I would like to try and answer your question but I'm completely confused. We need a lot more information to even start to think about it.

However, let me state a couple of facts here (to prompt you to tell us more).

1. Your laptop ip address is 192.168.8.149 and your server address is 192.168.121.72 so if your subnet mask is (typical) 255.255.255.0 then these two addresses are NOT on the same network and so your laptop will send the connection request to its configured gateway. (You could try changing your laptop ip address to 192.168.121.xxx to see if it connects then).

2. You specify a port number on a connection command line when you know that there is a listener on that port number at the other end for the network protocol/service that you are using. If you have a particular service listening on port 8081 then that port number is not also going to work for telnet protocol. By default (ie, without specifying a port number) telnet uses port 23. So you would not specify a different port number on a telnet command line unless you KNOW that a telnet listener is configured on port 8081 at the other end. Telnet will fail to connect otherwise.

If you know all this already then I apologize for not understanding your question but please provide much more information.

Q: Can you ping your target ip address? If that fails then fix that first.

Ns_UrlToFile(3aolserver)				   AOLserver Library Procedures 				  Ns_UrlToFile(3aolserver)

__________________________________________________________________________________________________________________________________________________

NAME
Ns_SetUrlToFileProc, Ns_UrlIsDir, Ns_UrlIsFile, Ns_UrlToFile - URL to file mapping procedures SYNOPSIS
#include "ns.h" void Ns_SetUrlToFileProc(char *server, Ns_UrlToFileProc *procPtr) int Ns_UrlIsDir(char *server, char *url) int Ns_UrlIsFile(char *server, char *url) int Ns_UrlToFile(Ns_DString *dsPtr, char *server, char *url) _________________________________________________________________ DESCRIPTION
These functions map URL paths to real files and directories. They are normally used to determine whether a given URL has a corresponding file or directory and to return the real filesystem path that corresponds to the URL. Ns_SetUrlToFileProc(server, procPtr) Set a pointer to a custom routine to use in place of Ns_UrlToFile. Ns_UrlIsDir(server, url) Construct a directory name by appending the URL to the current AOLserver pages directory for the specified server. Return NS_TRUE if the directory exists; NS_FALSE otherwise. Ns_UrlIsFile(server, url) Construct a file name by appending the URL to the current AOLserver pages directory for the specified server. Return NS_TRUE if the file exists and is a regular file; NS_FALSE otherwise. Example: /* IsFile - Simple request to determine if an URL is a file. */ int IsFile(Ns_Conn *conn, void *ctx) { int isfile; char *server; server = Ns_ConnServer(conn); isfile = Ns_UrlIsFile(server, conn->request->url); if (isfile) { Ns_ConnReturnNotice(conn, 200, "File", NULL); } else { Ns_ConnReturnNotice(conn, 200, "Not a File", NULL); } return NS_OK; } Ns_UrlToFile(dsPtr, server, url) The Ns_UrlToFile function writes the full path name of the file corresponding to the given URL. The result is appended to the Ns_DString. The function does not check that the file exists or is readable by the AOLserver process. This function returns a status of NS_OK or NS_ERROR. Normally this prepends the pageroot to the URL path. If you have created your own custom routine and used Ns_SetUrlToFileProc to point to it, your routine is called instead. This could be used to create, for example, a module that takes the given URL and maps it to a file in a different way than the default Ns_UrlToFile routine. Example: /* A simple page fetch request function. */ int SimpleFetch(Ns_Conn *conn, void *ctx) { Ns_DString ds; FILE fp; char *server; Ns_DStringInit(&ds); server = Ns_ConnServer(conn); Ns_UrlToFile(&ds, server, conn->request->url); fp = fopen(ds.string, "r"); Ns_ConnSendOpenFp(conn, fp, -1); fclose(fp); Ns_DStringFree(&ds); return NS_OK; } SEE ALSO
