Resource Load Tips and Tricks

  • Redirect dynamic page to static page if resource issues arise from high traffic to a single Webpage
  • sar -q
  • top -c
  • netstat -antp
  • lsof -itcp
  • lsof -i :80

    When you see the PID that is connecting to a remote port 80 rather than accepting a connection to local port 80, use lsof -p on that pid number to find the working directory of it.


Security


Check if we support insecure SSLv2:
  • openssl s_client -connect 127.0.0.1:443 -ssl2
 
 
 

Check for outbound connections to remote port 80

  • netstat -atnp |awk '$5 ~ /80/ {print $0}'
 
The script above this line uses regex to search for "80" within the 5th column of the `netstat -atnp` command output
 
  • netstat -atnp |awk '$5 ~ /80$/ {print $0}'
Will do the same, making sure the string search looks for "80" at the end of a string


  • netstat -atnp |awk '$5 ~ /:80$/ {print $0}'
Will do the same, making sure the string search looks for "80" at the end of a string AND is preceded by a colon.
