I would like to try and answer your question but I'm completely confused. We need a lot more information to even start to think about it.

However, let me state a couple of facts here (to prompt you to tell us more).

1. Your laptop ip address is 192.168.8.149 and your server address is 192.168.121.72 so if your subnet mask is (typical) 255.255.255.0 then these two addresses are NOT on the same network and so your laptop will send the connection request to its configured gateway. (You could try changing your laptop ip address to 192.168.121.xxx to see if it connects then).

2. You specify a port number on a connection command line when you know that there is a listener on that port number at the other end for the network protocol/service that you are using. If you have a particular service listening on port 8081 then that port number is not also going to work for telnet protocol. By default (ie, without specifying a port number) telnet uses port 23. So you would not specify a different port number on a telnet command line unless you KNOW that a telnet listener is configured on port 8081 at the other end. Telnet will fail to connect otherwise.

If you know all this already then I apologize for not understanding your question but please provide much more information.

Q: Can you ping your target ip address? If that fails then fix that first.

scanssh(1)						    BSD General Commands Manual 						scanssh(1)

NAME
scanssh -- scans the Internet for open proxies and SSH servers SYNOPSIS
scanssh [-VIERph] [-s scanners,...] [-n ports,...] [-e excludefile] addresses... DESCRIPTION
ScanSSH scans the given addresses and networks for running services. It mainly allows the detection of open proxies and Internet services. For known services, ScanSSH will query their version number and displays the results in a list. The adresses can be either specified as an IPv4 address or an CIDR like IP prefix, ipaddress/masklength. Ports can be appended by adding a colon at the end of address specification. Additionally, the following two commands can be prefixed to the address: random(n[,seed])/ The random command selects random address from the address range specified. The arguments are as follows: n is the number of address to randomly create in the given network and seed is a seed for the pseudo random number generator. split(s,e)/ The split command is used to split the address range in several unique components. This can be use to scan from serveral hosts in parallel. The arguments are as follows: e specifies the number of hosts scanning in parallel and s is the number of the host this particular scan runs on. The options are as follows: -V Causes scanssh to print its version number. -I Does not send a SSH identification string. -E Exit the program, if the file containing the addresses for exclusion can not be found. -R If addresses are generated at random, this flag causes the program to ignore excluded addresses from the exclude file. The default behaviour is to always exclude addresses. -p Specifies that ScanSSH should operate as a proxy detector. This flag sets the default modes and default scanners to detect open proxies. -h Displays the usage of the program. -n ports,... Specifies the port numbers to scan. Ports are separated by commas. Each specified scanner is run for each port in this list. The default is 22. -s scanners Specifies a number of scanners should be executed for each open port. Multiple scanners are separated by commas. The fol- lowing scanners are currently supported: ssh Finds versions for SSH, Web and SMTP servers. socks5 Detects if a SOCKS V5 proxy is running on the port. socks4 Detects if a SOCKS V4 proxy is running on the port. http-proxy Detects a HTTP get proxy. http-connect Detects a HTTP connect proxy. telnet-proxy Detects telnet based proxy servers. -e excludefile Specifies the file that contains the addresses to be excluded from the scan. The syntax is the same as for the addresses on the command line. The output from scanssh contains only IP addresses. However, the IP addresses can be converted to names with the logresolve(8) tool included in the Apache webserver. EXAMPLES
The following command scans the class C network 10.0.0.0 - 10.0.0.255 for open proxies: scanssh -p 10.0.0.0/24 The next command scans for ssh servers on port 22 only: scanssh -n 22 -s ssh 192.168.0.0/16 The following command can be used in a parallel scan. Two hosts scan the specified networks randomly, where this is the first host: scanssh 'random(0,rsd)/split(1,2)/(192.168.0.0/16 10.1.0.0/24):22,80' BUGS
At the moment, scanssh leaves a one line entry in the log file of the ssh server. It is probably not possible to avoid that. BSD
