cmd.
an A/V kind of solution, that allows me to use my own custom signatures, etc. just wondered if such a thing existed.

View 0 Replies View RelatedI have been getting multiple emails a month for a service which I have never purchased.
The information they have harvested off the internet (since I know where they found it) and have obtained solely for use in attempting to charge me is-
Invoiced To
Steven Crothers
12345 Main St.,
Detroit, MI, 48021
United States
Which is completely obvious that it is fake.
I respond to EVERY invoice with a cancelation request, yet the tickets that get opened in the WHMCS billing panel get deleted a day later, however I have tickets in there that I have opened by use of the ticket insertion form that have stayed - none of which were ever answered.
The latest ticket information-
Department:Billing And Invoicing
Date:09/10/2009 10:05
Subject:The Second Time...
Status:Open
Urgency:Medium
It's still open without a reply.
I have put tickets into their Kayako system as well (They have two support systems, I would assume its due to poor management of their company). One of which was answered, with simply the output of `uname -a` on some server somewhere with my name as the hostname.
I than have attempted to reach anyone via livechat at [url]they constantly tell me that I am not allowed to speak to anyone until I pay my bills up to current (now remember, I have NEVER ordered anything from them, they don't even have valid information on file). Just tonight I demanded that I required to speak to a billing agent or I would be pressing harrasment charges against them for the 23 emails I have recieved in 3 months from them trying to extort money from me. They than banned me from their LiveChat software.
I have no idea what to do at this point, they are just sending me bills every month. I mark it as spam, but its frustrating to have a company trying to extort money from me on a very regular basis.
What is the best open source web-based interface for system administration for Unix?
I found one named Webmin but I'm not sure if this is a stable project.
What open source in linux do you know for anti-spam & anti-virus? Is there existed a benchmark?

View 3 Replies View RelatedI own a small tech firm, mostly in business to support the customer with basic repair and upgrade. In recent year, more and more of my SMB customer ask me about the hosting service of the CRM or CMS.
The question I have is, although the open source tool, such as SugarCRM and Drupal is free of charge, but will it be free for some one like me to offer the service to my customer, either the same or customerize it a little bit.
And if it can be done, what kind of precaution I need to take, so I will not be involved in the copy right battle later on.
Thought this might be of interest to folks on WHT. We put together a solution using Nginx ( Engine-X ) to do Global Server Load Balancing. This solution lets you do GSLB without having to fork over $26k per site to F5 or Foundry.
Thought it would be of interest to both end-users as well as dedicated hosting providers who might want to make it into a service (eg. sell a dedicated host in Europe and the US as a group, with the solution pre-installed).
The entire project, including relavent configs is available for download in the latest ( issue 6 ) FREE issue of o3 magazine (o3magazine.com)
I want to set up a dedicated server for spam and virus filtering (MX)
But i was wondering, is there a good opensource based tool for this?
Do you have any recommendation for an open-source firewall running on Unix which could do:
- Filter and redirect incoming (with exception for some IP).
- Filter outgoing port (with exception for some local IP or MAC).
- Monitoring incoming traffic
- Monitoring outgoing traffic
- Block access from external to a list of IP
- Proxy authentification
- VPN configuration
I search for 2 days now and nothing seems to respond to these requirements. It's for a local network.
I signed up for a medium unix shared hosting account at Fluid Hosting tonight. As I did my research over the last several days, not just here, but elsewhere, I just couldn't find any serious complaints about them! Oh, there were a few, but they just seemed to be gripes from deadbeats. Over and over I was struck by how satisfied customers were.
So, even though their service plans may be a little skimpy and their fees a little higher, I just couldn't find any reason to throw them out and eventually they bubbled to the top.
OK, Fluid Hosting, don't prove me wrong!
I initiated a account cancellation on around 31st July through sending an email. In response I was advised to open a ticket by logging into the Control Panel I did it as requested. Till now account is not canceled and day before yesterday I got charged for another month. Actually thats the time I came to know that its still not canceled. Since then I am contacting FH HelpDesk and I am just getting the same reply "I have put a note to my manager" It's happening for two days now. Yesterday I was told my request will be closed by late evening and I will be given the refund...but no action.
Now I contacted them again, got the same reply "I have put a another note to my manager"
I know probably I am whining out my fustration but waiting for a month and then manager is "unable" to take a look at note by the support...not sure whats happening
To the full disclosure, I had signed up multiple times with FH (may be 6-8 times) in a year or two period and had canclled the account on differnet occasions (due to my busy schedules I am unable to maintain the site) and I have always got a fantastic service to say the least...but this time...
I want to let folks know about the uncommonly good experience I had working with Fluid Hosting and Dave Tong. I also want to thank the WHT users who suggested FH to me. I understand this is my first post and some may want proof that I'm not a shill. I'm happy to provide that verification.
I had made two very large mistakes in a row by choosing IPOWER initially, and IXWebHosting secondarily for my webhosting needs. I quickly discovered that 90% of IXWeb's support staff is offshore and really isn't particularly interested in fixing issues or even responding to Tickets in a timely manner.
It took over two weeks for them to diagnose the sporadic slowdowns my site was experiencing to an overloaded MySQL server. This poor server was barely able to stay available for more than 2 days at a time and was processing well over 1300 queries per second. And so, on Friday afternoon I called and asked what it would take to get my database moved to a new, less busy, DB server and my webserver pointed there. I was assured it would be a matter of hours.
Two days later, at 4AM, I contacted Dave at Fluid. He explained my options and I signed up. I was astonished to find competent tech/admin personnel manning a support chat at 4AM on a Sunday.
By 12:30PM that same day, my site was up and running. I simply cannot say enough about the level of service Dave provided, as well as the courtesy he showed me when I asked many stupid questions during the transition. I would recommend Fluid whole heartedly.

