After some digging I found the solution on http://docwiki.cisco.com/wiki/Disable_LRO:

Log into the ESXi host or its vCenter with vSphere Client.
Select the host > Configuration > Software:Advanced Settings.
Select Net and scroll down slightly more than half way.
Set the following parameters from 1 to 0:

Net.VmxnetSwLROSL
Net.Vmxnet3SwLRO
Net.Vmxnet3HwLRO
Net.Vmxnet2SwLRO
Net.Vmxnet2HwLRO

Reboot the ESXi host to activate these changes.

The HUAWEI E1750 is sold under different names, some people report it as E220 or E1752. You should check in /proc/bus/usb/devices what is the vendor and product id of your 3G modem. You should see the following values:
vendor=0x12d1 product=0x1446

This howto should apply to all 3G USB modems with the same vendor and product id and any AP running OpenWRT Kamikaze 8.09.2.
Here is how I got the whole thing running:

1. Install the required kernel modules and utilities:


# opkg update
# opkg install kmod-usb-acm kmod-usb-core kmod-usb-ohci kmod-usb-serial comgt \
kmod-usb-serial-option kmod-usb-storage kmod-usb-uhci kmod-usb2 usb-modeswitch


2. Create or edit the file /etc/modules.d/60-usb-serial so that it only contains the following line:

usbserial vendor=0x12d1 product=0x1446

3. Create or edit the file/etc/usb_modeswitch.conf so that it looks as follows:

DefaultVendor= 0x12d1
DefaultProduct=0x1446
TargetVendor= 0x12d1
TargetProductList="1001,1406,140c,14ac"
CheckSuccess=20
MessageEndpoint=0×01
MessageContent="55534243123456780000000000000011060000000000000000000000000000"


4. Add the following section to /etc/config/network:

WARNING!!! Depending on the model of your 3G modem you may need to replace ttyUSB0 with ttyUSB1, ttyUSB2, etc. Check the output of “dmesg” to know which is the correct port. If you are unsure, find out by trial-and-error.

config 'interface' 'ppp0'
option 'ifname' 'ppp0'
option 'proto' '3g'
option 'device' '/dev/ttyUSB0'
option 'apn' 'YOURAPNHERE'
option 'pincode' 'YOURPINCODEHERE'

Replace YOURAPNHERE with the name of your APN (e.g. “tre.it” for H3G Italy) and YOURPINCODEHERE with the PIN code of your SIM.

WARNING!!! If you have disabled PIN code verification for your SIM, you can omit the pincode option but you’ll need to workaround a bug in /lib/network/3g.sh. Open /lib/network/3g.sh in your editor and comment out the following lines:

# PINCODE="$pincode" gcom -d "$device" -s /etc/gcom/setpin.gcom || {
# echo "$cfg(3g): Failed to set the PIN code."
# set_3g_led 0 0 0
# return 1
# }


5. Reboot your OpenWRT device.

6. Manually run the following commands and after a minute verify that your 3G connection is working:

usb_modeswitch
ifup ppp0


7. Add the following lines to the top of /etc/rc.local:

sleep 3
/usr/sbin/usb_modeswitch
sleep 3
/sbin/ifup ppp0

8. Log on the web interface of your OpenWRT device and click on Administration/Networks/Interfaces/ppp0 and add it to the WAN zone.

You may need to adjust the DNS settings manually.

I wanted something easy to automate that. Here is a simple Automator written in AppleScript which will take care of that:

on GetPart(s, p, d)
set theList to every text item of s
return (item p of theList)
end GetPart
on run {input, parameters}

end run

Of course I wanted to also enable video automatically when answering calls from specific contacts. Fortunately Skype Extender does just that!

I struggled with Nokia PC Suite, Nokisoft, and some nfb python scripts before realizing that I was actually looking at a zip archive of my phone filesystem!

