Operating Systems Linux Red Hat Difference in file sizes being copied by scp. HELP! Post 302653381 by NotALinuxGirl on Friday 8th of June 2012 05:42:18 PM

Sorry, I'm not sure I understand what you mean by
"I take it there are two processes here -- a local one which copies the files over, and another on the server, which runs unseen, and extracts the .gz files into logs"

My crontab runs:
20 3 * * 1,2,3,4,5,6 /data05/oradata/dpdump/cpFromDB.sh > /data05/oradata/dpdump/cpFromDB.log 2>&1

And here is my script:

cpFromDB.sh

scp -C root@xxx.xx.xxx.3:/data05/oradata/dpdump/*.gz /data05/oradata/dpdump/.
ssh -l root xxx.xx.xxx.3 rm -f /data05/oradata/dpdump/*.gz /data05/oradata/dpdump/db*.log

So, scp is the one that "a local one which copies the files over", but where is the other one that "on the server, which runs unseen, and extracts the .gz files into logs"? Is it ssh line?

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME
ssh-keysign -- ssh helper program for host-based authentication SYNOPSIS
ssh-keysign DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with SSH protocol version 2. ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign to ``yes''. ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen- tication. FILES
/etc/ssh/ssh_config Controls whether ssh-keysign is enabled. /etc/ssh/ssh_host_dsa_key /etc/ssh/ssh_host_ecdsa_key /etc/ssh/ssh_host_rsa_key These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read- able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host- based authentication is used. /etc/ssh/ssh_host_dsa_key-cert.pub /etc/ssh/ssh_host_ecdsa_key-cert.pub /etc/ssh/ssh_host_rsa_key-cert.pub If these files exist they are assumed to contain public certificate information corresponding with the private keys above. SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8) HISTORY
ssh-keysign first appeared in OpenBSD 3.2. AUTHORS
