Anti-Virus Recommendations

Apr 13, 2009

We have 2 servers, one running Windows 2003 Enterprise that hosts a ColdFusion app, and one running Windows 2003 Standard that hosts our SQL database that is used by the CF app. Nothing else runs on them.

Does anyone have any suggestions for anti-virus products that we could use on these? I don't want one of those elaborate and expensive "suite" programs. I just need to protect the boxes.

I use Kaspersky on our individual machines, and I really don't care much for Norton anymore.

Open Source Global Server Load Balancing

Aug 16, 2007

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)

Plesk 12.x / Linux :: Anti-virus Program That Can Be Installed On Version 12.0.18 As Extension Or Component?

Jan 14, 2015

"What anti-virus do you use on your postfix email server powered by Plesk?".Is there an anti-virus program that can be installed on Plesk version 12.0.18 as an extension or component? I need it primarily for protection of incoming email from malware.I've seen in Add or Remove Components in the Mail hosting features that I have installed Kaspersky antivirus, but I didn't seen anywhere that it actually can be configured from within Plesk. It also, as far as I can see, doesn't do anything. what is Kaspersky antivirus used for in Plesk and how can I configure it?

Linux Server-wide Anti-spam Solution

May 2, 2007

for a server-wide anti-spam solution I can implement on a Linux server. The mail queues are constantly getting backlogged with thousands of messages which bring the servers to a crawl. There are really two issues the solution needs to address.

1) Spam
2) Spam sent to other people that have the from address forged with our clients' email addresses.

We have spam assassin installed for individuals to use, but there's got to be some sort of solution that can clear out the vast majority of the junk before it even gets to the queue.

It probably goes without saying, but the solution needs to be open-source or have a very inexpensive license.

Open Source SAN

Apr 14, 2009

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.

Open Source Hosting Solutions

Oct 20, 2009

I 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.

Can I Host The Open Source Tool For My Customer

Jul 30, 2008

I 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.

Recommendation For An Open Source Firewall Running On Unix

Jun 11, 2008

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.

Anti-spam Solution

Jun 21, 2008

I am running Win2003 server with Plesk 8.3. Antivirus running is F-Prot. Me and my clients have been getting a lot of spam emails and I am looking for suggestions on how to stop them. Plesk seems to provide some options for checking blacklisted spam servers but I was not too satisfied with the result. Maybe I was not looking up the right urls?

So, any suggestions on blocking the spam would be welcome. I am ready to pay for it too...but I am on a very tight budget. A free solution would be the best for me at the moment.

I also used SpamAssasin for a time being but it did not work out to any of my client's satisfaction even after a month's "training" of SpamAssasin.

ASSP Anti-spam

Jun 14, 2008

I am interested in ASSP as a anti-spam tool and have heard good things, but I have 1 question I can't seem to find an answer too.

With ASSP is there a way to screen image spam like you can with FuzzyOCR? With ASSP do you even need to scan images at all? Because it waits for the sending server to respond for authentication?

I was running MailScanner / SpamAssasin / FuzzyOCR combo with a couple of chron jobs (to sweep fake bounce email out of the mail que for example) with very effective results, but it took forever to tweak all three to reduce server load. MailScanner was breaking webmail randomly so I have it disabled currently so I get a lot more spam.

Anti Spam Blocker Tool

Jul 25, 2009

I thought I should share this among all.

You will find many Anti spam blocker tools available in market. I recently come to know about[url]
. Itís an excellent tool to encrypt your email account if you use to display it on your website.

Generally, spammers uses robots (some kind of crawler) to get email accounts from websites. Once they get it they start selling it to other spammers and will start sending spoofing emails.

This tool will help you to encrypt your email address and stop spam coming from your website

Anti-spam Appliance - Barracuda, MailFoundry, Etc.

Jul 31, 2009

Does anyone have any experience to share concerning these devices?

I'm having some serious spam issues and would like to look into a better approach to preventing this than the typical SpamAssasin solution bundled with cPanel, Plesk and so on. SA seems rather inefficient, needs a lot of training, can get a lot of false positives, tends to break now and then, and so on.

Have any of you used either the Barracuda or the MailFoundry applicances, or even better - compared them first hand? Are there any similar solutions out there, perhaps cheaper/more cost effective in the long run?

$2000-3000+ for the hardware and around $500 a year for an anti-spam solution is a little steep in my opinion. Especially considering the old and cheap hardware for an example MailFoundry uses. How accurate they actually are in terms of false positives is also seemingly debated. MailFoundry promises a near 0 false positive rate, while some user-experiences suggest somewhere between 6-10% - which could represent an issue just as problematic as spam itself. Nobody wants to lose out on important email. To spend such an amount on a device and updates, it certainly needs to be worth it. Is it?

Are there any equally good or better software based solutions out there, that one could for an example use to set up a custom anti-spam server using existing hardware at the DC?
