General Questions about Web Pages

Why isn't my site loading?

Take note of the error code. If it's "403" or some variation on "permission denied", you'll need to adjust permissions on the file such that it is world readable. Use the following command:
chmod o+r [filename]

Directories need to executable as well. Use the following command:
chmod o+rx [directoryname]

If the error code is "404" or some variation on "Not Found", make sure the file in question has, in fact, been uploaded, and that you've linked to it with the correct filename. Remember that filenames are case sensitive.

If your graphics are not appearing, make sure that they are world readable and correctly linked.

What image formats can I use?

Acceptable web image formats include

JPEG images allow a wide range of color depth and allow you to compress the file. Higher compression will result in faster load times, at the expense of image quality.
PNG (Portable Network Graphics) files are a lossless image format originally designed to improve upon and replace the gif format. PNG files are able to handle up to 16 million colors, unlike the 256 colors supported by GIF.
GIF images exist in 87a and 89a formats. gif89a allows transparent backgrounds (important if your page has a colored or textured background). It is also possible, using programs designed to do so, to string .gif files into an animated loop.
TIFF (Tagged Image File Format) files are lossless images files, allowing for very high-quality images but also larger file sizes.

How do I create or modify subdomains and MX records?

You may use the DNS Management console at Note that you will still need to sign up for web service if you want Panix to host a website at such a subdomain.
