OpenSSH Configuration and Usage Part 3
Hi guys I hope you enjoyed both parts of SSH this is the final part of SSH which is based on SFTP. In this tutorial we will cover how to use SFTP commands we have already discussed how to configure SFTP server in our previous tutorial. In this tutorial we will learn how to use ls,lls,pwd,lpwd,mkdir,rmdir,put,get,mput and mget commands
SSH File Transfer Protocol
A network protocol that provides file transfer and manipulation functionality over any reliable DataStream. It is typically used with the SSH-2 Protocol to provide secure file transfer. (Intended to be usable with other protocol as well)
Capabilities
The SFTP allows for a range of operations on remote files. SFTP Client’s extra capabilities compared to SCP client including;
- Resuming interrupted transfers
- Directory listings
- Remote file removal
For the same reason it is reasonable to implement a GUI SFTP client, but not a GUI SCP client.
Log on using SFTP
We want to log on to sftp by using command sftp. Syntax sftp username@hostname/IP
[Server@faraz ~]$ sftp [email protected] [email protected]'s password: Connected to 192.168.56.103. sftp>
Commands on remote/local System
Once you are logged on to the remote system, normal commands run and will responds you for the system on which you are logged on (Remote system). For issuing commands for local system put “l” (small L) before any normal commands.
List contents of remote system by using command ls.
sftp> ls Desktop Documents Download Downloads Music Pictures Public Templates Videos historysave.txt newstring.file ssh.config testfile.txt sftp>
List contents of local system by using command lls.
sftp> lls lls 1234 Downloads historysave.txt Pictures testfile.txt Desktop testf Music Public Videos Documents newstring.file Templates sftp>
To check present working directory on remote system by using command pwd.
sftp> pwd Remote working directory: /home/Client sftp>
For local system to check working directory by using command lpwd.
sftp> lpwd Local working directory: /home/Server sftp>
Change directory on remote system by using command cd.
sftp> cd Documents/ sftp> pwd Remote working directory: /home/Client/Documents sftp>
For local system change directory by using command lcd.
sftp> lcd Desktop lcd Desktop sftp> lpwd Local working directory: /home/Server/Desktop sftp>
Make directory on remote system by using command mkdir and for remove directory by using command rmdir.
sftp> mkdir test123 sftp> ls Desktop Documents Download Downloads Music Pictures Public Templates Videos historysave.txt ssh.config test123 testfile.txt sftp> rmdir test123 sftp> ls Desktop Documents Download Downloads Music Pictures Public Templates Videos historysave.txt ssh.config testfile.txt sftp>
Upload file from local system to remote system by using command put.
For multiple files use mput. Syntax mput *.txt/*.pdf (do it yourself).
sftp> ls Desktop Documents Download Downloads Music Pictures Public Templates Videos historysave.txt newstring.file ssh.config testfile.txt sftp> lls Desktop Downloads Music Public upload.txt Documents Faraz Pictures Templates Videos sftp> put upload.txt Uploading upload.txt to /home/Client/upload.txt upload.txt 100% 217 0.2KB/s 00:00 sftp>
Now want to download file from remote to local system by using command get. For multiple files use mget. Syntax mget *.txt/*.pdf (do it yourself).
sftp> get newstring.file get newstring.file Fetching /home/Client/newstring.file to newstring.file /home/Client/newstring.file 100% 76 0.1KB/s 00:00 sftp> lls Desktop Downloads Music Pictures Templates Videos Documents Faraz newstring.file Public upload.txt sftp>
Now I want to close the session from sftp by using command exit or bye.
sftp> exit exit [Server@faraz ~]$
I hope you enjoyed SFTP commands and now you must be comfortable using sftp . There are so many tools with GUI to upload and download files local/remote systems like FileZilla, FireFTP etc. Feel free to explore these GUI tools.
