Ubuntu :: Using Wget To Save A Frequently Updated Webpage?

Mar 3, 2010

I'm trying to figure out how to use wget to save a copy of a page that is frequently updated. Ideally, what I'd like it to do is save a copy of the page every minute or so. I don't need multiple copies; I just need to know what the most recent version was. Also, if the page disappears for whatever reason, I don't want it to save the error page, just wait until the page is up again.

Ubuntu :: Wget Webpage And Some Links For Offline View

Apr 25, 2010

I've looked around the other threads as well as the wget man page. I also Googled for some examples. I still cannot work it out. From the page [URL] I want to download the 48 linked files and their corresponding information page.To do this (the first file) by hand I click on the line that saysApplications (5) Go to the first optionDell - Application Open and copy the linked pageApplies to: Driver Reset Tool Then back on the first page click on the Download button. On the window that opens up I choose to save the file.

Then I move on to the next option (which is Sonic Solutions - Applications) and repeat this until I would have all my files. I do not want to download the many other links on this page. Just the above mentioned, so I can take it back to my internet-less place and refer to it as if I was on the net. I am using the 9.10 LiveCD at my friends place.

Networking :: See Whether Wget Can Be Used To Generate Actual Url Hits On A Webpage?

Jan 16, 2011

I am trying to see whether wget can be used to generate actual url hits on a webpage. This does not look good so far�. I changed the following lines in /etc/wgetrc to:

Code: http_proxy=http : / /<proxy_ip>:<port>/ use_proxy on Output :

Code: root# wget -c <url>/ > /dev/null
--2011-01-16 12:26:38-- <url>
Connecting to <proxy_ip>:<port>... connected.

[code]....

2011-01-16 12:26:39 (88,9 KB/s) - `index.html.3' saved [50548] This does NOT generate a hit on the actual web page! It does not seem like the, > /dev/null part is working either... How can I get this to work?

Software :: Resume An Interrupted Wget Using Wget.log?

Jun 19, 2011

If a wget download is interrupted (like if I have to shutdown prematurely), I get a wget.log with the partial download. How can I later resume the download using the data in wget.log? I have searched high and low (including wget manual) and cannot find how to do this. Is it so obvious that I did not see it? The wget -c option with the wget.log as the argument to the -c option does not work. What I do do is open the wget.log and copy the URL and then paste it into the command line and do another wget. This works but the download is started from the beginning, which means nothing in the wget.log is used.

Ubuntu :: Xrandr Doesn't Save Changes - How To Make It To Save Changes

Jun 16, 2010

my mediacenter is attached to an beamer with the optimal resolution of 1280*720 ubuntu 10.04 doesnt offer me this revolution (on my intel 915 graphis controller). this means i have to add this resolution to the possible resolutions. first i used cvt

Code:

cvt 1280 720 60

and got this result:

Quote:

# 1280x720 59.86 Hz (CVT 0.92M9) hsync: 44.77 kHz; pclk: 74.50 MHz
Modeline "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync

then i added this to xrandr

Code:

xrandr --verbose --newmode "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync

and

Code:

xrandr --verbose --addmode VGA1 1280x720

now i can select and use the new resolution - until next reboot. after an reboot 1280x720 is again not available. even if i work with sudo - the resolution isnt there....

Ubuntu :: 11.04 Frequently Crashes / Why Is So - Fix It?

Sep 1, 2011

Anywhere from 2 -> 6 times a day, my computer will freeze up. If any audio was playing, it will repeat the last few seconds over and over again.
I've been dealing with the problem for a couple of months now, with no solutions.

It can happen anytime, but it tends to happen on my screensaver about 50% of the time after I've locked my computer and during the early morning (12am onwards) when I have a full-screen video playing, but it's never done it at night in the same circumstances.

I am confused and just can't figure out the problem.

Computer info:
Mac Mini (2010) 2.4GHz
8GB RAM
Dual 24" Monitors @ 1920x1080.
Ubuntu 11.04 64-bit.

Ubuntu :: Natty Crashes Frequently / What To Do?

May 9, 2011

I just upgraded to Natty on a (almost brand new) HP pavilion dm4t. I'm finding that it crashes pretty frequently, in a variety of ways that might or might not be related.

1) Sometimes (every 2-3 days) it will just blink out and go back to the login screen. This usually happens within a minute or so of logging in. If I log in again after this, it will usually crash again. A restart of the system typically will make the problem go away for at least a few sessions.