Which PHP encoder do you all suggest out of Ioncube and Source Guardian? Or possibly another if you know a good one. I checked out Zend Encoder, but its expensive as hell.
Currently I'm thinking about Ioncube. I know the majority of web hosts have ioncube loader installed, but I'm not sure about source guardian.
when I compile lighttpd from source -- I cannot seem to enable/disable the modules I need.
I have tried
./configure --without-status --with-rewrite
and also
./configure --disable-status --enable-rewrite
but no luck. The rewrite flag may not work since the configure script may or may not detect the pcre library, but status should be disabled.
After the configure script is complete, I get a listing of the enabled/disabled modules that are in the build and nothing new has been changed.
if a program is compiled and installed (configure -> make -> make install) with a --prefix pointing to an empty subfolder, then would removing it be just a simple delete the folder and it's contents action ($rm -fr subfolder/).
Ok so lets say I was to install php from source with a complile prefix flag set to /usr/local/php
Then all the binaries and configuration files are set within the directory (php/conf , php/bin). If I want to delete the php installation then I would just remove the /usr/local/php directory, No?
Thinking very seriously about revolutionizing the ISP market, starting with WiMax-based service in the Texas hill country, as I'm tired of the basic monopoly outside of town and the near-monopoly in town for halfway decent access. Anyhow, I plan to get Cogent FastE for the main backbone, however I know I need something else in case some spat starts between Cogent and someone else (Level3, France Telecom, Telia). Internap is in Austin I know, but Cogent has a POP in San Antonio which is much closer to where I'm going to deploy the network. Any options in the Internap price range for maybe 20 Mbit to start? Yeah, I know that the price of the "backup" connection may be more than that of the main line, but if people want their WoWwebetc. I want to live up to that promise.
Thanks in advance. If I gotta use Internap I'll do that, but again that means setting up a link in the opposite direction to what I'm thinking right now. The ultimate answer would be something relatively inexpensive (sub-$100 per Mbit with 20 Mbit commit) relatively close to one of Cogent's San Antonio data centers. Cogen't bandwidth deals are awesome, but with one peering argument per year or so a backup seems needed.
