When you are on x and want to do it on y, you have to write as hostname y, not x. Also using single backticks like ` is not ok - those have a complete different effect than using single quotes ' or double quotes ".

Hello all,
I have a relatively simple script I wrote to generate a count of errors broken down. What I would like to do is execute this script from another server so that I don't actually have to log in to the server to run the check.
The script on what we'll call "Server A" is:

the ssh calling convention:
ssh <server>
If I put commands in the section, ssh will execute them immediately after logging in and return to local shell. I want to stay in the remote shell after executing these commands. How can I achieve this?
Thanks for all. (1 Reply)

ssh-keyscan
SSH-KEYSCAN(1) BSD General Commands Manual SSH-KEYSCAN(1)NAME
ssh-keyscan -- gather ssh public keys
SYNOPSIS
ssh-keyscan [-v46] [-p port] [-T timeout] [-t type] [-f file] [host | addrlist namelist] [...]
DESCRIPTION
ssh-keyscan is a utility for gathering the public ssh host keys of a number of hosts. It was designed to aid in building and verifying
ssh_known_hosts files. ssh-keyscan provides a minimal interface suitable for use by shell and perl scripts.
ssh-keyscan uses non-blocking socket I/O to contact as many hosts as possible in parallel, so it is very efficient. The keys from a domain
of 1,000 hosts can be collected in tens of seconds, even when some of those hosts are down or do not run ssh. For scanning, one does not
need login access to the machines that are being scanned, nor does the scanning process involve any encryption.
The options are as follows:
-p port
Port to connect to on the remote host.
-T timeout
Set the timeout for connection attempts. If timeout seconds have elapsed since a connection was initiated to a host or since the
last time anything was read from that host, then the connection is closed and the host in question considered unavailable. Default
is 5 seconds.
-t type
Specifies the type of the key to fetch from the scanned hosts. The possible values are ``rsa1'' for protocol version 1 and ``rsa''
or ``dsa'' for protocol version 2. Multiple values may be specified by separating them with commas. The default is ``rsa1''.
-f filename
Read hosts or addrlist namelist pairs from this file, one per line. If - is supplied instead of a filename, ssh-keyscan will read
hosts or addrlist namelist pairs from the standard input.
-v Verbose mode. Causes ssh-keyscan to print debugging messages about its progress.
-4 Forces ssh-keyscan to use IPv4 addresses only.
-6 Forces ssh-keyscan to use IPv6 addresses only.
SECURITY
If a ssh_known_hosts file is constructed using ssh-keyscan without verifying the keys, users will be vulnerable to attacks. On the other
hand, if the security model allows such a risk, ssh-keyscan can help in the detection of tampered keyfiles or man in the middle attacks which
have begun after the ssh_known_hosts file was created.
EXAMPLES
Print the rsa1 host key for machine hostname:
$ ssh-keyscan hostname
Find all hosts from the file ssh_hosts which have new or different keys from those in the sorted file ssh_known_hosts:
$ ssh-keyscan -t rsa,dsa -f ssh_hosts |
sort -u - ssh_known_hosts | diff ssh_known_hosts -
FILES
Input format:
1.2.3.4,1.2.4.4 name.my.domain,name,n.my.domain,n,1.2.3.4,1.2.4.4
Output format for rsa1 keys:
host-or-namelist bits exponent modulus
Output format for rsa and dsa keys:
host-or-namelist keytype base64-encoded-key
Where keytype is either ``ssh-rsa'' or ``ssh-dsa''.
/etc/ssh/ssh_known_hosts
BUGS
It generates "Connection closed by remote host" messages on the consoles of all the machines it scans if the server is older than version
2.9. This is because it opens a connection to the ssh port, reads the public key, and drops the connection as soon as it gets the key.
