In my experience, it seems that autoconf  needs Makefile.am and configure.ac. How did I do it, I run autoreconf -i -v -f Makefile.am then I did run automake to create Makefile.in then afterwards, I was able to run ./configure successfully.

For my knowledge and guide, sudo scons prefix=/home/hachico/local -j 4 sdl=1 install then this will put the libraries, docs, and bin accordingly into that drectory.

I got the repository from remi for my CentOS. By issuing the following commands: su - cd /etc/yum.repos.d wget http://rpms.famillecollet.com/remi-enterprise.repo  For webtatic, rpm –import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy wget -P /etc/yum.repos.d/ http://repo.webtatic.com/yum/webtatic.repo  where I got my latest versions of PHP. For EPEL and remi, wget http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm Some warned to discourage using the RPMForge because of some conflict with the repository under EPEL. EPEL is known for the repository project for Fedora. For RPMForge, rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm This repos might help you fixing problems on looking for available repository packages.   This repositories are well applied for RHEL and CentOS as

I just stumbled upon with this tesseract where I wasn't able to figure out what's the problem with libtiff since my libtiff, during configure, always says disabled, so I did able to fix it thru ./configure --prefix=/usr --with-libtiff=/usr/lib I tried to let --with-libtiff only, not giving the specific path, but it fails. So specifying the right path, makes the problem fixed. The current version of 2.04 of tesseract, is what I am compiling for this stuff. My libtiff is, indeed, updated using the current version from http://www.remotesensing.org/libtiff. Remember to have the required librarires installed, and these are libpng-dev libjpeg-dev libtiff-dev zlibg-dev leptonica which all of them are separate libraries that you need to install. Leptonica does image analysis and image processing, which is really cool. tesseract use this as it helps them to OCR images. Hope this helps!

There are ways how to do this: awk -F':' '{ print $1 "\t"  $3 }' /etc/passwd That would  print the username and the UID. You can also add the sort command at the end like awk -F':' '{ print $1 "\t"  $3 }' /etc/passwd | sort and this will sort alphabetically. To add filter in the result, you can awk -F':' '$1 == "hachiko" { print $1 "\t"  $3 }' /etc/passwd | sort where hachiko is a username you wanted to print with its UID. Hope this helps!

To create a user, do create user 'myuser' identified by 'iampassword'; To grant a user, do grant select, alter, alter routine, create, create routine, create temporary tables, create user, create view, delete, drop, execute, file, grant option, index, insert, lock tables, process, references, reload, replication client,replication slave, show databases, show view, update, usage on *.* TO 'ipyrusc'@'localhost'; The strings "select, lock, alter, alter routine, etc..." are privileges that you can select to what privilige you want the user created to have. Note that the 'myuser' is specified when granting the priviliges. To assure this user exist, you can do query by select user,host from mysql.user; to show the users of MySQL . To know more about this, check the page about granting and adding a user at MySQL website .

For adding a chain entry:     iptables -A INPUT -p tcp --dport 80 -j ACCEPT     iptables -A INPUT -p tcp --dport 443 -j ACCEPT     iptables -A INPUT -p tcp --dport 21 -j ACCEPT     iptables -A INPUT -p tcp --dport 22 -j ACCEPT     iptables -A INPUT -p tcp --dport 110 -j ACCEPT     iptables -A INPUT -p tcp --dport 143 -j ACCEPT     iptables -A INPUT -p tcp --dport 3000 -j ACCEPT     iptables -A INPUT -j DROP     iptables -I INPUT 8 -p tcp --dport 9999 -j ACCEPT First entry, adds port 80 (http) to be accepted, port 443 (https), port 21 (ftp), port 22 (ssh,scp, sftp), port 110 (pop3), port 143 (imap), port 3000 (custom set port for thin server--a ruby web server). Then, iptables -A INPUT -j DROP  will drop everything that would connect to the server. The last entry iptables -I INPUT 8 -p tcp --dport 9999 -j ACCEPT will insert into the list at the 8 row of the entry, this is useful when you will be setting a specific priority of filtering a port. To delete an entry, you can do,

apxs is an Apachec extension tool. I realize that this tool, is by default, not installed under CentOS (or perhaps even RedHat). To fix this, just install it using yum by: yum install httpd-devel.i386 where apxs is installed under "httpd-devel" package. Hope this helps.
