PATH
spine path is to be set
rrdtool font is to be set like c:/cacti/arial.ttf

RRDTOOL version must match the installed rrdtool

NIS AUTOMOUNT

1. server: /etc/exports, define exportable directories

/users *(rw,no_root_squash,no_all_squash,sync)
/apps *(ro,sync)

2. server: service nfs restart

3. server: /var/yp/Makefile, edit to include auto.* in make all
(YP server is to be installed first)

4. server: /etc/auto.master :: <--- REMEMBER NO /etc in front of auto.*
/users auto.home --ghost
/apps auto.local --ghost

5. server: /etc/auto.home ::
* -rw dcssrv4:/users/&

6. server: /etc/auto.local ::
oracle -ro dcssrv4:/apps/oracle
gf_admin -ro dcssrv4:/apps/gf_admin

7. server: cd /var/yp;make

8. server: service ypserv restart

9. client: edit /etc/nsswitch.conf :: automount nis files

10. client /etc/sysconfig/network :: put NISDOMAIN=xxxxxxx

11. client /etc/yp.conf :: put domain NISDOMAIN server XXXX

12. client: service ypbind restart & service autofs restart

look at http://penguin.triumf.ca/recipes/nis-auto/index.html
(it has an error, check the instrucion #4 above)

geoframe document errors

1. gf_admin must be of group dba
2. chmod 775 /home/oracle

qemu resize image file

1. qemu-img convert system.qcow -O raw system.raw
2. dd if=/dev/zero of=system.raw seek=N obs=1GB count=0 (N=final size)
3. qemu-img convert system.raw -O qcow growed-system.qcow

QEMU change cdrom

1. start qemu with -monitor stdio option along with other options
2. press CTRL+ALT+2 to enter CLI mode and CTRL+ALT+1 to exit
3. enter command "change cdrom isofilename.iso"

remember you stupid that

files that start with . (dot) in linux will be hidden from plain ls, Gnome deskop,...
