Dear R users I want to compute Kendall's Tau between two vectors x and y. But x and y may have zeros in the same position(s) and I wrote the following function to be sure to drop out those "double zeros" "cor.kendall" <- function(x,y) { nox <- c() noy <- c() # for (i in 1:length(x)) if (x[i]!= 0 | y[i] != 0) nox[length(nox)+1]<- x[i] for (i in

Hi, it looks like save() is saving all contents of the calling environments if the object to be saved is *not* evaluated, although it is not that simple either. After many hours of troubleshooting, I'm still confused. Here is a reproducible example (also attached) with output. I let the code and the output talk for itself: peek <- function(file, from=1, to=500) {

There has been numerous threads etc regarding this but all that has left me is more than a little confused :-(. I have setup and environment consisting of two OpenVPN tunnels and wish to load balance at the packet level between them. I am currently running on Linux edm 2.4.21-20.EL.c0custom #2 Tue Oct 12 08:52:23 BST 2004 i686 i686 i386 GNU/Linux And have install Quagga at each end to provide

HI List, How do i reset the values in /proc/net/dev ? This file holds values for count of each (packet && byte), (sent && received) through all interfaces. I''m using a monitor which reads values from this file and prints out some nicely formatted output. But i need to reset the values. ie. set then to zero. Restarting the network does not do what i want. I guess a reboot

Hi, I''m setting up a router (linux, debian-sarge), which shall relay dhcp requests from all subnets to a central DHCP server. The general stuff is solved, i.e. I can ping from any connected machine to any other including the NICs of the router itself. All firewall tables (including nat and mangle) are set to ACCEPT and flushed. On my model system I have the NIC 172.16.1.121 (eth1),

Hi, after migrating to shorewall firewall from my own iptables rule set (to utilise freeswan vpn tunnels) I have successfully configured a 3 interface firewall with net2net vpn tunnels, with the help of the shorewall documentation. However I cannot seem to configure my final step which is to masq another subnet attached to my LAN (LANB, via Cisco 1603 router) to get internet access via the

Problem: I have four networks, A, B, C, and D Networks B, C, and D should not be able to see each other. Network A should be able to see all of them. A - 172.16.1.1/24 B - 172.16.2.1/24 C - 172.16.3.1/24 D - 172.16.0.1/24 For host machine X, which is at 172.16.1.100/24 (network A), I added a route for it to ping a machine (Y) on the network B:     ip route add 172.16.2.0/24 via

Of course you should patch/upgrade, etc. A stopgap measure could be to use static ARP for a segment. I have done this for a long time with wireless hosts, since I'm in an urban environment with many visible nodes, some in autos, and ARP cache poisoning is a well-known DoS against wireless. You may find it extremely painful and less-than-useful to have static IP addrs, etc. for hosts.

Hi all, Does any one know if this is normal operating of ARP. Or where to start looking. I am seeing a lot of ARP requests for my router IP from the same IP within seconds. 21:04:41.112929 arp who-has IP tell MY ROUTERS IP 21:04:41.186354 arp who-has IP tell MY ROUTERS IP 21:04:41.372972 arp who-has IP tell MY ROUTERS IP 21:04:41.546921 arp who-has IP tell MY ROUTERS IP

Hi all. I experienced a strange behaviour in the "arp" command when I use the "pub" (publishing) flag. This is the scenario (I know it''s an unusual one, but it''s just for a test): __________ | | | host C | | | |__________| | __________|________________________________

I am attempting to discern the efficacy of controlling or filtering ARP (gateway/client) to mitigate unauthorized connections to wifi networks. As such, I am aware that EAP was originally devised to allow for: " the negotiation of an authentication protocol for authenticating its peers BEFORE allowing network layer protocols to transmit over the link" (RFC2284) However, this
