Network Services and the Server Machines
This document lists core network services such as email and web services and provides the names of servers that provide those services.
Email Services
- Mail Transfer Agent (MTA) : smtp.physics.utoronto.ca
- This is what most people are thinking of when they refer to the mail server. The MTA delivers email to remote mail servers and drops mail off on the local system with some possible assistance from a local mail delivery agent (MDA) such as procmail.
- IMAP Remote Mail Access : imap.physics.utoronto.ca
- IMAP is one of the two common protocols (the other is POP3) for reading email on a remote server. For most cases it is the recommended mechanism for remote mail access in a modern email environment.
- POP3 Remote Mail Access : pop.physics.utoronto.ca
- POP3 is an older, but still popular access protocol for fetching email stored on a remote server. It was designed for email which is downloaded to the local client and removed from the server.
For assistance in configuring a mail user agent (MUA) — typically a mail reading and composing program such as Netscape Messenger, Pine, MS Outlook or Qualcomm Eudora, see Email Client Configuration.
File Transfer Services
- FTP Server : ftp.physics.utoronto.ca
This server resides on the helios server cluster and provides authenticated user access to files on the central storage server.
Because the FTP protocol uses plain-text, unencrypted authentication, it is considered deprecated and will eventually be retired. Please consider using other file transfer methods.
- Scp and Sftp
- Ssh services are widely available within the department and are considered the correct and supported method for performing file transfers between unshared filesystems.
