when you say you cannot use ftp telnet etc are you trying to put in hostnames
and have them connect
IE [root@darkstar] ping shell.somewhere.com
reply from. x.x.x.x .......ad nauseum
?
if so then try pinging an ip address
IE [root@darkstar] ping 207.46.131.13 (Microsoft's web server :) may not be
up knowing them! : )))
try a known good ip address
if you can ping an ip address but not a hostname then the problem lies in the
DNS servers are not set up correctly,,,what you need to do in taht case is edit
the /etc/resolv/conf and add the following entrys
domain yourdomain.com
nameserver x.x.x.x
nameserver x.x.x.x
etc
finally do a kill -HUP on the inetd to effect the changes,,(I think)
hope this helps! :)

Nope, the dial up connection is through the win98 box and will remain so
for the foreseeable future, that being till the FreeBSD box is up and
running then that will go and get all my mail/news etc., and then my
win98 box will use its current software (Turnpike) to get mail & news of
the FreeBSD box.
So in my living room for me and friends I will have win98 box, in my
spare bedroom I will have Linux and FreeBSD boxes.

Goto ftp://metalab.unc.edu/pub/Linux/docs/HOWTO There is probably a mail,
sendmail and pop howto there which will explain how to do what you want to do.
Breifly, sendmail handles sending and recieving mail. If you want to receive
mail from the internet, then you are going to have to leave port 25 open. The
latest version of sendmail (8.9.1, I believe) has no known security problems, so
you should be relatively safe. POP/IMAP are protocols that allow clients to get
their email from the server. They are not really involved in sending or
receiving mail. The daemons for both of these services usually come
preinstalled, and all you have to do is uncomment one line from /etc/inetd.conf
and restart inetd (kill -HUP `pidof inetd` or /etc/rc.d/init.d/inet restart
(assuming you use redhat)). POP3 is probably the more popular of the 2
protocols.

A good place to look for instructions is Sunsite @
ftp://sunsite.unc.edu/pub/Linux/docs/HOWTO/
There is a lot of How-To's of many different subjects encluding mail .
As far as ports go: 25 is SMTP, 110 POP3, IMAP 143 . I would get the mail setup
and running first because IMAP uses that to work. What IMAP does is holds the
mail on the server for each client where as POP3 holds the mail for the client
but once the client gets the mail it's gone. On IMAP the mail client connects to
the IMAP daemon and opens the mail database for that user. The mail client uses
the mail server as the mail source.., the mail isn't downloaded to the client. I
have it setup over here so that my mail is always available no matter what
computer I use.

Thanks very much. I've been screwing around with this for just a day so
far. BTW, anyone try the RedHat ftp server with a cable modem? Downloaded
a 53MB postscript FAQ in under 90 seconds. Got up to over 950KB a second.
Fastest I've seen that thing move. Kick-ass server with a T3 connection I
gotta assume. Anyway, thanks again.

You guessed right, They drastically changed and improved firewalling and
masqing code in 2.1.xxx. Basically, ipchains has replaced ipfwadm.

Put the cursor over the character you want to replace and type 'r'
followed by the character.

Oracle 8.0.5 for linux might require libtcl 8.0.2 for the intelligent

and install 8.0.2 or can I run both somehow. Will it affect other

Redhat 5.2 Server vs Workstation: Anyone using the server out there???
========================================================================================
This is a pretty basic quesiton and a problem I've had with many
installs in the past. (i.e. Redhat 3.0.3 thru 5.1)
Question I'm looking to have answered:
"What server software is installed when you use this option?"
In the past I've had to manually install the:
FTP server
POP3 mail server
(In fact the pop3 server was not even on the CDs and I even got the
powertools disk set)
and some other programs. (I forget the exact names)
Anyhow, can anyone tell me what installs by default and what else one
can choose from?
Thanks,
Ken

The hosts.{allow|deny} files are only used by tcpd(8), and not by lpd(8). lpd
looks in /etc/hosts.equiv and /etc/hosts.lpd, so you need to setup one of
those two files. See the lpd(8) man page for details.

I've always used the network configuration module of the control-panel

devicename entity address
So, for example, I have 2 Ethernet cards, eth0 and eth1. My default route is

eth0 net <address> netmask <netmask>
If this doesn't help, post some specifics as to your configuration, and maybe
we can help further.
