Fritz!Box VPN error messages – via: VPN mit der FritzBox :: network lab

Posted by jpluimers on 2015/11/02

VPN mit der FritzBox :: network lab has a nice walk through on how to set up non LAN-LAN VPN connections with Fritz!Box.

But the really cool thing is that they have a table of IKE (Internet Key Exchange) error messages.

Until now, I mainly had these errors, which thanks to the table now have a description:

Better than

Note: both are within the public IP range, so not in the ranges mentioned here: Identifying the address range of the IPv4 address for the Internet connection | FRITZ!Box 7390 | AVM International.

Maybe I should just use the Windows tools to setup the config: MarkusKirschmann.de – Blog » IKE-Error Ox1c.

network, multicast and send address in TransportNetwork; via Digging into Tibco Rendezvous network details – II

Posted by jpluimers on 2015/10/28

Tibco is very powerful and can do all sorts of casting.

For my memory (formatted for readability; there are more details at OpenPGM Concepts : Transport):

The network parameter consists of up to three parts, separated by semicolons—network, multicast groups, send address—as in these examples:

Example Meaning
lan0 network only
lan0;225.1.1.1 one multicast group
lan0;225.1.1.1,225.1.1.5;225.1.1.6 two multicast groups, send address
lan0;;225.1.1.6 no multicast group, send address

The format is like this:

partOne;partTwo;partThree

and some bits are optional

partOne[;[partTwo][;[partThree]]]

Part one identifies the network, which you can specify in several ways: – Host name, Host IP address, Network name, Network IP number, Interface name, Default TRDP daemons use the network interface which corresponds to the hostname of the system as determined by the C function gethostname(). PGM daemons use the default PGM multicast interface, 224.0.1.78.

Part Two—Multicast Groups – Part two is a list of zero or more multicast groups to join, specified as IP addresses, separated by commas. Each address in part two must denote a valid multicast address. Joining a multicast group enables listeners on the resulting transport to receive data sent to that multicast group.

Part Three—Send Address, Part three is a single send address. When a program sends multicast data on the resulting transport, it is sent to this address. (Point-to-point data is not affected.) If present, this item must be an IP address—not a host name or network name. The send address need not be among the list of multicast groups joined in part two. If you join one or more multicast groups in part two, but do not specify a send address in part three, the send address defaults to the first multicast group listed in part two.

Note: I wasn’t aware that for Tibco Rendezvous the default multi-cast network was 225 (often you see 224 here, as that is the starting multi-cast range in the IANA IPv4 Address Space list)

Fiber to Fiber speed beats Cable to Fiber speed by a factor 2 (all three internet connections are in the same house)

Posted by jpluimers on 2015/10/05

I’ve two fiber connections, one cable connection and one ADSL connection at home.

This is a traceroute from one fiber connection to the other over the outside network:

This is the same but from my third connection (that will go away sooner than later): Cable.

Finally there is ADSL (which will go even sooner):

 5  snip.xs4all.nl (80.100.143.119)(N!)  15.914 ms (N!)  16.171 ms (N!)  15.710 ms

Cable is about twice as slow than Fiber.

ADSL is about three times as slow than Fiber.

ICA client keyboard shortcuts

Posted by jpluimers on 2015/09/07

Too bad the Citrix Receiver remaps the keyboard shortcuts in a way that keyboards without a numeric keypad is a pain.

First of all, it was a bit tough to find the shortcuts, and I have not found a way to modify them.

Here is what I did find:

http://169.254.1.1 trick for Opening UI of the FRITZ!WLAN Repeater 1750E – via: AVM International

Posted by jpluimers on 2015/08/24

Because http://fritz.box points to my Fritz!BOX router, it cannot be used to get to my Fritz!WLAN Repeater. I just learned about the http://169.254.1.1 trick does.

Which saves me from remembering the repeater IP-address or name.

Setting your DNS servers manually – via – Tweakers

Interesting Dutch thread about a major ISP having DNS issues because of DDos attacks. Many messages to set your DNS servers manually on various operating systems, and a list of good DNS server alternatives. Recommended reading:

YouTube: Some windows shortcut key hints (by Alister Christie)

Posted by jpluimers on 2015/06/29

I wrote quite a few entries about Keyboards and Keyboard Shortcuts.

But Alister Christie did something much better: he published a great video on YouTube: Some windows shortcut key hints.

Most of the examples he shows work in Windows 7 and up.

TinkerTry’s Xeon D-1540 fueled ESXi 6.0 home lab build begins LIVE! | TinkerTry IT @ Home

Posted by jpluimers on 2015/06/26

Interesting machine: TinkerTry’s Xeon D-1540 fueled ESXi 6.0 home lab build begins LIVE! | TinkerTry IT @ Home.

It does ECC and IPMI, fits mSATA, 2.5 drives, and 3.5 hot-swap bays. For more specs see Supermicro SuperServer mini-tower ordered with 64GB of memory for $1900 starts the ultimate 24×7 home virtualization lab | TinkerTry IT @ Home.

The drive trays used are these:

Besides the official ways of converting the 3.5″ tray for 2.5″ drives that only allows for 4 drives to be converted, I think there is an unofficial way that allows for more hot-swappable 2.5″ drives.

Converting the unofficial way

The case is an CSE-721TQ-250B. Looking at a picture of the dimensions of the space where the drive trays fit in (thanks Anandtech), removing the CSE-SAS-733TQ backplane and fitting these into the MCP-220-00075-0B should allow for 8 2.5″ drives to be connected:

(all found via Sata Rack Enclosure – on Aliexpress.com)

Converting the official way

Modify an existing 3.5″ tray to fit a 2.5″ drive: please note the drive is mounted up side down!

Note there is another (dual!) 2.5″ tray for a different kind servers: many 2U and some 4U rack mounted SuperMicro servers and chassises optionally have this in the back for boot drives:

These are for instance used in the below chassises and SAS extenders based on them (the extenders all use SFF-8644 HD mini-SAS3 cable connectors):

Note to self: if ever getting these, ensure to get them with PWS-920P-SQ or better power supplies as these are super quiet although the chassis fans can be loud which can be resolved with a PWM controller or carefully selecting the SuperMicro parts from Supermicro | Support | System Fan Matrix as described in Supermicro noise levels | ServeTheHome and ServeThe.Biz Forums.
