similar to: dovecot and tcpwrappers

hi everybody having I believe sort of plain-vanilla config with section in 10-tcpwrapper.conf as per docs login_access_sockets = tcpwrap service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } /etc/hosts.deny contains: ALL: given_host and yet dovecot logins IMAP client in whereas other tcpwrapper aware

Hello, I run dovecot-2/Maildir/LDAP user/passdb and would like to be able to deny acess to users who connect from certain domains/IP (google.com for instance since in that case they gave their credentials to a third party). My understanding is that I cannot use some negative form of "allow_nets". The only mechanism I can think of is tcp_wrappers. However, dovecot documentation mention

Hello, we want to use dovecot LMTP for efficient mail delivery from our MX servers (running postfix 2.8) to our storage servers (dovecot 2.0.17). However, the one problem we see is the lack of access control when using LMTP. It apears that every client in our network who has access to the storage machines can drop a message in a Maildir of any user on that storage server. To prevent this

Hi, This is an early warning: OpenSSH will drop tcpwrappers in the next release. sshd_config has supported the Match keyword for a long time and it is possible to express more useful conditions (e.g. matching by user and address) than tcpwrappers allowed. Removing it reduces the amount of code in the 'hot' pre-authentication path in sshd and rids us of a dependency. -d

I have set up entries in /etc/hosts.allow and /etc/hosts.deny as follows: /etc/hosts.allow sendmail : 10.0.0.0/255.0.0.0 sendmail : LOCAL /etc/hosts.deny sendmail : ALL When I try to connect to port 25 from an Internet host via telnet, the server still responds as usual. The only difference I see is this in my /var/log/maillog: Apr 24 15:41:49 server sendmail[20691]: m3OKfna20691: tcpwrappers

Good Morning, I have a Centos 4.5 (x86_64) server running samba to share data with windows users. We've been going through a security audit and the following log entries were noted: [2007/09/24 09:37:29, 0] rpc_server/srv_util.c:get_alias_user_groups(206) get_alias_user_groups: gid of user bendew doesn't exist. Check your /etc/passwd and /etc/group files [2007/09/24 09:37:29, 1]

Hi! Apologies for sending the mail without any code. Apparently somewhere along the way the .R attachments got filtered out. I have included the code below as clean as possible. My original mail is below the code. Thank you again for your time. regards, Paul vincentize <- function(data, bins) { if ( length(data) < 2 ) { stop("The data is really short. Is that ok?"); }

Hello! I'm trying the hard way to use a formula, in a function, to specify the names of several important columns in a data.frame. Maybe I'm just battling to figure out the right search terms :-( This is on XP, R 1.8.1. So, for instance, wery[1:5,] V1 V2 V3 V4 V5 congr V7 V8 V9 ok RT 1 1 1 960 520 1483 c 1 r r 1 760 2 1 2 1060 450 3753 c 1 r r 1 555

Dear all, I have a piece of code along the lines of f <- function(x) { clipname <- "LK" # but is in real determined based on info in data.frame x # other manipulations return( list(clipname=list(....))) } My intention is to do out <- f(dat) and then (in this example) having/getting out$LK which is a list in itself. Of course, it doesn't work like this, but

I think the thread ended up with several people (not only me) feeling certain they didn't like `is.na<-` but with the developers defending it and me not really understanding why. Uwe Ligges was going to come up with an example of `<- NA` going wrong (sorry Brian R, I mean behaving unexpectedly), but never did, and I think the problem has been fixed. It was apparently a problem with

Hello! I'm not grasping why cbind (in the code below) warns that Warning message: number of rows of result is not a multiple of vector length (arg 2) in: cbind(z, p) when I do sections <- function(length, parts) { p <- 1:parts q <- length %/% parts z <- array(p, dim=c(parts,q)) r <- length %% parts if ( r > 0 ) { p[r+1:length(p)] <- NA z <-

Hello! If I read ?subset, the workings of the argument drop (to me) seem to imply equivalence of A and B (R 1.9.0): #A dd <- data.frame(rt=rnorm(10), c=factor(gl(2,5))) dd <- subset(dd, c==1) dd$c <- dd$c[, drop=TRUE] table(dd$c) 1 5 #B dd <- data.frame(rt=rnorm(10), c=factor(gl(2,5))) dd <- subset(dd, c==1, drop=TRUE) table(dd$c) 1 2 5 0 So to lose the second level of

Dear all, I am trying to shove a number of cmdscale() results into a single plot (k=1 so I'm trying to get multiple columns in the plot). From ?par I learned that I can/should set new=TRUE in either par() or the plot function itself. However with the following reduced code, I get only a plot with a column of data points with x==2. plot(1,10, xlim=range(0,3), ylim=range(0,10),

Dear all, Type III SS time again. This case trying to reproduce some SPSS (type III) data in R for a repeated measures anova with a betwSS factor included. As I understand this list etc, if I want type III then I can do library(car) Anova(lm.obj, type="III") But for the repeated measures anova, I need to include an Error-term in the aov() call (Psychology-guide from Jonathan Baron)

Hi after browsing the documentation and web, I'm completely lost as how to create the graph I describe below (as best as I can). I've got 3 pairs of average response times: (390,396), (416, 421), (406,415). Each of these pairs represents a level of a certain factor (let's call it 'loc'), namely (in the same order), levels "c", "nc" and "ni".

Hi! After a lot of testing and debugging I'm falling silent in figuring out what goes wrong in the following. I'm implementing the Vincentizing procedure that Ratcliff (1979) described. It's about calculating RT bins for any distribution of RT data. It boils down to rank ordering your data, replicating each data point as many times as you need bins and then splitting up the
