Security Newsletter
Bruce Schneier has released a special edition of his monthly Crypto-Gram security newsletter. This issue discusses security & technology topics relating to the September 11th attack. It is not strictly Unix related, but I think it is well worth the read as it contains a lot of well-though out, interesting information.
Recommended reading for anyone interested in techology. (it is long: approx 18 pages)

Those of you in the US, if nothing else read the last section entitled "How to Help". A quote from the article:

"We have less than 100 hours before Congress acts on legislation that will (a) significantly expand the use of Carnivore, (b) make computer hacking a form of terrorism, (c) expand electronic surveillance in routine criminal investigations, and (d) reduce government accountability."

Check it out, and post your comments here.

list_devices(1)                                                                                                                    list_devices(1)

NAME

       list_devices - list allocatable devices

SYNOPSIS

       list_devices [-s] [ -U uid] -l [device]

       list_devices [-s] [ -U uid] -n [device]

       list_devices [-s] [ -U uid] -u [device]

       The list_devices utility lists the allocatable devices in the system according to specified qualifications.

       The  device  and all device special files associated with the device are listed. The device argument is optional and, if it is not present,
       all relevant devices are listed.

       The following options are supported:

       -l [device]     Lists the pathname(s) of the device special files associated with the device that are allocatable to the  current  process.
                       If device is given, lists only the files associated with the specified device.

       -n [device]     Lists  the  pathname(s)  of device special files associated with the device that are allocatable to the current process but
                       are not currently allocated. If device is given, lists only the files associated with that device.

       -s              Silent. Suppresses any diagnostic output.

       -u [device]     Lists the pathname(s) of device special files, associated with the device that are allocated to the owner  of  the  current
                       process. If device is given, list only the files associated with that device.

       -U uid          Uses the user ID uid instead of the real user ID of the current process when performing the list_devices operation.  Only a
                       user with the solaris.device.revoke authorization can use this option.

       The following exit values are returned:

       non--zero       An error occurred.
