Sorry - the tcpdump command should end with "192.168.1.1" instead of

Try this on your VPN_office host:
tcpdump -npi any icmp and host 192.168.1.3
In parallel you start a ping from the other network:
ping 192.168.1.1
I assume, that tcpdump will show all packets from

a good step forward :)

OK. The output tells us, that there are firewall rules.
Now you should take a look at your firewall configuration

Cannot access other computers on LAN
I cannot even ping the LAN router on 192.168.1.1, but if I ssh though the
tunnel to 192.168.1.3, I can ping it.
Investigating with tcpdump withoug guidelines is beyond my skills I'm
afraid.
I used tinc in router mode because it is proposed like in most howto I
found... Would just switching to switch mode makes things easier or that's
not related?

Cannot access other computers on LAN
Hi Lars,
Thanks for the help
** Test 1 **
On VPN_office I use 'tcpdump -npi any icmp and host 192.168.1.3'
When pinging 192.168.1.1 from client 1, with no success, I see no packet
passing.
When pinging 192.168.1.3 from client 1, with success, I see packet passing:

ip_forward was not enabled, now it is. Still same result:
On VPN_office I use 'tcpdump -npi any icmp and host 192.168.1.1' and ping
192.168.1.1 from the client:

Cannot access other computers on LAN
In most howtos it is instructed to enable port forwarding with 'echo 1 >
/proc/sys/net/ipv4/ip_forward', but they don't say it's not permanent... So
it was gone when I rebooted the machine.
I then disabled the firewall on the VPN_office machine... And it works! If
obviously VPN_out must be highly secured, I guess there is no problem to
disable the firewall on VPN_office?

Tinc and firewall
Hello,
Early this year I got help here to setup tinc tunnels between users and a
company LAN. Now I would like to try something different for a home usage
and I have a question regarding security.
The setup would look like as follows:
- My home LAN has a classical topology where my ISP router is doing NAT and
is blocking all incoming connection. I'm planning to enable port forwarding

Cannot ping subnet hosts
I have done it... added on both routers a new firewall zone covering the
tinc interface, policy in accept, out accept, fwd accept, interzone
forwarding from/to LAN.... when I do it, I am not even able to ping the
routers between them, even though the PING PONG is ok in the tinc debug....

FDR analyses: minimum number of features
Dear List,
We are planning a genotyping study to be analyzed using false discovery
rates (FDRs) (See Storey and Tibshirani PNAS 2003; 100:9440-5). I am
interested in learning if there is any consensus as to how many
features (ie. how many P values) need to be studied before reasonably
reliable FDRs can be derived. Does anyone know of a citation where
this is discussed?

Cannot ping subnet hosts
Dear all,
I am trying to configure a basic TINC vpn between two sites using OpenWRT
routers. The link seems to work, the ping between the two routers is ok,
but I can't ping hosts between the subnets behind the routers.
This is the configuration:
======== SITE 1 (CLIENT) - polimnia (subnet 192.168.4.0/24, gw 192.168.4.1)

is.Date function question
Why is there no is.Date function in R? I am running 2.1.1 does it exist
in newer version? If there is a reasoning behind the lack of a is.Date
function what is it?
Thanks

All,
I'm trying to configure a Samba 3 AD member server including winbind. I'm on RHEL 6.6, so I'm using Samba version 3.6.23.
Here's my configuration:

workgroup = ABC
server string = LV37
netbios name = LV37
idmap config *:backend = tdb
idmap config *:range = 2000-9999
