Remote Access & Lateral Movement

Linux OS

SSH

# Normal connection
ssh mara@192.168.0.191
# With Private Key
chmod 700 key.txt
ssh -i key.txt stinky@192.168.142.219

# If you have a shell issue at login
ssh -t  margo@192.168.103.110 /bin/sh

# XForward
ssh -X fox@$RHOST

When you see the following error - Too many authentication failures in ssh,

Try the following tricks.

# Clear Authentication caches 
ssh-add -D
# Then ssh 
ssh -i key.txt stinky@192.168.142.219 

# Or add the o option -o identitiesOnly=true 
ssh -i key.txt stinky@192.168.142.219 -o identitiesOnly=true
