I have written a bash script that goes to each machine and runs set of command. I am using the user iis that has sudo privlidges on that machine. However, when i run the sudo yum command i get sudo: sorry, you must have a tty to run sudo.
Not sure what is wrong ? I am using the -t command to force but it would still not work
bash script
#!/bin/bash
INPUT=ccidetails.csv
OLDIFS=$IFS
IFS=,
[ ! -f $INPUT ] && { echo "$INPUT file not found"; exit 99; }
while read privateip password
do
echo $privateip
scp /home/Data/Test.c iis#$privateip:/tmp
sshpass -p$password </dev/null ssh -t -o "StrictHostKeyChecking no" iis#$privateip "
hostname
cd /tmp
gcc Test.c -o TEST
./TEST
sudo yum -y update glibc
gcc Test.c -o TEST
./TEST
exit
" >> output.txt
done < $INPUT
IFS=$OLDIFS
Error:
sudo: sorry, you must have a tty to run sudo

Answer 1

On remote host comment the line below on /etc/sudoers:
grep tty /etc/sudoers
#Defaults requiretty
That will allow you to continue. Make sure you understand the consequences of doing so:
man sudoers | grep -i requiretty -A 5
requiretty If set, sudo will only run when the user is logged in
to a real tty. When this flag is set, sudo can only be
run from a login session and not via other means such
as cron(8) or cgi-bin scripts. This flag is off by
default.
If you don't want disable requiretty globally you can disable it for a specific user:
example:
Defaults requiretty
Defaults:your_username_goes_here !requiretty

While this isn't a question for SO, you're almost there ... what you need to change is the number of -t above ... try this:
sshpass -p$password </dev/null ssh -ttt -o "StrictHostKeyChecking no" iis#$privateip "
