I’ve been trying to install mysql50-server via ports, but have been getting a checksum error, like this:

For an easy fix, all I did was fetch the mysql tar from freebsd.org and place in /usr/ports/distfiles/, intalled again through the ports, and voila!!

Here’s an easy one liner fixer (for the lazy people, like me). Just copy and paste at prompt.

NOTE: This is all one line.

Done!!

Here’s a quick and easy way to redirect a domain name to a specific page using mod_rewrite.

This uses a 301 Permanent Redirect to the redirected page.

Do you need to download a text file instead of having your browser read the file?

All you need to do is use the code below, and name it download.php (or whatever you want).

NOTE: Make sure you copy as is and do NOT leave any whitespace since you are sending headers.

All you need to do is replace filename.txt with the name of the filename you wish to have downloaded.

Now create another file, index.html perhaps, and just link to that php file, and you are all set. If you named the script download.php, you will just need:

Done!!

Do you see ^M at the end of every line? Or ^M at random places where a new line should be?

This seems to happen when a DOS or Windows machine edits a text file. It is the Control Character for Carriage Return. To remove this, you will need to edit the file in Vi. Not sure how to do this in other text editors, but this will definitely work in Vi.

If you want to just remove the ^M characters, run this command in Vi:

NOTE: Do not type Shift-6, Shift-m. That will not work. You will need to hold down ctrl while pressing V then M.If you want to replace each ^M character with a new line, run this command in Vi:

Again, hit ctrl-V-M to issue the second ^M in the replacement field.

Done!!

So you want to mount a network drive with Samba?

First thing you do is install Samba via ports on both systems. (Be sure to update your ports with cvsup, that will be in a future article)

Next, on the server machine, in order to make Samba run, you will need to add it to /etc/rc.conf. Just add this line:

On the client machine, you don’t have to start Samba. In fact, for added security, I remove the samba.sh startup script like so:

Now we add the user on the server machine. You will be adding an actual Unix user, but without a login and home directory.

Username : SambaUser
Password : *****
Full Name : Samba User
Uid : 1004
Class :
Groups : SambaUser
Home : /dev/null
Shell : /usr/sbin/nologin
Locked : no

Add a Samba password:

Now we edit the Samba service in smb.conf located at /usr/local/etc/smb.conf with…

Be sure to create the directory (/path/to/directory) and make that writable to the SambaUser.

To test your server, you should be able to do this:

If no errors, then you are good to go. If you get an error, please refer to Samba’s site, or you can google the error message.

We can start Samba now with this:

Now we mount the drive. Create the directory in the client machine where you would like the mounted network drive at, and then mount it. (NOTE: Below is all one line)

That’s pretty much it!!

Done!!

So you want to reinstall PHP??

This is how you would reinstall php, for whatever reason, and keep the same config options.
First of all, you need to find out what ./configure options you used to install PHP in the first place. Go to the source folder, usually /usr/local/php-(version number). Open up config.status in your favorite editor and copy the ./configure line, which is probably at or around line 7.

Change directory into the PHP source folder. Run a clean, distclean, patch (if needed), configure (with the same options as in the config.status file), make, install, and finally restart apache.

Done!!

OK..Roll up your sleeves. It’s time to get dirty (not as dirty as installing KDE via ports though). So here we go.

I’m just going to talk about post-installation. Yeah, yeah, I’ll get to the install later. Anyway, the first thing I install is cvsup. You can install this via ports:

I installed cvsup-without-gui because, well, I never actually used just cvsup.

After it installs, it will create a ports-supfile file at

or

Just copy it to your root folder. Then, just change

to a cvsup server near you. To find a cvsup server near you, just go to

After that, run cvsup:

Oh yeah, if you are behind a firewall, make sure to open port 5999.

Done!!
