How To Securely Work With Your Remote Site From An Unsecure Network
Nov 20, 2007
If a network administrator decides sniff on you and do some damage on you, can you securely work from that network with your dedicated hosting server (I mean here using fpt client and ssh client to work on your system)?
If yes, what are the security steps one should follow in such an environment?
Can ftp and ssh clients be trusted in such an environment and if yes what ftp and ssh clients would you recommend?

Attached is a (badly) drawn diagram of two sites, connected by a vpn.
The site to the left, is network 10.0.0.0/24 which runs a linux server as the router for the network.
The site to the right, is network 10.1.0.0/24 which runs a windows 2003 server as the router for the network.
Now, my problem is, the clients behind the windows 2003 server can ping any machine on the first network because i setup a static route to route all traffic to 10.0.0.0/24 over the vpn interface.
now, my problem is, only the linux server can ping any machine on the windows 2003 network, any client behind the linux server cant seem to route over the interface.
I have the following route on the linux server: .....

I have a remote XP PC: 172.16.1.5 OpenVPN connection with route added for 192.168.2.0/24 to go via the VPN
Now on the other end the network consists of:
I have a OpenVPN server inside the lan on 192.168.2.245
Its default gateway is 192.168.2.1
I have 3 Windows Servers, 192.168.2.246, 247 and 248. All gateways are set to 192.168.2.1.
I have a ethernet router on the network, 192.168.2.1, it has a route added for 192.168.0.0/16 to go via 192.168.2.245, and route added for 172.16.0.0/24 to go via 192.168.2.245 also). the 192.168.0.0/16 is incase any other LANs are connected at a later date, if computers saw any packets not on the the 192.168.2.x subnet they would be routed to the default gateway which would then pass them to the OpenVPN router.
The trouble is, i can remotely connect and ping to the OpenVPN router fine and also the ethernet router, however when i ping any of the Windows boxes it times out. But i can open up Remote Desktop and connect to the windows box without problem, infact if i am running 'ping 192.168.2.246 -t' it will suddenly come alive but only after the RDP connection is made.
Is this something funny with the routing? I want to keep the OpenVPN server internal to the network and i appreciate it is hitting the ethernet router then being passed to the OpenVPN but something is weird as it fires up RDP fine but not ping. No firewalls are enabled on any of the boxes. If i log into ssh on the OpenVPN router or ethernet router i can ping from that to the windows boxes fine.
Its as if a ICMP redirect is issued, and all is well after the 1st connection. Not too sure but could anyone be kind enough to enlighten me?

Like the title says, I just moved my site over to my own server, and it is running cpanel. Anyways the main site [url]works, but [url]does not.
What is really strange is, [url]works fine as does [url]
So I figure there is something I have to do to get it all to work right.
The other issue is that if you are logged into [url]but goto [url], you are not logged in anymore, but if you go back to the original link, then you are still logged in. This happened on the other guys server before with the main site as well.

I plan on starting a social networking website similar to facebook using this script: www.socialengine.net
After talking to a host gator associate he mentioned that the only way to get it up was to buy a dedicated server because they won't allow it on any of their shared plans
My question is, which host/plan would you recommend for this particular project...we won't be offering photo albums and such but are expecting quite a bit of traffic and don't want the site to slow down or crash..also, any tips for a first timer?

I changed my sites IP address via cpanel, but now it doesn't show up in a web broswer, I check out cpanel's website for information about this issue, and they posted this:
"It may take up to 48 hours for DNS servers to register the change and the site may not be associated with the new IP address during that time period."
is that true? change the sites IP address will take 48 hours to show up? I figured since it was all local IP stuff, it'll be a instant change and working instantly. since the name servers are all the same, ect.
anyone shed some light. I just wanted to know if I should give it a day to start working? or as of right now, I feel like I need to fix a cpanel error... but if its true, then everything is ok

my website is hosting at our local server.
Everyone can view the site at [url]
but, for the people behind the router in the network can't view the site with that URL or static IP. we can only view the site with local IP of server.
Apparently, the reason is configuration something while setting up the server.

Starting point: a working site using a shared IPv4, dedicated IPv6, and SSL. HTTP and HTTPS work, the latter only using SNI of course.
The good news: If I simply allocate an IP resource of 1 to a subscription it is pulled from the pool, assigned to the service node, assigned to the web site, DNS is updated, and the site is automatically changed to using a Dedicated IPv4 and Dedicated IPv6.
The bad news: visitors land on the default web site of the service node, with the default SSL certificate.
Other info: I can't ping the new IP, even though it shows in "ip a l" and /etc/sysconfig/network-scripts/ifcfg-eth0:0. [edited]
After the IP assignment, it is still installed, and /etc/httpd/conf/plesk.conf.d/ip_default/domainname.conf shows the new certificate is being used.
However, a second set of VirtualHost entries is created in server.conf for this IP for ports 80 and 443, with NameVirtualHost enabled on the new IP. The port 443 entry uses the default certificate. Apache's setup this default VirtualHost entry will override the web site configuration because Apache is listening on port 443 with the wrong cert.
If I go to "Change webspace settings" and toggle to Shared IPv4, Dedicated IPv6 the site works again via HTTPS, and Dedicated IPv4 and Dedicated IPv6 breaks it again. Setting the SSL cert to None and back again does not work.
Setting the SSL cert to None, changing to a dedicated IP, and enabling SSL results in the server being inexplicably inaccessible...browsers no longer connect to either the default site or the correct site, and I don't see any entries in the vhosts's logs.

