I'm looking at migrating from my WIndows 2003 servers at home to Ubuntu 7.10 servers, however I use a lot of ASP and ASP.Net code with connections to MySQL databases. Has anyone played with this? Good? Bad? Otherwise?
any postfix users/gurus out there?
my server ate it the other day and I'm trying to get it back up asap, postfix is just queueing messages instead of delivering them to Maildirs. I spent 8 hours yesterday trying to get it working with no luck. CentOS-5.
If you can help me get this fixed, I'll add paid time on your LJ account or something as a thank you.
help!

Can someone help me with some basic security on my SBS2003 server, with particular regards to e-mail security. I am not idiot but I have not done server or LAN support for a living since NT 4.0 and 95. I spent the last 10 years doing Cisco Networking and Telecom work. I installed and ran a Win 2K server with exchange for a year or so and now SBS 2003 for a few years just to keep some skills up.
I only host a few personal websites and one e-mail domain with just a couple e-mail accounts. I also have a POP3 connector to pull e-mail in from an ISP for an old e-mail address. I run it in my basement on a DSL with static, public IP addresses with a Cisco router acting as my firewall. I am also running Symantec Corporate Antivirus 8.1 and I have Windows Intelligent Messaging Filter configured. I believe I am up to date on all my service packs and updates. I have done basic thing like using hardened passwords and disabled the default administrator account. I admit that I have not changed my passowrd in a while but I changed them today.
One of the main things I am concerned about is unauthorized users sending mail through my server. My girlfriend and I am really the only people that would normally send mail from one of several machines that would all be on the same local IP subnet. I primarily use Outlook to manage my mail, but I have also used, outlook express, netscape, thunderbird and OWA. The main symptom of how i know is that I have a security problem is that I when i go to Exchange System Manager and look at the Queues for my server, I see about 40 SMTP connectors set up for domains that I do not manage or support. All but one have at least one message waiting in the queue. I have frozen them for now, but more will keep getting added and I have know idea how people are able to do it. When I get my daily reports, I have seen that often I get dozens of failed attempts of trying to log into my server via Terminal Services/RDP.
What can I do or or look at to see how my system is compromised and what people are doing or trying to do on my server. What are some other things I can do to improve security on my server and harden it against attacks. Whenever I try to google for tips, I find really in depth instruction that I don't understand or are for more complicated installations. I have done some things in the past to tighten up things and have screwed up my server. So more often then not, i choose to do nothing then risk messing things up.
I just discovered that my IP is listed on a blacklist. Apparently I need an rDNS record before they'll remove me, and I haven't the first clue on how to set one up. I've got the regular forward DNS records set up, but the rDNS stuff just confuses me.
Can anyone point me in the right direction?
Hi There,
I have a new website hosted from my local computer www.americansolarpowercentral.com .
I have a couple problems:
I can't seem to add more pages to my wwwroot folder and have them show up on the web (like www.americansolarpowercentral.com/otherpage.aspx . Is there a setting involved in giving access to more pages?
Also, Google webmaster tools is unable to verify my page. I've added their meta tag to my main page, but no go, and I've put their verify html doc in the wwroot folder too, but it won't verify (likely due to the same problem as above).
Any thoughts?
Thanks!
