"The Oracle" on "The Centos" ?   there's many software products from 
Oracle, and several versions of CentOS.   You should probably be a 
little more specific.

I have installed Oracle Database Server Enterprise Edition 9i and 10g on 
CentOS 3, 4 and 5, it runs just fine.IIRC (its been a few months 
since I've installed any of them), you need to do a fair number of 
manual steps, you should follow the Oracle release notes on running 
RDBMS on RHEL.

Why are VPS's any more affected than bare-metal machines?

It will be greatly ironic if Redhat release the fix after they release 5.4, or 
as part of 5.4. I will try not to say I told you so.

[CentOS] to filter dos ip using iptables recent

[MontyRee]

Hello, all.
 
I read this document about iptables recent module.
http://blog.andrew.net.au/2005/02/16#ipt_recent_and_ssh_attacks
 
and I would like to filter the excessive spam mail sending ip address by 
iptables recent module.
and some questions.
 
iptables -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --set --name 
SPAM
iptables -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --update 
--seconds 60 --hitcount 4 --rttl --name SPAM -j DROP

 
If I set like above, 
 
I can't understand the meaning of the hitcount.
it means the number of a packet, session or connection?
 
above rule means if 4 connection for 60 seconds, the ip will be filtered for 60 
seconds, right? 
 
if some ip was filtered, how long will be filtered? for 60 seconds?
 
when I see the list as cat /proc/net/ipt_recent/SPAM
the maximum number is 100. if it reaches the 100, no problem?
and how to increase the number? 
 
 
Thanks in advance.

Maybe the manpage will help:

--hitcount hits
This option must be used in conjunction with one of --rcheck or
--update. When used, this will narrow the match to only happen when the
address is in the list and packets had been received greater than or
equal to the given value. This option may be used along with --seconds
to create an even narrower match requiring a certain number of hits
within a specific time frame.

Nearly, but there is no timeframe implication on the filtering. It
simply decides whether the given packet matches the rule and takes the
appropriate action. The timeframe comes from whether (or not) there have
been 4 or more connection attempts from that IP in the previous 60 seconds.

See above - it's the previous 60 second timeframe you are looking at.

You should follow the Oracle installation guide.
http://download.oracle.com/docs/cd/B28359_01/install.111/b32285/toc.htm

Mind you, as far as I know Oracle is not supported on CentOS so if you
run into problems with your databases, you're stuck. On the other
hand, we have plenty of development environments (Centos 4 and 5)
running Oracle 10g and 11g w/o any issues. For production, you should
have RHEL or OEL for support.

[CentOS] OT: Strange message in root e-mail possiablly hacked!!! Not sure??

[Lee Perez]

Morning all,

Little back ground.  Running CentOS 5.3 fully update.  I basically run 
this as router and gateway for home network.  I have two(2) winblows 
machines hooked up.  I am running samba for shares.   I opened up root's 
mail this morning and found this strange little comment :

Connections Denied:
lib/access.c:check_access(327)  58.239.84.158 : 1 Time(s)
smbd/process.c:process_smb(1062) 58.239.84.158 : 1 Time(s)

So I started looking around in /var/log.  I looked at my secure logs and 
saw nothing out of the ordinary.  I looked in samba and found a log file 
58.239.84.158.log.  I opened it up and it said the following:

[2009/08/15 06:31:34, 0] lib/access.c:check_access(327)
  Denied connection from  (58.239.84.158)
[2009/08/15 06:31:34, 1] smbd/process.c:process_smb(1062)
  Connection denied from 58.239.84.158

There is nothing on this server that I can not replace.  Did I just get 
hacked?  Should I wipe this thing and start over?  Any and all advice is 
greatly appreciated!!!

Thanks.

I don't think you got hacked.  You might want to check your firewall
settings though.  It *looks* like your firewall is letting netbios
connections from off your LAN -- you should not be allowing this!

It does look like someone from 58.239.84.158 (SK Broadband Co Ltd in
Seoul) tried to check out your samba shares, but was denied access.

Are you trying to install express edition? Express edition is only available in
i386, so you will have to install i386 libraries or just install i386 version of
centos.

He can do better. Why is samba bound to an Internet facing interface at 
all? Unless you have a need to allow smb/cifs connections over the 
Internet, samba should never ever be allowed to bind to an interface 
with an Internet ip.

My MTU is already set to 1492. Can you explain the relationship between 
internet access and the log entries?

You may get some additional clues if you can find out what is querying
gconfd.  What application are you using to manage your networking
configuration?  Do you have a DSL modem only, or a combination
modem/router?  Is your CentOS box plugged directly into the DSL
device, or are you using wireless or any additional router?

My suspicion would be that either (1) your DSL drops and the log
entries above are from the network management software when it
attempts to restore the connection, e.g. re-obtaining DHCP token; or
(2) the network software itself fails and restarts, which seems less
likely.  There are additional possibilities if there's a wifi
connection, etc.

