CHAPTER 7 UPGRADES AND TROUBLESHOOTING
Upgrades
All 6 files added by Cyclades to the standard Linux files are in the /proc/flash directory. They are:
boot_ori - original boot code
boot_alt - alternate boot code
syslog - event logs (not used by Linux)
config - configuration parameters, only the boot parameters are used by the boot code
zImage - Linux kernel image
script - file where all Cyclades-TS configuration information is stored
To upgrade the Cyclades-TS, proceed as follows:
A) Log in to the TS as root (provide the root password if requested)
B) Go to the /proc/flash directory using the following command:
cd /proc/flash
C) Ftp to the host where the new firmware is located, log in using your username and password, go to the
directory where the firmware is located, select binary transfer and “get” the firmware file. NOTE: the destination
file name in the /proc/flash directory must be zImage. Example (hostname = server; directory = /tftpboot; username
= admin; password = adminpw; firmware filename on that server = zImage.132):
ftp
> open server
> user admin
> Password: adminpw
> cd /tftpboot
> bin
> get zImage.132 zImage
> quit
