What Email Scanner Gateway

Apr 10, 2009

What type of free email scanner gateway that you are using? I am using SA, Clam and Qmail. It's a little old and w/o the GUI for client to manage the settings.

I'm thinking to switch to something with GUI. Perhaps the combination of Exim, SA, Clam, MAilScanner and a GUI.

Nov 6, 2009

CSF install the new version, I warned that the option Check for cxs. I had a few questions!

1 - is it free? And can be installed and will work?

2 - I like these things are additional to the installation?

3 - a bit about this new possibility to explain how to solve the case to get out of the red.

Illegal Content Scanner

May 20, 2009

While reading a lot of posts and blogs about hosting, I just wanted to ask if someone has an idea on how to find files with illegal content.

I just tried a few bash scripts, but if there are a few thousand files, most of them stop working or produce server loads that stop the whole server.

Is there any software already out there or any script to scan the content on server for phrases?

Google Dork Scanner - Find Vulns?

Mar 25, 2008

Anyone use this poorly coded thing?

Goolag Scanner coded by CULT OF THE DEAD COW/cDc communications

Ive been using it for a bit, but i don't have any vulns on most of my box's.

Anyone else find this thing effective?

Ive passed it onto a few clients, seem to entertain them doing there own basic google powered security scans.

Here is a quick download; Goolag_Scanner_1.0.0.40_Setup.exe

Ive pulled a few results on other large sites, some interesting data thats spread out on google, strange how the crawlers get into it?

1.2 Software

To understand Goolag Scanner, it is important to understand how "dorks"
work (see 1.4) and with that, to establish the use of dorks as an
acceptable tool for information security experts, penetration testers,
and practical paranoids.

1.4 Terms And Abbreviations

* Dork = A detailed search pattern - heretofore used with Google's
search engine - that uses Google to show untapped results for web
sites previously indexed by Google.

The intention of a dork is to find results that might show
information relevant to security issues and/or confidential data.

From our point of view, dorks are not limited to Google. Frankly,
they are malicious patterns that apply to most search engines.

* gS = Goolag Scanner

* cDc = CULT OF THE DEAD COW/cDc communications

Emails Not Displaying Mail Scanner Headers

Sep 14, 2008

i installed the latest version of the mail scanner on my linux server. It has been tested to be scanning and running properly. But one thing that is unusual is that the emails that is being processed by the mailscanner does not get tagged as its being processed by it. Hence i do not really know whether it has been processed.

When i check the email full headers, i am missing information like spam score, spam information and spam status. I did a check in the mailscanner.conf and the configuration was done correctly.

how can we set these information to show on the email header that it has been processed.

PHP To SMS Gateway

Feb 21, 2007

setting up something that would run via php and then send SMS when its called to do so.

I would need a mobile line attached to the server and then I am a little lost.

Currently what I do is that I have my own monitoring script, then when somethings goes wrong, it emails to one of my email accounts and then it SMS me of the contents. But their service is not always reliable so was wanting to setup something on my own end.

Adding In New IP And Gateway

Jul 21, 2008

My server in the datacenter has to migrate to new IPs. Is it feasible to add new ip and gateway and have that operating on eth0 -- doing it remotely?

The dc said I can have both IPs concurrently working for the next 10 days or so.
But, I'm still unsure if I can safely set the new ip and gateway on the server remotely.

Any help would be appreciated. Of course, I have logged a ticket to see if they will set my new primary ip from the console and all the virtual interfaces ...

But, would like to know for my own information if this process is doable remotely.

Gateway Setting

May 12, 2007

I have signed up a new rack and the provider give me the following information:

Service IP address assigned:
Default Gateway: 10.0.0.193
Assigned WAN IP: 10.0.0.192/30
LAN IP Block: 172.16.0.192/27

*first three digits of IPs are changed.

In Windows 2003, I can use the LAN IP with Default Gateway and I can browse the net without problem (with warning though). But, when I configure the Cisco switch (2950), it didn't allow me to use gateway that is in different subnet. I have checked the LAN IP Block and it seems that all IPs in that subnet can be used. Could you teach me how to config the switch and the other servers?

Wireless Authentication Gateway

May 12, 2008

I'm doing a project for my school ( a small technical college) and we're trying to come up with some sort of wireless authentication gateway. This doesn't need to be locked down and super secure, this is a state run school with an open wifi network. Basically we want all wireless users to be forced to view a splash page/AUP and agree to it before being able to access the web.

couple issues:
-Super low budget, so enterprise solutions are pretty much out of the question
-must be as transparent as possible to the use: no MAC registering with the IT dept. no added software, no RADIUS certs etc.
-we have limited access to the actual router and all administration but be done by the upstream provider(including inter-vlan routing)

I've looked at NoCAT and really like it but because of the existing network topology its going to be hard to force all traffic through a central box for filtering/auth

What I'm wondering is if there is a way to do selective DNS poisoning to redirect all lookups to a web authentication server(similar to nocat's system). After a host is authenticated their DNS would resolve correctly. I know someone could just go out by IP or potentially use different DNS servers but we really aren't that concerned about it, all they have to do is click 'accept' anyway.

Using Postfix As An SMTP Gateway

Nov 14, 2007

I have been trying to determine if I should use Postfix or Exim for our new SMTP gateway. My biggest obstacle is in trying to determine if Postfix can handle the processing as efficiently as Exim.

