The configure script will abort if your compiler is not ANSI compliant. If this happens, use the GNU C compiler, available via anonymous ftp: ftp://prep.ai.mit.edu/pub/gnu/gcc.tar.gz If necessary, edit the BINDEST and MANDEST paths in Makefile.in and run ./configure (a shell script). "configure" will determine your system attributes and generate an appropriate Makefile from Makefile.in. Now build nslint by running "make". If everything builds ok, su and type "make install" (and optionally "make install-man). This will install nslint and its manual entry. If your system is not one which we have tested nslint on, you may have to modify the configure script and Makefile.in. Please send us patches for any modifications you need to make.

If any problems are discovered, error messages are displayed on .I stderr and .B nslint exits with a non-zero status. .LP Here is a partial list of errors .B nslint detects: .IP Records that are malformed. .IP Names that contain dots but are missing a trailing dot. .IP .B PTR records with names that are missing a trailing dot. .IP Names that contain illegal characters (rfc1034). .IP .B A records without matching .B PTR records .IP .B PTR records without matching .B A records .IP Names with more than one address on the same subnet. .IP Addresses in use by more than one name. .IP Names with .B CNAME and other records (rfc1033). .IP Unknown service and/or protocol keywords in .B WKS records. .IP Missing semicolons and quotes. .LP .SH OPTIONS .TP .B -b Specify an alternate .I named.boot file. The default is .IR /etc/named.boot . .TP .TP .B -c Specify an alternate .I named.conf file. The default is .IR /etc/named.conf . .TP .B -B Specify an alternate .I nslint.boot file. The default is .I nslint.boot in the last .B directory line processed in .I named.boot (or the current working directory). This file is processed like a second .IR named.boot . The most common use is to tell .B nslint about .B A records that match .B PTR records that point outside the domains listed in .IR named.boot . .TP .B -C Specify an alternate .I nslint.conf file. The default is .I nslint.conf in the last .B directory line processed in .I named.conf (or the current working directory). This file is processed like a second .IR named.conf . .TP .B -d Raise the debugging level. Debugging information is displayed on .IR stdout . .LP .B Nslint knows how to read BIND 8 and 9's .I named.conf configuration file and also older BIND's .I named.boot file. If both files exist, .B nslint will prefer .I named.conf (on the theory that you forgot to delete .I named.boot when you upgraded BIND). .LP .SH "ADVANCED CONFIGURATION" There are some cases where it is necessary to use the advanced configuration features of .BR nslint . Advanced configuration is done with the .I nslint.conf file. (You can also use .I nslint.boot which has a syntax similar to .I named.boot but is not described here.) .LP The most common is when a site has a demilitarized zone (DMZ). The problem here is that the DMZ network will have .B PTR records for hosts outside its domain. For example lets say we have .I 128.0.rev with: .LP .RS .nf .sp .5 1.1 604800 in ptr gateway.lbl.gov. 2.1 604800 in ptr gateway.es.net. .sp .5 .fi .RE .LP Obviously we will define an .B A record for .I gateway.lbl.gov pointing to .I 128.0.1.1 but we will get errors because there is no .B A record defined for .IR gateway.es.net . The solution is to create a .I nslint.conf file (in the same directory as the other dns files) with: .LP .RS .nf .sp .5 zone "es.net" { .RS type master; file "nslint.es.net"; .RE }; .sp .5 .fi .RE .LP And then create the file .I nslint.es.net with: .LP .RS .nf .sp .5 gateway 1 in a 128.0.1.2 .sp .5 .fi .RE .LP Another problem occurs when there is a .B CNAME that points to a host outside the local domains. Let's say we have .I info.lbl.gov pointing