  1. I just found this in something I was reading. I kinda think it could explain it, but I'm still not using IPv6 I don't think so I still don't see how the solicit even got to me. "When the TCP/IP protocol initializes and DHCPv6 has been enabled on any of the client machine's interfaces, the DHCPv6 client sends a DHCPv6 Solicit message to the All_DHCP_Relay_Agents_and_Servers multicast address specified in [RFC3315] to discover the available DHCPv6 servers. The DHCPv6 client includes a Vendor Class Option that contains information about the host, such as the operating system version." If the solicit was being sent out to a bunch of addresses in order to find a server, then I guess that could explain why I got one. But I would imagine it would be sending IPv6 addresses, not IPv4, so I still don't really see how it would be sent to me.
  2. So I was using wireshark and saw some DHCPv6 protocols that were sending solicit messages. As I understand it, from what I've found through google, this is something that a DHCPv6 client would be sending to a DHCPv6 server. I'm not running a server nor am I using IPv6 even, so I don't really get why this is in my traffic. If someone could explain why I might be seeing this that would be awesome.
  3. Yeah, I thought that it worked at first but it actually didn't haha. I'll give the workstation a try. I still want to try to get the oracle virtualbox working though, I like the feel of it, it is definitely better than the VMware Player.
  4. Well I got the DHCP server up and running. Finally found this site which helped me with the ip.
  5. OK so I tried VMware server but had some trouble setting it up in Ubuntu. From what I read it seems like I'm not the only one who has had trouble with it. So I decided to give oracle virtualbox a try. So far it seems more promising. I have one question though. I'm setting up an internal virtual network on it, and adding a DHCP server. It seems that I have to give an IP address for the DHCP server. How would I find out what ip I should give it? Can I just make one up? Once I get over this hump I think I'll finally be able to get my virtual machines connected.
  6. Thanks. The virtual network editor sounds good. Um, I can't really seem to figure out how to use it though. I don't see it anywhere. Is it like a virtual app I need to download?
  7. I am trying to connect two virtual machines in VMware Player to teach myself how to use metasploit. As such, I want to make sure the two virtual machines are only connected to each other and can't actually get online. I'm very new to metasploit and I want to make sure everything is contained. From what I understand, I think I can create a virtual serial port to connect them through.The problem is that I don't fully understand how to do this. If I go into the Virtual Machine Settings, then click the add button, bringing up the add hardware wizard, I get an option for setting up a serial port. If I choose serial port and hit the next button, I am then given the options of a physical serial port on the host (I think this is the one I definitely don't want to do), output to file, and output to socket. I've tried to find some info on this myself, but can't seem to find anything I can make sense of. If anyone could explain these different options, how to set them up, or explain what I want to be using to make sure none of this stuff gets out of the virtual machines, I would be very grateful.
  8. Sweet, I'll be sure to check them out. Once I'm up to the point where I'm ready that is, still pretty inexperienced with stuff like this. I've been watching your assembly language primer and buffer overload stuff and really like it. Your site has great vids. Thanks for posting them and keep them coming!
  9. Yeah, that would be the easiest/best thing to do I guess. The problem is my mom wants some pics and stuff from it. I was thinking maybe I could scan it from a Ubuntu live cd, try to clear some of the virus stuff that way, at least enough to get on and get these pics and whatnot, and then I could reformat. Does that make sense? I guess I would scan the individual files I took off it again to make sure they are ok before I do anything with them.
  10. So, my mom recently acquired my deceased grandmothers computer, and wanted me to hook it up to our television so we could watch netflix. I installed Ubuntu hoping to just do everything on that and avoid having to take care of her xp os for a while, but as I soon learned you can't run Netflix on a linux system because the movie industry is stupid. So on to the real problem, this xp is seriously messed up. I started by trying to install AVG, hoping I could get rid of a good amount of the stuff right off the bat with that. After dling the free version of AVG, it told me I needed to uninstall McAfee because it was interfering. I did this and then rebooted. Go to run the AVG installer, and what do you know, I get a pop up informing me the AVG file has been infected and the comp freezes. This is where I'm at right now. I wanted to get some input from you guys before I try anything else and possibly screw things up more. So, what do you think my next step should be, try to dl the free AVG again in safe mode or something? As a side note, soooo happy I've switched to Ubuntu on my rig and don't have to deal with this shit on there.
  11. Ok, so one more post and then I promise I'll let this die gracefully. I actually ended up using the commands he did to compile and run or whatever. One slight difference I found was that my randomize_va_space was set to 2 and not 1. I don't really know what that means, I'm running Ubuntu 10.04 by the way if that helps. Anyway, this wasn't a problem or anything, I'm just kinda wondering why 2 instead of 1 and what that means? I also found that I had to enter sudo -i I think it was to actually enter the root instead of just sudo before I could use the echo 0 > command to turn off the randomizer for the stack. Also since this is the Newb section I thought I'd state the obvious and mention that you probably don't want to actually turn this thing off on your real system. I did it on a VMPlayer Ubuntu. I think it might not matter much as long as you set it back, but I didn't want to take any chances.
  12. *Never mind I figured it out. If anyone is interested though, I was able to just do all of this in the Terminal without adding or changing anything. I thought that because it says Assembly# in the thing he is writing in, I would have to somehow switch into some form of "Assembly Mode" thing in my terminal or use something other than the terminal before I could use those commands. I did however use somewhat different commands for the c codes, which I found here: http://www.ubuntugeek.com/how-to-install-c-and-c-compilers-in-ubuntu-and-testing-your-first-c-and-c-program.html I don't know if I needed to use that instead of what he does but it works so I'm happy.
  13. So I'm watching this video, Assembly Primer for Hackers: http://www.securitytube.net/Assembly-Primer-for-Hackers-%28Part-2%29-Virtual-Memory-Organization-video.aspx I'd like to follow along with the steps he is going through, but he doesn't explain what he is running the C programs and the Assembly stuff in. I see he is using that PuTTY thing in the video, but when I looked it up it said that it was like a terminal for accessing other computers through the internet or something. If anyone could explain to me what sort of setup I would need to do what he is doing, or point me somewhere with some information about it I would be very grateful.
