HOWTO Restart LPD

HOWTO Restart LPD

[Peter]

Hi,
When cups has been activated for printing, then on rebooting lpd is not 
started anymore.

How can I restart lpd from the command line instead of using printtool or 
printconf-tui? I can't find anything in man lpd.

Thanks & regards

If you connect to a remote server, by any means, there is no way to hide 
from that server the apparent IP address you are connecting from. That is, 
the remote server will either know the IP address of the host you are 
connecting from, or the host you are connecting through (in the sense of, 
say, a NAT'ing firewall or perhaps a proxy server of some sort). It has to 
know that or it cannot maintain the connection.

Technically, there is no way for the remote server to know your actual 
hostname, in the sense of whatever your host happens to have in the file 
/etc/hostname . But if it can do a reverse-lookup of your IP address, it 
can, and usually will, know a FQN associated with your host.

In principle, if you have root privileges on the remote server, you can 
modify the applications who, finger, and w, so they do not display the FQN 
or IP-address data. How to edit and recompile these apps is not really a 
beginner question, so I won't go into detail here (and anyway, I don't know 
the source for any of these apps well enough to answer at that level 
without doing some work). But there is nothing you can do on the host you 
are connecting *from* to accomplish what you want.

Re: hiding my hostname (2)

[Jesse Armand]

well.. I think there is a way,
why ?
because i've just seen it.
when i'm logging in to a server, 
i saw a client that hiding his hostname,
and it's not about the server not knowing my ip
address, it's about hiding my ip address from viewing
by other users. 
I know a server must know an ip address of the client
that connects to it.

when i use 'w' or 'who' command
the hostname table shows empty content

USER    TTY   FROM    LOGIN@    IDLE    WHAT
woho    p1     -      10:09AM    -      - (pine) 

can u explain that ?

btw by using .nofinger i can hide myself from
fingering,
that's one way,

so anybody knows how to hide my hostname from 'who'
and 'w'

That is caused by someone being logged in through the console.

There is no hostname to hide. His login is LOCAL to the host on which you 
are running w, not remote from a different host. That's what "through the 
console" means.

Since he is logged in from the console there is no host information
displayed.

   From what I've seen, that dash in the "From" column usually means a local
(to that machine) login...

Re: hiding my hostname

Sorry you can't do it.  The machine you are connecting to will ALWAYS 
know the machines ip address of the machine you are connecting from.

Re: HOWTO Restart LPD

[J S]

Under RH 9.0 and most recent versions of RedHat as well as Mandrake,
just use the script in /etc/init.d


For example...

/etc/init.d/lpd restart


The other scripts in /etc/init.d are helpful for other services.  Most
of the scripts take as an argument on of the following: start, stop,
restart, and status.  These are very helpful at times.  I'm sure there
are some other options as well, but I've never used them.

Thanks!

That's the script used on booting where I get: Starting lpd:  No Printers 
Defined

Doing "/etc/init.d/lpd start" from the command line I therefore get the same: 
No Printers Defined.
Ergo before starting lpd a printer has to be defined first.

Can that be done from the command line?

Re: HOWTO Restart LPD

[Bryan Whitehead]

If your using CUPS then the service is "cups".

"service cups restart" will restart it. or "service cups start" will 
just start it.

for cups to start up automagically run this command:
chkconfig --add cups

/sbin/service lpd or cups start/stop
