[Bridge] Passing vlan tagged packets through linux bridge
...when I have added the eth0 and eth1
to br0 the bridge doesn't forward tagged packets larger than
1472 bytes. I remember that with older kernels (<2.6.15)
large tagged packets was forwarded.
What is the problem? Any chance to have a patch?
Thanks in advance for your answers.
Best Regards

Patch for GRUB Legacy to chainload SYSLINUX from logical partitions
Inspired from a similar patch posted on grub-devel for Grub2 I immersed
myself into the code of Grub Legacy and came up with this absurdedly simple
patch to allow syslinux or other bootloaders residing in logical partition
to be chainloaded from GRUB Legacy (0.9x).
Hoping it to be of help, regards
Fulvio Scapin

[Bridge] large packet size doesn't work
...ed two
ethernet interfaces (with MTU 1500) in bridge mode. CONFIG_BRIDGE_NETFILTER
is enabled.
The problem is that ping -s 1500 192.168.0.2 doesn't work from 192.168.0.1
if the systems are separated by the bridge. Normal ping with smaller packet
size works ok.
What is wrong?

Syslinux boot from a partition on sub stick with GPT label
...irst four paritions work as expected sounds suspiciously
related to a situation involving the use of a dos label to me. Could anyone
explain to me where the problem lies:
with syslinux and gpt, with grub2 and gpt or somewhere else?
Thanks in advance and forgive me should I have wandered off-topic.

linear regression of data with standard deviation
Hello everyone,
I know that to calculate the linear regression between x and y I
have to use the function "lm".
But how to do if x and y have a standard deviation like in the
following example?
How to compute the chi square test in this case?
Thank you,
Fulvio.
example:
x +- dx
5 2
13 4
17 4
23 6
y +- dy
6.3 0.6
9.2 0.9
14 1

saving variables created by functions in the workspace
Hello ,
just a simple question from a beginner:
I write the function:
plotsinx <- function()
{
x<-seq(0,2*pi,0.01)
sinx<-sin(x)
plot(sinx)
}
I recall it:
plotsinx()
and the plot works properly.
but then in the workspace if I want to look at the
values of sinx the following error is displayed:
Error: Object "sinx" not found.

I'd like to know if is it possible to make a 3D scatter plot (x y z) using R.
In the on-line help and in the help mailing list I found only ways in which

I created a simple histogram with:

Since myHist$counts contains some "0", and I want to calculate the linear fit among myHist$mids and log(myHist$counts), I want remove the elements of both arrays where these "0" occurs.

Force file read even with checksum error
...rupted...
Is there a way to force zfs to give me the whole file so I can compare it to my backup?
Is there a way to get zfs to give more specifics on the checksum issue (i.e. which block, where in file, etc.)?
Thanks,

questions about ZFS Send/Receive
..."receiving mode":
in poor words is it possible to read and export in nfs, files from a
ZFS file system while it is receiving update from another ZFS send ?
Clearly until the new updates are received and applied the old copy
would be used
TIA

call R scripts from python
Hello,
I have just learnt some python, and would like to call R scripts from python, without using batch mode.
I learnt how to do it from perl, in fact reading in the mail archive I found the following good example:
***************************************
#!/usr/local/bin/perl
open (FILE, ">test.txt");
print FILE "a,b,c,d,e\n1,2,3,4,5";
close FILE;

CRAN downtimes
Hi,
we had a broken heating system (in the floor above us) resulting in a
water burst .... my office looks like if a bomb has exploded ...
Currently our server is up and running again (it was down over the
weekend) ... but we will move out of the devastated rooms and hence
the CARN master might be down one or more times during the rest of the
week. We'll try to keep the down times as short
