| Optional Support
|
- We do NOT provide FREE "howto support"
- due to the nature of the wansim product, it is assumed the user knows enough about network simulations and network emulations and associated wansim technology, process and proceedures
- However, for those that require handholding, we provide Professional Consulting as required
( see our entry for Linux-Consulting.com )

| Booting FreeBSD-8.x to Fix gigEnn
|
- To Fix gigEnn :
- you can always burn a free freebsd CD -- or --
- burn a bootable FreeBSD usb stick
- ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/8.1
- ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/8.0
- Once you have booted FreeBSD off your CD or USBstick that runs in memory ...
- Let's assume your gigEnn-T3 wansim is at 192.158.1.101
- Let's assume your gigEnn-T3 wansim is /dev/ad2 ... ( from dmesg )
FreeBSD# mkdir /mnt/CF2
FreeBSD# fsck /dev/ad2s1a
FreeBSD# fsck /dev/ad2s2a
FreeBSD# mount 192.168.1.101:/usr.rw /mnt/CF2
FreeBSD# rm -rf /mnt/CF2/etc/wansimconf /mnt/CF2/..License.Agree.txt
FreeBSD# mkdir /mnt/CF2/etc/wansimconf ; chown wansimconf /mnt/CF2/etc/wansimconf
FreeBSD# umount /mnt/CF2
FreeBSD# reboot

- gigEnn-T3 uses a standard Power Adaptor
- +12v to +18v DC, 800mA
- 2.1mm center positive power pin
- Interchangeable international power adaptor -- extra charge ..
- International customers would be using their own local power adaptor
- usa power supply plus country specific ( eu, uk, au, kr, cn .. ) adaptor
- Remote ssh login to wansim fails :
- ssh_exchange_identification: Connection closed by remote host
- wansim> sudo vi /etc/hosts.allow
Add the ip# of your host to the sshd: line
- wansim> sudo /etc/rc.d/inetd restart
- the wansim does NOT boot because:
- please verify the power cord is plugged all the way into the wansim
- the CF was somehow corrupted
- if the wansim doesn't boot... you will need another FreeBSD machine to fix the dead gigEnn wansim
- Manually update the wansim
- you should use the "Online Update" option from the wansim gui
- wansim> sudo gigEnn.update.sh -install -rootfs
#
# Lets say the latest downloaded image was: 2011.1125.img.gz
#
- sudo fsck /dev/ad0s1a
- sudo mount /dev/ad0s1a /mnt/CF
- sudo cp -p /mnt/CF/usr/tmp/2011.1125.img.gz /mnt/CF/boot
- sudo cd /mnt/CF/boot && mv mfsroot.gz mfsroot.2010.xxyy.img.gz
- sudo cd /mnt/CF/boot && ln -s ./2011.1125.img.gz mfsroot.gz
- sudo cd ; sync
- sudo umount /mnt/CF
- wansim> sudo gigEnn.update.sh -install -kernel
#
# Lets say the latest downloaded kernel was: kernel-i586.2009.1117.tgz
#
- sudo fsck /dev/ad0s1a
- sudo mount /dev/ad0s1a /mnt/CF
- sudo cd /mnt/CF/boot && mv kernel kernel.2010.xxyy
- sudo cd /mnt/CF/boot && tar zxvfp /usr/tmp/kernel-i586.2009.1117.tgz
- sudo cd /mnt/CF/boot && ln -s ./kernel-i586.2009.1117 kernel
- sudo cd ; sync
- sudo umount /mnt/CF
- default gateway doesn't work
- the default gateway ip# must be in the same ip# range/mask as used for mgmt0, net1 or net2
- gigEnn-T3 users might encounter the "disappearing user defined parameters" ( /usr.rw )
#
# this usually occurs when the power plug is pulled as opposed to a proper shutdown from the wansim menu
#
# unfortunately, in order to support some new features such as:
reset to factory defaults, saving user test parameters, saving resulting runtime test data,
the user can no longer just pull the power plug which is a bad practice in the first place
- Please properly shutdown with the Shutdown/Halt option in the wansim gui
- To Fix the /usr.rw corruption problem
- Check if /usr.rw is displayed
- drop to shell from the main wansim gui menu
- > df
#
# if /usr.rw is listed, you have a different problem
# if /usr.rw is NOT listed, you will need to fix the disk corruption ( see below )
- Fix the corrupted disk partition
( scandisk in microsoft terminology )
- > sudo fsck /dev/ad0s2a
#
# answer "y" to the question fsck is asking to fix itself
#
- Reboot for the quick and dirty test for the impatient
- Mount and verify the fix
#
# mount the previously corrupted disk partition that was fixed
- > sudo mount /dev/ad0s2a /usr.rw
#
# check that /usr.rw is mounted
- > sudo df
# -- if /usr.rw is listed ... the problem is solved ..
# -- if /usr.rw is NOT listed ... you have a different problem ..
#
# check your data
- > cat /usr.rw/etc/wansimconf/net-config
#
# all done, just reboot properly
- > sudo reboot
