If you already know the name of a host, you can use the command hosts to check if it appears in the NRS (Name Registration Scheme) and, if so, what services it supports.
Names for hosts on the JANET network have the form:
uk.ac.name of organisation.name of host
For example
hosts festival
gives the following information:
Standard Name : uk.ac.edinburgh.festival Abbreviated Name : uk.ac.ed.festival Description : EUCS Central Unix Service Services : X29/JANET FTP/JANET MAIL/JANET
The information on Services shows that this host provides FTP/JANET, allowing you to transfer files between your account on your local host and your account on this remote host.
Host names for commercial hosts on the UK PSS (Packet Switch Stream) have the form:
uk.co.name of organisation.name of host
For example:
hosts ixi
gives the following information:
Standard Name : uk.co.ixi-limited Abbreviated Name : uk.co.x Description : IXI limited Services : MAIL/JANET MAIL/PSS JANET MAIL Relay : uk.ac.uknet PSS MAIL Relay : uk.ac.uknet
You can send electronic mail to IXI Ltd.; but their host(s) do not support file transfer.
