 Start the ftp server. It should be loading the firmware.

Disposable Linux TFTP Server

Whenever we talk about a server, always it need not be highly configurable.

I was looking for a simple tftp server to upgrade phone firmware. Either it comes with xinetd or service related things with all unwanted security settings etc..

Would you argue what is safe?

I just need a standalone executable to serve files via tftp and dispose it off. Not as a installed service or xinetd crap.

tftpgui under linux did a pretty awesome job.

Run in the  command line  

kans@kansmac14 ~/Downloads/tftpgui $ sudo ./tftpgui.py

You are given a simple UI to select the folder to serve file and logging.

Pretty Simple and Awesome ! Simple Engineering need to be Simple.

Cisco 7975G / 7975 into trouble again

I want to change my SIP proxy (asterisk) from my router to my QNAP NAS.
Had to configure tftp with the right config on xmls.

Awesome tftpd-ha setup made me a round trip.

/etc/default/tftpd-ha - need to be configured with right user and the root folder should be with the correct permissions.

TFTP_USERNAME="root"
RUN_DAEMON="yes"
OPTIONS="-l -s -c /home/username/Downloads/test"
TFTP_DIRECTORY="/home/username/Downloads/test"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"

Make sure you have dhcp options 150 set with right IP Address.

Again I'm pleased with the voice and mic quality of Cisco Phone !

 

Installing a Laser Printer on Linux

HL2270DW - Brother Laser Printer Installation in few seconds. No drivers to Install

Used the URI I used was: ipp://$IP/pcl_p1 and the driver I chose was "Generic PCL Laser Printer" with the Duplex option checked. And it's worked perfectly since then!! How awesome is that.
