Server Penetration (Ubuntu

Hi,

I need help with penetrating a Ubuntu Server and I am kinda new in this, so I would need help!

Here are some information about the server.

TCP Sequence Prediction: Difficulty=255.

IP ID Sequence Generation: All zeros.

Service Info: OS: Linux; CPE: cpe:/o:linux:linux_kernel.

22/tcp open ssh OpenSSH 7.2p2 Ubuntu 4ubuntu2.2 (Ubuntu Linux; protocol 2.0).

| ssh-hostkey:

| 2048 60:61:e8:78:e7:55:60:d3:49:bd:06:40:81:6f:c5:19 (RSA)

| 256 ac:7d:da:49:90:97:99:17:e8:4e:97:71:f4:c3:cd:e7 (ECDSA)

|_ 256 08:96:7e:bb:51:ac:89:ab:81:68:f1:f7:19:26:13:24 (EdDSA)

25/tcp filtered smtp

111/tcp filtered rpcbind

135/tcp filtered msrpc

136/tcp filtered profile

137/tcp filtered netbios-ns

138/tcp filtered netbios-dgm

139/tcp filtered netbios-ssn

445/tcp filtered microsoft-ds

19132/tcp open unknown

44084/tcp open fmproduct 1-4 (RPC #1073741824)

Port 22, 19132 and 44084 are open. The others seems to be close.

Here is the IP of the machine : 207.246.122.247.vultr.com (207.246.122.247)

This is a simple scan, I don't know how to get more informations about the server. If someone can help.

Basically, I don't want to have access to commands or anything else, I need to have access to the files. Thank you.
