[Wylug-help] fetchmail & remote login

[roger]

I've always had to start fetchmail by hand when i've restarted my file 
server, but this time I got
----------------
Fetchmail could not get mail from roger at roger-beaumont.co.uk@popserver
The attempt to get authorization failed. This probably means your 
password is invalid, but some servers have other failure modes that 
fetchmail cannot distinguish from this because they don't send useful 
error messages on login failure.
----------------
(I hope I don't have to point out that 'popserver' is just a placeholder 
to conceal my actual account details)
Where should I look to set the correct password when I find it from my 
ISP, please?

What is the command to log into my fileserver from a workstation on my 
network?

TIA
