SSH while read line loop without using remote commands [duplicate]

Question

I have a list of IP addresses I need to ssh into, making unique changes to each one. I tried doing

while read -r line; do ssh -n $line; done < file

but I need to manually run commands and checks on each device. The second I login it kicks me out to the next one. Are there any read line or ssh options that can allow me to do this?

That outputs the contents of the file into the terminal of the remote device. — TomNash

Tell read to use a different FD, then you can remove the -n from ssh.

while read -u 3 ...
do
   ...
done 3< file
