I have a Perl script that I run from cron. It's not pretty (I know
almost nothing about Perl); it just works.

It's something like this:

#!/usr/bin/perl -w
use strict;

my $url = 'http://www.somesite.com/index.html';

# access the url with lynx, redirecting STDOUT to ELFILO
# one can use either -source or -dump; see man lynx
open ELFILO, "lynx -accept_all_cookies -source '$url' |" ;

while (my $line = ) {
do something with $line using regular expressions and print whatever output I 
need
}

If /etc/redhat-release was edited and the redhat-release rpm was
uninstalled, I wouldn't worry about what Red Hat version I'm running. I

I assume you have vim installed.

Turn off syntax highlighting:

You may want to edit your ~/.vimrc file and comment out the section that

In my mail server:

Red Hat Linux release 7.1 (Seawolf)

# rpm -qif /etc/xinetd.d/ipop3
Name: imap Relocations: (not relocateable)
Version : 2000cVendor: Red Hat, Inc.

Summary : Server daemons for IMAP and POP network mail protocols.
Description :
The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access
protocols.  The POP protocol uses a "post office" machine to collect
mail for users and allows users to download their mail to their local
machine for reading. The IMAP protocol allows a user to read mail on a
remote machine without downloading it to their local machine.

Install the imap package if you need a server to support the IMAP or
the POP mail access protocols.

It's somewhat documented.

4.3.  Usenet Signature Convention

   There is a convention in Usenet news of using "-- " as the separator
   line between the body and the signature of a message.  When
   generating a Format=Flowed message containing a Usenet-style
   separator before the signature, the separator line is sent as-is.
   This is a special case; an (optionally quoted) line consisting of
   DASH DASH SP is not considered flowed.



4.5.  Quoting

   In Format=Flowed, the canonical quote indicator (or quote mark) is
   one or more close angle bracket (">") characters.  Lines which start
   with the quote indicator are considered quoted.  The number of ">"
   characters at the start of the line specifies the quote depth.
   Flowed lines which are also quoted may require special handling on
   display and when copied to new messages.

The good news is that your website is working; the bad news is that you may 
have to make further changes. I didn't want to tell you this when we were 
discussing your problem off-list, because it would have added complexity to 
the situation.


Your Linux box gets its IP address (192.168.1.101) from the router via DHCP.


If my crystal ball is not working, stop reading and delete this post.

You don't need DHCP on the Linux box now, because you are behind the 
router. Reconfigure your box with a static ip address. Log into your router 
and check the DHCP tab. You want to assign an IP address that it's outside 
the router's DHCP server range. I'll bet you 2 dollars that 192.168.1.10 works.

The problem with having the Linux box get the IP address from the router is 
that the box, could, at least in theory, get an address other that 
192.168.1.101 in the future, forcing you to change the IP addresses in 
httpd.conf.

The situation, as I understand is this:
You want to serve a web site from a box behind a Linksys Cable/DSL router.
You were serving this web site before, but the box hosting it was directly 
connected to the Internet.
Your web site is omega-fleet.homelinux.org. It resolves to 24.158.191.171
24.158.191.171 is the external IP address that your router reports.
The IP address of the box hosting the web site is 192.168.1.101
If I access omega-fleet.homelinux.org from the Internet, I get your router 
management tool.

My feeling is that the only thing that you have to do is have the router 
forward external http requests to your internal box. I happen to have a 
Linksys BEFSR41. In this router, I would go to the Advanced tab, then to 
the Forwarding tab. In the Forwarding tab, I would enable forwarding of TCP 
on the external port range 80 to 80 (ie only port 80) to IP address 
192.168.1.101.
And disable Remote Management for the router, unless you really, really 
need it.

The length of this thread is 17 messages now, and no one has posted the 
solution to Mr. Nagy's problem. Apparently Mr. Burger and Mr. Hughes 
consider more important to write procmail recipes than helping fellow Red 
Hat users.

There are at least two ways of getting your external IP address:
1. Log into your router and get it from there. You'll have to check the 
router's documentation for the exact commands to do this. Most home-office 
routers hava a web interface.
2. Point your browser to www.ipchicken.com. Your IP address will be 
displayed there.

