Can't get onto ONE website!

[StackAttackB]

Hi everyone,
I need some help. I am trying to access the website www.mycampus.phoenix.edu (online school website) on my laptop. I have been able to access it before and then one day it just would not pull up on my laptop. I have a wireless connection. The website comes up fine on my desktop. One day I even brought the laptop into my work, where we have a wireless network, and I was able to access the website fine in there, I just can't do it at home. I have tried everything I can think of, plus I've called my school tech support for online classes and they walked me through many different things. I've run scans for spyware, disabled the firewall, flushed dns, disabled my antivirus, reset my router, and even reloaded the whole operating system last night. I've done other things, too but just can't remember them right now. Still nothing. Any ideas???

Hi StackattackB and welcome to the TS Forum :wave:

Sorry to say but I cant access that website either, it may be that the campus has disabled access except from certified ISP's, some do this as a security measure.

I tried a Ping and a tracert and both come back as an unable to resolve, this usually means that the DNS (Domain Name Servers) dont have an IP listing for the website.

Regards

Thanks for trying. I am able to access it from other networks, though. Even on my desktop I can access it. I tried to ping it on my desktop and it said it couldn't be found, but yet I was still able to access the website on that computer.

Yeah some sites are like that, our kids school cant be pinged but can be reached, i just remembered that useless bit of info.

Cant think why you can access it on one but not the other, like i said I cant on my laptop unless I add .com on the end.

Regards

Hi,

Maybe (just maybe) there were restrictions set on your system which prevents that access. If you'd like a quick check for such restrictions, post a HijackThis log as an attachment.

PS. Usually after the .edu in the link theres something else at the back? My school's site goes .edu.sg, sg stands for Singapore, where I stay. Perhaps you need to add .something. Hope this helps.


Regards,
Your friendly momok =)

testing browser vs. website-browser problem

issues with PING vs. browsing;

ping is a special protocol and http: (ie: url access) is another.
both forms translate a name into an ip address by accessing a DNS.

Step 1)
use run->cmd /k nslookup domainName.com
where domainName.com removes the http:// and
only contains the www.google.com, for example.
you must get back an ip-address or the site can not be accessed from the general Internet.

Step 2)
use run->cmd /k ping an ip-address to test
the routing to the site.
*THIS IS PROBLEMATIC* in that, an admin can choose to block ping replies while still allowing HTTP:// access.
this is done in an effort to reduce hacking attacks on the site.

Step 3)
use your browser to access http://an ip-address/
this is likely to repeat your original symptom; no reply

Step 4) is it the browser or the site?
test the site for access and blame the browser if this works;

1. get a command prompt (run->cmd /k)
2. enter TELNET ip-address 80 (hit enter)
3. type GET / HTTP/1.0 (enter)
4. type (enter again)

if the site is running an you have a connection to it via telnet, then the reply looks like

HTTP/1.0 200 OK
Cache-Control: private
Content-Type: text/html; charset=ISO-8859-1
Set-Cookie: PREF=ID=11671d5c1d20013f:TM=1180

you have a browser hijacking problem if Step4 worked!

I can't access http://www.mycampus.phoenix.edu/ either. However, just remove the www from the front of it and access it as http://mycampus.phoenix.edu/. Then it works.

Now thats freaky, I did try using HTTP:// then the mycampus bit and it didnt work, now it does, i even tried using HTTPS:// which is what shows for my kids school and it didnt work, but now if you click the link Kitty posted first, then check the address in your browser it shows as

https://mycampus.phoenix.edu/

This didnt work the other day.

Jobeard, its gotta be said man but talk about overcomplicating an answer.

Momok it cant be spyware if 2 diff people cant access the site, I know my Laptop is clean, ( i dusted it last week with pledge).

Regards

 

[momok]

Ah yes. I realised too.
And thats an amazingly simple solution too lol.

Jobeard, its gotta be said man but talk about overcomplicating an answer.

it's not an answer, but a diagnostic technique to distinguish between
a browser problem vs a network access problem. FEW understand the
inards of HTTP access as shown in step4 (which is exactly what all browsers
perform). A difference would occur ONLY when the browser has been hijacked

 

[StackAttackB]

I've tried all forms of the website. Leaving the https, http, www. out, etc. Nothing seems to work. But then as soon as I get onto another network (any network besides mine) I can access it.

using nslookup validates this statement!

$ nslookup www.mycampus.phoenix.edu
Server: dns-cac-lb-01.orange.rr.com
Address: 66.75.164.90

*** dns-cac-lb-01.orange.rr.com can't find www.mycampus.phoenix.edu: Non-existent domain

Jeff@ltbeard ~
$ nslookup mycampus.phoenix.edu
Server: dns-cac-lb-01.orange.rr.com
Address: 66.75.164.90

Non-authoritative answer:
Name: mycampus.phoenix.edu
Address: 204.17.25.80

there's only a few choices which lead to your symptom

1. firewall is blocking it
2. router is blocking it
3. hostfile contains that domain -> 127.0.0.1
4. your browser is hijacked
5. your ISP/DNS can not map the url into an ip address

if you can ping 204.17.25.80, then item(5) is false.
even this timeout STILL shows the DNS can resolve the IP; phoenix.edu is just
blocking ping replies

ping mycampus.phoenix.edu