Check the load on the machine - make sure  gconfd isn't consuming most of the
CPU during the apparent Internet outage.

Those are just debug messages from the gconf database routines that  
save your preferences.

I doubt they are actually related to your Internet communications  
problems.

It's either an issue with the ISP or your pppoe configuration.

If you eventually decide to wipe it and start over, you might consider
running IPCop Linux, a special distribution for Firewall/Router
purposes. I use it at home and some on the list use it at work.
The fewer services you run, the safer it will be. Samba as someone
said, probably should not be run on a firewall. http://www.ipcop.org/
 The version currently available has been around for awhile, but they
have a new version in testing. I have IPCop running on an old box with
a Pentium 233 MHz MMX chip and 64 MB of RAM and it's headless.HTH

Are you running denyhosts? By default I think it only covers ssh, but
you can configure it to cover other protocols.

[CentOS] advice needed about "554 Too many recipients"

[Rudi Ahlers]

Hi all,

A client of ours just requested to increase the max_recipients in Exim
to 300, since he keeps getting "554 Too many recipients" error when
sending a marketing email from MS Outlook.

Before you tell me to use Pine / Mutt / etc to send plain-text emails
via mailman, this isn't an option.

I would like to know, what are the implications of increasing the
default 100 to 300? If 300 email recipients were added to the "To:"
field, does it establish 300 connections to the SMTP server, or not?

In the Exim documentation
(http://www.exim.org/exim-html-current/doc/html/spec_html/ch14.html#SECID105)
I found this:

"If this option is set greater than zero, it specifies the maximum
number of original recipients for any message. Additional recipients
that are generated by aliasing or forwarding do not count. SMTP
messages get a 452 response for all recipients over the limit; earlier
recipients are delivered as normal. Non-SMTP messages with too many
recipients are failed, and no deliveries are done.

Note: The RFCs specify that an SMTP server should accept at least 100
RCPT commands in a single message."


But, this doesn't tell me if it will have a performance issue with the
server, or if other mail servers will have problems with our mail
server sending the email to so many recipients in one go.

Can someone give me some pointers on this one?

Locally between Outlook and Exim, no, this won't establish more than
one connection to the SMTP server.  If Exim is acting as a smart
relay, it'll get one copy of the message with the whole list of
addresses in one transaction.

On the "other side" between Exim and the eventual recipients of this
mail, the likelihood is that Exim will make one or two connections per
destination domain.  If all 200+ recipients are at the same domain
(say, all yahoo.com addresses) then Exim may run into problems, but
it's not very likely.

However, if that list grows very much larger, both you and your client
are going to be a lot happier if the client stops attempting to send
out his own marketing mail with Outlook and instead engages a
reputable email service provider.  Assuming, that is, that he has
appropriately confirmed permission to send email to all those people.

I've been in Solaris land for the last 5 years and my rpm skills aren't the
most current; how is this achieved?

firefox-3.0.10-1.el5.centos
firefox-3.0.10-1.el5.centos

[r...@canthus ~]# rpm -e firefox-3.0.10-1.el5.centos
error: "firefox-3.0.10-1.el5.centos" specifies multiple packages

Re: [CentOS] DNS Server Recommendations

[Chuck]

I recommend a highly secured master that is not queried by any clients
(preferably in a network/vlan your clients can't even access)... then
configure one-way zone transfers to 2 or more slave servers which you
configure your clients to point to. Maintain your zone files in rcs of some
sort... For IP control/delegation and DNS control/delegation I recommend IP
Plan.

Of course bind is the 800lb gorilla in the DNS world... don't even think
about putting DNS on windows.

I don't recommend any front ends being that a few hours well spent reading
the docs and man pages will make you a dns expert in no time. Bind is very
easy to learn and shouldn't take longer than an afternoon at best.

[CentOS] ssh-agent autostarting

[Dave]

Hello,
I'm trying to get public key authentication working on a client to
server connection so i can drop passwords. I've got the keys in place and
confirmed they are working. I'm now trying to set up ssh-agent, I read i can
do it manually i was looking for a more automated method for users on login.
This is not through a gui.
Thanks.

Thanks!

Just curious, why are the 2 identically named packages? Is this just an
oversight/bug on CentOS's part or does it serve some purpose?

ROTFL.

Yes, the 800 pound TURTLE. Old and slow.

Too bad no one has made rpms for djbdns, daemontools and tools to manage 
tinydns data with a sql backend and a nice web frontend.

I never wrote the above and your reply to the OP via my post makes it 
look like I did.

  I looked in samba and found a log file

[CentOS] priority plugin and httpd/php

[Dave]

Hello,
I'm running centos 5.3 with the priority plugin enabled. One of my
3rd party repos has updated httpd and php packages that i want to get,
however it won't overwrite the base packages of httpd* and php* since they
were installed from base. How can i update just these specific packages
httpd* and php* without changing my priority options?
Thanks.
Dave.
