We'll have to wait and see

a) The flaw has nothing to do with the kernel version (and therefore nothing to do with linus). It is in a commonly used user-space library.
b) The flaw has already been fixed by the major vendors. Updated versions of affected packages are available immediately from RedHat, Debian, Mandrake, etc.
c) RedHat != Linux. The next RedHat version will (probably) be 7.3. The next linux (kernel) version will be 2.4.19

vsftpd fatal flaw - can C help

I am not a C programmer, so I was hoping someone can help with the following: vsftpd is programmed in C, but it has a fatal flaw whereby uploads can be copied by Samba before the upload is complete (this includes the latest vsftpd daemon) This is because vsftpd does not support file locking, unlike...

How do I network a Suse installed machine with other computers, specifically Red hat Linux?

How do I network a Suse installed machine with other computers, specifically Red hat Linux? This is for a school project, and I can't find any pages that tell how to network a Suse to other computers except how to use a printer.

ipcs

IPCS(1) 						     Linux Programmer's Manual							   IPCS(1)

NAME

       ipcs - provide information on ipc facilities

SYNOPSIS

       ipcs [-asmq] [-tclup]
       ipcs [-smq] -i id
       ipcs -h

DESCRIPTION

       ipcs provides information on the ipc facilities for which the calling process has read access.

       The -i option allows a specific resource id to be specified.  Only information on this id will be printed.

       Resources may be specified as follows:

       -m     shared memory segments

       -q     message queues

       -s     semaphore arrays

       -a     all (this is the default)

       The output format may be specified as follows:

       -t     time

       -p     pid

       -c     creator

       -l     limits

       -u     summary

SEE ALSO

       ipcrm(1), ipcmk(1)

CONFORMING TO

       The  Linux  ipcs  utility is not fully compatible to the POSIX ipcs utility.  The Linux version does not support the -b and -o options, but
       does support the -l and -u options not defined by POSIX. The portable application shall not use the -a, -b, -o, -l, and -u options.
