If sudo needs a password, then it needs a tty, sure.
But sudo also complains, when it doesn't need a password, because NOPASSWD is in effect. Just had that situation a few days ago. And the reason for this is the requiretty setting in the sudoers file afaik.
ssh user@host sudo.. -> complaint,
ssh -t user@host sudo... -> success without asking for a password,
removing requiretty and ssh user@host sudo.. -> success

csp_install
csp_helper(1) USER COMMANDS csp_helper(1)
NAME
csp_helper - A collection of caspar helper scripts
SYNOPSIS
csp_install dir (directory) file (file)
csp_mkdircp dir (directory) file (file)
csp_scp_keep_mode h ([user@]host) dir (directory) file (file)
csp_sucp h ([user@]host) dir (directory) file (file)
DESCRIPTION
The scripts csp_install, csp_mkdircp, csp_scp_keep_mode and csp_sucp are helpers for caspar(7). These scripts typically are not invoked
directly, but via a Makefile which uses caspar. See the notes on csp_PUSH in caspar(7) for information on how to link csp_install,
csp_scp_keep_mode and csp_sucp to caspar.
install DESCRIPTION
csp_install creates the required directory (if needed) and installs the file, preserving timestamps. It uses install(1).
install EXAMPLES
csp_INSTALL_OPTIONS='--owner=www-data --group=www-data'
csp_INSTALL_MODE=ugo=r
csp_install /srv/www index.html
csp_INSTALL_MODE=u=rwx,go= csp_install /usr/local/sbin mkpasswd
install ENVIRONMENT
csp_install honors csp_INSTALL_OPTIONS and csp_INSTALL_MODE (default is u=rw,go=r).
mkdircp DESCRIPTION
csp_mkdircp calls mkdir(1) and cp(1).
scp_keep_mode DESCRIPTION
csp_scp_keep_mode uses ssh to copy a file to a remote host, keeping its file permission mode. The trick used is a combination of mktemp(1)
and mv(1). Useful if you'd like to be sure a file gets installed e.g. group writable, without fiddling with permission bits on the remote
host.
scp_keep_mode EXAMPLE
chmod g+w rc
csp_scp_keep_mode root@gandalf /etc/uruk rc
scp_keep_mode ENVIRONMENT
csp_scp_keep_mode honors csp_SSH ("ssh" by default).
sucp DESCRIPTION
csp_sucp calls cat(1) from within sudo(1) from within ssh(1). This allows one to copy files to accounts on hosts one can only reach by call-
ing sudo on the ssh-reachable remote host.
Typically, one wants to install a root-owned file, but one does not want to allow access to the root-account directly from ssh. Typically
sudo is used as an extra line of defense.
sucp EXAMPLES
Some examples:
csp_sucp rms@bilbo /etc fstab
csp_sucp monty-python commit/ trailer.txt
sucp BUGS
If NOPASSWD is not set in the sudoers(5) file, and one's timestamp is expired, csp_sucp will forward the sudo password prompt. The given
password will be echoed on the console!
