hosts.deny/hosts.allow

Hello,

I just got NFS working on my debian system.  I installed the tools for
NFS, and it somehow disabled my ability to telnet between computers on my
lan.  I noticed in hosts.deny, an entry saying "ALL: PARANOID."  I
commented this out, but that doesn't appear to be the holdup, because I
still couldn't telnet.  I put "ALL: 192.168.1. " in my hosts.allow file,
but that doesn't work either.

Strangely, I can ftp to all machines.  I also was encouraged to use ssh,
and I will, but I'll need to learn how to configure that too.  Any help
with this would be appreciated.  Thank you.

Bob Gamble

Check to make sure that there is no firewall in place which is blocking your
requests.  You may also want to change your hosts.allow file to look something
like this:

ALL: 192.168.1.0/255.255.255.0

Although I am not sure why you can ftp and not telnet.  You may want to check
to make sure that your telnet daemon is still listening for incoming requests.

See ya

That is the same thing.  To test it from localhost it might help to use:

ALL: LOCAL 192.168.1.

Check the logs after attempting to connect.

1. tcpd (hosts.deny/hosts.allow)

Hi,

I've seen on some hosts, if they've blocked off a certain host from telnet
access (for example) then they print out a message to the terminal before
closing the connection.

I've been trying to do this using hosts.deny, because it allows you to
execute commands, but I can't get it to work. I have this:

ALL: ALL: /bin/cat /etc/deny-mesg > `/usr/bin/tty`

but that doesn't work. :\

Has anyone got any ideas of how it is done? (or whether a different
program/method is used?)

TIA,

Joe.
