Hi, I'm relatively new to linux world.I'm just trying to setup a bridge firewall between a router and LAN. I've installed Red Hat Linux 9.0 - 2.4.20-8 from installation CDs and upgraded to 2.4.25 successfully. I've patched my kernel to support bridge firewall also loaded ebtables module,so far so good.Now I tried to create a bridge using the code given in the following link

Hi, I've set up a bridge using the 2.6.11.6 kernel. The machine is running Debian testing with three NICs in it. eth0 is a standard 100Mb Intel NIC, eth1 and eth2 are both Intel gigabit cards using the e1000 driver. I tested everything at 100Mb and it worked fine. I moved the machine into production, eth1 plugging into a dumb 100Mb D-link switch, eth2 plugging into a shiney new Cisco

Hi, I'm trying to do PCA on a n by p wide matrix (n < p), and I'd like to get more principal components than there are rows. However, svd() only returns a V matrix of with n columns (instead of p) unless the argument nv=p is set (prcomp calls svd without setting it). Moreover, the eigenvalues returned are always min(n, p) instead of p, even if nv is set: > x <-

Hi, I'm trying to use Frank Harrell's Design:::ols function to do regression of y (numeric) on the interaction of two factors (x1 and x2), but Lapack throws an error: > library(Design) ... > load(url("http://www.csse.unimelb.edu.au/~gabraham/x")) > ols(y ~ x1 * x2, data=x) Error in chol2inv(fit$qr$qr) : 'size' cannot exceed nrow(x) = 20 > traceback()

Hi, I'm doing PCA on wide matrices and I don't understand why calling predict.prcomp on it throws an error: > x1 <- matrix(rnorm(100), 5, 20) > x2 <- matrix(rnorm(100), 5, 20) > p <- prcomp(x1) > predict(p, x2) Error in predict.prcomp(p, x2) : 'newdata' does not have the correct number of columns > dim(x2) [1] 5 20 > dim(p$rotation) [1] 20 5

Hi, I'd like to store large covariance matrices using Matrix classes. dsyMatrix seems like the right one, but I want to specify just the upper/lower triangle and diagonal and not have to instantiate a huge n^2 vector just for the sake of having half of it ignored: Dumb example: M <- new("dsyMatrix", uplo="U", x=rnorm(1e4), Dim=as.integer(c(100, 100))) diag(M) <- 1

Hi, I'm using Ubuntu Hardy i386, and the R 2.7.1 Ubuntu packages from CRAN. The CRAN r-base-dev package depends on refblas3-dev or atlas3-base-dev, but octave3.0-headers depends on libblas-dev. The two blas packages seem to conflict, so r-base-dev and octave3.0-headers can't be installed together. Is this a known issue? Thanks, Gad $ sudo apt-get install octave3.0-headers Reading

Hi, I'm using Ubuntu 9.10 amd64 with cran2deb packages (I know it's meant for Debian, it's worked fine for me for many months). Recently apt-get update has to started to complain: ...

Hi, I have two example packages, test1 and test2, where the only code in them is: setGeneric("predict", function(object, ...) standardGeneric("predict")) (get them from http://www.cs.mu.oz.au/~gabraham/test1.tar and http://www.cs.mu.oz.au/~gabraham/test2.tar) The difference between them is that first does not have a namespace, and loads fine. The second has a namespace

Hi all, Have had a frustrating time trying to get R 2.5.1 running happily on Solaris9/x86, the problems seem to stem mainly from libiconv support. After a couple of hours of experimenting, I came across the following combination, note that iconv (the program, but not the library) exists in the Solaris base system, I've manually installed the full GNU distribution in

Hello, I am the author of the Bonk audio compression program... i've just been looking at your comparrison table, and i noticed bonk gets marginally better compression than Flac on some files (actually i was rather surprised to see bonk on the list at all, it's not exactly high profile :-) ). Bonk in lossless mode is a pretty naive implementation of a predictive coder, so the main

Running on Centos 5.6 with KVM... I was wondering if anyone had any luck configuring the NICs where eth0 and eth1 are bonded together with vlan support to a bridge? I noticed some threads show this as a possibility (http://lists.centos.org/pipermail/centos-virt/2009-November/001417.html), but haven't had any luck implementing it. There also seems to be a bug with 5.6

Hi All, I'm having some problems getting postfix to relay mail. I'd appreciate any tips. Perhaps there are some settings which I may have missed, somewhere. The postfix mail server is on VLAN 250 (192.168.250.0) whilst I have several other users on other VLANs (e.g. 91, 92, 93, etc... 192.168.91.0, 192.168.92.0, 192.168.93.0, etc...). So, if I had a PC sitting on VLAN 91 with IP

Shifting from a v2 samba server to v3 - Read documentation and googled LOTS but can't seem to find the bits that apply to my simple(?) server with regards to groups. # rpm -qi samba Version : 3.0.28 Vendor: Red Hat, Inc. Release : 1.el5_2.1 Source RPM: samba-3.0.28-1.el5_2.1.src.rpm Samba on server (Red Hat Enterprise Linux 5.2) IS MOSTLY WORKING... home directories

OK, strange request but I want to bridge three vlans under linux 2.4. Bridging works fine with two vlans, but is failing to route when I add the third vlan. Situation is clearly to have Lan, internet and DMZ vlans. The reason they are vlans is that I am using a Linksys WRT54GS and hence you effectively have a 5 port hub on the back which can be segregated into flexible vlan groups. I

Hi all How much does configuring a network with VLANs improve or effect quality ? Is there much reason to justify the configuration of VLANs ( I know networking, but not VLANs at all) Would it not be better to find high traffic users and determine why? Your Thoughts Thanks Barry

Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played with VLAN's a bit on the switch and at this point have two: VLAN 1 (which is default and can

Hi, Again I'm doing logistic regression using lrm from Harrell's Design package, but on wide matrices (28 observations, 1891 variables) so L2 penalisation is used. I get the following error, although I've tried different penalties and different tolerances. The X matrix is scaled and centred. > library(Design) >

Hi, I'm using Vlans in my network as a way of preventing pier to pier communication - I only want nodes in the network to talk to the gateway (a linux box). I have successfully set up lots of sub interfaces using the vconfig too, one for each vlan. What I would like to be able to do is remove the ip address from each of these subinterfaces eth0.x and bridge them to eth0. I have successfully

Hello, Is it possible with a linux Bow to route différents VLANs, like a router cisco can does ? Thank for your answers Laurent Foucher _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