Basically we have hundreds of domains that will have email going through the gateway. I need to know if Postfix can be configured to perform different actions based on the recipient domain (i.e. block receipt of message or add a header and deliver). It looks like this functionality is handled by using a 3rd party tool like "amavisd".

The problem is that it looks like I have to wait for the DATA to be received before I can send the mail to the filtering tool rather than just waiting until the last RCPT command. It is also unclear as to whether the message will be denied during delivery with a 550 error being returned or whether the message is accepted and a postmaster message is sent. Obviously I would prefer the 550 error.

Setting Up An SSH Gateway Server For Techs

Jun 15, 2009

I've been battling with this issue for days now, and I'm sure the solution is simple, so hopefully someone can guide me.

Basically this is my server setup:

1) Tech Server

2) Server 1

3) Server 2

The tech server hosts the main company website, billing, etc. It is also used as the SSH gateway to get into the other servers. Server 1 and 2 host end user websites.

The tech server has an "id_dsa" key on it for the root user.

Server 1 and Server 2 have the public key in authorized_keys

I am able to access Server 1 and Server 2 from the tech server when logged in as "root". However - when signed in as a standard user (i.e. "nick") I am unable to use the id_dsa key to login to the remote servers.

I've tried setting the HostKey variable in the sshd_config file but that wasn't it. I also tried adding the "-i" command to my ssh command.

The only solution I found was to put the id_dsa file under each standard user account (i.e. copying it to /home/nick/.ssh) - however - that's not very secure.

In a nutshell - how do I get standard SSH users to be able to use the root id_dsa key without being able to view it

2 NIC - Set Default Gateway - Crossover Cable In Use

Apr 24, 2007

I have a Linux Server (CentOS 4.4) running, it has two network cards.

1. Onboard 100MBit (eth0), uses DHCP to obtain IP, this card is the only one that is able to connect to the internet.
IP: 192.168.1.13
Subnet: 255.255.255.0
Gateway: 192.168.1.1
Bcast: 192.168.1.255

2. PCI Gigabit card (eth1), uses static IP, and is connected to my Windows machines via a CROSSOVER cable.
IP: 192.168.2.2
Subnet: 255.255.255.0

Symantec Gateway Server Appliance

May 22, 2007

I'm getting a Gateway Server Appliance 5420.

512 MB RAM
2.0 GHz Celeron
40 GB HD
6 Ethernet Ports
LCD Front Display

and it's an appliance like the Cobalts but for security, however I was wondering if anyone knew of a way to just use it as a regular either windows headless server or linux server. Also does anyone know if it's possible to upgrade the processor? Maybe even a Xeon as I know all the other models come with Xeon Processors or do they actually use a seperate motherboard?

Plesk 12.x / Linux :: 502 Bad Gateway Using Nginx

Oct 30, 2014

Today at 12.50 pm my (ubuntu 14.04.1 LTS) server running plesk 12.0.18 suddenly stopped serving websites. Any attempts to access a webpage on any vhost returned the 502 bad gateway using Nginx error messsage.When I looked at the nginx logs, I found messages like:

2014/10/30 14:48:00 [error] 3099#0: *101 connect() failed (111:

Connection refused) while connecting to upstream, client: m.m.m.m, server: , request: "GET /server-status HTTP/1.0", upstream: URL....

Restarting apache & nginx (/etc/init.d/apache2 restart & /etc/init.d/nginx restart) made no difference and I had to reboot to restore http access.

Strangely if I browsed with port 7080 specified (i.e. http://n.n.n.n:7080), this worked fine for all vhosts, so apache (which I believe is listening on this port while nginx listens on port 80) is working fine - nginx is just not able to pass stuff to it?

Also, when i try to enter Webserver Configurations Troubleshooter, i get 502 Bad Gateway nginx error.In the /var/log/sw-cp-server/error_log i get this error:

When i try to insert a Plesk License, i also get this error:

I followed this KB article 118757 but no luck. Also, the server resources are at the lowest usage and there is >2 TB disk space available.

Plesk 12.x / Linux :: 502 Bad Gateway Nginx

Jun 23, 2015

We have a problem with a magento website. Often (perhaps when we use administration), we have the message "502 Bad Gateway nginx".

We have added server instructions in Plesk Nginx:
proxy_buffers 16 16k;
proxy_buffer_size 32k;
fastcgi_buffer_size 32k;
fastcgi_buffers 16 12k;

But we have still the problem.

We have tried :
[URL] ....
And
[URL] ....

Without results...

The log file say:

[client x.x.x.x] client denied by server configuration: /var/www/vhosts/domain.com/httpdocs/app/etc/local.xml

x.x.x.x is the website IP.

Foundry Bigiron: Duplicate Gateway IP Address

Local Connetion With Static IP's What Is The Gateway Address

Jun 1, 2009

we have two servers; webserver and database server connected directly to each other via a standard cat6 cross-over cable. I am setting up their static IP's and have a few questions.

Both are running windows 2003. I went and setup the static ip's as follows:

[webserver]
IP: 192.168.200.1
SUBNET MASK: 255.255.255.0
GATEWAY: {blank}
DNS1: {blank}
DNS2: {blank}

[database server]
IP: 192.168.200.2
SUBNET MASK: 255.255.255.0
GATEWAY: {blank}
DNS1: {blank}
DNS2: {blank}

So DNS being blank is fine since there is no need for DNS, all communication is local (no internet). But should the gateway address be blank?
