FTP files

The primary purpose of the FTP server is to house those files we wish to make publicly available either to LDEO users with accounts or to 'anonymous' external users without local accounts. The ftp server also accepts incoming material (usually too large for an email attachment) from the outside from both users with and without LDEO accounts.

Pickup Folder: pub

(Using your lamont username and password)
