    [ubuntu] Re: A simple /etc/hosts updater script

    Nice script! You could also change the 0.0.0.0 to the IP of a local pixel server. That way you won't get missing graphics, 404s, and empty frames. The local pixel server simply delivers a 1x1...

  3. [ubuntu] Re: Apache occasionally stops responding

    Apache2 also writes various logs. It logs to /var/log/apache2/*.log by default but could be configured to log to another location or could even be disabled. Did you find and check Apache2's logs? ...
  4. Re: What will I be missing if I make the switch from a Mac to Ubuntu?

    That's why virtualization is so popular. It works well, is surprisingly efficient, and is non-OS specific. I run 2 flavors of Linux, OpenSolaris, pfSense, and WinXP all virtualized using VMware...
  5. Re: What will I be missing if I make the switch from a Mac to Ubuntu?

    I've used Linux since 1999. It was my primary OS for everything until I purchased my Macbook several years ago. Now I also have a Macmini and the iMac 27'' core i5. I still run Linux in VMs on my...

    [ubuntu] Re: zone a record

    Assuming both domains point to the IP of your Webserver, then the DNS part is already sorted. What you are asking about is handled by the Webserver software. If you are using Apache2, you would...
  8. [ubuntu] Re: Logrotate causes input/output errors

    Sounds like you have a failing hard disk drive! Get your important data off it as soon as you can and then replace it. I'm betting that the logrotate script is merely triggering the problem due to...

    [ubuntu] Re: DNS help

    First, make sure your server IP address is a static, publicly routable IP and if you can have your provider assign a meaningful reverse delegation for it, all the better. Then, install Bind 9 and...

    [ubuntu] Re: Apache server question

    You could just block access from the offending IP. Open a shell on the server and type:


    sudo iptables -I INPUT -p tcp -s <offending_IP> --dport 80 -j DROP
  11. [ubuntu] Re: all services die but ping still responsive

    [ubuntu] Re: Firewalls - what to use.

    Nope! With no services listening, you have no entrance vector unless you can successfully attack the network stack. Not gonna happen! :)



    This doesn't support your case. How does compiling...

    [SOLVED] Re: Root-User : Unset

    Yeah, I just realized that my suggestion allows LOCAL terminal logins to root without a password so definitely not how it is by default! I'll make a note on my post above.

    [SOLVED] Re: Root-User : Unset

    The following will remove the root account password altogether, thereby making it like it was originally.


    sudo passwd -d root

    [ubuntu] Re: Firewalls - what to use.

    Host-based firewalls on Linux are generally not useful unless you have specific reasons that warrant it. Most users will find that they hinder more than they help. So unless you are running any...
  17. [ubuntu] Re: Help With Ubuntu Server and my Domain name.

    Hence the reason I suggested he be on a static IP! But yes, you can finagle it to work with a dynamic IP if you're willing to tollerate occasional interruptions. Use of a static IP is so much less...
  18. Re: Who is going to stick with 10.04 LTS for the next few years?

    I still have 2 Ubuntu 6.06 LTS servers running strong! :-) They're still supported (although not too much longer) and they still do their jobs very well. When either of those things change, I'll...
  19. [ubuntu] Re: Help With Ubuntu Server and my Domain name.

    You need to be on a static IP with your ISP if you are going to host your own domain (nameserver, mailserver, webserver, etc.). It needs to be a public, routeable IP. Assuming you have that...

    Many personal VPN providers throttle their clients after a determined amount of data or time. I'm not saying that is the case with your provider. But it's not uncommon. Because of that, I opted to...
  22. [ubuntu] Re: How to interpret the 'dates' in rkhunter.log??

    That's epoch time. Unix calculates time as starting January 1, 1970 at 12:00. Epoch time is how many seconds have elapsed since then. So with a little math or a handy utility, you can easily...

    I've used the wvdial utility to do exactly what you are talking about. A couple of Google searches for wvdial should get you up and running in no time. Good luck.
