(Update 5/19: I can now reproduce the bug either booted normally or from the live CD)
I've got the strangest bug and no idea what is causing it. While web browsing, sometimes the OS will completely crash. The crash always goes the same way:
First, it shows some text on the screen too fast for me to read, but it looks like red ASCII bullet points followed by white text, both over a black background.
After doing this for about half a second, it enters some kind of loop. The top half of the screen alternates between black/white vertical bars and solid black, while the bottom half of the screen remains solid black.
The only way I've been able to get out of this is by pressing the power button, and doing so shows me the *buntu logo (currently using Xubuntu) and then turns itself off.
Here's why I can't figure out what's wrong:The crash happens in GNOME, KDE, and XFCE. I have since uninstalled KDE because I was just checking to see if it still crashed. Both Firefox and Google Chrome cause the crash. No other programs seem to crash this way; just the web browsers. I've played games and listened to music for hours with no problems. Opening the same pages doesn't reproduce the crash. It happens randomly every hour or so. Even simple pages (like tabs of JPEGs with no HTML) cause the crash. This is a recent install from an Ubuntu 10.04 CD. I was previously using Kubuntu 8.04 and had no issues.
since the launch of Natty I have been having stupid reboots randomly happening, no warning or otherwise occurs just a full reboot. This only seems to happen when browsing (FF or Chrome) and I have disabled every one of my addons and done the usual checks - baffled I am...So I had this with the upgrade I did on launch day, so naturally I did a full wipe and fresh install. Same situation - personally I cannot deal with this happening all the time so I went back with another full wipe to Maverick and all has been well.
Anyway I thought leaving this a few weeks would mean the community would have seen and squashed dealbreaker bugs so I re-installed yesterday, today the crashes came back again so I throw myself to your wisdom - anyone else seen this, know where I should be looking for ideas? My logfiles don't show anything prior to the reboot as an error.In all honesty I do not want to go back to maverick and cannot believe that Ubuntu have released such a bug riddled distro.
This happens at random and the problem persists even when using an alternative browser (Firefox & Chrome), being redirected to the same website. Sometimes it's [URL] going to [URL] going to AOL Lifestream.
I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:
I have looked at other threads on this subject and am still confused. Several weeks ago I had issues with browsing taking forever to resolve a page. When I changed my router to Open DNS settings that seemed to fix the slows and when I replaced the Open DNS IP's with the Google IP's, things were even quicker. Now I am back to the slows but there is no resolution latency it's just a delay when clicking a link, nothing happens and then the page eventually loads but you see the ads write on the page after the text loads. It's just not snappy. My nsswitch.config looks like this:
# /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality.
Certain websites do not open on any browser on my 10.04. I tried [URL]... and those sites were up. I rebooted into windows and it opens. I changed my dns server to open dns then google dns but did not solve the problem.I have a dsl connection with automatic dhcp. While googling i read about nsswitch.conf and this is what is presently looks like
Code: # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file.
I have a weird problem with opening certain websites under ubuntu. I tried at windows and i have no problem. The DNS in windows is my modem 192.168.1.1 but under linux for some strange reason this won't fly.For example ......com won't open on firefox, but ping and traceroute works just fine.
UPDATE: ping and traceroute doesnt work for www.......com but only for [URL]After using lynx this is what i got back
Quote:
micdhack@micdhack-laptop:~$ lynx ......com Looking up '......com' first Looking up ......com first Looking up ......com
[code]....
Is there a way to use another dns than the one that i get from my internet provider?
I have installed Fedora 10 and centos 5.3 on 30 system in my home office. everything works fine except accessing https websites. the problem persists in both centos and fedora even after changing firefox versions. what's worse is the problem is not resolved after changing other browsers. so the problem is not browser-centric. i think it has something to do deeper in fedora and centos. also note that i have disabled firewall and selinux but in vain. the problem is still there across all the systems. it's really a show-stopper for me.
I have seen some similar issues here in the forum but I am not sure if they are related.I post seperately to avoid confusion there. However, I have installed Suse 11.2 on my Asus netbook. Network with cabel is ok, but as soon as I unplug, internet does not work.I have a fritz box. ping fritz.box does NOT work ping 192.168.178.1 does work. internet does not work.
ok, next the info in the system tray: everything looks fine. Status: connected Nameserver is 192.168.178.1. Seems about right. Domain: fritz.box
I've been an Ubuntu user since Jaunty, and i gotta say, i'm really impressed, especially with the great Karmic! However, ever since my first ubuntu installation, i've had a very awkward problem: My internet does not open any of the following websites: Rapidshare Megaupload Urbandictionary
I don't know if there are other websites I wouldn't be able to access, but those are the main ones i use frequently, now here's what I tried so far (nothing worked): 1- Use a different browser (none of firefox, opera or konqueror worked) 2- Edit the etc/hosts file 3- add a line in the etc/hosts.allow file It seems so stupid to have to power on a virtual machine to download a rapidshare file!
here i would like to inform you that my company ask me to block facebook site at the work time it is: 08:00-12:30 and 14:00-17:30 in proxy server.i'm still confuse how to do!i need the details configuration in squid regarding how to block the sites
I have installed windows server 2003 on my computer, and i can surf the internet with my gui-based web browsers.
I have also installed vmware workstation 6.5 on the same computer, and successfully installed fedora 12 in vmware, with network is bridged.