Let me clarify:
What I did mean is "read the fucking manual" and "search the fucking
web". Maybe in upper case. That's the response Mr. Nagy deserves.

Before anyone flames me for being too harsh on newbies, consider this:
1. Mr. Nagy knows the solution to his problem, he just cannot remember
it. Apparently he's too lazy or stupid to take notes.
2. He is aware that he should search on google and read the docs before
posting, but no, he won't do it. He considers himself beyond that.
3. I assume he knows the exact problem he has (because he already knows
the solution), and yet he will not state it in a clear manner. He just
asks how to find the "IP info", when in fact he needs to find the
external ip address of the router that it's between his workstation and
the internet. At least that's what I understood from his moronic,
selfish posts.

You need to install openssh-server. See Description below

[saul@saul saul]$ rpm -qi openssh
Name: opensshRelocations: (not relocateable)
Version : 3.1p1  Vendor: Red Hat, Inc.
Release : 6  Build Date: Wed 26 Jun 2002 03:56:22 PM EDT
Install date: Sat 29 Jun 2002 04:41:25 PM EDT
Build Host: daffy.perf.redhat.com
Group   : Applications/Internet Source RPM:
openssh-3.1p1-6.src.rpm
Size: 627058   License: BSD
Packager: Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla>
URL : http://www.openssh.com/portable.html
Summary : The OpenSSH implementation of SSH.
Description :
SSH (Secure SHell) is a program for logging into and executing
commands on a remote machine. SSH is intended to replace rlogin and
rsh, and to provide secure encrypted communications between two
untrusted hosts over an insecure network. X11 connections and
arbitrary TCP/IP ports can also be forwarded over the secure channel.

OpenSSH is OpenBSD's version of the last free version of SSH, bringing
it up to date in terms of security and features, as well as removing
all patented algorithms to separate libraries.

This package includes the core files necessary for both the OpenSSH
client and server. To make this package useful, you should also
install openssh-clients, openssh-server, or both.

Can you ping from the Linux box to 192.168.0.3?

Can you do the pings above with iptables shut down?

Minor, but important correction:
find $mydir -ctime 183< finds files changed 183 days ago, no more, 
no less
find $mydir -ctime +183   < finds files changed more than 183 days ago

I apologize. Allow me to point the guy in the right direction:

3. Type "where is linuxconf in redhat 7.3" in the input box (with the

5. Click with your mouse on the following link that will appear as the 
first search result: "Computing.Net - Where is linuxconf in RedHat 7.3"
6. Read

I once was also "a new person trying to learn Linux". However, I wasn't as 
lazy as to not try to find the answer by myself before posting to this list.

Why was my response of no help? I answered his two questions by clearly 
stating that linuxconf has been removed from RH 73 and that I suggest he 
tried webmin, which is easier and more powerful than linuxconf, IMHO.

netstat -ta
Take a look at the State column of the output. If it shows LISTEN, then the 
system is listening at that port.

I have a PII-266Mhz with 160 MB RAM. I run RedHat 7.3 with Gnome. I usually 
have several xterms open, plus Evolution, Opera and the Yahoo Messenger, 
and the speed is not a problem for me. My impression is that you don't need 
more RAM.

Do a "ps -axfu" to see which processes you are running. Maybe you have 
something running in the background that you don't need. Take a look at the 
"top" command, also. Another suggestion is to "purge" Evolution mailboxes, 
as these can get really big. I don't remember the exact command to do that, 
and I'm in Windows now (I have a network adapter, that I use to connect to 
my wife's laptop, which I have not gotten to run under Linux).

You might want to use -iname, instead of -name, to do a case-insensitive
search. This is useful if the user has a Windows background, where they
are not used to file names being case sensitive.

VPN: FreeSWAN or Cipe

2002-04-12 Thread Saul Arias

I have to set up a VPN between two networks at separate physical
locations over DSL connections (static IP), using two RH 72 boxes as
end-points. After some research, I have found that I can use either
FreeSWAN or Cipe.

I do not know which way to go. It looks that FreeSWAN is the "standard",
but looks much more complicated to set up than Cipe.

Any suggestions, comments, recommendations will be appreciated.

