Shell implements a springboard machine

• Zbuz add users, and bulk distribute SSH public key scripts:

#!/bin/bash. /etc/init.d/functionsfunction add_user () {         jumper= "$"         useradd ${jumper}         echo 123456 | passwd --stdin ${jumper} >/dev/ null 2>&1                 if [  ' grep -o  $jumper  /etc/passwd | wc -l '  -gt 1  ]                         then                         action  "Add user  ${jumper} success " /bin/true                 else                         action  "Add user ${jumper} success failure"  /bin/false                         exit 0                 fi        su  ${jumper} -c  "ssh-keygen -t dsa -p "  -f ~/.ssh/id_dsa > /dev/null 2>&1 "                 if [ $? -eq 0 ]                         then        &nbSp;                action   "Create ssh pub key success"  /bin/true                 else                         action   "Create ssh pub key failure"  /bin/false                 fi}add_user $*for n in 7  8    do        /usr/bin/expect /server/ Scripts/fenfa_key.exp /home/${jumper}/.ssh/id_dsa.pub ${jumper} 11.0.0.${n} >/dev/null  2>&1        IF [ $? -EQ 0 ]           then          action  "Fenfa ssh  pub key to 11.0.0.${n} success " /bin/true         else          action  "fenfa ssh  Pub key to 11.0.0.${n} failure " /bin/false         fidone

• Expect for no password verification

#!/usr/bin/expectif {$ARGC! = 3} {puts "usage:expect $argv 0 Sshkey User host" exit} #define VarSet Sshkey  [lindex $argv 0]set User [lindex $argv 1]set host [lindex $argv 2]set password "123456" Spawn ssh-copy-id-i $sshkey [email Protected] $hostexpect {"yes/no" {send "yes\r"; exp_continue} "*password" {send "$password \ r"}}expect E Of

• Boot script call Springboard machine script
