Thank you

commands are correct but seems like something is wrong on SCP server , tried on 2 different servers

@Haider Malik please enable "secure copy" on asa through command "ssh scopy enable" firstly. Then you also need to configure the SSH host-key on asa through command "ssh key-exchange hostkey xxx".

Then you can try to use "copy disk0:/asdm.bin scp://username@scp-server-ip/path/to/save"

Here is the successful example in my lab asa for your reference.

TestFW(config)# copy disk0:/khost.log scp://fangni@192.168.1.9/Downloads/test/khost.log

Source filename [khost.log]?

Address or name of remote host [192.168.1.9]?

Destination username [fangni]?

Destination filename [Downloads/test/khost.log]?

Password: ***********
!!!
2090 bytes copied in 5.550 secs (418 bytes/sec)

Related SSH configuration from lab ASA as below:

TestFW(config)# show run ssh
no ssh stack ciscossh
ssh scopy enable
ssh stricthostkeycheck
ssh timeout 60
ssh version 2
ssh key-exchange group dh-group14-sha256
ssh key-exchange hostkey eddsa
ssh 192.168.1.0 255.255.255.0 management

If you saw the error saying some host-key related, you can modify the host key on ASA or SCP server side to get it matched to move forward.

Wish above helps.

@MarkNi
Thank you .
Looks like the user on ASA have some permissions issue.

I tried following up with different SCP vendors, but every time, I get (Permission denied) additionally, it's not even asking for the password for SCP user as in your case.

ciscoasa# sh run ssh
ssh scopy enable
ssh stricthostkeycheck
ssh 192.168.1.0 255.255.255.0 inside
ssh timeout 60

ssh key-exchange group dh-group1-sha1

The issue is not with command, the issue is permission issue of the remote SCP Server

what SCP Server is this running on Windows Server

check - some SCP server need ASA IP to add in allow list (check the SCP Documentation)

also check the Logs in Windows Server.

Hi @Haider Malik from your config of ssh, it seems missing "ssh key-exchange hostkey xxx" . Please make sure you have hostkey configured for ssh.

After that, you can enable "debug ssh 255" and "terminal monitor" , then try to copy again to see if you can find any errors from the debug output.

Wish above helps.
