Hi, Assume you are in hostile environment, as in you can't trust the DHCP serversss nor the TFTP/HTTP server. So you would want a checksum on kernel and initrd. Which checksum algoritme is available in pxelinux.0? Which checksum algoritme could be integrate into pxelinux.0? In other words: Please advice what could be done to verify what pxelinux.0 did download. Cheers Geert Stappers --

Hi I wrote a function implementing an algoritm for simulation of spatial sampling plans (using geoR). I'm using a range of parameters to perform several simulation and sometimes this parameters create function errors wich cause the algoritm to stop. How can I avoid this ? Below there's a small example that I made to study the problem but I was not able to solve it. I've tried

Hi there, I'm the process of centralizing user authentication for a medium-sized network with a few Linux servers, some of them runnng samba. The idea is migrating all user definitions from both /etc/{passwd,shadow,groups} and samba tdb to a central LDAP directory. Most servers had the same set of users, but as each one was administered in isolation (no NIS not all samba servers were part of

This was exactracted from a 8192x4 texture, with 32x4 tiles. 4 patterns appears, each 8x128 bytes long. these patterns are repeated, and one is always left out. So 123, 234, 134, 124. The repetetive cycle is therefore 4x3x8x128 = 12288 bytes long. I've included the color code ods file, which contains the normal -> actual position. I have no idea how this goes for larger tiles (is the

HI all, efficiency question for VERY low bandwith networks Suppose I know the list of files that are changed What is the most efficient way to make rsync sync this list. Currently I use --include-from --exclude to generate a 'filelist' but I suspect that client and/or server exchange the list of files in the module to be synced. this traffic can be avoided since the include-from

Hello there! I'm creacting a loop for(i in 1:n){...}within which I build a nls model at each iteration. for some of the values of i, the algoritm in the nls function doesn't converge or cannot find a solution and consequently an error message is produced, and so my loop is interupted. The errors don't really matter to me as all the other values might still be useful and therefore I

Hello , you've been written that file format is frozen. does this mean that i'll be able to play files, commpressed today, say, 1-2 years after? thereby the next question is coming. what kind of strategy do you plan to enable fast seeking? to write new seeking algoritm, or to add some data to .flac file. i ask of it because i want to write files on cd-r and so i'd like to know can i

HI I'm a student in chemical engineering, and i have to implement an algoritm about FIVE PARAMETERS INTERPOLATION for a calibration curve (dose, optical density) y = a + (c - a) /(1+ e[-b(x-m]) where x = ln(analyte dose + 1) y = the optical absorbance data a = the curves top asymptote b = the slope of the curve c = the curves bottom asymptote m = the curve X intercept Have you never seen

Hi, I want to describe an algoritm in the details section of an Rd file and I'm having trouble to ident the different text rows. Can someone tell me how I can ident text in Rd files ? Thanks EJ

I'd like to know a little about the internals of RSYNC. I am a little confused as to why RSYNC is using both the simple 32 bit algorithm and the MD4 checksum function on the same files. From my testing this causes a vast overhead that is clearly not represented by RCP (fairly obvious!). Removing checksumming from a secure whole-file LAN transfer brings RSYNC in line with the general

...--> DSL ---(300kbps)---> INTERNET Which is the recomended value I must set in my QoS setup for the maximum outbound bandwith of my ethernet interface ? The max of 300kbps or something less like 290kbps ? Especify less than the maximum available bandwith is advisable to ensure that the QoS algoritms goes fine, isn''t it ?

Dear all, I want to solve a score function by using Newton-Raphson algorithm. Is there such a fucntion in R? I know there's one called optim, but it seems only doing minimizing or maximizing. Thanks, Jimmy

now i''m read a lot of knowledge paper about traffic control in linux because now i''m try to develop and research about traffic shaper so can everybody tell me about my topic ... Is it can do for real???? my topic is " now, many organization use traffic shaper for control traffic and bandwidth because don''t want something example some mac address, ip address,
