I am trying to think of a way to create user ids on multiple Linux systems in one fell swoop without logging onto each system indivually. Is there a way to do this with ssh commands? I don't want to use NIS/LDAP solution just a simple shell script utilitarian methodoloy would suffice. Also, I am... (1 Reply)
I've had Linux when I was young, on one of our first computers and learned it pretty quickly... However, I've been working on Windows for about 7 years now and just made the switch back to Linux, Mandrake 9.1. So I have some problem with creating new user accounts. I could create one, but once I... (3 Replies)

I have a directory full of zip files.
How would I write a bash script to enumerate all the zip files, remove the ".zip" from the file name, create a directory by that name and unzip each zip file into its corresponding directory?
Thanks!

Hi,
Can someone help me with creating a bash shell script.
I need to create a script that gets a positive number n as an argument.
The script must create n directories in the current directory with names like map_1, map_2 etcetera. Each directory must be contained within its predecessor. So... (7 Replies)
Hi
I need to create a user who can have access on only one folder.
for example I created a user "test" . he should have access only on folder
/testfolder.
The problem is that the user will mostly use FileZilla to ftp his files in the testfolder.
In the fileZilla , i want him to be... (21 Replies)
I have a script on about 15 hosts that I need to run for each host whenever I want (not crontab). Problem is, this script takes 5-10 mins to run for each host. Is there a way I can run the script in parallel for all the hosts instead of 1 at a time? Also, I'm remotely running the script on the... (3 Replies)
I have a script to detect if a host is pingable or not. The problem is that I would like it to put the nonpingable hosts in one file and the pingable hosts in another. I have come up with this so far:

Hi everyone!
Some time ago, I had to check connectivity with a big list of hosts, using different formats (protocol://server:port/path/, server:port, ....).
I developed a script that checks the connectivity using different commands (ping, telnet, nc, curl).
It worked for me so I'm sharing it... (9 Replies)

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. Note that ssh-keysign is not set-uid by default on Mac OS X.
/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.
