The beauty of Juniper JUNOS
I'm actually a Cisco/Unix geek. But I'm working on some giant Juniper routers now a days. The beauty of Juniper router opearting system (JUNOS) is, indeed, based on FreeBSD. Upgrading opearting system is my favorite things, because I love impressive new features. I come from a unix background where such a thing is easily allowed. I'm gonna write a way how to fill USB devices with Junos software.
In Next Generation RE, upgrade from USB devices is available. You must have at least RE-A-1000 or RE-A-2000 to perform upgrade from USB devices.
Below is the simple manual:
The device name is /dev/rda0 instead of /dev/rad3.
jahil@jahil> start shell
Log into directory where the install media file is (ie: /var/tmp/)
jahil@jahil% cd <directory>
Issue the following commands:
jahil@jahil% dd if=/dev/zero of=/dev/rda0 count=20 ; initialize the media
jahil@jahil% dd if=install-media-9.1R2.4-export of=/dev/rda0 bs=64k ;
