| 335 | When the Installation CD boots, it tries to detect all your hardware devices |
|
|
| 336 | and loads the appropriate kernel modules to support your hardware. In the vast |
|
|
| 337 | majority of cases, it does a very good job. However, in some cases it may not |
|
|
| 338 | auto-load the kernel modules you need. If the PCI auto-detection missed some of |
|
|
| 339 | your system's hardware, you will have to load the appropriate kernel modules |
|
|
| 340 | manually. |

|
|
| 359 | If you are an advanced user, you might want to tweak the IDE hard disk |
|
|
| 360 | performance using <c>hdparm</c>. With the <c>-tT</c> options you can |
|
|
| 361 | test the performance of your disk (execute it several times to get a |
|
|
| 362 | more precise impression): |

|
| 367 | </pre> |
|
|
| 368 | |
|
|
| 369 | <p> |
|
|
| 370 | To tweak, you can use any of the following examples (or experiment |
|
|
| 371 | yourself) which use <path>/dev/hda</path> as disk (substitute with your |
|
|
| 372 | disk): |

| 389 | If you plan on giving other people access to your installation |
|
|
| 390 | environment or you want to chat using <c>irssi</c> without root privileges (for |
|
|
| 391 | security reasons), you need to create the necessary user accounts and change |
|
|
| 392 | the root password. |
|
|
| 393 | </p> |
|
|
| 394 | |
|

|
|
| 406 | To create a user account, we first enter their credentials, followed by |
|
|
| 407 | its password. We use <c>useradd</c> and <c>passwd</c> for these tasks. |
|
|
| 408 | In the next example, we create a user called "john". |

| 433 | <p> |
|
|
| 434 | If you want to allow other users to access your computer during the |
|
|
| 435 | Gentoo installation (perhaps because those users are going to help you |
|
|
| 436 | install Gentoo, or even do it for you), you need to create a user |
|
|
| 437 | account for them and perhaps even provide them with your root password |
|
|
| 438 | (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user). |
|
|
| 439 | </p> |
|
|
| 440 | |
|
|
| 441 | <p> |
|
|
| 442 | To fire up the SSH daemon, execute the following command: |
|
|
| 443 | </p> |
|
|
| 444 | |
|
|
| 445 | <pre caption="Starting the SSH daemon"> |

|
|

|
|
| 449 | <p> |
|
|
| 450 | To be able to use sshd, you first need to set up your networking. Continue with |
|
|
| 451 | the chapter on <uri link="?part=1&chap=3">Configuring your Network</uri>. |
