telnet for port 5433 is not working while it works for port 22
Hi,
I am trying to set up a dev environment and I have Ubuntu server (10.16.1.92) and a CentOS VM (10.16.3.235) on this. On the CentOS I have a program running on port 5433. Now my problem is that I am unable to telnet this port from another Windows server whereas I can telnet port 22 from Windows.
How can I enable port 5433 to be telnet(ed) from windows?
I am a developer and dont have much knowledge about resolving this issue.
I am giving below o/p of commands from CentOS VM:
Thanks,

Hi,
Well this is probably a silly one that I should know...but I don't !
I'm telnetting to various ports from a shell script and the telnet is echoing back that it's 'trying xxx.xx.xx.xx...' but not the port number it's trying!
Any help much appreciated

cyclades-devices(5)cyclades-devices(5)NAME
cyclades-devices - tables for driving cyclades-serial-client
DESCRIPTION
The cyclades-devices file supplies all mapping between Unix device files (/dev/*) and the addresses of serial ports of Cyclades Terminal
Servers. It contains one entry for each serial port, with the following format:
device:rastype:rasname:physport:type:options
Note: A # character at beginning of line indicates a comment
The entry fields are:
devname
- A full pathname of the file that will be associated to the serial port. It must start with a "/dev/" preffix. Two naming schemes
may be used here: - devname does not exist, and will be linked to a free pseudo-tty. This is the default behavior of cyclades-ser-
cli. - devname is the name of a valid slave pseudo-tty. In this case, the '-t 1' option must be assigned in options field. (Note:
this option is not supported by this release).
rastype
- Terminal Server type: - prts, for Cyclades Pr302X/TS Terminal Servers. - path, for Cyclades PathRAS Terminal Server.
rasname
- Host Name or IP Address of the Terminal Server where the serial port resides.
physport
- Number of physical port in the Terminal Server. If treated as the IP address associated with this port, in a IP-based addressing
scheme.
type - Server type that will be contacted to handle the serial port: - rtelnet, for Remote Telnet Server - socket, for Socket Server
options
- Per-port specific options, passed to cyclades-ser-cli program.
EXAMPLES
1. Device on a PR3020/TS Terminal Server pr3k Port 1, accessed through /dev/ctty01 device file name, using telnet protocol (remote telnet
server)
/dev/ctty01:prts:pr3k:1:rtelnet:
2. The same device, but with an IP address pr3k_port1 associated to the serial port (IP-based port addressing)
/dev/ctty01:prts:pr3k_port1:0:rtelnet:
3. Device on a PathRAS Terminal Server pr3k Port 2, accessed through /dev/ctty02 device file name, using socket protocol (socket server)
/dev/ctty02:path:pr3k:2:socket:
