Telnet in script Connection closed by foreign host
Hello,
I'm trying to learn and automate some tasks via a script, but my first ever script failed with "connection closed by foreign host" error. I checked the other discussions but it didn't help. Could you please help?
The following options work without script;
# telnet x.x.x.x
# telnet
> open x.x.x.x
The script also works for other in-band connection IPs, which directly request user and password without viewing any system info.
We connect this node over auxiliary port via a modem. On putty x.x.x.x 23 connects to our device and x.x.x.x 22 to our server. I got some wireshark captures; the TELNET session continues negotiation, and suddenly interrupts.

Please wrap all code, files/data, input & output/errors in CODE tags.
It makes it easier to read and preserves multiple spaces for indenting or fixed-width data.

create_foreign_data_wrapper
CREATE FOREIGN DATA WRAPPER(7) SQL Commands CREATE FOREIGN DATA WRAPPER(7)NAME
CREATE FOREIGN DATA WRAPPER - define a new foreign-data wrapper
SYNOPSIS
CREATE FOREIGN DATA WRAPPER name
[ VALIDATOR valfunction | NO VALIDATOR ]
[ OPTIONS ( option 'value' [, ... ] ) ]
DESCRIPTION
CREATE FOREIGN DATA WRAPPER creates a new foreign-data wrapper. The user who defines a foreign-data wrapper becomes its owner.
The foreign-data wrapper name must be unique within the database.
Only superusers can create foreign-data wrappers.
PARAMETERS
name The name of the foreign-data wrapper to be created.
VALIDATOR valfunction
valfunction is the name of a previously registered function that will be called to check the generic options given to the foreign-
data wrapper, as well as to foreign servers and user mappings using the foreign-data wrapper. If no validator function or NO VALIDA-
TOR is specified, then options will not be checked at creation time. (Foreign-data wrappers will possibly ignore or reject invalid
option specifications at run time, depending on the implementation.) The validator function must take two arguments: one of type
text[], which will contain the array of options as stored in the system catalogs, and one of type oid, which will be the OID of the
system catalog containing the options. The return type is ignored; the function should indicate invalid options using the ereport()
function.
OPTIONS ( option 'value' [, ... ] )
This clause specifies options for the new foreign-data wrapper. The allowed option names and values are specific to each foreign
data wrapper and are validated using the foreign-data wrapper library. Option names must be unique.
NOTES
At the moment, the foreign-data wrapper functionality is very rudimentary. The purpose of foreign-data wrappers, foreign servers, and user
mappings is to store this information in a standard way so that it can be queried by interested applications. One such application is
dblink; see in the documentation. The functionality to actually query external data through a foreign-data wrapper library does not exist
yet.
There is currently one foreign-data wrapper validator function provided: postgresql_fdw_validator, which accepts options corresponding to
libpq connection parameters.
EXAMPLES
Create a foreign-data wrapper dummy:
CREATE FOREIGN DATA WRAPPER dummy;
Create a foreign-data wrapper postgresql with validator function postgresql_fdw_validator:
CREATE FOREIGN DATA WRAPPER postgresql VALIDATOR postgresql_fdw_validator;
Create a foreign-data wrapper mywrapper with some options:
CREATE FOREIGN DATA WRAPPER mywrapper
OPTIONS (debug 'true');
COMPATIBILITY
CREATE FOREIGN DATA WRAPPER conforms to ISO/IEC 9075-9 (SQL/MED), with the exception that the VALIDATOR clause is an extension and the
clauses LIBRARY and LANGUAGE are not yet implemented in PostgreSQL.
Note, however, that the SQL/MED functionality as a whole is not yet conforming.