2) If I leave the computer on for a while, the screensaver will freeze and nothing can get me back to the desktop. Processes seem to still be running behind it (I left some music playing once and the music continued to play, but the screen was black and I couldn't get back to my desktop - I had to do a hard shutdown)

3) A perhaps unrelated problem, every ten sessions or so when I log in the indicator applet will be gone and an error telling me that indicator applet failed to load (or something to this effect)

Btw I'm using ubuntu classic rather than unity (just because I like it better). I haven't used Unity enough to know whether these problems also occur with it.

Ubuntu :: Skype Frequently Breaking Under 11.04

May 10, 2011

I started using 10.10 a few months ago and had very few problems aside from a few minor issues with Wine. I frequently used Skype under 10.10 and it ran perfectly with no issues whatsoever.

Recently I upgraded to Ubuntu 11.04 and well... basically things have just gone downhill from there.

Over the past few days Skype has been ridiculously unstable, I'll be talking to somebody using text chat and it will essentially freeze up. These freezes can occur within minutes of starting Skype and are very infuriating. I am still able to type and send messages but the "message not sent" icon will appear next to each of them and the timestamp on each message will be identical (the messages in question will not send even after a restart of Skype). This problem will persist until I force-quit the application, closing it normally will not work and often I have to restart my computer entirely before it will work again.

I have tried updating to the latest version of Skype to no avail (if anything I think it has made matters worse, but that may just be my imagination.)

I'm not particularly command savvy, just posting on the off chance that anybody has encountered the same problem or has found a relatively simple fix. I don't really want to have to re-install the entire OS just to roll back to 10.10.

Ubuntu :: While Using FTP, Connection Closes Frequently?

Mar 11, 2010

I'm using Ubuntu 6.06 and Apache.I connect to the machine via FTP. It seems as if the connection times out every few seconds. If I u/l a file it will take 15 seconds to connect. Once that connection is open I can u/l more files instantly. If I wait a few seconds it closes, then I have to wait another 15 seconds for it to reopen. Any ideas how to make it not time out so frequently?

Ubuntu :: Frequently Getting Grub Rescue Prompt

Mar 12, 2011

I'm having a issue. It first started a few nights ago, and after booting from the live cd and reading around, I saw it mentioned somewhere that it might help to update GRUB. I did this using sudo update-grub. This took care of the issue, with an unexpected, but not altogether unwanted result: instead of having to choose a temporary boot device to boot on to the external drive Ubuntu is on, I got a grub menu which showed the the OSs for both HDDS. I thought all was fine, but a few days later, same thing. Updated grub again, and all was okay. Tonight, it happened again.

When I try to update grub now it says:
Code:
ubuntu@ubuntu:~$ sudo update-grub
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).

Here's the result of the boot info script.
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for (,msdos1)/boot/grub.
=> No boot loader is installed in the MBR of /dev/sdb .....

Ubuntu :: Monitor Screen On 10.04 Goes Blank Frequently

Jun 21, 2010

I have a new ubuntu 10.04 install, it is the third that I have done recently. On this particular install (unlike the others) the screen goes unexpectedly blank at seeming random intervals and any motion restores the screen. It is acting like a screen saver with the blank screen option set. My screensaver preferences are set to use a screen saver 'for a 7-minute idle period. The lock screen option is off. For AC power management never is chosen for "put computer to sleep" and 30 minutes is chosen for the "put display to sleep" option.

This is a compaq presario desktop.

Ubuntu :: Laptop Frequently Freezes Up And Has To Be Hard-reset

Jan 20, 2010

Under 9.10, my laptop frequently freezes up and has to be hard-reset. At first I thought it was a Firefox issue because it happens most often when I'm on the web, but the computer also crashed on me while doing things in Synaptic, so it must be something else. I have an HP Pavilion z5000 with an Ati Radeon 9600 Mobility, 1.25 GB of RAM and 120 GB hard drive.

Ubuntu :: Put Frequently Used Programs In Ram For Faster Startup Time?

Jun 12, 2010

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.

Ubuntu :: Programs Randomly And Frequently Stop Responding?

Mar 19, 2011

programs (especially Firefox, though I haven't used other programs much) stop responding rather frequently without warning and after some time they just start responding again. Apt-get also takes ages to unpack stuff when I'm upgrading/installing something, that might be related. According to top there is barely any cpu usage at all during these freezes. I had this issue on a stock Lucid install. When Maverick came out, I tried that one, and the issue still existed. On a fully upgraded Maverick system, it's still there as well. Windows works without a hitch, as does Ubuntu running under a VM on windows.

System specs:

CPU: Phenom 2 x4 945 @ 3 GHz
GPU: Radeon HD 5770 with fglrx
4 GB of ddr3 ram
Motherboard: Asus M4A89GTD PRO
Hard drives: 2 WD 1.5 TB drives running on a fakeraid 1 array