Wow, so it’s really this easy:

• rename the backup from backup.nbf to backup.zip
• unpack it with: unzip backup.zip (or using winzip)
• search for .vcf files inside the archive. In my case they were located under predefhiddenfolder/backup/WIP/32/contacts
• YMMV

Converting the .vcf files to something which vaguely resembles a .csv file is trivial.

I used an ugly oneliner to do it. Here it comes for your pleasure:

$ cat *.vcf |grep -v ^VERSION|grep -v ^BEGIN|grep -v ^END|cut -d ':' -f 2- |sed 'N;s/\r\n/,/;s/;/ /'

• LAN: 192.168.0.1 connected to eth0
• ADSL1: $IP1 connected to eth1
• ADSL2: $IP2 connected to eth2

$IP1 and $IP2 are my public IP addresses.
Their respective default gateways are $GW1 and $GW2.

I use IP source routing to accept incoming connections from $IP1 and $IP2.
This is the easy part: there is a lot of documentation (see LARTC website for the details) on how to do this, I’ll just sum it up here for completeness.


ip route add default via $GW1 table adsl1
ip rule add from $IP1 table adsl1
ip route add default via $GW2 table adsl2
ip rule add from $IP2 table adsl2
ip route add default via $GW1

echo 200 adsl1 >>/etc/iproute2/rt_tables
echo 201 adsl2 >>/etc/iproute2/rt_tables

If somebody connects to $IP1 on port 22, LinuxFW receives packets on eth1 and outgoing packets are sent through eth1, thanks to the iproute2 rules mentioned above.
Similarly, if somebody connects to $IP2 on port 22, packets enter from eth2 and exit from eth2.

So far so good. Now comes the hard part:

I added a new Linux box behind the old one, let’s call it LinuxMail. The new box has IP address 192.168.0.2 and is running Postfix. It’s connected to the same LAN switch that LinuxFW has on “eth0″.
Obviously I could install a smtp proxy on LinuxFW and redirect all emails from LinuxFW to LinuxMail, but this poses some tread-offs, i.e.:

• LinuxMail won’t be able to see the IP addresses of incoming connections directly
• LinuxMail won’t be able to do connection throttling
• LinuxMail won’t be able to reject messages for non-existant accounts

All these problems can be solved to some degree by introducing more logic on the smtp proxy of course, but let’s assume that we don’t want to do that, either because LinuxFW doesn’t have enough resources or because we want to keep things simple.
There are three solutions to this problem.

iptables -t nat -I PREROUTING -i eth1 -p tcp --dport 25 -j DNAT --to 192.168.0.2:25
iptables -t nat -I PREROUTING -i eth2 -p tcp --dport 25 -j DNAT --to 192.168.0.2:25
iptables -t nat -A PREROUTING -i eth1 -m conntrack --ctstate DNAT --ctorigdst $IP1 -j MARK --set-mark 0x6
iptables -t nat -A PREROUTING -i eth2 -m conntrack --ctstate DNAT --ctorigdst $IP2 -j MARK --set-mark 0x7

All incoming packets with destination port 25 coming from either eth1 or eth2 will be redirected to 192.168.0.2 and marked respectively with “0×6″ and “0×7″. These iproute2 rules will take care of routing the reply packets to the appropriate interface:

ip rule add fwmark 6 table adsl1
ip rule add fwmark 7 table adsl2

Here is a simple way to open port 25 on both $IP1 and $IP2 and redirect incoming connections to LinuxMail using CONNMARK:

iptables -t nat -I PREROUTING -i eth1 -p tcp --dport 25 -j DNAT --to 192.168.0.2:25
iptables -t nat -I PREROUTING -i eth2 -p tcp --dport 25 -j DNAT --to 192.168.0.2:25
iptables -t mangle -A PREROUTING -i eth1 -m state --state NEW,RELATED,ESTABLISHED -d $IP1 -p tcp --dport 25 -j CONNMARK --set-mark 6
iptables -t mangle -A PREROUTING -i eth0 -m connmark --mark 0x6 -j CONNMARK --restore-mark
iptables -t mangle -A PREROUTING -i eth2 -m state --state NEW,RELATED,ESTABLISHED -d $IP2 -p tcp --dport 25 -j CONNMARK --set-mark 7
iptables -t mangle -A PREROUTING -i eth0 -m connmark --mark 0x7 -j CONNMARK --restore-mark

