OPLE IT Blog

A friend of mine runs a well established blogging site at www.d0tk0m.com. He has been experiencing some problems with some of the CSS on his site.

I decided to take a look to see if this could be rectified.  There were two initial complaints;

1. When viewing the site in IE8 there was a huge scrollbar on the horizontal axis.
2. When using IE8 there were problems with the Syntax Highlighter (the view source button and print buttons etc are all over the place)

After downloading the site I took a look at the main background CSS style sheet located here:

/wp-content/themes/pianoblack/style.css

I then started troubleshooting by commenting out various CSS until I found one that did the trick. I also found that it made no noticable style changes to the site:

Hey presto, the issue was fixed.

I have not looked into the issue with the syntax hi-lighter, but may have found the issue.  Will keep updating this post with the findings.  In the CSS for this issue, there are some author comments to show compatibility for IE8 / 7:

If you are unfortunate enough (like me) to live in an area where you get absolutely no phone signal on any network, enter the Vodafone Gateway.  This uses your existing broadband connection as a VOIP gateway.  however this is not without its problems.  Usually if you live in a ‘no signal’ area then you live in an area with low internet bandwidth speeds and no cable (yes I live in the dark ages).  I believe that Vodafone run their own QOS protocol from the box, however internet downloading can reduce the quality of the incoming voice signal.  and if you are uploading, you will be able to hear people fine, but they will complain that your voice is very jerky.

As I am also running a hardware firewall I struggled to see that the device should just ‘plug and work’ as stated in the gateway documentation.  Through research and a lots of calls to the helpdesk I managed to weedle from them a list of ports that the gateway needed DMZ or port forward access to.. After I had added these to my firewall runtime, up it comes all bells and whistles.  HOWEVER they still have not ironed out the HSDPA access over the gateway, as this crashes my gateway every time, requiring a hard reset of the device.

Here is a list of port forwards to IP addresses that you need to allow access to

NTP on UDP-123 to 212.183.133.181

NTP on UDP-123 to 212.183.133.182

Ping on ICMP-8 to 212.183.133.181
