Service Update: Email NDR’s (Non-Delivery Receipts)

With immediate effect, our Exchange and Linux mail hosting platforms will no longer send NDR’s (Non-Delivery Receipts) when email is sent to an invalid address. This is to reduce the number of NDR’s we’re sending out to the Internet as a result of spammers sending to invalid addresses (so called “Backscatter”). This change is due to the number of occassions our mail server IP addresses have ended up on Internet blacklists. Preventing this occuring stops legitimate customer email being “bounced” by remote sites, and/or us needing to send mail via alternative routes. Wikipedia has more information on Backscatter.

Windows Server 2003 End of Life is Coming Are You Ready?

As you may have heard, the planned EOL (end of life) for Microsoft Windows Server 2003 is around the corner. From July 14, 2015, if you run a Windows Server 2003 platform, it’ll no longer receive security updates. This has the potential of leaving your network open to zero-day viruses, or without support!

 

Note RM networks may be affected too! CC3 networks, and early adopters of RM’s CC4, may be running Windows Server 2003 as well. These servers will need replacement too, so it’s a great time to get rid of RM and move to a more robust, reliable “plain” Windows network!

 

If you’ve lost heart with RM, our Windows 2012 solutions might be the answer. Support is easily available from your usual supplier. Don’t feel tied to RM because it’s all the person who sold it to you knew about – Windows networks are used by schools and businesses throughout the world, and without additional layers of software on top slowing things down, your computers will feel like new.

 

We can probably have your network installed, up and running, in less time than it takes our competitors to prepare a quote! Our server solutions are currently powering schools in Hartlepool, Durham and Cleveland. We’ve a wide spread of experience across the education and business sectors throughout the North of England – references are available on request.

 

We’re CRB checked, and have technicians available 24/7 – so if you want your network sorting out of hours to keep disruption to a minimum that’s no problem.

KB: WordPress – “403 Forbidden” Message When Accessing Admin Area

Users may receive the following error message when attempting to access their WordPress Admin Area.

403 Forbidden
Forbidden
You don’t have permission to access /wp-login.php on this server

This occurs in two situations:

1) You’re accessing your admin area from a static IP address, but your static address hasn’t been added to our security system.
2) You’re accessing your admin area from a dynamic IP address, but your account hasn’t been enabled to allow this.

In either case, please contact us to remove this restriction, and quote your IP address which you can find by visiting http://www.pctrends.com/ip

Note in the latter case, this increases the possibility of your admin area being misused by hackers – to reduce the risk of this, ensure you use a strong password!

We’d strongly recommend accessing your admin area from a static IP address. Contact your Internet Service Provider to arrange one of these – note there may be a small charge for this service.

Service Update: FTP Access To Web Hosting Accounts

With immediate effect, FTP connections to web hosting accounts must be made using “passive” FTP. This is to bring these accounts inline with our Remote Backup FTP service. For your reference, the server details to connect to each service are:

Web Hosting: www.example.com – Port 21 (Where example.com is your own domain name)
(Supports both insecure/plain FTP and secure FTP over TLS)

  Usernames are in the format “uxxxxxxxxxxxxxx

Remote Backups: remotebackups.pctrends.com – Port 521

  Usernames are in the format “ftpbackup-xxxxxxx

Service Update: WordPress Login Blocking

With immediate effect, any WordPress sites hosted by us will lock out after 10 incorrect login attempts. This action is to reduce the chances of a successful dictionary attack, where hackers repeatedly try different combinations of username/password to gain access to administration areas. This block takes affect at our firewall and will block access to ports 80 (HTTP) and 443 (HTTPS) from the misbehaving IP address. If you are adversely affected by this change, please contact us to remove the block, or wait 24 hours.
