# Oracle PostgreSQL Authentication Fix Guide
2+
3+
## Problem
4+
PostgreSQL on Oracle instance is configured for **ident/peer** authentication, but Dependency-Check (running in Docker) needs **md5 password** authentication.
5+
6+
**Error**: `FATAL: Ident authentication failed for user "depcheck_scanner"`
7+
8+
## Solution Overview
9+
Update PostgreSQL configuration to allow password authentication for the `depcheck_scanner` user.
10+
11+
---
12+
13+
## Step-by-Step Fix
14+
15+
### Step 1: Connect to Oracle Instance
16+
17+
```bash
18+
ssh -i "/Users/alpinro/Code Prjects/codequal/keys/oracle/ssh-key-2025-05-08.key" opc@129.213.49.128
19+
```
20+
21+
---
22+
23+
### Step 2: Check Current PostgreSQL Configuration
24+
25+
```bash
26+
# Check current pg_hba.conf
27+
sudo cat /var/lib/pgsql/data/pg_hba.conf | grep -v "^#" | grep -v "^$"
28+
```
29+
30+
**Expected output** (problematic):
31+
```
32+
local all all peer
33+
host all all 127.0.0.1/32 ident
34+
host all all ::1/128 ident
35+
```
36+
37+
---
38+
39+
### Step 3: Backup Current Configuration
40+
41+
```bash
42+
# Create backup
43+
sudo cp /var/lib/pgsql/data/pg_hba.conf /var/lib/pgsql/data/pg_hba.conf.backup.$(date +%Y%m%d)
44+
45+
# Verify backup
46+
ls -lh /var/lib/pgsql/data/pg_hba.conf*
47+
```
48+
49+
---
50+
51+
### Step 4: Update pg_hba.conf
52+
53+
```bash
54+
# Edit pg_hba.conf with sudo
55+
sudo vi /var/lib/pgsql/data/pg_hba.conf
56+
```
57+
58+
**Find these lines:**
59+
```
60+
local all all peer
61+
host all all 127.0.0.1/32 ident
62+
host all all ::1/128 ident
63+
```
64+
65+
**Change to:**
66+
```
67+
local all all peer
68+
host all all 127.0.0.1/32 md5
69+
host all all ::1/128 md5
70+
host all all 0.0.0.0/0 md5
71+
```
72+
73+
**Or use this command** (automated):
74+
```bash
75+
# This will update the file automatically
76+
sudo bash -c 'cat > /var/lib/pgsql/data/pg_hba.conf << EOF
77+
# TYPE DATABASE USER ADDRESS METHOD
78+
79+
# "local" is for Unix domain socket connections only
80+
local all all peer
81+
82+
# IPv4 local connections - CHANGED FROM ident TO md5
83+
host all all 127.0.0.1/32 md5
84+
85+
# IPv6 local connections - CHANGED FROM ident TO md5
86+
host all all ::1/128 md5
87+
88+
# Allow Docker containers to connect - NEW LINE
89+
host all all 172.17.0.0/16 md5
90+
91+
# Allow all IPv4 connections (if needed for external access)
92+
# host all all 0.0.0.0/0 md5
93+
EOF'
94+
```
95+
96+
---
97+
98+
### Step 5: Reload PostgreSQL Configuration
99+
100+
```bash
101+
# Reload PostgreSQL to apply changes (no downtime)
102+
sudo systemctl reload postgresql
103+
104+
# Verify service is still running
105+
sudo systemctl status postgresql
106+
```
107+
108+
**Expected output:**
109+
```
110+
● postgresql.service - PostgreSQL database server
111+
Loaded: loaded
112+
Active: active (running)
113+
```
114+
115+
---
116+
117+
### Step 6: Test Database Connection
118+
119+
```bash
120+
# Test connection with password authentication
121+
PGPASSWORD=postgres123 psql -h localhost -U depcheck_scanner -d depcheck -c "SELECT COUNT(*) as cve_count FROM vulnerability;"
122+
```
123+
124+
**Expected output:**
125+
```
126+
cve_count
127+
-----------
128+
208247
129+
(1 row)
130+
```
131+
132+
If you see the CVE count, **authentication is working!** ✅
133+
134+
---
135+
136+
### Step 7: Test from Docker Container
137+
138+
```bash
139+
# Test that Docker containers can connect
140+
docker run --rm \
141+
-v /tmp/jdbc-drivers:/tmp/jdbc-drivers \
142+
iad.ocir.io/idzaw9ddo1h5/codequal/analyzer:lang-java-v6.0-arm \
143+
-c "psql 'jdbc:postgresql://host.docker.internal:5432/depcheck?user=depcheck_scanner&password=postgres123' -c 'SELECT 1;'"
144+
```
145+
146+
If this works, Docker connectivity is confirmed.
147+
148+
---
149+
150+
### Step 8: Verify OSS Index Integration
151+
152+
```bash
153+
# Run the OSS Index test
154+
cd /tmp
155+
curl -O https://raw.githubusercontent.com/your-repo/test-ossindex-oracle.sh
156+
chmod +x test-ossindex-oracle.sh
157+
./test-ossindex-oracle.sh
158+
```
159+
160+
---
161+
162+
## Troubleshooting
163+
164+
### Issue 1: Permission Denied
165+
166+
```bash
167+
# If you get "permission denied" when editing pg_hba.conf
168+
sudo chmod 644 /var/lib/pgsql/data/pg_hba.conf
169+
sudo vi /var/lib/pgsql/data/pg_hba.conf
170+
sudo chmod 600 /var/lib/pgsql/data/pg_hba.conf
171+
```
172+
173+
### Issue 2: PostgreSQL Won't Reload
174+
175+
```bash
176+
# Check logs
177+
sudo journalctl -u postgresql -n 50
178+
179+
# If reload fails, restart (brief downtime)
180+
sudo systemctl restart postgresql
181+
```
182+
183+
### Issue 3: Docker Can't Connect to Host
184+
185+
```bash
186+
# Add Docker network to pg_hba.conf
187+
sudo bash -c 'echo "host all all 172.17.0.0/16 md5" >> /var/lib/pgsql/data/pg_hba.conf'
188+
sudo systemctl reload postgresql
189+
```
190+
191+
### Issue 4: Check Docker Network
192+
193+
```bash
194+
# Find Docker bridge network
195+
docker network inspect bridge | grep Subnet
196+
197+
# Update pg_hba.conf with correct Docker subnet if different from 172.17.0.0/16
198+
```
199+
200+

