For the security of its servers, IRM has adopted the policy that users may connect to its servers only via SSH. When logging in via telnet, rlogin, and ftp the password is transmitted across the Internet unencrypted. SSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. SSH is typically used to login to a remote machine and execute commands, but it also supports tunneling and can transfer files using the associated Secure File Transfer (SFTP) application.
Here are some links to free SSH/SFTP software for your required platform.
