yes port 23 are open by defualt but I tend to disable port 23 because it is insecure.
I use ssh intend which uses port 22, ssh (secure socket hosts) encrypted data and password using rsa or dsa keys while telnet port 23 send data and password in clear text.

iscsi_discovery(8) System Manager's Manual iscsi_discovery(8)
NAME
iscsi_discovery - discover iSCSI targets
SYNOPSIS
iscsi_discovery <IP> [-p <port>] [-d] [-t <tcp|iser> [-f]] [-m] [-l]
DESCRIPTION
Perform send-targets discovery to the specified IP. If a discovery record is generated, try to login to the portal using the preferred
transport (-t flag specifies the requested transport type, TCP is the default). If login using a certain transport succeeds, mark the por-
tal for automatic login (unless -m flag is used), and disconnect (unless -l flag is used).
For iSCSI discovery to work, open-iscsi services must be running. i.e. iscsid should be up, and the iSCSI modules loaded. This is best
accomplished by the init.d startup script.
[-p=]port-number
set the port number (defualt is 3260).
[-d] print debugging information.
[-t=]transport-type
set transport (default is tcp).
[-f] force specific transport - disable the fallback to tcp (default is fallback enabled). force the transport specified by the argument
of the -t flag.
[-m] manual startup - will set manual startup (default is automatic startup).
[-l] login - login to the new discovered nodes (defualt is false).
