Traffic shaping on CentOS
I've been trying to do traffic shaping on one of my public servers and
after reading up, it seems like the way to do so is via tc/htb.
However, most of the documentation seems at least half a decade old
with nothing new recently.
Furthermore, trying to get documentation on tc filters turned up a
blank. man tc refers to a tc-filters (8) but trying to man that gives

4.8-Stable DummyNet
Hi. We just opened a gaming center and have chosen to run a FreeBsd box for
our firewall. IPFW is configured at it's very basic running natd through rl0
and allowing any to any connections from the lan to the outer world. Natd
controls access to the lan.
We have a 6.0 mb/s ADSL net connection for all the gaming clients to use,
however if a gamer starts downloading a file, that file

An error message I don't recognize
I have recently been told I will have to maintain some CentOS servers at
work. Since I have only been using Slackware for the last 16 years, I
decided to install CentOS on one of my servers at home to get an idea of
the differences. I installed CentOS 5.4 from CD with no problems, did a
yum update, set up a couple of samba shares and started to copy over
some files from one of my other

Removable drive configuration
I have a box running CentOS 5.3 with two Dataport removable drive bays
installed on the second IDE interface (/dev/hdc and hdd). I want to
configure it so I can plug in and mount various drives at different
times, including different size drives. So far it will only recognize
the first drive I plug in, and only if I boot the box after inserting
the drive.
Is there any way to set it up so I

Equal bandwidth configuration among host with dummynet
Hi all,
First of all, I have spent a lot of time reading up on
it.
Anyway, I live in a shared accomodation with 2
roommates and a landlord and we share a cable internet
connection. It is 2Mbit/400Kbit connection. Sometimes
when one of us is downloading a song through Kazaa or
a new Linux or FreeBSD iso, the bandwidth gets hogged
and other users can't get through.

https question
Hi
I have question about https
I am using mozila to access gmail as https://mail.google.com/mail
Why mozilla prompts me the alert box?

How mozilla knows I have data not encrypted?

CentOS Digest, Vol 60, Issue 13
Another issue to consider with SSDs is that they are based on Flash technology. Each flash cell can only be written on about 10,000 to 100,000 times or so (*), so if you're using extensive read/write on your server you will be impacted. SSD manufacturers go around this issue by giving some intelligence to the drive controllers, so that they minimize the per-cell usage (which means moving

Problem with checkinstall
I installed checkinstall 1.6.2 on CentOS 5.4 VM (VMWare Server on
WinXP). After getting the dependencies installed it compiled with no
errors. But when I run it in its own source directory, I keep getting an
error that I can't track down. The message is:

Bash Script Shorcuts for Steam Games
Hi there,
I was just wondering how I would go about creating a bash script for Steam apps. I just started college in Pre-Biochem. and Pre-Comp. Sci. so I'm not far enough in yet (and midterms are coming up, how embarrassing) but the point is, I don't know how to create a bash script for steam apps.
I know they start up steam first, then log in, and then get into the game. I'm not

I/O descriptor ring size bottleneck?
Hi everyone,
I''m doing some networking experiments over high BDP topologies. Right
now the configuration is quite simple -- two Xen boxes connected via a
dummynet router. The dummynet router is set to limit bandwidth to
500Mbps and simulate an RTT of 80ms.
I''m using the following sysctl values:
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096

4.8-STABLE Kernel Panic with dummynet options.
I first met this problem when our (60 students) internetgateway refused to
boot its new kernel, it was a 4.7-RELEASE. Then i loaded the old kernel and
went home to check if my 4.8-STABLE does likewise. And the answer was yes!
Both kernels were GENERIC + these options taken from the dummynet man pages:
options DUMMYNET
options NMBCLUSTERS
options HZ

Invoking SAS in order to use sas.get
I am trying to use the sas.get function to bring a SAS dataset into R.
After calling the sas.get function I got an error message stating that
'sas' is not a recognized internal or external command, etc. I am
guessing that I need to specify the internal command to invoke SAS in
the sasprog option for the sas.get function, but I don't know how to
determine what that command might be.

modeling logit(y/n) using lrm
I have a dataset at a hospital level (as opposed to the patient level)
that contains number of patients experiencing events (call this number
y), and the number of patients eligible for such events (call this
number n). I am trying to model logit(y/n) = XBeta. In SAS this can be
done in PROC LOGISTIC or GENMOD with a model statement such as: model
y/n = <predictors>;. Can this be done

phase determination
Hi,
I'm trying to determine the phase of irregularly sampled data. Is there any
particular reason why both spec.pgram and spec.ls return phase<-NULL for
vectors?
Thank you.

blues in c
G'Day,
I'm a little confused why the c function has the followng effect on
classes - is this a feature ? My workround [ class(cc) <- c("POSIXt",
"POSIXct") ] seems to do the job.
Many thanks

accessing current factor in tapply
G'Day,
I want to access in a function called from tapply the current factor. In
my example below, all I want to do is to write the current factor on each
histogram. Needless to say my example does not work. I would be grateful
for pointers in the right direction.
Many thanks
