Requirements to be Met

  • Must have Linux ISO downloaded (In this case, it is CentOS 7 KDE live ISO.)
  • Must have internet access on Linux VM
  • The switch is reachable from VM
  • Switch Sysadmin role user
  • Must not have “system-cli disable” configured

Steps to Run Script from Live Linux ISO

  1. Boot to the ISO from VMware (or another hypervisor)
Link for CentOS 7 KDE live ISO download:
 
Created VM settings with mounted ISO:
Boot into the CentOS disk:

 
  1. Right click to open Konsole.

 
  1. Run yum, install, expect, and unzip.
sudo yum install expect unzip -y
 
 
 
  1. Save file to Linux system (can transfer directly to host or download for DDL using Firefox).
scp <user>@<hostip>:</filelocation/filename> <filename>
 
 
  1. Unzip the file and run chmod to make the file executable.

unzip cert_upgrade_script-3.zip
chmod 777 cert_upgrade_script/*

 
  1. Run file to each switch IP or with host file per readme to confirm vulnerable and applied.

cd cert_upgrade_script
./cert.sh -u admin -p admin -h <IP> -c
./cert.sh -u admin -p admin -h <IP>
./cert.sh -u admin -p admin -h <IP> -c


 

  1. After executing the script, check KB article 184027: Dell Networking OS10 Certificate Expiration and Solution. for the next steps.
ALERT: Flap the VLTi or reload switch based upon KB steps for cert to take effect.
 

Command Summary

Command Explanation
sudo yum install expect unzip -y Install needed packages
cd Desktop Move the desktop directory
scp <user>@<hostip>:</filelocation/filename> <filename> Download the script to the Desktop

chmod 777 cert_upgrade_script/* chmod to allow the .sh and folder to be read/write/execute
cd cert_upgrade_script Change to the cert directory
./cert.sh -u admin -p admin -h <IP> -c check the switch is vulnerable.
./cert.sh -u admin -p admin -h <IP> Run script to change cert
./cert.sh -u admin -p admin -h <IP> -c Check to see if switch was updated
 

Items to Take Note

  • The script does version checks for if running at a version earlier than 10.4.3.x.
    • If running earlier than this version, it creates the message “running a version less than 10.4.3.x, please upgrade to newer version”
  • The script does version checks for if funning at a version later than 10.5.1.0. (in script version v4).
    • The system is not vulnerable if other switches in the cluster are also running 10.5.1.0 or later.
    • Newer firmware may have affected cert however, it is not in use, and as such, can be ignored or upgraded without concern.
  • Ensure to use ‘ (single quotes) if special characters are in username or password on Linux.
  • If existing Linux OS, ensure version is 5.45 or later.
