How can I troubleshoot my Perl CGI script?
(8 answers)
Closed 8 years ago.
I followed my book and I -
1 - Installed Abyss Web server, personal edition.
2 - Copied the book's echo.pl file to the htdocs folder of the webserver. Restarted the
webserver.
3 - Installed Active Perl. (Actually, it was there already. I don't know who put it.)
When I visit the link - http://localhost/echo.pl, I either see the perl file (internet explorer) or download the perl file (chrome). I want this script to handle all requests from my HTML forms. How do I do this ?
Thanks.
I just got lucky. I had no clue what to do. I was wandering in their website to read a bit about them. I wondered who would use this obscure web server when there is apache. Luckily, I saw a section "help & support". There, I saw Scripting languages support and perl was mentioned in the list. I clicked the link and got the instructions for my windows system. Here it is - http://www.aprelium.com/abyssws/perl.html
Download and install Perl
Download ActivePerl from http://www.activestate.com/Products/ActivePerl and install it.
Declare the interpreter
Open Abyss Web Server's console. In the Hosts table, press Configure in the row corresponding to the host to which you want to add Perl support.
If there is no Hosts table in the main screen of your console, this means that you are using an old version of Abyss Web Server. Please upgrade to the latest version before proceeding. Upgrading is free, straightforward, and preserves your current server configuration. Click here to download the latest version.
Select Scripting Parameters.
Check Enable Scripts Execution.
Press Add in the Interpreters table.
Set Interface to CGI/ISAPI.
Note that if you do not find an Interface field, you can ignore this step and continue with the following instructions.
In the Interpreter field, press Browse..., go to the directory where you have installed Perl, click on the bin subdirectory, and click on perl.exe.
Check Use the associated extensions to automatically update the Script Paths.
Press Add in the Associated Extensions table.
Enter pl in the Extension field and press OK.
Press again Add in the Associated Extensions table.
Enter cgi in the Extension field and press OK.
Press OK
Press OK in the Scripting Parameters dialog.
Declare new index files
Select Index Files.
Press Add in the Index Files table.
Enter index.pl in the File Name field and press OK.
Press again Add in the Index Files table.
Enter index.cgi in the File Name field and press OK.
Apply the modifications
Press Restart to restart the server.

Yesterday I went to download MySQL, and I managed to install it, when the download finished, I double-clicked and the program opened normally. I created an account just for testing, so I didn't save the password, so I deleted MySQL to create another account... However when I go to download, now only the option to download in Compressed (zipped) Folder format appears, and I have no idea how to open any type of download in that format, I've tried following the steps taught in the videos and I couldn't either.
Is there a way to fix this? Because yesterday MySQL was downloading normally (as in the image below) and I had no difficulty opening it.
But now the download is just like this (as in the image), and I can no longer open the program.
Note: I use the 64 bit version of Windows 10.
I assume you're downloading MySQL community server from it's official page here: https://dev.mysql.com/downloads/mysql/
If you are, then you can see in the page there are 3 blue buttons
I assume that you are downloading from the "Other Downloads" section (no.2 in image).
could you share the link to the source where you downloaded MySQL?
Usually you should be able to unzip the contents of any .zip file by right clicking the archive in a explorer and choosing extract (not sure what the exact buttons in Windows are called since I don't use it).
Maybe your file got corrupted while you downloaded it (connection issues), have you tried re-downloading it?
I've just searched for the download and started it from the official website
(https://cdn.mysql.com//Downloads/MySQLInstaller/mysql-installer-community-8.0.32.0.msi). This starts the download of an .msi file in my case. Can you confirm that this still starts the download of a .zip file?
I've faced the problem. I use PhpStorm to edit files from FTP server using WinSCP client. In WinSCP client I've set command for using external editor. So, when I try to open php-file from remote FTP server WinSCP downloads this file in temporary file and open it using command provided by me - "C:\Program Files\JetBrains\PhpStorm 2020.1.1\bin\phpstorm64.exe" "!.!"
