Server :: Looking For Gateway With Central Control System
Jun 4, 2010
Basically I'm working as part time administrator in a company, and still am at college. To keep the story short, the company I work with used to have a linux gateway, namely Untangle. We tried to upgrade to E-Box, which is supposed to have more options than Untangle, but it doesn't seem to work as it should. What I'm trying to ask here is this. I need a gateway system that handles QoS, Content filtering, Mail Filtering, DNS, Wan failover / load balancing, LOGS (important), Firewall and maybe the handling of separate users or groups. The ideal solution would be one that like the E-box, has a central control system, without the need to adjust code in CLI for configuration. I have some experience on CentOS and Fedora, so I am able to do some configuration, like installing Samba, DHCP and VNC.

I have several (say, 50) machines running ubuntu.I want them to be centrally controlled.That is, each machine should get permit from central machine before installing any software etc.I googled quite a lot but could not find the solution...

I can very well configure squid transparent proxy on gateway server.But i want the squid transparent proxy on non-gateway system as i already have hardware firewall installed.i.e i want to redirect all the traffic coming through my gateway (hardware firewall) 192.168.200.1 to my squid server 192.168.200.3 on port 3128.How it is possible? Without transparent proxy by directly giving proxy ip in browser i can access internet but how to do it in transparent mode?

We have several SLES, CentOS, Fedora server and use logmail to filter the logs on our central syslog-Server. The problem is, that the filtering take more and more time and the configuration gets more and more confusing. What program to use to analyse our central logfile? Something mysql based?

I am trying to build a ftp server with vsftpd. In general, I am not able to log in. I can only log in to the ftp server, if that same user is logged in to the server. I found out that this has to with my network setup. I am using OpenLDAP for centralized authentication and home directories are stored on an NFS server. The problem is that regular users are not allowed to log in to servers, therefore their home directories are not mounted. However I want to be able to give my users access to the ftp server without their home directories mounted. Is this possible with vsftpd and if so how do get this up and running. By the way, anonymous users are not allowed.

We are hoping to build a central database server so that we can take all the singular instances of mysql off our web servers and have the data stored in one place (we also run a number of syslogging servers that use mysql, netflow servers that use mysql, and many other servers that have mysql tables that we would like to consolidate as well). Now I have run into the problem that requires all the customer web sites to change the configuration for their connection to the mysql server from a local connection to a remote connection, which is something we are trying to avoid. I am wondering if there is a software suite or a function of mysql itself that allows you to present the remote database information as local databases to a server, allowing customer configurations to remain intact, as if the mysql server never moved off the local machine? Or a different question, can you configure mysql server to take local requests and forward them to a central mysql server?

In my network Nagios server running on Ubuntu server and working fine. I am able to monitor servers in local network through plugin and SNMP. Now I want to monitor some servers which are located remote location(network) and they haven't real IP(all are behind route/firewall). I can allocate real IP to nagios server if require. How can I monitor those servers?

I tried hard so that I can stay away from version control but in almost good job specifications, I find version control as requirement. So I thought I had to start from somewhere. I always tried to read it but haven't got much luck with it. So I have few problems to ask. I am confused and I really want to know how can I use version control in my context and how will my working environment change with it.
I have Linux VPS Server. I use capnel/whm to create sites in php/joomla. So is version control a software or script which I can install on my linux box like ./configure. Or I have to install it on every site like any framework I use Dreamweaver to edit files via FTP. Now if I install version control then do I still use same method to edit files or then method gets chnaged What about the database like MySQL will it stays same or its also version controlled Will version control make my system slow and how much space it uses on my server.

I'm looking for a Syncronizacion Softwares (running as a daemon) to do a unidirectional syncronization of some files/folders from a lot of servers to one central server.As there are a lot of servers i want a software that only needs to be installed on the central server and pulls the files/folders from the other servers.rsync and unison need to be installed on both machines and syncronize the files/folder by sending them from al the servers to the central server(its no the central server the one who pulls the files/folder from the other servers), so they dont work for what i want.

I have a network gateway system which runs redhat 7 (2.2.16)
Firewall running is ipchains
Internal network is eth0 192.168.5.1
External network is eth1 99.99.99.98 (example add)
My problem when I change the static address of the external network from 99.99.99.99 to 99.99.99.98 I am not able to connect to internet. From my preliminary investigation ip is not binded to network card., but I am not sure, is there a way to check binding accurately
Below is the ifcfg-eth1 file contents
DEVICE="eth1"
USERCTL=no
ONBOOT="yes"
BOOTPROTO="none"
NETMASK="255.255.255.0"
IPADDR="99.99.99.99"
IPXNETNUM_802_2=""
IPXPRIMARY_802_2="no"
IPXACTIVE_802_2="no"
IPXNETNUM_802_3=""
IPXPRIMARY_802_3="no"
IPXACTIVE_802_3="no"
IPXNETNUM_ETHERII=""
IPXPRIMARY_ETHERII="no"
IPXACTIVE_ETHERII="no"
IPXNETNUM_SNAP=""
IPXPRIMARY_SNAP="no"
IPXACTIVE_SNAP="no"
I have updated the address change in ipchains firewall scripts. Before IP change network was work fine with this firewall scripts.

