    Greetings:

    I just got Palm VNC 2.0 from http://palmvnc2.free.fr/ working on my Treo 600; it it matters, I'm running the Ultra VNC Server on the Windows 2000 machine.

    It appears to be an awesome tool; and I'm still impressed that you can (albiet slowly) see the Windows 2000/XP desktop on your Treo 600 screen.

    I have an IP range question (notes up front, question towards the end).

    According to http://www.arin.net/whois/index.html, Sprint is using IP addresses from 68.24.0.0 to 68.31.255.255 for their PCS services.

    I don't know if I have a static or dynamic IP, but my IP per http://www.whatismyip.com/ has remained constant (granted, I only have the Treo 600 for about two weeks).

    However, when I ssh (Mocha SSH using SSH protocol 2) to our servers, the IP our server sees, while belonging in the same Sprint PCS IP range, appears to be a subset of that range bearing the host of spcsdns.net.

    My goal is to secure the VNC usage to as narrow an IP range as possible without blocking me out as I travel.

    I've noticed the IP our server sees has changed twice in two weeks while http://www.whatismyip.com/ reports the same (but different than the other two IP's).

    My guess is that Sprint PCS proxies my IP, and is using a range based on what spcsdns.net broken down by area (one of the two IP's the server saw was from area1.spcsdns.net).

    Question: Does anyone know the subset range within 68.24.0.0 - 68.31.255.255 that Sprint Uses for spcsdns.net services?

    Thank you.

    Anyone have ideas of where to look next; and, if not, the answer?

    Thank you.

    HI, Not to sound like a moron, but can you reframe your question in Englush?? Obviosly you are much more tech minded then I am. However, I always want to learn new things. Thanks and take care, Jay

    Greetings:

    Basically, I want to know the exact range (if possible) of IP addresses that Sprint actually uses to represent the Treo 600 (or similar PCS Vision usage).

    Sprint PCS has a broad range of IP's, but from the limited testing, I can see they are using a subset of those IP's.

    I would like to know the subset.

    Why?

    With the answer, I can have tighter firewall rules with fit more with the reality of the IP's being used.

    Thank you.

    I think your best bet would (if you got good skills) be to call up SPCS and harass the rep until you get a level2 tech. (Perhaps harass isn't the right word? hah!) and then ask your question to that person

    But then again, I don't have SPCS, so I don't know how it works

    The slightly-more-accurate way to find out what your IP may be is to go to the Network preferences panel, and go into the Log command in the menu. From there it will tell you your IP address, gateway, DNS servers, etc., as well as allow you to ping (I believe typing help and hitting enter will give you a few commands you can use).

    Hope this helps a bit.

    Happy New Year Rufo:

    Great idea. I didn't know that stuff was back there in the advanced settings.

    I need to see if I can correlate the IP's with the primary HA and secondary HA; but I know have a better starting point.

    Thank you.

    Your best bet is to call sprint. Ask for a manager then get them to get someone from the network operations on the line (they will not want to do this as they do not normally talk to end users) You have to explain that this is the 5th time you have called and have not received the info you need. Eventually they will get one of them on the line and they should be able to give you the information you need.

    Hmmm....why don't you look at the reverse. From the reverse it looks like sprint may break their address space in areas. ie.

    Non-authoritative answer:
    255.255.31.68.in-addr.arpa name = 000-526-333.area4.spcsdns.net.

    From there you could probably infer block sizes /24 or /25 etc. then you will have your range.

    I'm just guess...but it seem logical to me.

    BTW what SSH program for the treo 600 do you use?

    I don't know about your proxy theory....proxy/nating a public ip is stupid if you ask me. But I do find it wierd that whatisipaddress and you servers are seeing two different addresses...maybe your browser is caching something.

    I use Snappermail with my own Linux, and have my own firewall. I only allow very specific things in, and track them all quite thoroughly.

    You can find a devinitive list of all Sprint IP addresses in this thread, accurate as of Yesterday.

    http://discussion.treocentral.com/tc...-t45862/s.html

    Note: This is accurate for Pittsburgh area, and it's been accurate every time I travel. I know this because when I get an IP address not in my firewall I can't do anything with my Linux box because it blocks it, so I have maintained a list of IP addresses for everything including the Treo.

    Also note that when you use the Blazer browser (with the 300 at least) I believe there to be a transparent proxy server that intercepts your traffic and reduces the quality of the images etc, so if you are using web tools to identify your IP, you might be seeing the IP of the proxy you are bouncing through.

    mk3cn4 uses a Treo 600 with ReqWireless Web Browser (others are useless IMO), Snappermail, Xiino, PalmVNC... and is a big infone fan. Cheaper and magnatudes better than Sprint's 411 ripoff, www.infone.com.

    One thing you have to be aware of... your browser will show the ip address of your proxy server (if you use one) not the Treo. The best thing to do with VNC is to connect your server with VPN first and then run VNC inside it. I am looking at Mergic VPN to do this. Microsoft Servers support VPN connections and if you want free, Linux can do VPN as well with some configuring...
