# 113 - Pentesting Ident

{{#include ../banners/hacktricks-training.md}}

## Basic Information

**Ident Protocol** inatumika juu ya **Internet** kuhusisha **TCP connection** na mtumiaji maalum. Ilipangwa awali kusaidia katika **network management** na **security**, inafanya kazi kwa kuruhusu server kuuliza client kwenye port 113 ili kutafuta taarifa kuhusu mtumiaji wa **TCP connection** fulani.

Hata hivyo, kutokana na wasiwasi wa kisasa kuhusu faragha na uwezekano wa matumizi mabaya, matumizi yake yamepungua kwani yanaweza bila kukusudia kufichua taarifa za mtumiaji kwa wahusika wasioidhinishwa. Hatua za usalama zilizoboreshwa, kama vile muunganisho wa siri na udhibiti mkali wa ufikiaji, zinapendekezwa kupunguza hatari hizi.

**Default port:** 113
```
PORT    STATE SERVICE
113/tcp open  ident
```
## **Uchunguzi**

### **Mkononi - Pata mtumiaji/Baini huduma**

Ikiwa mashine inafanya kazi na huduma ident na samba (445) na umeunganishwa na samba ukitumia bandari 43218. Unaweza kupata ni mtumiaji gani anayeendesha huduma ya samba kwa kufanya:

![](<../images/image (843).png>)

Ikiwa unabonyeza tu enter unapounganisha na huduma:

![](<../images/image (159).png>)

Makosa mengine:

![](<../images/image (359).png>)

### Nmap

Kwa kawaida (\`-sC\`\`) nmap itabaini kila mtumiaji wa kila bandari inayofanya kazi:
```
PORT    STATE SERVICE     VERSION
22/tcp  open  ssh         OpenSSH 4.3p2 Debian 9 (protocol 2.0)
|_auth-owners: root
| ssh-hostkey:
|   1024 88:23:98:0d:9d:8a:20:59:35:b8:14:12:14:d5:d0:44 (DSA)
|_  2048 6b:5d:04:71:76:78:56:96:56:92:a8:02:30:73:ee:fa (RSA)
113/tcp open  ident
|_auth-owners: identd
139/tcp open  netbios-ssn Samba smbd 3.X - 4.X (workgroup: LOCAL)
|_auth-owners: root
445/tcp open  netbios-ssn Samba smbd 3.0.24 (workgroup: LOCAL)
|_auth-owners: root
```
### Ident-user-enum

[**Ident-user-enum**](https://github.com/pentestmonkey/ident-user-enum) ni script rahisi ya PERL ya kuuliza huduma ya ident (113/TCP) ili kubaini mmiliki wa mchakato unaosikiliza kwenye kila bandari ya TCP ya mfumo wa lengo. Orodha ya majina ya watumiaji iliyokusanywa inaweza kutumika kwa mashambulizi ya kukisia nywila kwenye huduma nyingine za mtandao. Inaweza kusakinishwa kwa `apt install ident-user-enum`.
```
root@kali:/opt/local/recon/192.168.1.100# ident-user-enum 192.168.1.100 22 113 139 445
ident-user-enum v1.0 ( http://pentestmonkey.net/tools/ident-user-enum )

192.168.1.100:22  root
192.168.1.100:113 identd
192.168.1.100:139 root
192.168.1.100:445 root
```

Entry_1:
Name: Notes
Description: Notes for Ident
Note: |
The Ident Protocol is used over the Internet to associate a TCP connection with a specific user. Originally designed to aid in network management and security, it operates by allowing a server to query a client on port 113 to request information about the user of a particular TCP connection.
