I wish to send an email from my localhost machine (using PHPs mail function) but I can not do this since I don't have a mail server. In addition, I need to be able to send emails through a network that is heavily firewalled (to what extent I do not know yet). My idea is to make use of "QK SMTP Server 3" and get that to use an external s...
I have a ubuntu server which I've locked down to only HTTP, HTTPS and SSH (port 30000). On this box I have a MySQL server which 99.9% of the time is only used locally. Every now and then I want to connect to the MySQL instance with the GUI tools, but without touching the firewall. Therefore, it is possible to set things up so that I c...
We allow users to dial-in to our system. We run a firewall on the dial-in system that blocks all access by default and we only allow certain servers to be accessed by adding specific rules. We have a web service that contacts our server. The service calls are made over SSL. The SSL Cert is from GoDaddy. We have found that when conne...
I am trying to call a web service from a BizTalk (2006) orchestration. Having got the hang of the basics, I have been following this tutorial (page 74 onwards) in which i have a web reference to an external web service (I am using this web service instead of the one in the tutorial), I have my web message in a Send component, and have ...
Hello. I'm having a little problem with configuring the firewall on my server. I only want a specific range of IPs to be able to access specific ports. For example, I'm having alot of password attempts to some of my servers, so I want to make it more safe by only allowing incoming connections from a specific range of domain. Example: M...
Say, I have two computers behind firewalls, routers, etc (ie. no incoming connections). Is there ANY way I can connect the two through TCP/UDP protocol without everything going through a special server somewhere? I know Skype does something like that, perhaps not exactly. Thanks. ...
I have a problem with the availability of server from the outside (from local network all works perfect). A key problem is the http, where the requests are carried out but only if the response is less than a certain number of KB. - if accessed via browser from the outside, only the request less than or equal to 4KB are responsed - if acc...
I am using OS X 10.5 and I am looking for a way to detect if an application attempts to access the Internet. At this point I would like to block the application if it matches a set of rules that I will define. There is the ipfw Unix command that I realise can be used to block access to certain ports, but that affects ALL applications. I...
Hi, I'd like to setup RMI to pass through port 80 on a java servlet.. (To pass through the firewall) I have a Tomcat server and i'm looking for the module that will catch the RMI http request and pass it to the RMI layer on the server machine. I've read that RMI automatically handles this on it's side. Is there a step-by-step guide to ...
Please I need guidelines on how to fully trust a named instance of SQL Server on a Windows Firewall via its file name. I know how to obtain the named instance installation path from the registry. I need guidance on Windows Firewall API ...
I want to try out some of the MySQL software, like Workbench, on the MySQL Db I develop on at work. After many failed attempts to make the connection, I finally asked one of the server admins if I was doing something wrong and was informed that the Db is behind firewall. So I can use phpMyAdmin, since it's installed server-side, but not ...
Hello, I got access via SSH (root access) to a Machine that's inside a network at my client's office. I'm programming in my computer a PHP application that needs to integrate to LDAP. The LDAP server is in another server at my client's network and not accesible from outside, however I can perfectly access it via the server I can conne...
I've got an SSH tunnel setup on my macbook, like this... $ ssh -o ServerAliveInterval=3 -N -L 22222:gitosis-server:22 [email protected] So I can ssh to localhost:22222 and will end up on the gitosis-server behind the firewall. I've created a local id_rsa.pub file, copied it into the gitosis server(running Centos5), and importe...
When using an instant messaging application like Live Messenger or the desktop client for Google Talk, computers can transfer files between one another. I can't say for sure, but I'm fairly certain that the data being transferred between computers does not go through Microsoft's or Google's IM servers, rather the two computers with the I...
Hello everyone, I want to use WCF to enable two way communication without opening a port on the client. I'm developing something like a P2P application (similar to teamviewer/logmein) where you don't need to open ports to communicate. How do I accomplish two way communication through HTTP/HTTPS without the need to open a port in the c...
I am trying to start and stop the firewall in Windows XP using the win32 api for changing settings in the registry, i.e HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile. I am trying to change a data value but it's not changing. So can tell me any other way how I can stop the fire...
I heard some firewalls and browsers disable cookies, and I think I may have heard blocking POST data. What are reasons a company may want to block cookies? (and alternatively post data. Which I am not interested in ATM.) ...
We have created a WCF using net.tcp with an anticipation that the service can work in a firewall that would accept only HTTP port. The client behind firewall can also access it. Do we need to host the service on a static, public IP so that any client from any network can conect to it? Ideally, we would like to host the service on a no...
I need to control inbound and outbound traffic to/from a linux box from within a C++ program. I could call iptables from within my program, but I'd much rather cut out the middle man and access the kernel API functions myself. I believe I need to use libnfnetlink, however, I have not been able to find any API documentation or example p...
Normally if I run the following the following command in the rhino shell, mbp001:rhino1_7R2 user$ java -jar js.jar Rhino 1.7 release 2 2009 03 22 js> readUrl("http://www.google.com") It will return the resultant html markups. However, if I runs it behind a firewall, it will throw an exception (because it is unable to reach the host)...
