OT: RIP settings for private netblocks
I am contemplating converting some of our internal networks from routable
to private IPv4 address space. I have a question about RIP as implemented
under Cisco IOS 12.x.
Presently the setting for rip is:
router rip
version 2
passive-interface [[FastEthernet]]0/0
network aaa.bbb.ccc.0
no auto-summary
What I would like to know is how one routes the entire 192.168/16 address
space using rip.

CentOS-6.7, kvm bridges, virtual interfaces, and routes
I have been looking at this problem on and off for a considerable
period. Given my lack of knowledge I have been unable to resolve this
quickly and in consequence it has been constantly shoved to the
background as other issues arise.
Here is the situation:
I have two dual-homed kvm hosts both running CentOS-6.7 and
identically configured. These are connected to the same LAN segment

OT: Setting a CentOS to gateway a private IP address
This is mildly off topic since it has more to do with TCP/IP networking
than with CentOS per se. However, at the risk of ruffling a few feathers
I would like some advice on how to resolve the following routing problem:
Given:
dual homed host running CentOS-5.2 with
eth0 = 2xx.yyy.zzz.23
eth1 = 192.168.219.1
and a Cisco gateway at 2xx.1xx.y7y.1 with the following networks:

Problem with yum
I am experiencing a problem with yum on one of my CentOS-5.5
systems. Specifically, on Friday past (July 16), I ran yum update
as root. Yum displayed all of the outdated packages and asked if I
wanted to proceed. An answered yes. This first package downloaded
was nss. At this point yum simply stopped processing or responding.

sip.conf and SIP client host= not recognized in some cases
I am seeing an issue with getting certain sip devices to be recognized as
defined SIP clients host= in the sip.conf and the only deference that I can
find btw sources that work and don't work is that devices that send packets
with an Initial Via header of themselves appears to work and pick the
context correctly but those that don't have the Via just get dropped in the
context of the

Can a matrix have 'list' as rows/columns?
After a lot of processing I get a matrix into M. I expected each row and
column to be a vector. But it is a list.
R-Inferno says...
"Arrays (including matrices) can be subscripted with a matrix of positive
numbers. The subscripting matrix has as many columns as there are dimensions
in the array—so two columns for a matrix. The result is a vector (not an
array)
containing the selected

Not routing for 1 host?
Hi,
I want to stop routing for 1 particular host in my network. I thought that this would do it:
iptables -D INPUT -d aaa.bbb.ccc.ddd -j DROP
iptables -D INPUT -s aaa.bbb.ccc.ddd -j DROP
But that still shows traffic. What is the corract way to do that?

var[i]
Dear all,
How could I use variables in a loop that their names are in a vector?
For example:
aaa <- 1:10
bbb <- aaa*2
ccc <- aaa+bbb
varn <- c("aaa", "bbb", "ccc")
m <- rep(NA, 3)
for (i in 1:length(varn)) m[i] <- mean(varn[i]) # wrong
thanks in advance

Help with routing question.
CentOS-6.6
We have a host that has multiple IPv4 addresses aliased to eth0. The
primary address is 216.185.71.x and the alias is 192.168.6.x.
This host connects to devices on both netblocks without problems.
Only default routing is used and it looks like this:
#ip route
192.168.6.0/24 dev eth0 proto kernel scope link src 192.168.6.x
216.185.71.0/24 dev eth0 proto kernel scope link src

"if" within a function
Dear Friends.
I found a puzzling phenomenon in R when you use 'if' within a function:
# defining a function aaa
aaa=function(a)
{if (a==1) {aaa=1};
if (a!=1) {aaa=2}
}
# using the function:
> b=20
> bbb=aaa(b)
> bbb
[1] 2
> typeof(bbb)
[1] "double"

> c=1
> ccc=aaa(c)
> ccc

> typeof(ccc)

Question regarding subsetting
I run R 2.1.1 in a Linux environment (RedHat 9) although my question

Consider the following:

I am new to R and am trying to merge data frames in the following way.
Suppose I have n data frames each with two fields. Field 1 is common among
data frames but may have different entries. Field 2 is different.
Data frame 1:

1 bbb
1 ccc
2 aaa
