| I'm not sure if my stuff is really research, but this is some of the stuff that I'm busy with:

| == Installing cacti on FreeBSD ==
| |
| | |
| Recipe to install FreeBSD, add ports mysql, php5 and cacti:
| |
| http://wirelessafrica.meraka.org.za/wiki/index.php/Image:Installing_Cacti_on_FreeBSD.zip
| |
| | |
| If you intall it for the first time,
| |
| you may have to follow this steps to make it work correctly:
| |
| | |
| 1. Create the MySQL database:
| |
| # mysqladmin --user=root create cacti
| |
| 2. Create a mysql user/password for cacti:
| |
| (change user and/or password if requered)
| |
| # echo "GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactiuser'; F LUSH PRIVILEGES;" | mysql
| |
| 3. Import the default cacti database:
| |
| # mysql cacti < /usr/local/share/cacti/cacti.sql
| |
| 4. Edit /usr/local/share/cacti/include/config.php.
| |
| 5. Add a line to your /etc/crontab file similar to:
| |
| */5 * * * * cacti /usr/local/bin/php /usr/local/share/cacti/poller.php > /dev/nu ll 2>&1
| |
| 6. Add alias in apache config for the cacti dir:
| |
| Alias /cacti "/usr/local/share/cacti/"
| |
| 7. Be sure apache gives an access to the directory ('Allow from' keywords).
| |
| 8. Open a cacti login page in your web browser and login with admin/admin.
| |
| | |
| Add the following line in the end of httpd.conf
| |
| vi /usr/local/etc/apache22/httpd.conf
| |
| Include etc/apache/Includes/*.conf
| |
| | |
| vi /usr/local/etc/cacti.conf
| |
| Alias /cacti/ "/usr/local/share/cacti/"
| |
| <Location /cacti>
| |
| AddHandler php-script php
| |
| DirectoryIndex index.php
| |
| AllowOverride None
| |
| Order allow,deny
| |
| Allow from all
| |
| </Location>

| OK, finally get around to it. First read John's info on the wiki: http://wiki.meraka.csir.co.za/wiki/index.php/Category:ASUS_eeePC
| |
| | |
| Then copy John's FreeBSD EeePC distribution (img.tgz) to my PC. Follow Werner's instructions to get the distro on USB memory stick
| |
| | |
| fdisk -I da0
| |
| fdisk -B da0
| |
| bsdlabel -w da0s1 auto
| |
| bsdlabel -B da0s1
| |
| newfs /dev/da0s1a
| |
| mount /dev/da0s1a /mnt
| |
| tar -xvf img.tgz -C /mnt/
| |
| echo /dev/da0s1a / ufs rw 1 1 > /mnt/etc/fstab
| |
| echo ifconfig_DEFAULT=DHCP > /mnt/etc/rc.conf
| |
| echo hostname=demo >> /mnt/etc/rc.conf
| |
| umount /mnt
| |
| | |
| Plug into USB port on EeePC. Select boot form USB (Press ESC at bootup to get menu) Boot FreeBSD Dump WinXP image on a USB disk
| |
| | |
| dd if=/dev/ad2 of=/dev/da2 bs=4k
| |
| | |
| Follow instructions above to get FreeBSD on ad2
| |
| | |
| fdisk -I ad2
| |
| fdisk -B ad2
| |
| bsdlabel -w ad2s1 auto
| |
| bsdlabel -B ad2s1
| |
| newfs -U /dev/ad2s1a
| |
| mount /dev/ad2s1a /mnt
| |
| tar -cf - --exclude /mnt / | tar -xvpf - -C /mnt
| |
| echo /dev/ad2s1a / ufs rw 1 1 > /mnt/etc/fstab
| |
| | |
| Enable ipv6, ssh and moused in /etc/rc.conf
| |
| | |
| ipv6_enable="YES"
| |
| sshd_enable="YES"
| |
| moused_enable="YES"
| |
| | |
| Shutdown and reboot.
| |
| | |
| Install Xorg and KDE
| |
| | |
| setenv PACKAGEROOT ftp://ftp2.za.freebsd.org
| |
| pkg_add -r xorg
| |
| pkg_add -r kde-lite
| |
| | |
| Enable and test sound. Add the following line in /boot/loader.conf
| |
| | |
| snd_hda_load="YES"
| |
| | |
| | |
| Search for app that can show the battery status in X. Install and test desktopbsd-tools. Battery status works. Test wifi install gui. Not impressed, it only supports WEP
| |
| | |
| pkg_add -r desktopbsd-tools
| |
| | |
| Battery status works. Test wifi install gui. Not impressed, it only supports WEP. Delete package and search for other battery apps. See that KDE has a package that can show battery status. Install klaptopdaemon.
| |
| | |
| pkg_add -r kdeutils-klaptopdaemon
| |
| | |
| Battle to get it to work. Eventually find out that you have to load AMP (advanced power management). Edit /etc/rc.conf and add the following lines.
| |
| | |
| amp_enable="YES"
| |
| ampd_enable="YES"
| |
| | |
| Shutdown and reboot
| |
| | |
| Login and start KDE. Enable battery monitor under kde "Start" "Settings" "Power control" "Laptop Battery". Yes, I get a new battery icon. Remove power and test it. Battery shows power, but reporting of "time left" is broken.
| |
| | |
| Enable power manager to preserve power while running on battery. Add following to rc.conf
| |
| | |
| powerd_enable="YES"
| |
| | |
| and lower CPU speed. Add the following to /etc/sysctl.conf
| |
| | |
| dev.cpu.0.cx_lowest=C3
| |
| | |
| Try to get dstumbler to work so that we can use the EeePC as a wireless measurement PC. Install BSD-airtools (dstumbler part of it), but it looks like the package is broken. Search for other packages that we can use, but I can't find anything. Start looking at what command line stats available.
| |
| | |
| Try to enable virtual screen resolution in Xorg. Add the following in the Screen section of xorg.conf
| |
| | |
| SubSection "Display"
| |
| Viewport 0 0
| |
| Depth 24
| |
| Virtual 1200 720
| |
| EndSubSection
| |
| | |
| Restart X, but it doesn't work. Do a lot of reading and playing, but I cannot get it to work.

| == Meraka wireless Network ==
| |
| We are making use of Linksys WRT54 wifi routers, re-flashed with dd-wrt software. We've also enabled WPA corporate mode, using a Radius server that verify users against the CSIR LDAP server.
| |
| | |
| ====Upgrading the dd-wrt firmware on a linksys.====
| |
| Firmware upgrades are usually done via the WEB gui. Here is the instructions to do it on the command line. It's important to know how to do it, so that we can script it in future. Fist enable ssh via the WEB gui. You can find it under Administrator -> Services -> Secure Shell. Select SSHd en then add your ssh public key under the Authorized Keys section. Save settings. Now you can login without a password as well run remotes commands via ssh.
| |
| | |
| scp ftp/linksys/dd-wrt/dd-wrt.v24_std_generic.bin root@192.168.1.1:/tmp
| |
| ssh root@192.168.1.1 "write /tmp/dd-wrt.v24_std_generic.bin linux"
| |
| ssh root@192.168.1.1 reboot
| |
| | |
| Load WEB gui and verify if upgrade worked. Yes - all new.