Earlier, when I used PhpStorm 2019 or 2018, it opened file in already opened window/project. But when I've upgraded to PhpStorm 2020, it started to open file from FTP in separate windows. It's so annoying and some functionality doesn't work in such case (auto suggestions and others).
I know that I can use built-in remote files browser within PhpStorm to view and edit remote files, but I accustomed to use separate FTP client for such purposes.
Does somebody know how to fix this problem? What console command should I use so as to open separate file in already opened window/project?
It's a LightEdit mode: https://blog.jetbrains.com/idea/2020/04/lightedit-mode/
Since 2020.2 you can use the -p (--project) option instead to force opening files in already opened project windows. For example idea -p myfile.txt. IDEA-237118
You can also permanently disable that mode by following these steps:
Invoke Help | Find Action... (or via Search Anywhere: use Double Shift and switch to Actions tab)
Search for Registry... action and select it
Once in the Registry dialog locate light.edit.file.open.enabled entry (just start typing, speed search will narrow it down) and set it to false (uncheck the box).
Not sure if IDE restart is needed (probably not).
Upgraded Telerik in my ClickOnce application to version 2014.3.1202.40. (Never sure of the best way to do this. After the install, all my references to Telerik controls was broken and I had to remove all Telerik references in each of the projects and re-add them. So, I may be upgrading in the wrong way. But that's another matter.)
I deploy my app to a staging folder on my web server before moving to production. The app is signed with a commercial code signing certificate from Comodo that doesn't expire until 2019. I've uploaded new versions many times with no problem. But now, since I upgraded the Telerik controls, I can't download the and install the application. Here's what happens:
In Chrome, I enter the url: http://porpoiseanalytics.com/PorpoiseStaging/setup.exe
I get the "Not commonly downloaded" warning where I never got that before. I don't get any error on Firefox nor on IE.
If I tell Chrome to keep the file, I can start it. The installation starts on all the other browsers too.
About 3/4 of the way through the download of the files, Avast blocks it with DRep virus (I'm guessing lack of reputation). If I turn off Avast, it installs fine. ClickOnce install log shows an error: "Exception occurred loading manifest from file [application].exe: the manifest may not be valid or the file could not be opened."
Why is my application suddenly acting like it has no reputation when it's been downloaded for months with no problems. But, after I modify the application in VS2010 and then remove and re-add the Telerik dll's, I suddenly have no reputation. And what makes matters worse, is that now my production download located at ttp://porpoiseanalytics.com/PorpoiseDownload/setup.exe is suddenly acting the same way.
I admit I don't have a good enough understanding of reputation, signing, and clickonce. But I do know that whereas before we were fine, after deploying the application, we're flagged as malicious software. I made a few code changes in the program (not many), but I also replaced the Telerik dlls. Probably has something to do with signing and publishing, but I can't figure it out. Please help. Thanks.
I think I figured it out. Although I had signed the manifest in the main UI project (the installer), the executable was not signed. With some help, learned how to do that:
Download the Windows 7 SDK with signtool.
In Visual Studio, open project properties in the main UI project.
Open the Compile tab and click on the Build Events button.
In the post-build events, enter:
"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\signtool.exe" sign /f "$(ProjectDir)[name of code cert file]" /p "[password]" /t http://timestamp.comodoca.com/authenticode "$(ProjectDir)obj\$(ConfigurationName)\[exe name].exe
where [name of cert file] is the name of the code-signing cert file, such as private_key.pfk, and [password] is the password used when exporting the certificate (if % is included in the password escape it with %%, so pass%word would be entered as pass%%word), and [exe name] is the name of your primary project executable.
In other projects within solution, sign those by inserting a similar command line in the same post-build location:
"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\signtool.exe" sign /f "$(ProjectDir)DAD_Code_Certificate.pfx" /p "<password>" /t http://timestamp.comodoca.com/authenticode "$(TargetPath)
Orignal Problem
My theory is that the original problem was caused because of a new feature in Avast 2015 that does a DomainRep (reputation?) check and if several criteria are all met, the alarm bells go off and it stops the download. Because my executable was not signed, it met all the requirements.
It is possible (although I really am not sure about this) that because of this DRep alarm, Google flagged the installer on our website as malicious, causing the red "not normally downloaded" warning when first starting the download.
