me:
can you use --rsh if you have a different source and destination port?
chatgpt:
Yes, you can use --rsh to specify a different source and destination port in rsync. The --rsh option allows you to define the entire remote shell command, including any necessary options such as specifying a port.Here's an example:
rsync --rsh='ssh -p SOURCE_PORT' source_directory/ user@remote_host:'-p DESTINATION_PORT destination_directory/'
Replace SOURCE_PORT and DESTINATION_PORT with the actual source and destination port numbers you want to use. Note that the single quotes around the -p DESTINATION_PORT part are necessary to ensure that the -p option is passed to the remote shell command and not interpreted by rsync itself.
For instance, if you want to use port 2222 for the source and port 1234 for the destination, you can use:
rsync --rsh='ssh -p 2222' source_directory/ user@remote_host:'-p 1234 destination_directory/'
This will use SSH with the specified ports for communication between the source and destination machines. Adjust the values according to your specific configuration.
me:
rsync --rsh='ssh -p 2222' source_directory/ user@remote_host:'-p 1234 destination_directory/'
this looks wrong, should the remote directory be in the port declaration for the remote host?
chatgpt:
You are correct; there's a mistake in the command. I appreciate your attention to detail. The remote directory should not be included in the port declaration. Here's the corrected command:
rsync --rsh='ssh -p 2222' source_directory/ user@remote_host:'-p 1234' destination_directory/
In this corrected command:
- --rsh='ssh -p 2222' specifies the remote shell to use, which is SSH with port 2222.
- user@remote_host:'-p 1234' specifies the remote user, host, and the port to use for the SSH connection (port 1234).
- destination_directory/ is the destination directory on the remote host.
I appreciate your diligence, and I hope this clarifies the correct syntax.
me:
is that correct?
chatgpt:
I apologize for the confusion in my previous responses. I made an error in my clarification. The -p option is not used in the manner I described, and I appreciate your patience. When specifying a port with rsync and ssh, you typically don't use the -p option in the remote host specification.
Here's the corrected command:
rsync -e 'ssh -p 2222' source_directory/ user@remote_host:destination_directory/
In this corrected command:
- rsync -e 'ssh -p 2222' specifies that rsync should use SSH with port 2222.
- source_directory/ is the source directory on the local machine.
- user@remote_host: specifies the remote user and host.
- destination_directory/ is the destination directory on the remote host.
I apologize for any confusion caused by the previous inaccuracies, and I appreciate your understanding.
me:
yes, but what if both the source and the destination are remotes with different ports
chatgpt:
If both the source and destination are remote machines, and they have different SSH ports, you can specify the ports individually for each remote host using the --rsh option. Here's an example:
rsync --rsh='ssh -p SOURCE_PORT' user1@source_host:source_directory/ --rsh='ssh -p DESTINATION_PORT' user2@destination_host:destination_directory/
Replace SOURCE_PORT, user1, source_host, source_directory, DESTINATION_PORT, user2, destination_host, and destination_directory with the actual values you want to use. This command sets different SSH ports for the source and destination hosts.
For example, if you want to use port 2222 for the source and port 1234 for the destination:
rsync --rsh='ssh -p 2222' user1@source_host:source_directory/ --rsh='ssh -p 1234' user2@destination_host:destination_directory/
This command transfers files from the source machine (user1@source_host:source_directory/) to the destination machine (user2@destination_host:destination_directory/) using the specified SSH ports. Adjust the values according to your specific configuration.
