RemoteHostIP snafoo

I am writing a fairly basic chat programn using winsocks in vb6. To do testing, i am using a PC with ethernet and a laptop on a wireless connection. I'm not sure how the network is structured (i.e., what goes on with the wireless connections) because this is a college campus. However, when i have the laptop connect to the PC, the RemoteHostIP property of the server winsock on the PC contains an address that is not the IP of the laptop. I need this property to keep my connections straight, so any insights would be very helpful.

If you are connected from pc to laptop then winsock.remotehostip will return the ip of the connected pc\laptop\etc, it may be an issue with the network setup, ie the ip you are getting is the routers ip, try doing winsock.localip from the laptop and seeing if it matches the winsock.remotehostip from the pc.

The clientwinsock.localip and the ip given by the ipconfig command prompt on the laptop both give one address. The serverwinsock.remotehostip on the pc gives a different address. I am familiar with winsocks and how to set them up; this is a case where a machine thinks it's ip is one thing, but computers that it connects to think it's ip is a different thing. I checked, and the two computers have different subnet masks, that may be the problem.

Hmm, sounds like a network issue.

Hope you solve your problem, is this post now resolved? If so could you add the http://www.vbforums.com/images/ieimages/2004/10/1.gif to your first post :)

try putting the server on the laptop. Also what's this ipconfig thing? how do you find the ip straight from your computer?

send email to yourself, and look there

ipconfig is a dos command, you can use it in the command prompt. There are other ways of checking your IP via the network connections section on the control panel, but i use ipcondig because it's usually simpler to get to.

**************************************************
USAGE:
ipconfig [/? | /all | /renew [adapter] | /release [adapter] |
/flushdns | /displaydns | /registerdns |
/showclassid adapter |
/setclassid adapter [classid] ]

where
adapter Connection name
(wildcard characters * and ? allowed, see examples)

Options:
/? Display this help message
/all Display full configuration information.
/release Release the IP address for the specified adapter.
/renew Renew the IP address for the specified adapter.
/flushdns Purges the DNS Resolver cache.
/registerdns Refreshes all DHCP leases and re-registers DNS names
/displaydns Display the contents of the DNS Resolver Cache.
/showclassid Displays all the dhcp class IDs allowed for adapter.
/setclassid Modifies the dhcp class id.

The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid, if no ClassId is specified, then the ClassId is removed.

Examples:
> ipconfig ... Show information.
> ipconfig /all ... Show detailed information
> ipconfig /renew ... renew all adapters
> ipconfig /renew EL* ... renew any connection that has its
name starting with EL
> ipconfig /release *Con* ... release all matching connections,
eg. "Local Area Connection 1" or
"Local Area Connection 2"
**************************************************

How do you view the IP address from Network Connections? (unless it is static?)
