telnet of all the possible ways is probably the least useful for this, as you can't set a timeout properly, nor get a meaningful, parseable output. Better would be
Installing nmap
If that's not possible using netcat/nc, installing it if possible
If that's not possible using the socket feature newer versions of bash support
And only if nothing of these is useable resort to telnet
I'm need to connect to another host in a script using the telnet command. How do I pass the login and password to be able to connect to the other host from within the script? (10 Replies)

Hi All,
I was trying to use telnet in a script to access a certain processor on a certain port to view some processes. The problem is that when I use telnet the output is displayed for me.

Hi Guys,
How do I write the script for the following
telnet 192.168.1.100 9002
if the result is less than 1 second. The script should say as port open
if the result takes more than 3 seconds. The script should display as port closed.
Thanks,

Hi all,
I would like to write a ad hoc shell script that would allow me to do some telnet tests to multiple IP's and ports at the same time . So, I want to determine which one is successful and which one fails. So, basically I would like the shell to spawn the telnet test and to break out of... (3 Replies)
Hello,
I wrote a script for doing telnet.However the requirement got changed and now I have to write a telnet script that will
1. Do the telnet from all the virtual ips in a box(Ex: x.x.x.x is the box ip, and x.x.x.1,x.x.x.2 etc are virtual ips associated with that box.)

UMAD_GET_PORT(3) OpenIB Programmer's Manual UMAD_GET_PORT(3)NAME
umad_get_port, umad_release_port - open and close an InfiniBand port
SYNOPSIS
#include <infiniband/umad.h>
int umad_get_port(char *ca_name, int portnum, umad_port_t *port);
int umad_release_port(umad_port_t *port);
DESCRIPTION
umad_get_port() fills the port structure with the IB port attributes specified by ca_name and portnum , or the default port if ca_name is
NULL and portnum is zero. If only one of ca_name and portnum are specified, the other is used as a filter. For example, passing a NULL
ca_name and 2 for the portnum means get a port from any of the local IB devices, as long as it is the second port. Note that the library
may use some reference scheme to support port caching therefore umad_release_port() should be called before the port structure can be deal-
located. The argument port is an umad_port_t struct, as specified in <infiniband/umad.h>.
typedef struct umad_port {
char ca_name[UMAD_CA_NAME_LEN]; /* Name of the device */
int portnum; /* Physical port number */
uint base_lid; /* Base port LID */
uint lmc; /* LMC of LID */
uint sm_lid; /* SM LID */
uint sm_sl; /* SM service level */
uint state; /* Logical port state */
uint phys_state; /* Physical port state */
uint rate; /* Port link bit rate */
uint64_t capmask; /* Port capabilities */
uint64_t gid_prefix; /* Gid prefix of this port */
uint64_t port_guid; /* GUID of this port */
} umad_port_t;
umad_release_port() releases the resources that were allocated by the umad_get_port() function for the specified IB port.
RETURN VALUE
umad_get_port() and umad_release_port() return 0 on success, and a negative value on error.
