Fatal error: Call to undefined function: curl_init()

David Dernoncourt — Sun, 15 Nov 2009 11:08:01 +0000

I encountered this message when we enabled upload from URL on Wiki4Games. To solve the problem, you just need to enable curl support in PHP. For Windows, this is done by uncommenting extension=php_curl.dll in php.ini. For Linux (at least in Ubuntu), this is done by installing php5-curl (apt-get install php-curl). Don’t forget to restart Apache (or just “apply changes” in Webmin).

Creating an anonymous FTP with ProFTPd

David Dernoncourt — Mon, 13 Apr 2009 06:32:41 +0000

I’m just posting this as a back up, in fact. This configuration snippet can be used to create an anonymous FTP with read-only privilege in ProFTPd:
##Anonymous for etfiles downloads User www-data Group nogroup # UserAlias -- Alias a username to a system user UserAlias anonymous www-data AllowAll # Cosmetic changes, all files belongs to ftp user #DirFakeUser on ftp #DirFakeGroup on ftp


   RequireValidShell		off
   # Limit the maximum number of anonymous logins

   MaxClients			30
   # We want 'welcome.msg' displayed at login, and '.message' displayed

   # in each newly chdired directory.

   DisplayLogin			welcome.msg

   DisplayFirstChdir		.message

# Limit WRITE everywhere in the anonymous chroot DenyAll AllowAll

Also, adding the following is necessary to prevent the anonymous user from browsing the whole computer:
DefaultRoot ~

Show hidden files with ProFTPD

I used to have no problem displaying hidden files (more precisely, my .htaccesss files) using FileZilla client with ProFTPD, but for some reason suddenly they disappeared… Adding (or editing) the following option in /etc/proftpd/proftpd.conf fixed this:

ListOptions “-a”

(actually I used ListOptions “-al” because the default behavior was -l, which is quite useful to me)

Enemy Territory – shrubbot sample ban and mute

David Dernoncourt — Mon, 12 May 2008 14:03:00 +0000

I’ve always found it hard to make a manual ban or mute when starting a server, because of the lack of a sample ban or mute to put in the shrubbot.cfg file. So here are 2 samples, taken from a shrubbot file for No Quarter (I suppose this should work for ETPub and maybe Jaymod):

[ban]
name = (the player name)
guid = (the guid)
ip = (the IP)
reason = (the reason)
made = (the date and time when ban was issued, for instance: 01/13/07 08:24:00)
expires = (0 = perma ban)
banner = (name of the banner)

[mute]
name = (the player name)
guid = (the guid)
ip = (the IP)
reason = (the reason)
made = (the date and time, for instance: 01/13/07 08:24:00)
expires = (0 = perma ban)
muter = (name of the muter)

Linux command line FTP sender

David Dernoncourt — Mon, 05 May 2008 18:14:00 +0000

Ah, this list of Linux commands is growing for the best
So, a command you can use in scripts or in SSH to simply send a file to an FTP server, without any graphical junk or interface:

ncftpput -t 600 -u $userFTP -p $passFTP $hostFTP /target_path/target_file.name /source_path/source_file.name

You’re welcome

How to get CPU and memory informations on Linux

David Dernoncourt — Mon, 28 Apr 2008 06:15:00 +0000

Today I tried to check some system informations on my server (linux – Ubuntu server 7.10), and I eventually found the following commands:
CPU informations: cat /proc/cpuinfo
Memory informations: cat /proc/meminfo
