Any ideas?

Comment on OpenVPN over TCP is BAD by Kristopher Morris

Kristopher Morris — Thu, 03 May 2012 08:42:18 +0000

We run a small vpn provider free ads http://www.vpnpop.com been playing with openvpn for awhile now and I have some numbers. With proper HTB class based shaping UDP is over 3x faster on a generic speedtest.net. You basicly nailed it; you can improve TCP to some extent by forcing MTU’s and few other directives. Let us know if you need servers to test! also lzo seems to be bad on lossy links. Running TCP_Westwood on the clusters helps with that alot.

Thanks, worked perfectly on a HP ProLiant DL380G5 with an iLO 2 mgmt card. No need to buy the expensive advanced license for the iLO2 now!

Nice post. I study something more difficult on completely different blogs everyday. It’s going to at all times be stimulating to read content from different writers and observe a little one thing from their store. I choose to use some with the content material on my weblog whether or not you don’t mind. Natually I’ll give you a link in your net blog. Thanks for sharing.

As a hint, if you do this with 11.04 rsyslog will go haywire and consume 100% CPU as it fails to log kernel messages. Stop and/or fix kernel logging in rsyslog.conf.

Comment on How to Create your own ‘DynDNS’ Service by Apo

Apo — Thu, 24 Nov 2011 09:13:08 +0000

If you’re using pppd, you can just create an executable file in your pppd’s ip-up.d folder (in my case that’s /etc/ppp/ip-up.d), or edit the ip-up script.

Contents of my /etc/ppp/ip-up.d/60-dyndns:

#!/bin/sh
nsupdate -k /etc/nsupdate/named.private << EOF
server
zone
update delete foo.zone. A
update add foo.zone. 60 A $4
send
EOF

pppd will run the ip-up script every time you get a new IP, so you don’t have to poll your interface every minute.

There’s also a patch for ddclient to run nsupdate, but that’d mean that you have to disable updates in your package manager, so meh.

Comment on How to DSL and UMTS Failover on OpenBSD by Igor

Igor — Wed, 19 Oct 2011 15:50:50 +0000

Dear Chris,
I’m trying to do something simular on an Alix6e1 board from Pcengins and an ICON 225 netstick from Option.
I want to make a router that uses UMTS connection to back up a Cable connection(L2TP) and I want the Cellular usage to be minimal.
I have OPENBSD 4.9 installed on my board, could you guide me on hot to set up the two connections, how to set the dialup- where the ralevant system file are located.
I’m a bit new to openbsd and unix in general but I want to learn and I’d apriciate your help.
I saw your post on “How to OpenBSD with Huawei E1750 UMTS” but as I’m new to it- it’s a bit Chinese for me- if you could eleberate on the steps needed to setting up the system.
To make things simpler I want to start by puting a router infront of my box so I will not need to dial up a landline connection and will only need to deal with the UMTS dial up.

Hi, if you look at the line Chris posted you might need to change “/Developer-old..” to “/Developer-3.2.6…”

Chris, thanks!

Well, I followed the suggestion when upgrading from Xcode-3.2.6 to Xcode-4.1. But something went wrong: after issuing the command
sudo /Developer-3.2.6/Library/uninstall-devtools –mode=all
also Xcode-4.1 was broken: for instance, the make command disappeared, and in my App Store page the Xcode lists as not installed. Hopefully installing it again will fix the issue … I’ll know in a few hours, since I’ve to download it again.

It will break everything that has dependencies on Xcode 3.

I ran that command, and it broke a bunch of command line stuff. I’m probably going to have to redownload the Xcode 4 installer to fix this.

Hey mate, Cheers for this. I’ve taken this one further by keeping the functionality but moving the backup over to my secondary HD. What I did was copy the sleepimage over to my 2nd HDD then disable the Local backup, create a symlink from the root of my SSD to the 2nd HD where I copied the .MobileBackups folder to then re-enabled the Local Backup.

Hey presto, we have the benefit of the Local Backups without consuming the precious SSD space

No. I sold my Vertex 2′s because of all these issues. Also, I haven’t figured out how to upgrade the Firmware on a Mac!
There are a few tricks as far as I remember, but really? Just ignore the Vertex2. I’m currently testing the Vertex3 and will post my results in a few days.

To make it short: get an intel if you want reliablility.

Hi there! I’m just thinking about buying an OCZ Vertex 2 120gb (OCZSSD2-2VTXE120G) for my MBP 13″ 2010(2.4).
I have seen on the OCZ page that their firmware got updated since your post(now its 1.33). Can You please tell me if you upgraded to last firmware and if yes, of you still have any problems?
Thank you so much.
Kind regards

I’m still totally happy with the Intel. Can’t tell you about Garbage Collection on the OCZ tough.
