Linux Linux script for multiple box login.

Hello! We currently use a SecureCRT .vbs script which automates logging into multiple boxes to run a few commands. However, I'd like to have something run in Linux vs. our emulator. Below is my objective Smilie:

Our current .vbs script will look at an IP list .txt file on our PC, then login to each IP within the .txt, and execute the following:

ssh router1@[IP Address]
su - root     #prompted for PW.
su - secadmin2    #We don't get prompted for secadmin2 password :)
cd .ssh
cp authorized_keys authorized_keys_bkup
cat /app2/.ssh/Vkey >> authorized_keys
cd .ssh
cp Vkey Vkey.orig
cat Vkey >> authorized_keys
rm /app2/.ssh/Vkey

Again, the script must prompt for root password (only once since all root PW's will be the same), and loop commands above for all IP's found on file. Can anyone help with this? I know many coders here can whip something right quick as you have in the past.....your assistance is greatly appreciated!

I forgot to add vba code were currently using on SecureCRT:

# $language = "VBScript"
# $interface = "1.0"
Sub Main
Dim ObjFSO, InitFSO, Wscript
sDir = "D:\Documents and Settings\BIRDBOYEE"
Set ObjFSO = CreateObject("UserAccounts.CommonDialog")
ObjFSO.Filter = "Text Files|*.txt|All Files|*.*"
ObjFSO.FilterIndex = 1
ObjFSO.InitialDir = sDir
InitFSO = ObjFSO.ShowOpen

If InitFSO = False Then 
  Exit Sub
End If
Const ForReading = 1

  Dim fso, file, str
  Set fso = CreateObject("Scripting.FileSystemObject")
  Set file = fso.OpenTextFile(ObjFSO.FileName, ForReading, False)

  crt.Screen.Synchronous = True
   crt.Screen.Send "grep rtr /etc/hosts" & vbCr
   crt.Screen.WaitForString ">"
 Do While file.AtEndOfStream <> True
  str = file.Readline
  crt.Screen.Send "ssh root@" & str & vbCr
  crt.Screen.WaitForString ">"
   crt.Screen.Send "su - root" & vbCr 
  crt.Screen.WaitForString ">"
    crt.Screen.Send "password" & vbCr    '#Manually enter password here.
  crt.Screen.WaitForString ">"
    crt.Screen.Send "su - secadmin2" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "cd .ssh" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "cp authorized_keys authorized_keys_bkup" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "cat /app2/.ssh/Vkey >> authorized_keys" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "exit" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "exit" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "cd .ssh" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "cp Vkey Vkey.orig" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "cat Vkey >> authorized_keys" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "rm /app2/.ssh/Vkey" & vbCr
  crt.Screen.WaitForString ">"
    crt.Screen.Send "exit" & vbCr
 crt.Screen.Synchronous = False
End Sub

The ususal solution is to set up trusted PPK for your host/id and the target host/id's. With password-free login, you can ssh and run what you want. Also 'parallel' has features designed to support multiple parallel sessions with logging as if they were sequential, to kill the latency.