201+
202+
## Verification Checklist
203+
204+
After completing the fix, verify:
205+
206+
- [ ] PostgreSQL is running: `sudo systemctl status postgresql`
207+
- [ ] Configuration updated: `sudo cat /var/lib/pgsql/data/pg_hba.conf | grep md5`
208+
- [ ] Local connection works: `PGPASSWORD=postgres123 psql -h localhost -U depcheck_scanner -d depcheck -c "SELECT 1;"`
209+
- [ ] Docker connection works: Test with dependency-check container
210+
- [ ] OSS Index test passes: Run test-ossindex-oracle.sh
211+
- [ ] No authentication errors in logs: `sudo journalctl -u postgresql -n 100 | grep -i "authentication failed"`
212+

214+
215+
## Quick Fix (Copy-Paste)
216+
217+
If you want to do it all in one go:
218+
219+
```bash
220+
# Connect to Oracle
221+
ssh -i "/Users/alpinro/Code Prjects/codequal/keys/oracle/ssh-key-2025-05-08.key" opc@129.213.49.128
222+
223+
# Backup and update pg_hba.conf
224+
sudo cp /var/lib/pgsql/data/pg_hba.conf /var/lib/pgsql/data/pg_hba.conf.backup
225+
sudo sed -i 's/ident$/md5/g' /var/lib/pgsql/data/pg_hba.conf
226+
sudo bash -c 'echo "host all all 172.17.0.0/16 md5" >> /var/lib/pgsql/data/pg_hba.conf'
227+
228+
# Reload PostgreSQL
229+
sudo systemctl reload postgresql
230+
231+
# Test connection
232+
PGPASSWORD=postgres123 psql -h localhost -U depcheck_scanner -d depcheck -c "SELECT COUNT(*) FROM vulnerability;"
233+
234+
# If you see a count, you're done! ✅
235+
```
236+
237+
---
238+
239+
## What This Fix Does
240+
241+
1. **Changes authentication method** from `ident` (system user verification) to `md5` (password-based)
242+
2. **Allows Docker containers** to connect to PostgreSQL (172.17.0.0/16 network)
243+
3. **Enables Dependency-Check** to use PostgreSQL database from within Docker
244+
4. **Enables OSS Index integration** to work properly
245+
246+
---
247+
248+
## Expected Results After Fix
249+
250+
✅ Dependency-Check can connect to PostgreSQL
251+
✅ OSS Index integration works
252+
✅ No "authentication failed" errors
253+
✅ All Java tools (PMD, Checkstyle, Dependency-Check, etc.) work correctly
254+
✅ CVE scanning completes successfully
255+
256+

257+
258+
## Need Help?
259+
260+
If you encounter any issues:
261+
262+
1. Check PostgreSQL logs: `sudo journalctl -u postgresql -f`
263+
2. Verify pg_hba.conf syntax: `sudo -u postgres psql -c "SELECT pg_reload_conf();"`
264+
3. Test connection manually: `PGPASSWORD=postgres123 psql -h localhost -U depcheck_scanner -d depcheck`
265+
266+
---
267+
268+
**Time to Complete**: ~5 minutes
269+
**Downtime**: None (using reload instead of restart)
270+
**Risk**: Low (backup created before changes)