At least, that's my best guess. Others will most certainly understand this better than me (and would have avoided it in the first place by signing the executable).
Official answer from Google Apps technical support (I'm on the Silver support plan - $150/month):
I replicated the issue you are describing and it looks to be a known
issue with Google Chrome, when trying to download an archive that has
an executable in it.
Please be advised that Google Chrome is outside the support scope of
Google Cloud, however the workaround is rather simple: when that
message appears you can click on the arrow to the right of that
message and chose "keep". This will download the file requested.
So I was using sublime-text 2 to modify some php files held on a remote server. I used nautilus sftp://... address to server to open up the folder then clicked on the files and pressed open with sublime text. Whenever I did this it automatically saved the changes on the server. For various annoying reasons I had to restore the machine to factory settings. Now whenever I try to open up the files in the way I use to be able to it just opens a blank file titled sftp in my /user/dev directory. Is there anything I need to do to get it back to the way it used to be?
Not sure anyone else has ever experienced this behavior but I never replicated the nautilus effect that I had originally. The best alternative I found was sublime sftp.
Installed by sublime package control:
https://sublime.wbond.net/installation
Then install sublime sftp:
http://wbond.net/sublime_packages/sftp
I was a student coding in php for a class so I was only using it temporarily and never paid for the license. Probably should do that if you are gonna be using it long term.
I am trying to make a webpage which will have the entire inventory of servers that our team manages in the form of a table. I am using a simple LAMP stack and the inventory input as a CSV file.
The table has three columns: Hostname, IP address and device serial number.
While this works perfectly fine, I want to take this a step further and make every IP address in the table a hyperlink, clicking which will open an SSH client, which will connect to that IP address. Any cues to how this can be done? I was hoping there would be something like the the mailto: tag which opens an email client (Outlook window).
I've done it following the info of this blog post.
For future reference in case the original page becomes missing, here is the process:
you cannot directly map the ssh:// scheme to PuTTY, but you can map it to an intermediary script which will in turn launch PuTTY with the right arguments. Mine is called putty_ssh.bat and has the following content:
#echo off
set var=%1
set extract=%var:~6,-1%
start "C:\Program Files (x86)\PuTTY\putty.exe" %extract%
the script has to be registered in the registry. You can just create a ssh.reg file with the following content and open it (customizing last line as needed):
REGEDIT4
[HKEY_CLASSES_ROOT\ssh]
#="URL:ssh Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\ssh\shell]
[HKEY_CLASSES_ROOT\ssh\shell\open]
[HKEY_CLASSES_ROOT\ssh\shell\open\command]
#="\"C:\\path\\to\\putty_ssh.bat\" %1"
When I click on ssh:// links in web pages, it now opens PuTTY.
PuTTY unfortunately does not associate itself with the ssh:// or any other URLs.
You can associate an application with a protocol manually. But it's not trivial. For instructions, see below.
Easier way is to install WinSCP SFTP client. WinSCP 5.9 and newer registers itself to handle the ssh:// URL and opens the session specified by the URL in PuTTY.
So basically, if you just install WinSCP, it will make PuTTY handle the ssh:// URLs, without the below manual tweaks.
(I'm the author of WinSCP)
To register an application manually, see the MSDN article Registering an Application to a URI Scheme.
Basically you add a registry key like:
[HKEY_CLASSES_ROOT\ssh]
#="URL: SSH Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\ssh\DefaultIcon]
#="\"C:\\Program Files (x86)\\PuTTY\\PuTTY.exe\",0"
[HKEY_CLASSES_ROOT\ssh\shell]
[HKEY_CLASSES_ROOT\ssh\shell\open]
[HKEY_CLASSES_ROOT\ssh\shell\open\command]
#="\"C:\\Program Files (x86)\\PuTTY\\PuTTY.exe\""
Though the above passes a whole URL to the PuTTY command-line. And PuTTY does not understand the ssh:// prefix. So you would have to add a wrapper script that strips the ssh:// and passes only a user and a host to PuTTY.
For that see:
