Using sftp in Junos
You can use sftp to transfer files to and from Juniper devices.
You can initiate the transfer to and from the Juniper device from the Juniper device itself using the command “sftp” from shell:
{master:1} lab@EX4200-VC> start shell % sftp usage: sftp [-1246Cpqrv] [-B buffer_size] [-b batchfile] [-c cipher] [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-R num_requests] [-S program] [-s subsystem | sftp_server] [-JU rt_inst] host sftp [user@]host[:file ...] sftp [user@]host[:dir[/]] sftp -b batchfile [user@]host %
You can transfer any files you want, for instance, the software images.
This is how you can do it.
I have one file on the Linux server that I will copy to the Juniper device:
lab@UBUNTU:/tftpboot$ cat test.txt sdakjfhkajfhksdfhsjghkjsg lab@UBUNTU:/tftpboot$
And this is how you can copy the file using sftp:
% sftp lab@172.30.158.253:/tftpboot/test.txt . The authenticity of host '172.30.158.253 (172.30.158.253)' can't be established. ECDSA key fingerprint is d8:6e:2f:9f:47:ad:74:6f:72:71:0a:51:4e:f9:a0:51. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '172.30.158.253' (ECDSA) to the list of known hosts. lab@172.30.158.253's password: Connected to 172.30.158.253. Fetching /tftpboot/test.txt to ./test.txt /tftpboot/test.txt 100% 26 0.0KB/s 00:00 % cat test.txt sdakjfhkajfhksdfhsjghkjsg %
Although there is not that much use case of sftp because you can use scp, it’s good to know that the command is there and you can use it if you want to.
