I missed that ping bit, but the error that the OP is getting isn't what should be returned if there is firewall blocking. Like porter said, telnet should quit with "connection refused" kind of error.
And I have another question, what ping command are you running? I have seen the Solaris ping command return "is alive" when run like this:
ping server-x
server-x is alive
But the command has failed when run like this:
ping -s server-x
:
no output - while it actually should throw:
64 bytes from server-x (x.x.x.x): icmp_seq=0. time=0.285 ms
64 bytes from server-x (x.x.x.x): icmp_seq=1. time=0.243 ms

socket_connect
SOCKET_CONNECT(3) 1 SOCKET_CONNECT(3)
socket_connect - Initiates a connection on a socket
SYNOPSIS
bool socket_connect (resource $socket, string $address, [int $port])
DESCRIPTION
Initiate a connection to $address using the socket resource $socket, which must be a valid socket resource created with socket_create(3).
PARAMETERS
o $socket
-
o $address
- The $address parameter is either an IPv4 address in dotted-quad notation (e.g. 127.0.0.1) if $socket is AF_INET, a valid IPv6
address (e.g. ::1) if IPv6 support is enabled and $socket is AF_INET6 or the pathname of a Unix domain socket, if the socket fam-
ily is AF_UNIX.
o $port
- The $port parameter is only used and is mandatory when connecting to an AF_INET or an AF_INET6 socket, and designates the port
on the remote host to which a connection should be made.
RETURN VALUES
Returns TRUE on success or FALSE on failure. The error code can be retrieved with socket_last_error(3). This code may be passed to
socket_strerror(3) to get a textual explanation of the error.
Note
If the socket is non-blocking then this function returns FALSE with an error Operation now in progress.
