I use the cat command to concatenate text files, but one of the rows I was expecting doesn't display in the output file. Is there a verbose mode\logging mechanism for the cat command to help me investigate where the lines I was expecting are going??

There is a file on a remote host that I want to read across an ssh tunnel. NOT copy... scp won't work here. And this file requires elevated permissions to read.
'ssh -t remotehost sudo cat /path/to/file' will prompt me for my sudo password and read out the file. But I'm coming up blank for a... (4 Replies)

When I cat this file content to a variable inside a shell script and echo that shell script, it does not show up as separate lines. I need echo output similar to cat.

Hi Guys,
So what I am trying to do is :
Host A should do a SSH to Host B to F. Login to the remote host and gather the output of uptime and write to to a file in HostA.
So by the end of the script, HostA should contain a file that contains the uptime output of Host B,C,D,E,F.
Right now... (1 Reply)
Hi everyone, after about 2 days of scratching my head on this one, I'm finally ready to punt this and ask for some actual help. Here's the situation. We have 1 server, that runs multiple VM's.

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.
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_ed25519_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_ed25519_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.
