Error "standard in must be a tty" when doing ssh username@server 'sudo command'
When
ssh username@server 'sudo command'gives “standard in must be a tty”. First solution: Edit your /etc/sudoers file, by using visudo command:
visudocomment out the line “Defaults requiretty”.
A most secure way should be to add:</p>
Defaults:[username] !requirettySecond solution: forcing allocation of a pseudo-tty.by using -t option
ssh -t username@server 'sudo command'Additional information
This behaviour is not the default. Only Redhat distributions of sudo that had requiretty in its default sudoers. It will be fixed in newer releases