I have windows servers that I'll be co-locating very soon. I have purchased a Dell 2161ds-2 and an APC remote boot power strip. Could someone please tell me the best way to secure remote access to these products. Do I put them on public IP's and allow them through the firewall or do I put them behind the firewall and access them after I authenticate through the firewall.

I'm on a short assignment to inventory and manage the fixed assets of a small company, and we've just bought a web-based database for this purpose. While I'm pretty good at administering/running local databases, the web part has me stymied. Our company is between IT people, and there's no one on site with any more idea than I have about what's going on!!
Here's what I have so far:
--The company has a website which I'll call "ourwebsite.org" -- which I think, from searching the IP address the website points to, is hosted by HostMySite.com.
--There's also a record in DNS Management with the same name (ourwebsite.org), but pointing to our little server's local IP address.
--I need to find a way to get my database -- which I can access on the network at (server's IP address)/database (ie 0.0.00.0/database) -- online. I tried creating records in DNS Management (for ex., assets.ourwebsite.org) that point to our server's IP (the one that, if I type it in on the network, I can get to the site I'm looking for), but get generic "can't find the page" or "can't connect to the server" errors, even after 72 hours, when trying to access it from off the network.
--If I browse to assets.ourwebsite.org/database on the server itself, I get to the website! But if I go to that page from any other computer, on or off the network, it doesn't work.
--The Server is running Windows Server 2003
So, what are my options? Do I have to talk to the HostMySite.com people to add this page? Shouldn't I just be able to use my server's name (ourcompanyadc.ourcompany.org) and have that route to the server? What's going on here! Is there a simple way to get a tiny local-server-hosted website online outside of the network?

I just transferred a domain from one cpanel box to another.
Now, that site is showing someone else's page. I've seen this happen before, but I cannot remember the fix.
the virtual host in httpd.conf is fine, shows proper IP, username, docroot, etc
Dns zone is fine as well.
The domain is using the server's main IP, so that's not the cause.
Centos 5 / cpanel 11 / apache 1.3 / php 4x

I'm having exec cgi issues,
CentOS 5.3 x86_64, Linux, Apache/2.0.63,
cPanel 11.24.4-R36167 - WHM 11.24.2 - X 3.9
Error is,
[an error occurred while processing this directive]
If I "uncheck" IncludesNOEXEC in Apache Global Configuration the error disappears, but the SSI doesn't work. If I check it the error is there, but the SSI works.
Here's what I have done so far,
Through WHM,
Main >> Service Configuration >> Apache Configuration,
Pre Main Include, Pre VirtualHost Include, Post VirtualHost Include,
I added,
Options +Includes
AddType text/html .htm
AddType text/html .html
AddOutputFilter INCLUDES .htm
AddOutputFilter INCLUDES .html
Options +ExecCGI
AddHandler cgi-script .cgi .pl
I also added this to the httpd.conf
<Directory "/">
Options +ExecCGI FollowSymLinks Includes IncludesNOEXEC Indexes -MultiViews SymLinksIfOwnerMatch
AllowOverride All
</Directory>
Options +ExecCGI
AddHandler cgi-script .cgi .pl
Then I tried,
Options +ExecCGI
AddHandler cgi-script .cgi .pl
in the .htaccess file

After spending nearly 4 days trying to get ftp working on my server i still haven't achieved it. I got a server with a default install of plesk and cent os 4. I update to 8.2 and when i first go to try ftp it says "server closed connection" on my ftp client.
So then i tried updating 8.2 again and the installer failed. So i tried manually installing both proftpd and pureftpd via ssh and yum and it fails to install. I've also restarted the server a few times. I've tried logging in with every single username/domain/i.p. assigned to the server. and i've had no luck.

how does SSH work and really what is it.
This is my knowledge, I may be wrong or right:
There are two ways of controlling your server, through control panel and through SSH, now SSH is where you type in codes to control your server.
Now from what I know you can't login to SSH alot due to security reasons.
I was wondering, if I have a forum can I login to SSH everyday to back up the database?

Okay, I have been trying to get a VPN network setup here between our DC and our office for weeks now and have not been sucessful.
Here is our goals:
-use 10.x.x.x/255.0.0.0 as a local backend network at our DC
-be able to assign a 10.x.x.x address at the office to all workstations and be able to access any of the local machines at the DC
-we have a asterisk server that we use and want to run that on the same network, asterisk box at the DC, phones at the office
We are wanting to impliment this for allot of security procedures and for ease.
But I also want to be able to have this like at my house so I can still be on the VPN. I want to have my house, office and DC always connected and then setup remote ability too to dial in via VPN.
What would be the best way to accomplish.
I have already tried having a few Linksys RV082 and WRV54G but the remote and local networks must be different networks, so this will not work here.

I bought another dedicated server yesterday and it was bought online same day. It was working fine yesterday during a few site transfers but now it would appear that I am losing network packets.
I have done a traceroute and ping tests and attached are the results. Please can anyone help. I think the problem is to do with NTT's network rather than server problems but please could someone else ping from their location to confirm this.
