You have DNS issues.

From the ping command, I see that your system resolves youtube.com to 120.28.26.50. Well, that is not Youtube or Google. No, that's an internet sevice provider in the Philippines. That's scary. Somebody is trying to be the "man in the middle" here! Be aware.

Try using Google Public DNS on your system instead. Follow the instructions in this answer on how to do that: https://askubuntu.com/a/310752/88802

$ whois 120.28.26.50
% [whois.apnic.net node-7]
% Whois data copyright terms    http://www.apnic.net/db/dbcopyright.html

inetnum:        120.28.0.0 - 120.28.255.255
netname:        GLOBET-PH
descr:          Globe Telecom/Innove Communication
descr:          Internet Service Provider, Makati City
country:        PH
[...]

And it has no reverse DNS (all Google servers have that!):

$ host 120.28.26.50
Host 50.26.28.120.in-addr.arpa not found: 2(SERVFAIL)

In the Netherlands, it looks like this (and you should have similar results - though the IP address will be different of course):

$ whois 173.194.65.93 # result of ping youtube.com
[...]
NetRange:       173.194.0.0 - 173.194.255.255

Can somebody explain why in my Ubuntu 13.04 the facebook site and youtube site can't be opened by Chrome or Firefox. Other sites can be opened except for this two site. I really need a hand here.

result from ip addr:
```
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

  What do you mean "it cannot be opened"? Please be more specific. What is the error you get? "Connection refused", "Could not resolve hostname...", "Connection timed out", "SSL error" etc. If websites aren't reachable from any browser, this is more likely to be a networking issue than an issue with Ubuntu.

  sorry to bother you @gertvdijk i'm just a newbie to ubuntu.

  I also see mtu 1402. Did you configure that yourself? An ethernet connection is usually configured for an MTU of 1500.

  Here's a long shot - what does you /etc/hosts file look like?
- victornolii almost 11 years
  
  @gertvdijk i configure that myself since i tried to see the internet and read someone post about changing it to 1402. should i change it back to 1500?

  /etc/hosts is not your problem. (Great practical jokes there if you have access to a friend's system!)

  @Marc it looks just like the other files. (can't really comprehend, i'm really new about all this)

  @victornolii Read my answer: "Try using Google Public DNS on your system instead. Follow the instructions in this answer on how to do that: askubuntu.com/a/310752/88802 "

This has nothing to do with a page not being able to load in a browser - this is only for addons like Adobe Flash and fonts.

i live here in the philippines. so it is the internet service provider that makes this? youtube channels can be opened until the video, but it won't play facebook is worse. it just open a empty page.
gertvdijk almost 11 years

@victornolii If this in the whois info I added is really your internet service provider, then they are pretending to be Youtube! I would not trust this connection anymore.
victornolii almost 11 years

so there is no solution then to change the internet service provider?
gertvdijk almost 11 years

@victornolii I've given some things to try. I can't tell from here what would be the solution - I cannot see your screen and I don't have access to your internet connection. :) Have you tried the suggested change of DNS servers? That could be your solution here. And also please include all the things you've changed on your system in your question. As you've mentioned changing MTU - what more is there you haven't told us yet?
victornolii almost 11 years

i only changed my MTU. you tried to hack me? LOL
