Have you considered reversing the order ?

That will be much easier to setup and more secure since the log generating machine will not be able to connect @ all to desk_pc.
While desk_pc will be able ssh to log machine and execute specific command/script only (as per key setup).

Race condition with PTY

I've been experimenting with pseudo-terminals and found something I don't quite understand. Writing an EOF character to the master end doesn't work quite as I expect. Once I've written any other data, the master pty seems to treat a single ^D as a seperator, i.e. writing "abcabc" would let cat do... (1 Reply)

SSH-COPY-ID(1)						    BSD General Commands Manual 					    SSH-COPY-ID(1)

NAME
ssh-copy-id -- copy public keys to a remote host SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required). The following options are available: -i file Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a private key is specified and a public key is found then the public key will be used. -l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified. -o ssh-option Pass this option directly to ssh(1). This option can be specified multiple times. -p port Connect to the specified port on the remote host instead of the default. -v Pass -v to ssh(1). The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name. EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs. EXAMPLES
To send a specific key to multiple hosts: $ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3 HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with OpenSSH. BSD
