  • 13.10 upgrade dropping wifi [on hold]

    - by Daryl
    Almost a complete newb here. After my last upgrade from 12.04 to 13.10 my wifi now randomly drops. The only way I can get a signal back is a shutdown and restart otherwise it shows no network is even available to connect to. Had no problems until the upgrade. Any help would be appreciated.

  • Help with DB Structure, vOD site

    - by Chud37
    I have a video on demand style site that hosts series of videos under different modules. However with the way I have designed the database it is proving to be very slow. I have asked this question before and someone suggested indexing, but i cannot seem to get my head around it. But I would like someone to help with the structure of the database here to see if it can be improved. The core table is Videos: ID bigint(20) (primary key, auto-increment) pID text airdate text title text subject mediumtext url mediumtext mID int(11) vID int(11) sID int(11) pID is a unique 5 digit string to each video that is a shorthand identifier. Airdate is the TS, (stored in text format, right there maybe I should change that to TIMESTAMP AUTO UPDATE), title is self explanatory, subject is self explanatory, url is the hard link on the site to the video, mID is joined to another table for the module title, vID is joined to another table for the language of the video, (english, russian, etc) and sID is the summary for the module, a paragraph stored in an external database. The slowest part of the website is the logging part of it. I store the data in another table called 'Hits': id mediumint(10) (primary key, auto-increment) progID text ts int(10) Again, here (this was all made a while ago) but my Timestamp (ts) is an INT instead of ON UPDATE CURRENT TIMESTAMP, which I guess it should be. However This table is now 47,492 rows long and the script that I wrote to process it is very very slow, so slow in fact that it times out. A row is added to this table each time a user clicks 'Play' on the website and then so the progID is the same as the pID, and it logs the php time() timestamp in ts. Basically I load the entire database of 'Hits' into an array and count the hits in each day using the TS column. I am guessing (i'm quite slow at all this, but I had no idea this would happen when I built the thing) that this is possibly the worst way to go about this. So my questions are as follows: Is there a better way of structuring the 'Videos' table, is so, what do you suggest? Is there a better way of structuring 'hits', if so, please help/tell me! Or is it the fact that my tables are fine and the PHP coding is crappy?

  • 1 click backup for my websites

    - by Si Philp
    I have a windows reseller account that I only really use for personal use. The host company doesn't currently offer a 1 click backup. I am looking for something to automate some kind of backup that does the following: Backups all files Backups all databases I know other companies offering such a tool but I am not looking. I have thought about writing a tool that does this but thought there might be something out there that does this already?

  • Best language on Linux to replace manual tasks that use SSH/Telnet? [on hold]

    - by Calab
    I've been tasked to create and maintain a web browser based interface to replace several of the manual tasks that we perform now. I currently have a "shakey" but working program written in Perl (2779 lines) that uses basic Expect coding, but it has some limitations that require a great deal of coding to get around. Because of this I am going to do a complete rewrite and want to do it "right" this time. My question is this... What would be the best language to use to create a web based interface to perform SSH/Telnet tasks that we would normally do manually? Keep in mind the following requirements: Runs on a CentOS Linux system v5.10 Http will be served by Apache2 This is an INTRANET site and only accessible within our organization. User load will be light. No more that 5 users accessing it at one time. perl 5.8.8, php 5.3.3, python 2.7.2 are available... Not sure what other languages to check for, or what modules might be installed in each language. The web interface will need to provide progress indicators and text output produced by the remote connection, in real time as it is generated. If we are running our process on multiple hosts, they should be in individual threads so that they can run side by side, not sequentially. I want the ability to "trap" on specific text generated by the remote host and display an alert to the user - such as when the remote host generates an error message. I would like to avoid as much client side scripting (javascript/vbscript) as I can. Most users will be on Windows PC's using Chrome or IE as a browser. Users will be downloading the resulting output so they can process it as they see fit. I currently have no experience with "Ajax" or the like. Most of my coding experience is old 6809 assembly, Visual Basic 6, and whatever I can cut/paste from online examples in various languages (hence my "shaky" Perl program) My coding environment is Eclipse for remote code editing, but I prefer stuff like UltraEdit if I can get a decent syntax file for the language I'm using. I do have su access on the server, but I'm not the only one using this server so I can't just upgrade/install blindly as I might impact other software currently running on the machine. One reason that I'm asking here, instead of searching (which I did) is that most replies were, "use language 'xyz', but you need to use an external SSH connection" - like I'm using Expect in my Perl script. Most also did not agree on what language that 'xyz' should be. ...so, after this long posting, can someone offer some advice?

  • Change kernel used by Ubuntu Server on boot

    - by Tim Fountain
    I have a VPS running Ubuntu server 12.04. A while ago, my host installed an alternative kernel (one of Amazon's EC2 kernels) to fix a boot issue I was having. Now, 2 Ubuntu releases later, this kernel (2.6.31-302-ec2) is still being used even though later (3.2.xx) kernels have been installed. How can I make the server use the most recent installed kernel, preferably without just uninstalling the EC2 kernel just in case doing so causes issues?

  • iptables change destination address base on result from mysql

    - by user1812225
    I need to change destination address of tcp/ip packets based on result of execution mysql query... SELECT `score` FROM `reputation` WHERE `ip` = packet.source_ip if (score < a) then packet.destination_ip = ... else packet.destination_ip = ... What ways of solving this problem do you see? Thanks. P.S. this is important that destination host knows REAL ip address where packet came from, not IP address of firewall.

  • SEO Secrets an SEO Specialist Won't Want You to Know About

    The market place for self claimed 'SEO secrets' is littered with shoddy SEO specialists and cowboys trying to push the common information available to anyone with a computer, internet connection, and a search engine. Here's the breaking news people - there is no secret email that Google sends out to these SEO specialists, and they don't keep a stack of top secret documents back just for the lucky few. It just doesn't work like that.

  • Is there an more user friendly alternative to afraid.org for DNS subdomains?

    - by rogerdpack
    I would like "people out there" to be able to host subdomains to my domain easily. I'm aware that you can do this using afraid.org (free) and it works well, however for "people out there" to use afraid.org is a hard thing because of its cryptic interface (not very user friendly). Any alternatives out there you can recommend, that would allow unlimited subdomains on my domain for whoever wants them, but more user friendly?