to .IR larry.es.net : .LP .RS .nf .sp .5 info 604800 in cname larry.es.net. .sp .5 .fi .RE .LP In this case we would need: .LP .RS .nf .sp .5 zone "es.net" { .RS type master; file "nslint.es.net"; .RE }; .sp .5 .fi .RE .LP in .I nslint.boot and: .LP .RS .nf .sp .5 larry 1 in txt "place holder" .sp .5 .fi .RE .LP .IR nslint.es.net . .LP One last problem when a pseudo host is setup to allow two more more actual hosts provide a service. For, let's say that .I lbl.gov contains: .LP .RS .nf .sp .5 server 604800 in a 128.0.6.6 server 604800 in a 128.0.6.94 ; tom 604800 in a 128.0.6.6 tom 604800 in mx 0 lbl.gov. ; jerry 604800 in a 128.0.6.94 jerry 604800 in mx 0 lbl.gov. .sp .5 .fi .RE .LP In this case .B nslint would complain about missing .B PTR records and ip addresses in use by more than one host. To suppress these warnings, add you would the lines: .LP .RS .nf .sp .5 zone "lbl.gov" { .RS type master; file "nslint.lbl.gov"; .RE }; .LP zone "0.128.in-addr.arpa" { .RS type master; file "nslint.128.0.rev"; .RE }; .sp .5 .fi .RE .LP to .I nslint.conf and create .I nslint.lbl.gov with: .LP .RS .nf .sp .5 server 1 in allowdupa 128.0.6.6 server 1 in allowdupa 128.0.6.94 .sp .5 .fi .RE .LP and create .I nslint.128.0.rev with: .LP .RS .nf .sp .5 6.6 604800 in ptr server.lbl.gov. 94.6 604800 in ptr server.lbl.gov. .sp .5 .fi .RE .LP In this example, the .B allowdupa keyword tells .B nslint that it's ok for .I 128.0.6.6 and .I 128.0.6.94 to be shared by .IR server.lbl.gov , .IR tom.lbl.gov , and .IR jerry.lbl.gov . .LP Another .B nslint feature helps detect hosts that have mistakenly had two ip addresses assigned on the same subnet. This can happen when two different people request an ip address for the same hostname or when someone forgets an address has been assigned and requests a new number. .LP To detect such .B A records, add a .B nslint section to your .I nslint.conf containing something similar to: .LP .RS .nf .sp .5 nslint { .RS network "128.0.6/22"; .RE }; .sp .5 .fi .RE .LP or: .LP .RS .nf .sp .5 nslint { .RS network "128.0.6 255.255.252.0"; .RE }; .sp .5 .fi .RE .LP These two examples are are equivalent ways of saying the same thing; that subnet .I 128.0.6 has a 22 bit wide subnet mask. .LP Using information from the above .B network statement, .B nslint would would flag the following .B A records as being in error: .LP .RS .nf .sp .5 server 1 in a 128.0.6.48 server 1 in a 128.0.7.16 .sp .5 .fi .RE .LP Note that if you specify any .B network lines in your .I nslint.conf file, .B nslint requires you to include lines for all networks; otherwise you might forget to add .B network lines for new networks. .LP Sometimes you have a zone that .B nslint just can't deal with. A good example is a dynamic dns zone. To handle this, you can add the following to .IB nslint.com : .LP .RS .nf .sp .5 nslint { .RS ignorezone "dhcp.lbl.gov"; .RE }; .sp .5 .fi .RE .LP This will suppress "name referenced without other records" warnings. .LP .SH FILES .na .nh .nf /etc/named.conf - default named configuration file /etc/named.boot - old style named configuration file nslint.conf - default nslint configuration file nslint.boot - old style nslint configuration file .ad .hy .fi .LP .SH "SEE ALSO" .na .nh .IR named (8), rfc1033, rfc1034 .ad .hy .SH AUTHOR Craig Leres of the Lawrence Berkeley National Laboratory, University of California, Berkeley, CA. .LP The current version is available via anonymous ftp: .LP .RS .I ftp://ftp.ee.lbl.gov/nslint.tar.gz .RE .SH BUGS Please send bug reports to nslint@ee.lbl.gov. .LP Not everyone is guaranteed to agree with all the checks done. nslint-3.2/nslint.c000644 001774 000034 00000176411 14560523006 014316 0ustar00leressrc000000 000000 /* * Copyright (c) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2005, 2006, 2007, 2008, 2009, 2010 * The Regents of the University of California.
