Change password

[giada]

Hi,
I've the same user on 100 hosts. I must change its password on every host. I'd like to do this with a script. I can use the remsh command. For example:
for host in $(cat host.txt)
do
remsh $host -n ..........

where hosts.txt is a file with the hosts' name
Any idea?
Thanks
Giada

Hi,

your script works, if the rsh has been configured on all the 100 hosts, else the passwd will not change on which rsh has not been configured.

NIS can be used here.

Hi

If you have 100 hosts, why not you implement NIS. You can centralize user passwd and group in one server.

The rsh has been configured on all hosts. I couldn't use NIS for organizational and managerial problems.
Thanks

Hi,

for host in 'cat host.txt'
do
rsh $host
echo " password for the user in host $host"
passwd
done

Giada,
please have a look at my previous reply re. updating multiple hosts automatically.

I though you may want to set passwords automatically on each host, rather than from the command line.

Can you please clarify: commandline or multiple change?

Peter,
I want to change passwords (the password will be the same for all hosts) from one host automatically on all the other hosts.

Giada,
thanks for the clarification.
NIS would be the ideal solution, but as you said is not available.
So the process would be:
automatic
copy the password file from the host
modify it with sed
copy it back
or
manual
remsh $host -n vipw

You can change the password on the remote hosts by using SAM's usermod command which is found in /usr/sam/lbin/usermod.sam

/usr/sam/lbin/usermod.sam -p wehbTH45!i login_name

The -p option allows you to place an encrypted password on the usermod.sam command line. To get the encrypted password, change the password on one of the machines, then copy the encrypted password for use with usermod.sam
