I'm not sure what the issue is, and any help/suggestions are appreciated. I read through the first page of forums here and didn't see anything quite like my problem..

I have the web server installed and listening to port 80 waiting for requests.. I am *not* behind a router -- the ip address reported to me from other computers is *my* ip address -- I have the windows firewall OFF -- I have Norton Firewall and I have attempted it under 3 configurations..

1 - Norton Firewall allows Abyss to access port 80
2 - Norton Firewall allows Abyss to access all ports
3 - Norton Firewall is turned off

In all three conditions, other computers can not access the website hosted on my comp. Abyss doesn't even report an attempt to contact port 80 in the log from the other computer.

Like I said -- any suggestions/comments would help me to figure this problem out.

Have you tried running on a different higher numbered port for testing purposes? Many ISPs block users from running home servers by disallowing remote access to port 80.

I got it working for other computers -- I tried to access it from work and it worked fine... But the computer sitting on the next NEXT to this one still can't see the website.. Do I need to reference it via some other id besides my IP address? I'm not sure why the computer can't see my computer's port 80 simply because we're on the same hub.. Shouldn't the signal go out to the first server it encounters, ask where my IP is, and the server redirect them back to my computer? (This is at home, not at work -- so the two computers are both connected to the same hub, which is then connected to the cable modem of course.)

If I'm still having issues, I'll look you up TRUSTpunk. Thanks. ^_^

Your modem may not be able to support loopback. To overcome the issue open your windows hosts file, and add a line of code, to tell your computer that the domain is on a local IP address.

You don't want to enter your external IP in the hosts file, you want to enter the domain name / dyndns name / whatever you're using to contact your server. The goal of changing the hosts file on the PCs on your LAN is to enable them to connect to your main server PC by name, without the traffic ever going out onto the internet - routers generally cannot handle sending traffic back directly to themselves.

So, for example - your server is at 10.1.1.12

In the hosts file of your main machine (10.1.1.21) you add

10.1.1.12 www.yourdomain.com

Now when you type www.yourdomain.com in IE on your main machine, it goes straight to 10.1.1.12 without resolving the domain name via DNS and trying to send traffic out over the router.

I'm not trying to access any domain name though.. the address I type in on the other comp is not http://www.mydomain.com -- it's http://myipaddress/ .. ? And I don't have any spoofed IP address.. My IP address behind my modem is the same IP address outside my modem.

Here's something different... And I'm boggled by it, not sure why it's happening..

I have this snippet of html code in a page..

<center><img src="./banner.jpg"></center>

It works fine and displays the picture perfectly well... I go to the website, picture is there, I right-click and say "View source" and the <img> tag is present and everything looks normal.

THEN

I create a subdirectory /pictures off the html docs root, move the banner.jpg file there, and change the code to

<center><img src="./pictures/banner.jpg"></center>

NOW it no longer works fine. It does not display the picture -- in fact it doesn't even display a broken-link picture. I right-click and go to "View source" and the <img> tag is nowhere to be seen...

Is the server designed to not let people/pages access subdirectories of the html root unless you specifically tell them to? If it is programmed that way, then which part do I access to add the folder as accessible? If it is not programmed this way, then what might be causing this? And lastly -- why the heck would the <img> tag just simply disappear??

Are you using Windows XP with SP2? If you are, thats your problem, if not, I don't know.

If you do use WinXP and SP2, uninstall SP2 and see if that makes a difference.

I am -- at least if memory serves me. (Not at home again currently) However, before I do that, could I get an explanation as to why SP2 would cause it to do that? ^_^ (I hesitate to do major changes to my comp structure like that unless I really *have* to.. heh)

Its to do with SP2's security features I think. It annoys me too, thats why I don't use service packs on my own PC.

The server does not change your HTML code. It serves it as is.
But your browser can have problems interpreting the HTML code and URLs it references.

For example using ./ in the beginning of a relative URL is not standard and should be avoided.

So instead of ./dir1/dir2/file.ext use dir1/dir2/file.ext .

I have noticed that SP2 with Windows XP changes the code sometimes. A few of my own pages work fine on my laptop but not with this computer I am on now (the family comp). It wont always show the <img tags and it does this on the sponsors page and the sponsor us page.

It only ever does this in IE, not FireFox, Netscape or Opera.

Another reason why Windows sucks.

I urge everyone to disregard any Windows Updates , use special Internet
protection software to keep your Computer protected. Microsoft only gives
you Buggy updates anyway , its best to stay with SP1 like me.

I would just stay with no SP's altogether like I do! I hate Microsoft but as its the most popular OS and things ACTUALLY work on it and you CAN get software for it, I'm staying where I am.

I have found no problems with SP2, if you cannot get it to work it is simply because you have failed to config the new security features to your needs. Most people do not host their own web sites, so by default XP is designed to prevent this, as some virus can exploit this capability.

To allow a web server to work you need to disable or change the built in firewall settings. See http://olly86.co.uk/abyss/xpfirewall.html for more info.

Before you make any further comments I do use security software, firewall (Kerio), antivirus (AVG), and antispyware (Ms AntiSpyware). The best security comes from an uptodate patched system, as well as security software.

I know what you are saying but I agree with what TRUSTpunk said before. Microsoft patches are buggy, thats why I don't use them and I think the SP2 is a bug too. It shouldn't stop an image from showing on a website.

Dunno if it works for you but for me it always did.

KILL all Norton software, especially the firewalls from Norton are a know pain in the ass and always f*ck up the acces to a computer.

I have had so many problems with any of Nortons software ( exept Norton system works, years ago ) that I have decided many years ago never to use any of Nortons products ever again.

Lately I have tested some AV software from them and it f*cked up every test cp I had configured, running W9x to XP.

Do the best thing you can do for yourself, stop using Norton

I agree, I would never use Norton on my own computer. I use ZoneAlarm and no virus protector (I am behind a router firewall with zonealarm and pccillin firewall and virus checker built in) and I have never been hacked or had a virus.

My Dad on the other hand runs Norton and has had 3 or 4 viruses over the last year. Its weird though because my computer is switched on almost 16 hours a day and my dads just 2 or 3 hours a day. Sometimes not even at all.

As we use NTL Broadband it is always connected through the router so its never disconnected.

I just hate the way windows (or it could be norton) changes some of the HTML code it downloads to ommit some images.
