limits \- Festlegung von Resourcenbeschr\(:ankungen
.SH "BESCHREIBUNG"
.PP
The
\fIlimits\fR
file (/etc/limits
by default or LIMITS_FILE defined
config\&.h) describes the resource limits you wish to impose\&. It should be owned by root and readable by root account only\&.
.PP
Standardm\(:a\(ssig bestehen f\(:ur Root keine Einschr\(:ankungen\&. Tats\(:achlich gibt es keine M\(:oglichkeit, mit diesem Verfahren Root\-Konten (Konten mit der UID 0) Beschr\(:ankungen aufzuerlegen\&.
.PP
Jede Zeile beschreibt eine Beschr\(:ankung f\(:ur einen Benutzer in der Form:
.PP
\fIBenutzer BESCHR\(:ANKUNGSZEICHENKETTE\fR
.PP
oder in der Form:
.PP
\fI@Gruppe BESCHR\(:ANKUNGSZEICHENKETTE\fR
.PP
The
\fILIMITS_STRING\fR
is a string of a concatenated list of resource limits\&. Each limit consists of a letter identifier followed by a numerical limit\&.

For example,
\fIL2D2048N5\fR
is a valid
\fILIMITS_STRING\fR\&. For reading convenience, the following entries are equivalent:
.sp
.if n \{\
.RS 4
.\}
.nf
      username L2D2048N5
      username L2 D2048 N5
    
.fi
.if n \{\
.RE
.\}
.PP
Be aware that after
\fIusername\fR
the rest of the line is considered a limit string, thus comments are not allowed\&. An invalid limits string will be rejected (not considered) by the
\fBlogin\fR
program\&.
.PP
The default entry is denoted by username "\fI*\fR"\&. If you have multiple
\fIdefault\fR
entries in your
\fILIMITS_FILE\fR, then the last one will be used as the default entry\&.
.PP
The limits specified in the form "\fI@group\fR" apply to the members of the specified
\fIgroup\fR\&.
.PP
If more than one line with limits for a user exist, only the first line for this user will be considered\&.
.PP
If no lines are specified for a user, the last
\fI@group\fR
line matching a group whose the user is a member of will be considered, or the last line with default limits if no groups contain the user\&.
.PP
To completely disable limits for a user, a single dash "\fI\-\fR" will do\&.
.PP
To disable a limit for a user, a single dash "\fI\-\fR" can be used instead of the numerical value for this limit\&.
.PP
Ber\(:ucksichtigen Sie auch, dass alle Beschr\(:ankungen nur JE ANMELDUNG gelten\&. Sie sind nicht global und auch nicht dauerhaft\&. Vielleicht wird es einmal globale Beschr\(:ankungen geben, f\(:ur jetzt muss dies aber reichen ;)
