Aug 12, 2010We have a large number of devices on our LAN with the mac prefix of 00:60:60. We want to assign these addresses from a separate address pool. I've created two classes, one to match 00:60:60 and another that I want to contain any other device. When i try to start the server I get:
/etc/dhcp3/dhcpd.conf line 33: boolean expression expected
match if not binary-to-ascii(16,8,":",substring(hardware, 1, 3))
^#this carrot should be under the last parenthesis#
Configuration file errors encountered -- exiting
Here is the relevant section of /etc/dhcp3/dhcpd.conf
class "006060" {
match if binary-to-ascii(16,8,":",substring(hardware, 1, 3)) = "00:60:60";
}
[Code].....
I've tried a few variations on that line. I've spent days trying to find any examples of "match if not" and haven't found anything. I assume it's going to be something to do with parenthesis/quote placement. Oh and this is ISC DHCP Server V3.0.4.
Server :: Allow Wireless Clients Access To Network Based On Their MAC Address?
Jan 11, 2011Using CentOS 5.5, FreeRADIUS 2.1.7.
Objective is simply to be able to allow wireless clients access to my network based on their MAC address (I have about 10 WAPs around the country which I need to be able to manage user access centrally). Not interested in LDAP or dishing out keys/certificates etc.
I have been trying to follow the guide here. Sounds like it's exactly what I need but I'm not sure about a few things.
1) For each of the conf files am I supposed to be replacing everything currently existing in the respective file with what is suggested?
2) "raddb/modules/file" does not exist, so I assume I should use "raddb/modules/files"?
3) If I uncomment the line:
Code:
#rewrite_calling_station_id
under the "raddb/sites-available/default authorize{}" section, the radiusd startup gives me the following error:
/etc/raddb/sites-enabled/default[69]: Failed to find module "rewrite_calling_station_id".
If anyone familiar with FreeRADIUS 2 could answer these queries I might be on the right path
Security :: IPTABLES - Restrict Internet Access Based On Time Of Day And MAC Address
Feb 6, 2010I am trying to configure my Linux router to restrict Internet access for one computer on my LAN. It needs to be restrictive based on the time of day and the days of the week. I am using the MAC address of the computer to single out the one computer that needs to be blocked. However, this is my first attempt at making any rules with iptables, and I am not sure if I am doing this right. If some one can take a look at this I would greatly appreciate it. This is what I have done so far.
Here is my thinking. Create a new target. Check the MAC address, if it is NOT the offending computer return to the default chain. If it is the offending computer check that we are between the allowed hours and dates and ACCEPT. If we are not within the time/date range then drop the packet.
Code:
Here I am trying to route all packets regardless of the computer on the LAN into the blocked_access chain for checking.
Code:
Is it a good idea to route all traffic through the blocked_access chain? I do run other servers that are accessible from the Internet, so I am not sure how this setup will affect that. I also use shorewall on the router to setup iptables for me. How would I integrate this with shorewall?
I am using squid to block access when he is using the web browser. However, he is still able to play games(World of Warcraft) and the like.
I am using Debian sid, iptable(1.4.6), shorewall(4.4.6), kernel 2.6.32-trunk-686.

View 6 Replies View RelatedGeneral :: How To Find Out What Your Distro Is Based On
Nov 28, 2010I have been using Linux for quite a while and have gotten pretty good at it, but recently I started using Backtrack in a VM and realized I have no idea what it is based on. Then I got to thinking I have no idea what that even means. For example, OSX is based on Darwin right, but what does that mean? Ubuntu is another that is based on Debian, but I don't know what that means.
The reason I'm asking is because in order to get my screen resolution and networking right in Backtrack I need to know what it is based on so I can download the proper packages to install the VirtualBox guest additions, and I have no idea. Is there a way to get this information from the operating system? Maybe uname -a is giving me the info and I just don't know where to look in the output?
Ubuntu :: Find Log Files And Delete Them Based On Age?
Aug 18, 2011I want find a bunch of log files and delete ones that are older than say 5 days. Ideally I would then like to add this my crontab to run once a day.
The log files are in /var/log and are owned by root. They have a standard naming convention which is [date]RootCronRsync-backupHOME.log An example file is 20100621RootCronRsync-backupHOME.log Trying to put together a bash script to do this I think I need something like
Code: find /var/log/ -name *RootCronRsync-backupHOME.log -mtime +5 -exec rm {} ; However if I try this without the -exec rm (ie to see if I can find the right files first) I get the following error find: paths must precede expression: 20090405RootCronRsync-backupHOME.log Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]
Fedora :: Terminal-based Programs Won't Run Because It Can't Find Libtermcap
May 30, 2010I installed Fedora 12 on a new machine (Intel Core i3) and one of my terminal-based programs won't run because it can't find libtermcap. The specific error is
Quote:
error while loading shared libraries: libtermcap.so.2: cannot open shared object file: No such file or directory
I seem to have this problem every other time I install a new Fedora. I tried a few things with old libtermcap files from other machines, and I tried looking around the YUM repository, but nothing seemed to work.
What's the proper way to get the libtermcap libraries for a Fedora 12 machine on an iCore i3?
General :: Finding Files Based On Date Without Using `find`?
Aug 11, 2011I know find can do what I am looking for, but I am wondering if there is an alternative way to find files on the filesystem either created before/after a certain point, or at a certain time.
Typically I rely on updatedb & locate for most of my file searching needs. Issues with those tools, though, are that it only has directory and file names, and it only creates a database of local directories, not anything mounted via CIFS|NFS or via -o loop (eg, .iso images).
So if I need to find files created after yesterday across the entire system (local and remote filesystems), I am currently needing to use find.
What other tools, if any, would accomplish this in a similar fashion?
I have tried ls and grep, but that requires (in my attempts so far) multiple searches:
ls -lR | grep Aug | grep 10
ls -lR | grep Aug | grep 11
