= SSH =

SSH (**S**ecure **SH**ell) is very useful for development on the 825 Gen2.

From a PC on the same network as the 825 you may use a Command Prompt or !PowerShell window and type: "ssh admin@<ip_address_of_825>" to make an SSH connection to the 825. The IP address of the 825 is shown at the bottom of the "APPLICATION MENU". 

The following example makes an SSH connection to an 825 with an IP address of 10.1.2.230
{{{
PS C:\> ssh admin@10.1.2.230
admin@10.1.2.230's password:
card825gen2:~$
}}}

In many network environments it will also be possible to connect by using the hostname instead of the IP address. The hostname can be set after power up of indicator: "Legal metrology information / Setup", "Setup menu", "Communication", "Network", "Hostname". For example, if the hostname is "my825":
{{{
PS C:\> ssh admin@my825
admin@my825's password:
my825:~$
}}}

You will then have access to the terminal to run commands on the 825. For example "free -h" shows information about the 825 RAM memory usage.

{{{
card825gen2:~$ free -h
               total        used        free      shared  buff/cache   available
Mem:           3.8Gi       441Mi       3.2Gi        19Mi       202Mi       3.2Gi
Swap:             0B          0B          0B
}}}


== SCP ==

SCP (Secure Copy) may also be used to copy files between an 825 and PC.

The following example copies the SQLite ID storage database from an 825 to Windows C:\Users\Public directory.
{{{
PS C:\> scp admin@10.1.2.230:/mnt/nand/apps/ids/ids.db3 c:\users\public
admin@10.1.2.230's password:
ids.db3                                                                               100%   48KB   6.6MB/s   00:00
}}}

== SFTP ==

SFTP (SSH File Transfer Protocol or Secure File Transfer Protocol) may be used from the command line to browse directories and files, and copy files between an 825 and PC.

{{{
PS W:\> sftp admin@10.1.2.26
admin@10.1.2.26's password:
Connected to 10.1.2.26.
sftp> cd /mnt/nand/apps
sftp> ls
batcher   chkwgh    hway      ids       mscale    so748240
sftp> cd ids
sftp> ls
bdg.cfg          ids.db3          locrem.cfg       mobile.cfg       scinfo1.cfg      scoreboard1.cfg  scoreboard2.cfg
scoreboard3.cfg  scoreboard4.cfg  tblcfg.dat
sftp> get bdg.cfg
Fetching /mnt/nand/apps/ids/bdg.cfg to bdg.cfg
}}}

A graphical FTP program such as !FileZilla may also be used to browse and copy files between an 825 and PC.