Of course you will still need the usual:

ip rule add fwmark 6 table adsl1
ip rule add fwmark 7 table adsl2

Another DIY solution is to assign a second private IP address to LinuxMail. In this scenario LinuxMail has the following IP addresses:

192.168.0.2

192.168.0.3

and LinuxFW redirects incoming connections from $IP1 to 192.168.0.2 and from $IP2 to 192.168.0.3:

iptables -t nat -I PREROUTING -i eth1 -p tcp --dport 25 -j DNAT  --to 192.168.0.2:25
iptables -t nat -I PREROUTING -i eth2 -p tcp --dport 25 -j DNAT  --to 192.168.0.3:25
iptables -t mangle -I PREROUTING -i  eth0 -s 192.168.0.2 -p tcp -j MARK --set-mark 0x6
iptables -t mangle -I PREROUTING -i eth0 -s 192.168.0.3 -p tcp -j MARK --set-mark 0x7

Of course you will still need the usual:

ip rule add fwmark 6 table adsl1
ip rule add fwmark 7 table adsl2

• Creare la directory /usr/lib/opkg: mkdir /usr/lib/opkg
• Modificare il file /etc/opkg.conf come segue:
  src snapshots2 http://downloads.openwrt.org/kamikaze/8.09.2/rb532/packages/
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option force_space


Fate attenzione però! L’opzione force_space fa sì che non vengano ignorati controlli sullo spazio libero effettivamente disponibile prima dell’installazione dei pacchetti. Dovrà essere vostra cura verificare di avere spazio disponibile a sufficienza in /jffs2 prima di procedere con l’installazione di nuovo software.

Searching for the right subtitle for a specific avi file can be frustrating. It’s not enough to match the filename. It’s always better to rely on the hash of the movie to find a properly sync’ed subtitle.

Fortunately, OpenSubtitles.org started offering a nice and easy interface to search their subtitle database. Here is a simple script I found on opensubtitles.org site and modified for my needs. It will help you to find the subtitles for your favourite movies and tv series:

use strict;
use warnings;
my $file = $ARGV[0];
unless (defined($file) and -r $file) { print "Syntax: $0 /path/file.avi\n"; }
my $hash = OpenSubtitlesHash($file);
print "

my $filename = shift or die("Need video filename");
open my $handle, "<", $filename or die $!;
binmode $handle;
my $fsize = -s $filename;
my $hash = [$fsize & 0xFFFF, ($fsize >> 16) & 0xFFFF, 0, 0];
$hash = AddUINT64($hash, ReadUINT64($handle)) for (1..8192);
my $offset = $fsize - 65536;
seek($handle, $offset > 0 ? $offset : 0, 0) or die $!;
$hash = AddUINT64($hash, ReadUINT64($handle)) for (1..8192);

return UINT64FormatHex($hash);

return [unpack("vvvv", $u)];

my $o = [0,0,0,0];
my $carry = 0;
for my $i (0..3) {
if (($_[0]->[$i] + $_[1]->[$i] + $carry) > 0xffff ) {
$o->[$i] += ($_[0]->[$i] + $_[1]->[$i] + $carry) & 0xffff;
$carry = 1;
} else {
$o->[$i] += ($_[0]->[$i] + $_[1]->[$i] + $carry);
$carry = 0;
}
}
return $o;
}
sub UINT64FormatHex {
return sprintf("%04x%04x%04x%04x", $_[0]->[3], $_[0]->[2], $_[0]->[1], $_[0]->[0]);
}

The problem can be easily fixed by changing line no. 507 from:

read_size = min(64*1024, max_size)

to:

read_size = min(64*1024, max(max_size, 512))

The problem also occurs if you forget to pass “–exclude /selinux” to duplicity.
