connect system call failure saying network unreachable

Hi all,

I have a problem (dont know if it's really so) with connect system call. My application server (which uses tcp) is running and my client is trying to connect to it. But connect system call in client is failing saying network unreachable. But the server to which client is trying to connect is reachable because ping to that server ip gives proper response. The error code which i got upon failure of connect system call is ENETUNREACH.

Can anybody let me know why this happens

Thanks in advance

It seems your firewall is causing issues, you can check the logs to confirm.Since the server is reachable by ping,but system calls fail, there may be a port that is not open on the server or the server is blocking the client ip address.You'd have to check the logs to find more.
