Ubuntu :: Accessing Parallel Ports From Perl Program
Dec 11, 2010I am trying to write to the parallel port pins from a Perl program running Ubuntu Linux, to light up led's on a bread board. I've already accomplished this on this same box using a C program, but I cannot get my code below to work. I believe the problem is with the line:
$parport = Device::ParallelPort->new('auto:0');
I've tried different variables between the ('') ticks, but nothing has worked. I use Perl on my web pages for forms, but this has stumped me.
Code is below:
#!/usr/bin/perl require "subparseform.lib"; &Parse_Form; print "Set-cookie:
cart_id=1234; user_id=123;
"; print "Content-type: text/html
"; use strict; use CGI; use Device::ParallelPort;
# use Device::ParallelPort::drv; # use Device::ParallelPort::drv::linux # use Device::ParallelPort::drv::parport
# Set up your parallel port object and tell it what driver to use.
#my $parport = Device::ParallelPort->new('auto:0'); print "It works!!!";
Debian :: Build A .deb File Which Will Contain Perl Program?
Aug 18, 2010I'd like to build a .deb file which will contain my Perl program. I just want it to be deployed with dpkg -i on debian systems later. So it's just a matter of having the good arborescence in my .deb package. For that purpose, in the debian/rules file, I'm declaring some dh_install lines in the install rule.
My issue is that I know how to achieve my goal, but only with writing a ton of dh_install lines (one line, for one file...)
example :
clean:
dh_testdir
dh_clean
install: build

Programming :: Unable To Access Filehandles (Perl)
May 17, 2010I've been reading / trying to learn some Perl lately. I've found the free book, "Learning Perl", quite good and easy to follow most of the times. However, today I was testing one of the scripts in the book and it would only run partly.
Code:
#!/usr/bin/perl
use warnings;
use strict;
my %inventory;
[code]....
This row is supposed to give option, either to use an additional script as pipe (sort.plx),or STDOUT if the extra script is not found.It works with the other script present, however, with the sort.plx being absent it simply wont use STDOUT instead but whines to me:
Can't open perl script "sort.plx": No such file or directory
Has the author of the original script done some error writing it? Since I'm a beginner and found most of the stuff confusing in Perl either way (having previously only experience in Bash and some in PHP) - I can't really tell for sure , but from what I can read in documentation - it doesn't appear to be wrong.As it looks now, the only way for me to use STDOUT is only by removing:
open (SORT, "| perl sort.plx") or *SORT = *STDOUT;
select *SORT;
rows. But then, I lose the piping in to that other script as an option.
Programming :: Access A Perl Script Behind A Firewall From Python?
Nov 23, 2010I have a Perl script behind a firewall. I want to access this script from Python on Google App Engine. I have access to the server running the Perl script via the following methods: SSH VPN What are the ways I can do this with Python on GAE? Can I use something like wget, login through ssh and run the script using perl interpreter?
Currently it is a CGI script that I can access through a web browser if I'm inside the firewall. My only other option is to turn the process around, i.e. have perl send data outside the firewall to google app engine. But I want to know if this is possible as it is now without changing the perl script.
Programming :: Perl - Store And Access An Array In A Hash Of Hashes?
Jul 7, 2010I am in need of some syntax help. I'm trying to figure out how to store and retrieve an array out of a hash of hashes. For this example, I'm trying to access the city list for a particular state for a particular country. I understand I could do a join and split on the hash key to combine Country and State, but trying to keep things separated.The code I have gets in all the information for the Countries, and states, and gets the list of cities together, no problem. I store all the city names in an array, then make an anonymous pointer to the array for the hash, like this - $MY_CITIES{$COUNTRY}{$STATE} = [@CITIES]I believe that syntax is correct, or is it? What I'd like to do is I need to cycle through every hash to find if a city exists or not. If it exists in 3 states, then it should print 3 times. Here is the code block to search -
Code:
for $COUNTRY (@LIST_OF_COUNTRIES) {
for $STATE ( keys %MY_CITIES{$COUNTRY){$STATE} ) {

Ubuntu :: What Is The Default Postgres Password?

Ubuntu :: Pgadmin On 10.10 - Support For Postgres 9?
Jan 16, 2011I am in the process of looking to migrate my PC from Windows 7 to Ubuntu 10.10 as I like it and i find it a little quicker than Windows. One of the major failings I find at the moment is software app support. I am setting up some PostgreSQL 9.0 servers (to do streaming replication) and using pgadmin to do the management.
Under Windows this app works great, but under Ubuntu it seems the standard package only supports up to 8.4, and looks like support has been dropped for pgadmin on Ubuntu. What I can't understand is the open source movement isn't supporting itself - or is it that because 10.10 is not on LTS, they are waiting for the next version to update the package - anyone know? If its not supported then back to Windows I go, because I know the latest version works fine.
Ubuntu :: Switch Back To /usr/bin/perl After Installing Second Perl?
Aug 14, 2010I recently reinstalled the B module for perl. Now I found out it didn't just do that, it installed a whole new copy of perl into /usr/local/bin/perl. When I type 'which perl' at the terminal, it says '/usr/local/bin/perl' instead of '/usr/bin/perl'. Normally, this wouldn't bother me. But I installed the one in local/bin without threading support. The one that comes with the system already is build with threading support, which is why I want to switch back to the system perl, and possibly remove the one in /usr/local/bin.
So how do I change it so that the result of 'which perl' returns as '/usr/bin/perl'? And what do I have to do to remove /usr/local/bin/perl?
The reason I need threading support is because I'm designing a file copier that copies several chunks of a file simultaneously to speed up the copying process. Guaranteed a useful script if it works.
Ubuntu :: Postgres Installed But Cannot Find Reference
Mar 24, 2010Just bought a new accounting program BasicBooks - on the install instructions (Gibberish to me) I apparently must have Postgres installed, which apparently comes with most distros. I can't find a reference to Postgres - there should be an entry in 'System Settings --> Server Settings --> Services from the main system menu', which I cannot find. Nor can I find it in the Ubuntu software centre. I did find pgAdmin III but have no idea how this works either.

Your databases are still using the format of PostgreSQL 8.3.
Therefore a backup of the old PostgreSQL server program will be used
until you have saved and removed your old database files

View 15 Replies View RelatedServer :: Restoring A Postgres Database?
Jun 9, 2010We have a disaster recovery solution for our database where a dump file is generated daily at 1:00 AM. We have tested importing the file, along with running another sql file that generates the appropriate database user accounts, into a database on a third-party server.
One question that came up was the following: Suppose the database crashes in the middle of the day, prior to that there were transactions that were entered into the database between the time the dump file was generated, and the crash occurred. We can restore the dump file to either the main or backup server. How can the transactions that were made between the time of the dump file and the crash be restored as well?

Programming :: Getting Shell Script To Execute IF New Row In Postgres SQL Is Added?
Mar 17, 2009I do not want to use cron.I want it to be instantaneous. I am working on a web server where the hosts turned-on safe mode and turned off a-lot of the functions for PHP (including exec) in order to secure their servers. Outside of that, I do have access to chroot and can pretty much do anything on the server. I want to use ImageMagick to create dynamic images based on form data.
I was trying to find a work-around with PHP where I can still use ImageMagick (a shell-based imagining program) by causing SQL to execute a shell script after the form data is saved to a table. Is there anyway it could cause a flag to automatically run a shell script when someone adds a new row to a certain table. It has to be instantaneous, more or less, so that the user isn't sitting there waiting for a minute for cron to catch any changes to the database.
