Junos OS File Directory and MD5 Checksum

I needed to download the Junos OS used in our MX device.

You can use the file list /var/temp CLI command to check the OS image stored (dir or show bootflash: in Cisco)

admin@junos> file list /var/tmp/

 

/var/tmp/:

Jtac-logs.tgz

LOCK_FILE

To validate the image MD5 checksum, use the file checksum md5 <path/file> command. 

admin@junos> file checksum md5 /var/tmp/junos-vmhost-install-mx-x86-64-2x.4Rx.8.tgz   
MD5 (/var/tmp/junos-vmhost-install-mx-x86-64-2x.4Rx.8.tgz) = 0d02de0cc7aec60825d2dbe513e0af12

Go to the Juniper Software Downloads site, search for the Product, OS and Version. Click Checksums (a hyperlink) to view the MD5, SHA1, etc.

Click the tgz file (a hyperlink), click "I Agree" to proceed.

You can download the OS image locally in your PC or directly to your Juniper device. To download the OS image from your device, just run the file copy <URL destination> command (copy/paste the URL string).
