JunOS - mount USB stick

By -
There are times when you have to use a USB stick to copy to or from it files to a Juniper router/switch.
Fortunetly it will not be to very frequently, but there will be a time when you will need it.
JunOS being a UNIX( FreeBSD ) based OS, you have to identify and mount the device attached.
First, you have to check the device name, so you can identify it on /dev:
smocanu@j2350> show log messages | match mass
May 16 15:25:45  j2350 /kernel: umass0: Kingston DataTraveler SE9, rev 2.00/1.00, addr 2
May 16 15:25:46  j2350 /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Then you have to verify the partition number, usually it is the first one:

smocanu@j2350> start shell
% ls -las /dev/da0
/dev/da0 /dev/da0s1
Now you can mount your USB stick:

% mkdir /var/tmp/usb
% mount_msdosfs /dev/da0s1 /var/tmp/usb

Once your USB stick is mounted, you can copy to/from it files, using /var/tmp/usb path.

Do not forget that you have to umount the USB storage, before removing it from your device.

% umount /var/tmp/usb/
% exit

SSH: Generating and using SSH keys

By -
Image
One of the preferred method of authentication on network devices is using SSH with a SSH public key. In order to be able to authenticate yourself, you have to generate a SSH key pair. A SSH key is composed of two parts, one private key (which should remain "private" and also should be password protected ) and one public key which should be installed on the SSH server in order to authenticate you. SSH client on Linux: In order to generate a SSH key pair on Linux, you will need to use "ssh-keygen" tool, which is a part of the "openssh-client" package on Debian-like operating systems: smocanu@debian7:~$ dpkg -S $(which ssh-keygen) openssh-client: /usr/bin/ssh-keygen or a part of "openssh" package on RedHat-like operating systems: smocanu@centos6 ~$ rpm -qf $(which ssh-keygen) openssh-5.3p1-94.el6.x86_64 The generating process is quite simple, just run the "ssh-keygen" command, and it will ask you the location of the new key ...

JunOS - loging on secondary node of a cluster and copying file between nodes

By -
First at all you have to know that you should be able to login to a secondary node of a J/SRX cluster using OOB( out of band management interface - fxp0 ), but, if this is not possible you can do it from the primary node. In my case there is a cluster of SRX240H2. You have to login into the cluster and check the status of it: smocanu@srx240h2# run show chassis cluster status Cluster ID: 1 Node                  Priority          Status    Preempt  Manual failover Redundancy group: 0 , Failover count: 1     node0                   100         primary        no       no     node1     ...
