I just reinstalled debian on my computer, I've had it working for a long time, only difference is I used to have Cable Internet and now I use DSL. Anywho, I reinstalled debian from the kde CD on the debian website, it auto-configured my network out of the box. My network is connected to the computer, pinging google works perfectly, and ifconfig shows that eth0 is working correctly without any errors. However on both Konqueror and Iceweasel, every time I try to connect to a website, it tells me the server cannot be found. Basically it acts like I don't have internet. Using the terminal works though, I have installed KDE-FULL from the terminal and wicd, so I know I do have internet. I don't know what it could be, like I said, I installed from the cd and this happened. Maybe there's a bug on the KDE debian cd

View 2 Replies View Relatedventuring into unfamiliar territory so I'm hoping someone can help me and make things a little more understandable for me. I have setup Postfix on a standalone server connected directly to the internet. I have got inbound and outbound email working for the most part, but I am worried about security.My fear is that if I leave port 25 open to the outside world spammers will find this and start relaying mail through it and eventually blacklisting the IP attached to this box.
For now, I am hosting mail for a single domain and single user (me) with a few aliases. I plan on expanding to IMAP and SMTP access from the outside at some point, but for now I've been using Mutt in a shell and it's fine for my needs for now.
Here are my current Postfix settings:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

how to do a small script that checks if what the users entered is an ip address or not? Also possible to do the same but instead of an ip address is a netmask. For example the user entered: 192.168.0.1 so its true this is an ip address, if it doesn't look like an ip address then is false And second example, the user entered: 255.255.255.0 so the script returns true, and if its not a netmask the script returns false.

I have installed a LAMP server with Postfix as mail server. The scripts send email as user www-data using the mail server on the same machine.
However, the email got rejected by external mail servers (failed reverse DNS check) so I setup a mail server that meets all needed requirements.
Now I would like to use this second server instead of the mail server on the LAMP server. I found that this could be done with changing sendmail settings in php.ini (I think).
However I am not sure how that will go: www-data is no actual user on the new email server (which requires authentication before sending). Do I need to create a new user on the email server or change the settings in php.ini to match an existing user?
I would like to implement something when a server is offline for whatever reason. For example. I got my own DNS servers and webservers. I would like it if the users goes to www.somedomain.com and the server it is actually on is down for maint. or For whatever not able to respond. What can be done so that if the server isn't able to be contacted that it can point to either a another server or the dns somehow can display a page stating who to contact to report a problem or to let them know its down for maint. And can goto a site to check the status or whatever.

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
