# SSH Connection Options for R630-04
|
|
|
|
**Last Updated:** 2026-01-31
|
|
**Document Version:** 1.0
|
|
**Status:** Active Documentation
|
|
|
|
**IP:** 192.168.11.14
|
|
**User:** root
|
|
**Issue:** Permission denied with password authentication.
|
|
|
|
---
|
|
|
|
## Possible Causes
|
|
|
|
1. **Password incorrect** - Double-check the password
|
|
2. **Password authentication disabled** - Server may require key-based auth
|
|
3. **Account locked** - Too many failed attempts
|
|
4. **SSH configuration** - Server may have restrictive settings
|
|
5. **Wrong user** - May need different username
|
|
|
|

|
|
|
|
## Troubleshooting Steps
|
|
|
|
### 1. Check SSH Authentication Methods
|
|
|
|
From another host that can connect to R630-04, check:
|
|
|
|
```bash
|
|
ssh -v root@192.168.11.14 2>&1 | grep -i "auth"
|
|
```
|
|
|
|
Look for:
|
|
- `publickey` - Key-based authentication enabled
|
|
- `password` - Password authentication enabled
|
|
- `keyboard-interactive` - Interactive password prompt
|
|
|
|
### 2. Try Different Authentication Methods
|
|
|
|
**Option A: Use SSH Key (if available)**
|
|
|
|
```bash
|
|
# Check for existing SSH keys
|
|
ls -la ~/.ssh/id_*
|
|
|
|
# Copy public key to R630-04 (if you have access from another host)
|
|
ssh-copy-id root@192.168.11.14
|
|
```
|
|
|
|
**Option B: Check if password has special characters**
|
|
|
|
The password `L@kers2010` contains `@` which should work, but try:
|
|
- Typing it carefully
|
|
- Using copy-paste
|
|
- Checking for hidden characters
|
|
|
|
### 3. Connect from R630-03 (which works)
|
|
|
|
Since R630-03 works, you can:
|
|
|
|
```bash
|
|
# SSH to R630-03 first
|
|
ssh root@192.168.11.13
|
|
# Password: L@kers2010
|
|
|
|
# Then from R630-03, SSH to R630-04
|
|
ssh root@192.168.11.14
|
|
```
|
|
|
|
### 4. Check SSH Configuration on R630-04
|
|
|
|
If you have console access or another way to access R630-04:
|
|
|
|
```bash
|
|
# Check SSH configuration
|
|
cat /etc/ssh/sshd_config | grep -E "PasswordAuthentication|PubkeyAuthentication|PermitRootLogin"
|
|
|
|
# Should show:
|
|
# PasswordAuthentication yes (or the line commented out)
|
|
# PubkeyAuthentication yes
|
|
# PermitRootLogin yes (or prohibit-password)
|
|
```
|
|
|
|
### 5. Reset Root Password (if you have console access)
|
|
|
|
If you have physical/console access:
|
|
|
|
```bash
|
|
# Boot into single user mode or recovery
|
|
# Then reset password:
|
|
passwd root
|
|
```
|
|
|
|
### 6. Check Account Status
|
|
|
|
```bash
|
|
# Check if root account is locked
|
|
passwd -S root
|
|
|
|
# Check failed login attempts
|
|
lastb | grep root | tail -20
|
|
```
|
|
|

|
|
|
|
## Alternative Access Methods
|
|
|
|
### 1. Use Proxmox Console
|
|
|
|
If R630-04 is managed by another Proxmox host:
|
|
|
|
```bash
|
|
# From Proxmox host managing R630-04
|
|
pct enter <container-id> # if it's a container
|
|
# or
|
|
qm monitor <vm-id> # if it's a VM
|
|
```
|
|
|
|
### 2. Use iDRAC/iLO (Dell R630)
|
|
|
|
If it's a physical Dell R630 server:
|
|
|
|
- Access iDRAC interface (usually https://<idrac-ip>)
|
|
- Use remote console
|
|
- Reset password from console
|
|
|
|
### 3. Network Boot/KVM Access
|
|
|
|
If you have KVM over IP or network boot access, you can:
|
|
- Access console directly
|
|
- Reset password
|
|
- Check SSH configuration
|
|
|

|
## Quick Verification
|
|
|
|
Try these commands from R630-03 (which works):
|
|
|
|
```bash
|
|
# From R630-03
|
|
ssh root@192.168.11.13
|
|
# After logging in, try:
|
|
ssh -v root@192.168.11.14 2>&1 | grep -E "auth|password|key"
|
|
```
|
|
|

|
|
|
|
## Recommended Next Steps
|
|
|
|
1. **Try connecting from R630-03** - Sometimes network path matters
|
|
2. **Verify password** - Try typing it again carefully
|
|
3. **Check if password was changed** - May have been changed since last login
|
|
4. **Use console access** - If available (iDRAC, KVM, etc.)
|
|
5. **Check SSH logs on R630-04** - `/var/log/auth.log` or `journalctl -u ssh`
|
|

## If Password Authentication is Disabled
|
|
|
|
If the server only accepts SSH keys:
|
|
|
|
1. **Generate SSH key pair** (on your local machine):
|
|
```bash
|
|
ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519_r630-04
|
|
```
|
|
|
|
2. **Copy public key** (if you have another way to access):
|
|
```bash
|
|
# Method 1: If you have access from R630-03
|
|
ssh root@192.168.11.13
|
|
ssh-copy-id -i ~/.ssh/id_ed25519_r630-04.pub root@192.168.11.14
|
|
|
|
# Method 2: Manual copy (if you have console access)
|
|
# Copy the public key content to:
|
|
# /root/.ssh/authorized_keys on R630-04
|
|
```
|
|
|
|
3. **Connect with key**:
|
|
```bash
|
|
ssh -i ~/.ssh/id_ed25519_r630-04 root@192.168.11.14
|
|
```
