✍️ Type  -2 --> smtp-user-enum

smtp-user-enum
smtp-user-enum is a tool for enumerating OS-level user accounts on Solaris via the SMTP service (sendmail). Enumeration is performed by inspecting the responses to VRFY, EXPN, and RCPT TO commands. It could be adapted to work against other vulnerable SMTP daemons, but this hasn’t been done as of v1.0.

smtp-user-enum -M VRFY -U <user pwd dictionary> -t <ip>

 You can use default wordlist -->
/opt/metasploit/apps/pro/vendor/bundle/ruby/2.6.0/gems/metasploit-framework-4.17.75/data/wordlists/unix_users.txt

 You can varify user id if it exist.



✍️ Type  -3 --> Telnet using 25 port 

telnet <ip address> <25>
ex 
✍️ Type  -3 --> ismtp

exploit rpcbind

                            exploit rpcbind with nfs What is nfs?     Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems in 1984,allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The Network File System is an open standard defined in RFCs, allowing anyone to implement the protocol. What is rpcbind?     The rpcbind utility maps RPC services to the ports on which they listen. RPC processes notify rpcbind when they start, registering the ports they are listening on and the RPC program numbers they expect to serve. The client system then contacts rpcbind on the server with a particular RPC program number. The rpcbind service redirects the client to the proper port number so it can communicate with the requested service. Because RPC-based services

Exploit and connect to port 512 ,513, and 514

               Exploit and connect to port 512 ,513, and 514 ༄ Unix Basics      TCP ports 512, 513, and 514 are known as "r" services, and have been misconfigured       to allow remote access from any host (a standard ".rhosts + +" situation).       To take advantage of this, make sure the "rsh-client" client is installed (on Ubuntu), and      run the following command as your local root user. If you are prompted for an SSH key,      this means the rsh-client tools have not been installed and Ubuntu is defaulting to       using  SSH. 🔂 Step-1:               First type "nmap -v <victim ip>" 🔄 Step-2:               type "rlogin  -l <user account> <ip address of victim>                                                                          by Er.
