- Name server specification
- Introduction
-
- 11.. TTaasskkss
-
- You must specify a name server (its IP number). This is the missing
- link allowing your workstation to operate with machine names and
- translate those to IP numbers.
-
- You are allowed to specify up to three name servers. The second one is
- used if the first fail and so on. Note that if the first fail, you
- will get noticeable timeouts.
-
- You may also set a domain name here. This domain will be appended each
- time you do a name lookup. This saves you from giving the full name
- all the time.
-
- Search domains are like the default domain, but you are allowed to
- give six possibilities. Beware that search domain take control over
- the default domain. If you use this feature, you are defeating the
- default domain. It is seldom used and generate more traffic between
- your station and the DNS. This may be important if the DNS is far
- away.

- 22.. TToo DDNNSS oorr nnoott
-
- There are two alternative to the _D_N_S: //eettcc//hhoossttss and _N_I_S (Network
- Information System). //eettcc//hhoossttss may be use on simple network. You must
- manually synchronize all file on each machines of the network.
-
- _N_I_S is a good alternative. It goes further than the _D_N_S as it manages
- also user accounts and passwords. It can be use at the same time as
- the _D_N_S (See "search path for host name" in the "_N_e_t_w_o_r_k _c_o_n_f_i_g_u_r_a_t_o_r"
- menu.
-
- Given that _L_i_n_u_x_c_o_n_f does not manage NIS server yet, setting a _D_N_S on
- your network and pointing all machines to it is a good idea. This is
- also a good idea because one day or the other, you will hook your
- network to the Internet (using a firewall or not) and at this time,
- you will need to point to a _D_N_S server anyway. Yours will be just
- fine.

-
- Standalone machine will generally not use a _D_N_S, except if they get
- connect to a larger network once in a while. Even then, they may use a
- _D_N_S on this larger network.
-
- _L_i_n_u_x_c_o_n_f checks at different times (boot time for one) for _D_N_S
- connectivity. If the _D_N_S fails to answer after few seconds, _L_i_n_u_x_c_o_n_f
- will complain about it and offer you to skip network configuration: A
- bad _D_N_S configuration or a faulty one are real show stoppers (It often
- gives the impression the computer is hung).
-
- This test is a saver, except if the machine does not have full time
- access to a DNS. The check box is just there to tell _L_i_n_u_x_c_o_n_f not to
- care that much about the _D_N_S. It won't change the operation of the
- machine beside that.
- 33..22.. DDeeffaauulltt ddoommaaiinn
-
- You generally enter here the domain you use most, generally the domain
- of your organisation.
-
- 33..33.. NNaammeesseerrvveerr 11 22 aanndd 33
-
- You must enter an IP number, not a machine name. For a standalone
- which never connect to any larger network, this is optionnal.

-
- An alternative to the default domain are the "Search domain" fields.
- While this add some overhead to _D_N_S search, it may be a good time
- saver if you talk regularly to several machines spreaded in different
- domain.
-
- Note that using "Search domains" is exclusive to the "default domain"
- field. Use one or the others.
