1	# SSH Skill
2
3	Use SSH for secure remote access, file transfers, and tunneling.
4
5	## Basic Connection
6
7	Connect to server:
8	```bash
9	ssh user@hostname
10	```
11
12	Connect on specific port:
13	```bash
14	ssh -p 2222 user@hostname
15	```
16
17	Connect with specific identity:
18	```bash
19	ssh -i ~/.ssh/my_key user@hostname
20	```
21
22	## SSH Config
23
24	Config file location:
25	```
26	~/.ssh/config
27	```
28
29	Example config entry:
30	```
31	Host myserver
32	HostName 192.168.1.100
33	User deploy
34	Port 22
35	IdentityFile ~/.ssh/myserver_key
36	ForwardAgent yes
37	```
38
39	Then connect with just:
40	```bash
41	ssh myserver
42	```
43
44	## Running Remote Commands
45
46	Execute single command:
47	```bash
48	ssh user@host "ls -la /var/log"
49	```
50
51	Execute multiple commands:
52	```bash
53	ssh user@host "cd /app && git pull && pm2 restart all"
54	```
55
56	Run with pseudo-terminal (for interactive):
57	```bash
58	ssh -t user@host "htop"
59	```
60
61	## File Transfer with SCP
62
63	Copy file to remote:
64	```bash
65	scp local.txt user@host:/remote/path/
66	```
67
68	Copy file from remote:
69	```bash
70	scp user@host:/remote/file.txt ./local/
71	```
72
73	Copy directory recursively:
74	```bash
75	scp -r ./local_dir user@host:/remote/path/
76	```
77
78	## File Transfer with rsync (preferred)
79
80	Sync directory to remote:
81	```bash
82	rsync -avz ./local/ user@host:/remote/path/
83	```
84
85	Sync from remote:
86	```bash
87	rsync -avz user@host:/remote/path/ ./local/
88	```
89
90	With progress and compression:
91	```bash
92	rsync -avzP ./local/ user@host:/remote/path/
93	```
94
95	Dry run first:
96	```bash
97	rsync -avzn ./local/ user@host:/remote/path/
98	```
99
100	## Port Forwarding (Tunnels)
101
102	Local forward (access remote service locally):
103	```bash
104	ssh -L 8080:localhost:80 user@host
105	# Now localhost:8080 connects to host's port 80
106	```
107
108	Local forward to another host:
109	```bash
110	ssh -L 5432:db-server:5432 user@jumphost
111	# Access db-server:5432 via localhost:5432
112	```
113
114	Remote forward (expose local service to remote):
115	```bash
116	ssh -R 9000:localhost:3000 user@host
117	# Remote's port 9000 connects to your local 3000
118	```
119
120	Dynamic SOCKS proxy:
121	```bash
122	ssh -D 1080 user@host
123	# Use localhost:1080 as SOCKS5 proxy
124	```
125
126	## Jump Hosts / Bastion
127
128	Connect through jump host:
129	```bash
130	ssh -J jumphost user@internal-server
131	```
132
133	Multiple jumps:
134	```bash
135	ssh -J jump1,jump2 user@internal-server
136	```
137
138	In config file:
139	```
140	Host internal
141	HostName 10.0.0.50
142	User deploy
143	ProxyJump bastion
144	```
145
146	## Key Management
147
148	Generate new key (Ed25519, recommended):
149	```bash
150	ssh-keygen -t ed25519 -C "your_email@example.com"
151	```
152
153	Generate RSA key (legacy compatibility):
154	```bash
155	ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
156	```
157
158	Copy public key to server:
159	```bash
160	ssh-copy-id user@host
161	```
162
163	Copy specific key:
164	```bash
165	ssh-copy-id -i ~/.ssh/mykey.pub user@host
166	```
167
168	## SSH Agent
169
170	Start agent:
171	```bash
172	eval "$(ssh-agent -s)"
173	```
174
175	Add key to agent:
176	```bash
177	ssh-add ~/.ssh/id_ed25519
178	```
179
180	Add with macOS keychain:
181	```bash
182	ssh-add --apple-use-keychain ~/.ssh/id_ed25519
183	```
184
185	List loaded keys:
186	```bash
187	ssh-add -l
188	```
189
190	## Multiplexing (Connection Sharing)
191
192	In ~/.ssh/config:
193	```
194	Host *
195	ControlMaster auto
196	ControlPath ~/.ssh/sockets/%r@%h-%p
197	ControlPersist 600
198	```
199
200	Create socket directory:
201	```bash
202	mkdir -p ~/.ssh/sockets
203	```
204
205	## Known Hosts
206
207	Remove old host key:
208	```bash
209	ssh-keygen -R hostname
210	```
211
212	Scan and add host key:
213	```bash
214	ssh-keyscan hostname >> ~/.ssh/known_hosts
215	```
216
217	## Debugging
218
219	Verbose output:
220	```bash
221	ssh -v user@host
222	```
223
224	Very verbose:
225	```bash
226	ssh -vv user@host
227	```
228
229	Maximum verbosity:
230	```bash
231	ssh -vvv user@host
232	```
233
234	## Security Tips
235
236	- Use Ed25519 keys (faster, more secure than RSA)
237	- Set `PasswordAuthentication no` on servers
238	- Use `fail2ban` on servers to block brute force
239	- Keep keys encrypted with passphrases
240	- Use `ssh-agent` to avoid typing passphrase repeatedly
241	- Restrict key usage with `command=` in authorized_keys
