Hi, we found the cause of the problem.
We used puppet to distribute everything and then SMSG to restart sshd to use
the new config file.
But sshd was not restarted with the normal environment setup since it was via
udev-rule triggered via a SMSG.
When we used expect together with Terminal Server to login into all servers and
restart sshd by root, and then it worked fine.
Solution looks like this:
First of all you need to have expect installed on the terminal server. (If not:
yum install expect [as root])
Then you need a script, an expect script as following: (note: Execute the
script as your own user!)
#!/usr/bin/expect
#Usage script.expect <host> <ssh user> <ssh password>
set timeout 60
spawn /usr/bin/iucvconn [lindex $argv 0] hvc2
expect "login:" { send "$argv 1\r" }
expect "Password:" { send "$argv 2\r" }
expect "$ " { send "sudo su\r" }
expect ": " { send "$argv 2\r" }
expect "# " { send "A COMMAND\r" }
expect "# " { send "exit\r" }
expect "$ " { send "logout\r" }
#interact
The timeout is needed! Since if your terminal connection fails for some reason
it needs to be stopped. The timeout does this for you.
You can send more commands, but don't forget to send a "\r" after each one.
You can uncomment the interact, but leave it like this if you want to execute
the script on multiple servers.
For example you can query zVM and put all servers in a txt file and execute it
for all servers.
#!/bin/sh
while read server
do
echo "$server"
./script.expect "$server" "userx" "mypassword"
done < servers.txt

Hi.
Anyone having problem with ctrl-c not working after adding support for
hw-crypto ?
Turning off hw-crypto support makes it work again.
Ctrl-c also works if logged in via iucvtty (Terminal Server)
