How to Copy local files to remote host with SCP
$ scp file user@host:path
Host :- can be IP address or hostname of remote system
: (colon) :- helps scp to identify remote host
Username:- on remote host
SSH cardinal or password :- is required to copy file using scp
Path :- Absolute or relative path for local file or directory
For example -
$ scp examination.txt user1@ubuntu:/tmp
Re-create Remote file to local host
$ scp user@host:file path
How to Copy directories to local host using SCP
$ scp -r user@host:directory_path path
Copy file between two remote hosts
$ scp user1@host1:file1.txt user2@host1:directory_path
Now when you know, what are basic scp commands. Time to know about public key hallmark-
SCP requires a password to authenticate to the remote organisation. Simply in case you desire to avert information technology or using SCP in scripts, Public central is required.
Basically, you lot generate a public-private key pair on the client (local) and copy the public fundamental to a remote system (server) into the authorized key.
To make you empathize scp commands hands, i have shared my LAB details
Lab setup details -
Local server proper noun - Server1 (Ubuntu eighteen.04)
Remote server name - Server2 (Ubuntu 20.04)
Source file - /test/file1.txt
Target directory - /remote-test
username - dev
SCP permission denied issue
Scenario1-
I am trying to re-create /test/file1.txt from server1 (local) to server2 (remote) in /remote-exam directory. I am also getting permission denied.
$ scp "local-file" "user@remote-host:/path-to-remote-dir"
Reference output
To resolve these mistake - perform below mentioned steps-
Solution ane :- Double check your user and password
Delight make certain, you accept mentioned correct username and password in the command. This is one of the very bones mistakes, we do. So, you lot tin try writing your password in notepad, copy and paste it in control prompt. When asked during SCP command.
i have validated username and password is correct in my instance.
Solution 2 :- Bank check for remote path
Make sure, the path you lot take mentioned as the remote directory is right. For example, in my case /remote-test is the remote directory and information technology's right.
Solution 3 :- Check for Read write access on remote directory
Double-bank check, whether your user mentioned in command take read-write (RW) access on the remote directory. For case, in my case " /remote-dir " must-have RW access to user "dev".
Follow these steps to check -
-> Login to remote system (server2)
-> Run "ls" -ld command to check permissions of /remote-dir .
$ ls -ld "your-remote-dir"
Reference output
Then, if you volition see in epitome, /remote-dir merely allows read, write and execute (rwx) permission to root user only. For group and others, information technology has read and execute (r-x) permission. So my user "dev" will be treated every bit other, and it won't be able to write. Every bit a event, I am getting SCP permission denied error.
-> At present to resolve this error, assign Read-write-execute (rwx) permission to everyone.
$ sudo chmod 777 "path-to-your-remote-directory"
Reference output
-> Run scp command once more
Warning
Setting 777 permission on whatsoever directory is not secure. So once yous are able to isolate the "SCP permission denied" issue. Either alter ownership and set permission to 755.
If yous are nonetheless facing permission denied error, move to next pace
Solution 4 :- ownership issues (directory should exist owned by user)
-> Login to your remote system (server2)
-> Modify ownership of your remote directory for your user. For case, I volition change ownership of /remote-dir to my user "dev" instead of "root".
$ sudo chown -R dev:dev "path to your remote directory"
Reference output
-> Run scp command and it must piece of work for yous
Solution 5 :- Diagnose problem with scp -v command
Try to use -v (verbose) option to diagnose the issue with scp command.
For example
$ scp -v /test/file1.txt dev@192.168.126.129:/remote-dir output truncated - debug1: Sending environment. debug1: Sending env LANG = en_IN debug1: Sending command: scp -v -t /remote-dir Sending file modes: C0644 0 file1.txt Sink: C0644 0 file1.txt scp: /remote-dir/file1.txt: Permission denied
Check message after scp -v -t command, if it shows permission denied, Follow solution 3 or 4 as described in the post. it will resolve your effect.
Solution vi :- Validate option -P is used for port not -p
When running SCP command Option -P is used to mention custom port, in case default port TCP 22 is not used. Sometimes, instead of -P, we use -p (lowercase) by mistake. For better understanding permit me tell you the difference between these 2 -
- -p (lowercase):- Preserve access, modification and modes from the original file.
- -P (upper-case letter):- Specified customize port to connect remote host.
For case port 2314 is custom port instead of 22.
$ scp -P 2314 dev@192.168.126.129:/remote-dir/file1.txt /test/
SCP permission denied (publickey) - AWS EC2 instance
Scenario ii-
Try beneath mentioned solution, in case of SCP permission denied (publickey) with AWS ec2 instance -
If you have set up password-less authentication or you have permission key with y'all to authenticate remote organization, you may come across this error.
Take a check from Solution 1-vi mentioned in the mail, if it doesn't help motion further -
Solution 7 :- Utilise -i option and provide ".pem" private key always
When you use SCP and don't use -i selection. It uses default ssh key under (~/.ssh/) directory. So always use -i selection and provide the path to ".pem" cardinal file.
For example "ubuntu.pem" is central file in my case.
$ scp -i ~/Desktop/ubuntu.pem ~/Desktop/test/code/www/alphabetize.html dev2@server:/var/www Solution viii :- if using permission central SSH is working simply not SCP
If y'all are able to ssh to the remote host using -i option and not able to scp. It means you are hitting a issues.
So instead of using -i "path to .pem file"
$ scp -i ~/Desktop/ubuntu.pem ~/Desktop/examination/code/www/index.html dev@server2:/var/www use -o "IdentityFile" selection.
$ scp -o IdentityFile ~/Desktop/ubuntu.pem ~/Desktop/test/code/world wide web/index.html dev@server2:/var/world wide web Solution nine :- Endeavor removing your host entry from "known_hosts" file
Erstwhile, there may be issue due to onetime or wrong host key. Delete that particular host from know_hosts file using editor or command as follows.
$ ssh-keygen -R hostname or $ vim ~/.ssh/known_hosts Oftentimes Asked Questions (FAQ's)