I can successfully ping websites at the command line, e.g., ping [url], it did get replies with time and ttl, but i can't open the websites with firefox or conquerer browsers.
I have recently installed Ubuntu 10.04 LTS. It got installed and is working o.k. However I am facing one typical issue: When ever I try to open any secured site ( like bill payment sites etc. ) , firefox simply does not open these pages. However at the bottom left it displays -Done.
What are all the ways you could think of that someone could view your browsing history, upstream from your machine? They don't have physical access, there's nothing on the computer itself and the person trying to hack has skill so I'm thinking like monitoring a proxy somehow, using the ip address somehow, compromising the modem in some way, possibly having access to google account etc. I am new to ubuntu and have really dug it so far but I want to figure how this is/was being done
I have installed MoBlock as instructed here: [URL]
After installation I created my own list file in /etc/blockcontrol/custom-blocklist.p2p and have the following uncommented at the bottom of /etc/blockcontrol/blocklists.list:
Code: Yahoo:98.137.149.56 Google:74.125.47.147 When I do:
[Code].....
Recently I just noticed that the locallist rules seem to have no effect. I will always get "destination port unreachable" even if the locallist entry in blocklists.list is commented out.
However, whenever I try to browse to that IP, even when blockcontrol is on, even by typing the IP into Konqueror (not the domain name), it lets me go there every time. How can I know that my other applications will not to do the same thing? How can I lock this down and test it empirically to be sure?
What methods exits to restrict which directories a user may browse on the filesystem. I want to prevent php scripts from being able to view system files. I've seen two solutions, but neither are satisfactory:Chrooting a directory that the script is in, but this requires that all the necessary php libraries/files are moved/copied into the right place relative to the chroot directory. I don't feel that I have the technical ability to achieve this.Putting php into safe mode and disabling *nasty* php functions. But this is ineffective if just one obscure *bad* php function is missed.
I'm using Ubuntu x64 (dunno which version, but I don't think it matters) and I'm concerned about security with PHP.I remember using lighttpd and I had some mystic configuration and the secuirty was perfect for me - if one website gets hacked then the others are still safe (kinda).Now with apache2 if I enable safemode I'm still able to go outside web directory and actually I can go really far untill user/group matches.I tested the system with r57shell and I was able to mess up other websites.Is there a way to disallow access to other websites?
I have freshed installed lucid.Linux ubuntu 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/LinuxThe problem is firefox is very very slow to open web sites.
I come to Ubuntu with the notion that it is much more secure than Windows. In XP I had an anti-virus, third-party firewall and sundry softwares against spybots, rootkits etc. The anitivirus blocked the suspicious web pages while browsing. I generally avoided public networks, carrying a portable internet device Do I need similar stuff with Ubuntu.
I'd like to be able to limit access to a particular website, based on the time of day. I would also like to be able to password protect this if possible.So for instance, from 7am until 10pm daily, I can access URL... but after 10pm it redirects to 127.0.0.1 or something. And this configuration be protected by only allowing a certain user (other than root) to change the config?
I want to block a list websites from myself using a password that I don't know.I would randomly generate it or something.Everything revolves around sudo, though, so I don't know how.Long to short: how do I blacklist websites using a password other than my sudo password.
A computer security researcher has released a plugin for Firefox that provides a wealth of data on Web sites that may have been compromised with malicious code.
The plugin, called Fireshark, was released on Wednesday at the Black Hat conference. The open-source free tool is designed to address the shortcomings in other programs used to analyze malicious Web sites, said Stephan Chenette, a principal security researcher at Websense, which lets Chenette develop Fireshark in the course of his job.
I don't know is this the right place to ask, but i must ask some questions Here's my problem.I'm a student in highscool,and here we use Linux(ubuntu) OS .Every classroom has like 30 PC's connected with the main computer(the teacher's one) so....3 days ago we were forbidden access to some websites it says This domain is Blocked.By the way the Linux version installed is 7.04(feisty Fawn) i tried disable cookies that did not worked,also tried to whitelist some website,that also didn't worked out
I have been trying to get Squid to work so that I can restrict access to a particular web site during certain hours every night. I can't seem to get it working, however. I am still able to access the site. The following are the relevant lines from my squid.conf file:
acl restricted-domain dstdomain "/etc/squid/denied_domains.acl" acl test time 19:00-20:00 acl bedtime time 22:00-23:59
Since Ubuntu and other Linux Distros are free to download and distribute. Would it be illegal for me to have a Small Business of my own that would charge individuals/small-businesses to Install and Setup Linux desktops. I wasn't sure how that GPL license worked. I figured I would be charging individuals for setting up Linux Desktops on their machines or small business/offices and training/teaching them on the various applications they could install on their own.
Also, would it be illegal to create websites using Apache, Tomcat and other Open Source tools and then sell those sites. I figured many people are turned off by learning or installing something other than Windows desktops on their pcs, just because it is different. If this cannot be done under the GPL license, then could someone tell me how I could go about starting my own small business to legally Setup/Install Linux distributions.
When I have taken pictures, I usually like to open them in a Firefox tab, especially if I already have Firefox open. I was wondering if there is any particular reason Firefox opens the pictures in random order. It would make more sense for it to open them according to their order (by date) in the Konqueror window I had the folder open in.
