I want to create a script that will set up key pairs from "thishost" to "remotehosts". I have a validate script in ~/<dir> that I need to prefix the generated key in the authorized_keys file, and I'm having to manually do this everytime.
Here are my attemps, perhaps you could perfect them for me.
- not sure if I can ssh to multiple users@hostname by piping?
I then realised I could save a lot of work using text-processing (especially if we were setting up a lot of keypairs), but I know you will criticise me for being over-complex, and possibly UUOC. :-)
However, this puts the text on a new line, which I don't want. I just want it to prefix the generated text. Would awk or sed be easier for this, and how would I do it over ssh, thus cutting out manual text entry on the remote boxes?
I need to insert a file called temp_impact (which has about 15 lines in it) to a file called 11.23cfg starting at line 33. I searched the forums and found the
sed '34i\
test' 11.23cfg > newfile
That will enter word test at the appropriate line, but i need the entire file dumped there. Any... (4 Replies)

I have a text file with one line having few words separated by space and I need to insert another word on "n"th column/field so that previous word should shift right (to n+1st column). how can I do that?

Please advise, thanks!

ssh-keysign
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.
