Firefox became very slow and strangely waits for 192.168.101.1:8888

  • 772

Firefox started loading urls with a huge delay despite having a fast plan (70 MBit download)

Also in status line at the window bottom it sometimes prints waiting for 192.168.101.1:8888

My laptop is connected via WiFi with no dns-nameservers configured in /etc/network/interfaces and my router has wired connection to the ISP.

Who does that IP address belong to? Why does my browser wait for that strange address?

UPDATE:

I've conclude that my laptop was hacked.

Here what shows in the conection telnet 192.168.101.1 8888 the command GET / HTTP1.1

Look at <LI><A HREF="data_durablis/">data_durablis/</A>. I created that folder by myself, thus these links to my root dir folders, not typical linux install folders.

  1. 192.168.101.1 is a private IP from RFC1918. Meaning it's not routable through the internet. No hacker (on the internet) can use it. With that said your ISP is using 10.134.0.1 & 10.254.246.49 inside their network which is also a private IP RFC1918. So your ISP is using a private IPs inside their network, thus they're the only ones that could route to 192.168.101.1

    The http site that's hosted on 192.168.101.1 8888 is odd but are just a bunch of links to a typical linux install.

    clamscan output just shows a bunch of windows viruses (from what i can tell)

    So from what i can see, the most logical answer is your ISP has a fast (70 GBit???) connection to their LAN, but a slow pipe to outside Internet. To speed things up your ISP is running a proxy server and tunneling all http requests through 192.168.101.1:8888

  2. the clamav antivirus hits are all for windows viruses that won't effect windows. I am unaware of any viruses working in wine but i guess its possible, i am unaware of any viruses being able to jump from wine to linux but i guess it is possible even if its very very very hard indeed.

    This looks to me like your service provider doesn't know what they are doing and have broken their proxy server or you have not configured your router to provide NAT properly.

    The best advice at this stage would be to phone them and ask them to check your router settings and check their proxy server, sometimes its easier to just say you need to connect your mobile via wifi not a linux computer, some ISP's get scared of linux.

  3. Ever heard of Nginx? That's a GPSV [General Purpose Security Vulnerability] in the form of an on-line http server that anybody can connect to, brought to you by the makers of your favorite browser but also thoughtfully included (without your permission, naturally,)in the CUPS distribution [Common Unix Print Spooler] that runs dutifully and apparently cannot be disabled even when running on laptops that never had and never will have a printer.

    My suggestion is to run FreeBSD in a gateway machine with dual NICs, one connected to the Internet and the other connected to your internal ethernet using the Berkeley Packet Filter [ ipfw ] application to stop the intruders. Be aware that most Mozilla browsers will choke because they will not stop waiting for replies that never come. While everyone was sleeping, advertisers stole the Internet. It will take a bit of wrestling and inconvenience to take it back from them.

    Uninstall the Nginx package and make certain it remains uninstalled and that should solve your problem.
