NCSA server directives

The following directives are only recognized in the NCSA server configuration file:

ServerType { inetd  | standalone }              (standalone)

The method by which the server is invoked. If the server is run from the inetd program you should specify:

    ServerType      inetd

There is no direct CERN equivalent. The CERN server determines its mode by the presence or absence of the Port directive.

ServerName name                   (determined automatically)

The host-name of the computer system on which the server is running. Usually this directive is not necessary as the server can find out the host-name by making a system call.

    ServerName      www.organization.domain

Equivalent to the CERN HostName directive.

Port portno                                             (80)

The port number on which the server should listen for requests.

    Port            8080

Equivalent to the CERN Port directive.

ServerRoot dir-name                   (/usr/local/etc/httpd)

The path of the directory in which the server should look for subdirectories containing configuration and log files.

    ServerRoot    /usr/local/etc/ncsa_httpd

.

Note that this is not the same as the CERN ServerRoot directive.

PidFile filename                 (ServerRoot/logs/httpd.pid)

The name of the file to which the server logs its process ID. The filename can be either an absolute path or relative to the ServerRoot directory.

    PidFile /tmp/ncsa_httpd.pid

Equivalent to the CERN PidFile directive.

TimeOut secs               (1,200 seconds, i.e. 20 minutes)

The time allowed for a client to send a request after an incoming connection is accepted and for the information to be accepted by the client.

    TimeOut 600

Equivalent to the CERN InputTimeout, OutputTimeout and ScriptTimeout directives.

User { user-name  | #userid }                          (#-1)

The login name, or numeric user ID preceded by a hash sign, under which the server will answer requests.

    User            #-2

Equivalent to the CERN UserID directive.

Group { group-name  | #group-id }                      (#-1)

The group name (from the /etc/group file), or numeric group ID preceded by a hash sign, under which the server will answer requests.

    Group WWW

Equivalent to the CERN GroupID directive.

ServerAdmin name                                (no default)

An electronic mail contact address included in error responses.

    ServerAdmin     [email protected]

There is no equivalent CERN directive.

IdentityCheck { on  | off }                            (off)

If enabled the server will contact the ident daemon on the system from which the request originated to determine the user name associated with the process issuing the request. This information is then included in log messages. The information cannot be relied upon as being valid: many systems do not run an ident daemon and obtaining the information consumes resources, so it is generally recommended that this option be left disabled.
Equivalent to the CERN IdentityCheck directive.

AccessConfig file              (ServerRoot/conf/access.conf)

The filename of the access configuration file. The filename can be either an absolute path or relative to the ServerRoot directory.
There is no equivalent CERN directive.

ResourceConfig file               (ServerRoot/conf/srm.conf)

The filename of the resource configuration file. The filename can be either an absolute path or relative to the ServerRoot directory.
There is no equivalent CERN directive.

TypesConfig file                (ServerRoot/conf/mime.types)

The filename of the types configuration file. The filename can be either an absolute path or relative to the ServerRoot directory.
prespace There is no equivalent CERN directive.

The following directive is a resource configuration directive and is only recognized in the resource configuration file.

DocumentRoot dir                      (/usr/local/etc/httpd)

The absolute path of the directory that the server uses as the root of the data hierarchy.

    DocumentRoot    /usr/public/www

Equivalent to the CERN ServerRoot directive.
