[SOLVED] https works....http doesn't

[photoman]

Hi all,

I have my Linux laptop running Katatonic Koala at the moment. It is connected via CAT5 to a switch. The switch then connects to my router. All five of my computers are connected to the switch, actually. The only one that won't talk to any sites other than https secure sites is the Linux box. I am not well-versed in the inner workings of Linux and need some help in what I need to do so that regular http sites work. You guys always have the right anwers so I will wait humbly for your replies.

Have an awesome week!!

HTTP vs. HTTPS should not matter to the switch nor to the router. BTW, what IS Katatonic Koala? I know about Karmic Koala, Lucid Lynx, Jaunty Jackalope, but I've never heard of Katatonic Koala... ??

I think the first thing to do is determine if it is a browser issue or something more general.

Open a terminal and type

telnet www.google.com 80

If you get connected to google, type helo and press enter. That's one lower case ell. You should get a load of html back. If you do the problem most likely lies with the browser, if not I would suspect a firewall.

LOL...I just called it Katatonic (as in a catatonic state) because it's giving me fits trying to connect to the Internet. It's not really a real version.

Anyway, for whatever reason, it will not connect to ANYTHING that is HTTP. It only connects to HTTPS secure sites. I even downloaded a different browser (Konqueror) and it won't connect to HTTP either. All other computers on my network are fine. I think I may have to just try to manually set up a static IP and set up the parameters that way. What a PITA.

Thanks.

It says that I connected to Google and then I typed helo. It says HTTP/1.0 400 Bad Request. After that, it's a bunch of html that ends with "Your client has issued a malformed or illegal request" and then it closes the connection.

I didn't install a firewall that I know of on my Linux computer (does it do this by default?) and my other computers are not blocked so I am not leaning toward the router being the problem. Thoughts?

Thanks.

You can interpret that as a successful connection, so I doubt that
anything external is causing it. Your browser may be misconfigured
to use a proxy or something. What browsers have you tried?

Well, this is a new wrinkle for me. I have 2 9.04 and 1 10.04 ubuntu laptops in my house and non of them have this problem with our Linksys and Netopia routers and switches (including a linksys/cisco 1GB switch and power-line bridge). So, I am scratching my head. Since https works (encrypted payload other than TCP/IP headers), but http doesn't, I am sitting here scratching my head... huh? Something is interfering with the payload, and if it does it with http, it should (logically) also interfer with https packets. I'd double check the router/switch security settings to see if it may be doing something like enforcing encrypted tunneling (swag).

So, what make/model of router/switch are you running?

Ok, so I'm also left scratching my head. I figured I'd try to manually configure the laptop with a static IP. So, I tried to log in to my router. It wouldn't have any of it. I couldn't get in to save my life. I just did a reset on the router to reset the password and was able to log in to it. I checked all of the settings and specifically the firewall and any blocking of the "unknown" Linux laptop. Everything was identical across the board between my Windoze computers and the Linux laptop.

Meanwhile, back at the ranch, I then checked the ifconfig on the laptop. All appeared normal and it was showing as "connected." I then opened Firefox and, lo and behold, the fool thing connected right up with the Internet. I have NO CLUE what happened to block it but apparently resetting the router fixed the whole mess. Now I'm back in business. Time for some updates!!!

Thanks to all!!

The solution, oddly enough, was just to reset my router. I don't have any idea why it didn't affect any one of my other four computers because I did absolutely nothing to the Linux laptop but it works and I'm happy!!

Thanks for all of the suggestions!!