Re: How to Change Hostname?

Don't reboot. Reboot is for Windoze and kernel upgrades.

service network restart

dst cache overflow

2001-12-03 Thread Saul Arias

We've had a problem with our web server twice in the last month.
Suddenly the machine stops responding to remote access (http, ssh, ftp,
even ping). In order to solve the problem, we logged on to the console
and rebooted the server. 

/var/log/messages shows a lot of lines like these:
kernel: dst cache overflow

Doing some research on google I found that this problem somewhat relates
to a routing cache table filling up (whatever that means).

Someone suggested issuing a "ip route flush cache" regularly via crond,
to avoid the routing table filling up.

Our system:

RH 7.0, kernel 2.2.19 (we upgraded to this kernel just a week ago, we
were running 2.2.16 when the server stopped responding)

apache-1.3.12-25
Oracle 8.1.7
JRun 3.1

Apache receives around 100,000 requests a day.

Any suggestions will be highly appreciated.

Saul

Re: Samba

2001-11-29 Thread Saul Arias

I had the same problem six months ago.

Have you changed your hostname after the last time you restarted Samba?

I fixed it by modifying the localhost line in /etc/hosts to look like
this:

[saul@server]$ cat /etc/hosts
127.0.0.1   server.etiresinstallers.com server localhost

Hope this helps.

Re: securing ftp

2001-04-26 Thread Saul Arias Laso

I run ProFTPD, from www.proftpd.org
Works almost right out of the box.
There is an option in the proftpd.conf file, called DefaultRoot, that does 
exactly what you need.

Openssl dependencies

2001-04-20 Thread Saul Arias Laso

I'm trying to install Cyrus in my RH7 (2.2.16-22) box

When I do:
rpm -Uvh cyrus-imapd-2.0.9-3.i386.rpm
I get:
error: failed dependencies:
 libcrypto.so.1   is needed by cyrus-imapd-2.0.9-3
 libssl.so.1   is needed by cyrus-imapd-2.0.9-3

I have openssl-0.9.5a-14 installed, so I try to update it with:
rpm -Uvh openssl-0.9.6-3.i386.rpm
and then I get:
error: failed dependencies:
 libcrypto.so.0 is needed by cyrus-sasl-1.5.24-6

Should I force the installation of openssl-0.9.6-3.i386.rpm, without fear 
of breaking samba, openssh, etc.? Should I stop these services before I 
upgrade openssl?

IMAP server setup - need guidance

2001-04-03 Thread Saul Arias Laso

I have a LAN of one RH7 box and seven Win95/98 PCs. I have DSL access to 
the Internet, using masquerade on a second Linux box. We have one email 
account with an ISP where all of our customer emails are sent. I want to 
setup an email server on one RH7 box so that customer emails can be 
accessed, and replied, from any of the Win98/98 PCs, via Outlook. I 
understand that this can be done by transferring all incoming email to a 
single "mailbox" in the RH7 box, and then running an IMAP server.

I think I have to do this:

1. Install an MTA on the RH7 box. This can be sendmail, exim, qmail, postfix.
2. Install fetchmail on the RH7 box, and run it as a cron job to download 
e-mail regularly from my ISP to the RH7 box.
3. Install an IMAP server on the RH7 box. This can be Cyrus-imapd.
4. Configure Outlook in the PCs to use my RH7 box as their SMTP and IMAP 
server.

I am not running a DNS server, and I understand this is not necessary for 
what I intend to do.

I would like some feedback before I start downloading stuff and messing 
with my system. Specifically, I need to know:

1. Which MTA program should I choose? I understand sendmail is overkill for 
my needs. We receive only around 50 emails from customers each day.
2. Is Cyrus the best choice for IMAP server?
3. Do I need to set up a DNS server?
4. Is there anything else that I need to install?
5. Is there a better approach to solve my problem?

Thanks.

Re: Shutdown -h now will do a reboot on RH7

2001-02-09 Thread Saul Arias Laso

I had the same problem. It turned out to be that the BIOS had an option 
called "Wake on LAN" enabled. This apparently powers up the computer 
whenever it detects any activity in the ethernet card. Look for a similar 
entry in your BIOS and turn it off.
