On my network I have one Samba PDC (Version 3.0.28 running on FreeBSD 6.3-PRERELEASE), one mail server (FreeBSD + Dovecot + Postfix) and a dozen or so WinXP/Win2K machines. The WinXP/Win2K machines all have static IP addresses. The Windows clients are configured to look up the Samba PDC machine for both DNS and WINS. The Windows clients seem to be able to find other machines as well as the PDC:

hi, when I used cbind to combine columns, some contents of columns has been replaced by number. in the script below, column should be aaa,bbb,ccc but I was given 1,2,3. but when I change the column to vector, it gave me correct contents. can you please tell me why?   > d<-read.table("aaa.txt") > d    V1  V2 1 aaa 123 2 bbb 345 3 ccc 986 > cbind(d[,1],d[,2])      [,1] [,2]

I think I understand tapply but i still can't figure out how to do the following. I have a dataframe where some of the column names are the same and i want to make a new dataframe where columns that have the same name are averaged by row. so, if the data frame, DF, was AAA BBB CCC AAA DDD 1 0 7 11 13 2 0 8 12 14 3 0 6 0 15

Hi Thanks Gabor for your suggestion. I am posting the code that worked for me. dataframe1 = data.frame(cbind(Src = c(1,1,1,2,3), Target1 = c('aaa','bbb','ccc','aaa','ddd'))); #must be data frame dataframe2 = data.frame(cbind(Src = c(2,3,4,4,4), Target2 = c('aaaa','dddd','bbbb','eeee','ffff'))); dataframe3 =

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

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

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?

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 Juli -- "Wars do not solve problems, wars generate even more problems"

Hello, I am trying to setup a samba4 AD dc in my network using smb-tool. Everything seems to work except DNS forwarding. If I query for the dc root at dc:~# nslookup dc.local.domain.it I get the correct answer: root at dc:~# nslookup dc Server:???????? aaa.bbb.ccc.ddd Address:??????? aaa.bbb.ccc.ddd#53 Name:?? dc.xxxx.yyyy.it Address: aaa.bbb.ccc.ddd but if I query for an external domain: root

I run R 2.1.1 in a Linux environment (RedHat 9) although my question is not platform-specific. Consider the following: > A <- c("Prefix-aaa", "Prefix-bbb", "Prefix-ccc") > B <- strsplit(A, "-") > B [[1]] [1] "Prefix" "aaa" [[2]] [1] "Prefix" "bbb" [[3]] [1] "Prefix" "ccc" How

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 NULL > typeof(ccc) [1] "NULL" It seems that only the last

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.

I recently moved my Asterisk configuration to a new server and re-built Asterisk from CVS. Now, I'm experiencing the following issue with SIP: Executing Dial("Zap/1-1", "SIP/100|20") in new stack NOTICE[-1232077904]: File app_dial.c, Line 518 (dial_exec): Unable to create channel of type 'SIP' == Everyone is busy at this time Has anyone seen this issue before?

Hi R users, 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: Src Target1 1 aaa 1 bbb 1 ccc 2 aaa 3 ddd Data frame 2: Src Target2 2 aaaa 3 dddd 4 bbbb 4