we have several servers working on 172.15.2.X series .Our mail server ip is 172.15.2.4 & plateform is linux as it is squirrelmail server.other server which have the same series of ip are working on win2k3 plateform.however I try to recognise this problem by iptraf tool but can't get positive result.
Sometime the ip of all 172.15.2.X series could not ping from outside and LAN as well .
We has been temporarily resolving this problem by
1 changing gateway on all servers as well on firewall.
OR
2 change the ethernet card on mail server and configure same ip on new one .however we have only two NIC card on mail server .The problem resolved temporarily for one OR two hour after it same problem on that card also.than again we have to do same step on switching on another NIC card and reconfigure IP and do down first one.
OR
Take shut down for few time the mail server. But by these all above are not permanent solution BKZ After few hours mailserver starts blocking the gateway again. Than we want to know that what issue can be with this server
1 Are we need to configure VLAN?
2 Is that hardware problem?
3 Is this traffic overflow problem whcih is chocking the gateway of whole network machine having same gateway?
I am sending the few attachment to you please revert ASAP.But keep in mind one thing that attached document indicate the good running mailserver configuration.may be you could not found any problem in this conf.
In order to resolving this problem I have tried by changing duplex mode to
1 > 1000 MB/ps full duplex utonegotiation off
&
2 > 1000 MB/ps full duplex autonegotiation on
but can' get positive Result. I have also tried by IPbinding but it was useless. I think some thing wrong is happening in mailserver which make gateway chocked and 172 series server got also affected by this because they could not get path of gateway as it got choked by mail server's over broadcasting .Although I have make ready the old mailserver it is working but it is cabinet server & not reliable so please suggest for that problem.

I have been beating my head for the last few weeks on this problem, (although I have been taking the wrong approach, it seems).
I need a gateway to direct web traffic to three separate servers/domains. I have been trying to do this with both a dns server and , (seperatly), apache server to forward requests. The dns server was a no go, and <i can only get apache to redirect http and ftp.
After Googling this ALOT, I believe that what I need is a gateway server to redirect my traffic to the 3 different servers. I have been reading about using using nat and iptables for this and was wondering if anyone had any advice/suggestions on this. The other thought I had was to use something like pfSense to create the gateway, but I am still reading the documentation, and I am unsure if this approach will work.

I got 2 servers, each on different locations (server 1 and server 2). I want all traffic on server1 included web browsing, applications etc., be always going through server2, like a gateway. I want the traffic to be encrypted (maybe use VPN?) So if I browse, or any logs pick up ip adresses from applications used by server1, I want it to display the IP address from server2 (Might be the wrong way to say it).
I always wants server2 to act as an firewall and logserver that logs all the traffic. I was thinking about using Snort for IPS/IDS solutions and OpenVPN for the traffic, but what can I use as a firewall? Most firewalls I find on google has its own OS/Distribution. Maybe Squid for logs? But squid does not support much protocols. Distribution on both servers are updated Debian/Ubuntu based.

I just set up a linux server which is acting as an internet gateway. For specific reasons, clients first make a vpn connection trough the internet to the linux server.
CLIENT ---->Internet----->Linux VPN Server ------> Internet
On the linux server iptables is configured for NAT. The problem is that the internet speed becomes slower than expected. I used windows and RAAS and the speed was pretty good. The server has only 1 NIC(eth0) and an alias interface is added to eth0. The alias is eth:0 with ip address 192.168.0.253
iptables config is as follows:
iptables -P INPUT ACCEPT
iptables -F INPUT
iptables -P OUTPUT ACCEPT
iptables -F OUTPUT
iptables -P FORWARD DROP
iptables -F FORWARD
iptables -t nat -F
iptables -A FORWARD -d 192.168.0.0/24 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -s 192.168.0.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j SNAT --to MY_VALID_IP

setup 2 gateway in my email server(opensuse).
now i wan to setup 2 internet lines for my email server, which mean that either one of the line is down, i still can receive mail from another line.
Example
Internet line 1 = ISP1
Internet line 2 = ISP2
my email server got 3 nic which...
eth0 = 192.168.1.2 (255.255.255.0) (from ISP1 GW 192.168.1.1)
eth1 = 192.168.2.2 (255.255.255.0) (from ISP2 GW 192.168..2.1)
eth2 = 168.168.1.2 (255.255.0.0) (connect to local LAN)
now existing GW set on the server is 192.168.1.1, mail receive and send through ISP1. now we wish to set somethings that once the ISP1 line is down, the server will auto switch to ISP2 gateway and continue send and receive mail without manually change of settings

I have set up qmailtoaster as a gateway for exchange.
my smtproutes contain this:
thedomain.com:mail.exchange.com
and my rcpthosts contain:
thedomain
The problem I am facing now is, the exchange was able to send mails through me alright. But when mails come in, qmailtoaster is suppose to forward the mails to the exchange server but it is not, rather the mails are sitting in the toaster's queue.
