Hi, I know this question was posted back in 2002/2003, just wondering if the answer has changed since then :) There are various sites which say its possible to run Samba using NetBIOS over IPX: http://samba.anu.edu.au/cifs/docs/what-is-smb.html http://nlug.org/mail/nlug__1999_05/0057.html I've tried everything I know to (which admittedly isn't much) and can't get it to work (I

Hi R-Developers, I had a question about the random number generator used in the R StandAlone Math Library. The stand-alone library depends on the unif_rand() function for most simulated values, and this function is provided in the sunif.c file in the relevant directory. At present, this program implements the "Marsaglia-Multicarry" algorithm, which is described throughout the R

Hi all, I'm attempting to gap-fill a dataset, replacing the missing values with each month's day or night median value. The problem is that my code results in some, but not all the NA's being replaced and I cannot figure out how this is possible. When I look at the individual line's where the NA's remain, they should have been captured in my code as far as I can tell.

I've seen how to replace the NA's in a single column with a data frame *> mydata$ncigs[is.na(mydata$ncigs)]<-0 *But this is just one column... I have thousands of columns (!) that I need to do this, and I can't figure out a way, outside of the dreaded loop, do replace all NA's in an entire data frame (all vars) without naming each var separately. Yikes. I'm racking my

Hi Folks, I am doing a server swap out tomorrow and wondered if there was a utility that will copy user account details and their current passwords from one server to another (both CentOS 4) - there's only about 15 to do so it's not a major issue. Thanks Nigel Kendrick

I'd been hoping to move all of our site to ssh protocol 2 whilst we are still small enough to do this without serious pain, however the lack of authentication and connection forwarding is making that difficult at present. I see the current (2.2.0p1) code base does not have the code on either client or server side for ssh2 to handle tunneled connections or authentication agent. Is this

I know that there must be a cool way of doing this, but I can't think of it. Let's say I have an dataframe with NA's. > x <- data.frame(a = c(0,1,2,NA), b = c(0,NA,1,2), c = c(NA, 0, 1, 2)) > x a b c 1 0 0 NA 2 1 NA 0 3 2 1 1 4 NA 2 2 > I know it is easy to replace all the NA's with zeroes. > x[is.na(x)] <- 0 > x a b c 1 0 0 0 2 1 0 0 3 2 1

Hi, I have a vector where an integer is followed by a randomly varying number of NA elements. I want to replace the NA's with the preceding integer. Let me explain with a simple?example : avec<- c(1,NA,NA,5,NA,3,4,NA,NA,NA,NA,9,NA,0,NA,NA) I want to get the following vector from a : bvec<-c(1,1,1,5,5,3,4,4,4,4,4,9,9,0,0,0) How can I do this with R? Will appreciate all the help that I

As an experiment I set up Challenge/response authentication on a Linux system with PAM using a pam_opie module (this module works fine with console logins and su). I can log into the box using the opie password, *but* it does not give me the challenge - which can make things a little tricky :-) I can well believe this might be a fault in the PAM pam_opie module I am using, so has anyone got

Thanks to some of the guys on #samba-technical (obnox in particular!), I now have a working samba configuration. The environment: In our setup each user has an entry in both openldap (no samba schemes) and AD. Each account has the same name and even has a Unix UID entry in AD. Our users ssh into Linux boxes, authenticating off of openldap. Files are shared via samba. Due to the account

Hi A quicky - has anyone had success with an X100P in the UK ? I'm seeing some oddness - when I plug the wall socket into the card, I lose dialtone. If I unplug it, it comes back. Does this sound familiar to anyone ? Cheers Nigel Nigel Taylor Technology Director ITAzure Limited Dunn House Warren Park Way Enderby Leicestershire LE19 4SA 0116 286 3016

Long ago, when I wrote the ssh config file on my desktop box, ssh (which might have been the non-openssh one) took 3 possible values for the StrictHostKeyChecking option - yes, no & ask. Today, when I attempted to connect to a new machine, with no DNS entries (so using IP address) from my desktop box, ssh (now 2.3.0p1) SEGVed. Looks like there is some subtle interaction between having an

Greetings Running Fedora Core 3 and dovecot-0.99.13-3.FC3 as a production mail server for around 30+ accounts. A couple of times a day dovecot just stops. Nothing in the mail log except for Apr 26 00:48:19 sydsrv05 imap-login: Can't connect to auth process at default: Connection refused It's got to the point that I have put a script into cron.hourly to restart the dovecot service

Dear R Community, We have recently installed R 1.5.0 on several workstations. Ever since, if I try to extract certain numbers or lines from a file (which contains many NA's), I don't only get my desired line but all other lines which contain NA's. In a file with 15000 rows and 7500 NA's this is not very practical. In the earlier R-Version this worked when I typed in the

Hi, I''m trying to get RAdmin [uses tcp 4889] access to my Windows machine which is behind my firewall.

Stephen et al, You may remember me raising the point that the new e2fsprogs (1.25 as I remember) griped about old journals not having all the appropriate fields zeroed. I've just discovered that the RH 7.2 installer produces journals (ie on partitions created as ext3 from within the installer) that flag these warnings with a modified 1.25 e2fsck (the mods being to clear the errors rather

Hello all. At XMOS we are working towards updating the upstream XCore backend for newer versions of the chip. XCore is the XMOS processor. The XCore backend was written by Richard Osborne at XMOS. Richard has moved on. The current code owner in CODE_OWNERS.TXT, Robert Lytton, has also moved on. For some years XMOS has developed the compiler in-house, for new versions of the chip, but not
