Networking :: Cannot Access Public Web And Mail Server From LAN Addresses

Aug 5, 2009

I have two nagging problems on one network which I do not have on another elsewhere, both using uptodate Debian servers. The server is on the private subnet behind a router/adsl modem. The symptoms of the one which does not work

1) Users cannot access their web site from lan. If they try, they get to the router web interface, same as if they entered http:10.0.0.138 which is the router's lan address.

2) Users cannot access smtp or pop3 service using the domain name, they can access it only using the servers LAN address.

I fear that I might have not set up the router properly because appart from that the two servers are almost identical but I do not know where I might have made an error.

Ubuntu Servers :: Setup An Outbound SMTP Mail Server With & Using Multiple IP Addresses

Mar 15, 2010

This is the current setup that we have: We have approx 20 clients who pay us to send out a type of e-mail called an E-Blast to their customers. We currently are using 5 Microsoft Windows Virtual Servers to do this. The problem is that those machines are starting to break down. There are times that it will take Microsoft Windows approx 9-10 hours to complete 1 job. This is way too long. We want to move away from Microsoft Windows for this particular type of job as it seems there are more customers who are wanting to use this type of advertising.

It seems that using a Linux Server "Command Line or Shell" environment would be the best way to go as there is no GUI like Windows. Since there is just text...that is something that would/should process very, very quickly.

I am in the process of setting up a new SMTP outbound mail server. This is the current software & configuration (what is installed on this new machine):

All of the customer data (Names, E-Mail Addresses, etc that these e-mails are going to) are currently loaded in a Microsoft SQL Database.

My machine that I am using is plugged into the DMZ. I have 1 ip address for the 1 network card. I have also added/bound 4 more ip addresses to that network card.

I have configured Postfix for Multiple IP Addresses.

I can, from the command line, send successful test e-mails and receive them in my personal account.

As far as I know everything is setup correctly. I can and will post requested information so that it can be verified that everything is setup correctly.

Here are a couple of my questions:

Ensure that I have my Network / Interfaces file and my Postfix's Master.cf/Main.cf files setup correctly?

How can I setup this server to be an Outbound SMTP server and get it to use all 5 of the IP Addresses to send these e-mails quickly?

What can I use to check and ensure that this server is in fact sending out emails on all 5 IP

Addresses (I heard that there is a program named "Postal" that may help in determing this).

Ubuntu Security :: Resolving IP Addresses In Iptables Logs?

Jan 19, 2010

whether iptables logs can be set to automatically resolve IP addresses? I am running the firewall on a network with DDNS/DHCP, and this ability would really help quickly identify hosts with suspect traffic.Failing this, I guess the simplest solution will be to simply set static addresses!

Security :: Unknown IP Addresses In Samba Logs?

Feb 1, 2011

I have a (headless) Debian (Linux debian 2.6.26-2-486) system running on an old Pentium machine in our home network. I use it as a Samba share, among other things.

Ubuntu Security :: Tcpdump: Filtering For Packets From A Site With Mulitple Ip Addresses?

Aug 13, 2011

I want to capture all packets from site "www.examplesite.com" so I checked its ip address in an ip address look up and it was 123.456.abc.def.So I set my filter to "dst host 23.456.abc.def"However I then realised that multiple ip address point to ww.examplesite.com, for example say the following ips also go to987.654.321.000111.222.333.444So is there a filter that will automatically capture all traffic going to www.examplesite.com or do I have to go and manually find all it's ip addresses and pass them all to the filter?

Security :: Iptables - Limit Access To Port 8443 On Server To 2 Specific IP Addresses

Dec 23, 2010

I'm trying to limit access to port 8443 on our server to 2 specific IP addresses. For some reason, access is still being allowed even though I drop all packets that aren't from the named IP addresses. The default policy is ACCEPT on the INPUT chain and this is how we want to keep it for various reasons I wont get into here. Here's the output from iptables -vnL

[Code]...

Note the actual IP we are using is masked here with 123.123.123.123. Until I can get everything working properly, we're only allowing access from 1 IP instead of 2. We can add the other one once it all works right. I haven't worked with iptables very much. So I'm quite confused about why packets matching the DROP criteria are still being allowed.

Ubuntu Security :: Inserting Fake Mail Via Disconnect IMAP?

Apr 1, 2011

After a April Fools' Day joke with fake mails (simply faked by forwarding & changing the text body) I tried to insert "real" fake mail into my online GoogleMail account. It was incredibly simple and that freaks me out a little.

I simply created the mail in Kontact, moved it to the folder I wanted it to appear in and synced - done. Someone with better knowledge might probably even manipulate the Kontact database on my computer and then sync, even changing old mails from years ago.

Is there a way to prevent this or find out that the mail wasn't really e.g. sent but just faked? I'm working at the university as a teaching assistant at the moment and from time to time you have those "No, I didn't miss the deadline, I send the mail with the paper to you" students. It was never necessary until now, but I always thought that I might check that by simply asking the student to show me his or her "Sent" folder in their online mail account. But that won't work if you can insert mails into your "Sent" folder via disconnected IMAP.

Apr 20, 2011

I have a server, running Centos 5.5. It runs daily rkhunter and logwatch. From both I get a daily mail.

I have a desktop computer, running Fedora 13 (almost 14...). It runs also a daily rkhunter and logwatch. But I get ONE mail from logwatch, which contains the result of rkhunter.

On the server, I want also only mail from logwatch, containing the rkhunter results. But so far, no luck.

How can I get the rkhunter results in the logwatch mail on my Centos server?

Security :: Check Mail Via Tor And Browser Says Connection Untrusted?

May 20, 2011

I was recently connecting securely to the website where I have my mail account, and I connected through Tor. When doing so firefox presents me with the screen saying that the connection is untrusted and it can't verify the certificate. So I cancelled. I'm using torbutton and I turned torbutton to off and connected again with no problem. Then with torbutton on again, same thing (untrusted).

Is it possible the exit node I was going through is doing a man in the middle attack? However later when connecting through tor I did NOT get the warning about the site being untrusted. I really don't know what exit node I was using when I got the certificate warning and what exit node I was using when I did not recieve the warning. I don't know how long I stay on the same node or how/when it changes.

Security :: When Sending The Mail A Selinux Error Is Coming?

Aug 19, 2009

i configured sendmail with squirrelmail in RHEL5.3

it is working fine. i can send the mail and receive the mail .

but when i try to send the mail a selinux error is coming[but mail is sending successfully ]. i don't under stand this message.

Quote:

Summary:

SELinux is preventing sendmail (system_mail_t) "read" to eventpoll (httpd_t).

Detailed Description:

SELinux denied access requested by sendmail. It is not expected that this access is required by sendmail and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access.

Allowing Access:

Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for eventpoll,

restorecon -v 'eventpoll'

If this does not work, there is currently no automatic way to allow this access.Instead, you can generate a local policy module to allow this access - see FAQ(url) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended.Please file a bug report (url) against this package.

Additional Information:

Source Context system_u:system_r:system_mail_t
Target Context system_u:system_r:httpd_t
Target Objects eventpoll [ file ]
Source sendmail
Source Path /usr/sbin/sendmail.sendmail
Port <Unknown>
