Microsoft Teams and Join Link problem

/ Linux /

I’ve recently upgraded Microsft Teams to version 1.4.00.4855 (I run it on openSUSE Linux but I think this problem can be related to the rpm build and maybe even the deb) basically the external Join Invite by URL stopped working.

Digging around in the browser the content-type: "msteams" it’s opened by the lanucher "/usr/bin/teams" luckily it’s a simple shell script, apparently they added some switch messing up the URL variable.

Following the explanation, I’ve just downloaded the rpm and unpacked it:

https://packages.microsoft.com/yumrepos/ms-teams/teams-1.3.00.958-1.x86_64.rpm 
https://packages.microsoft.com/yumrepos/ms-teams/teams-1.4.00.4855-1.x86_64.rpm
rpm2cpio teams-xxxx.x86_64.rpm | cpio -idmv

And then do some diff:

leo@thinkleo5:~/dev/teams> diff 1.3/usr/bin/teams 1.4/usr/bin/teams
11c11
< nohup "$TEAMS_PATH" "$@" > "$TEAMS_LOGS/teams-startup.log" 2>&1 &
---
> nohup "$TEAMS_PATH" --disable-namespace-sandbox --disable-setuid-sandbox "$@" > "$TEAMS_LOGS/teams-startup.log" 2>&1 &
leo@thinkleo5:~/dev/teams>

Teams still run but the URL joins are ignored, you can fix editing the "/usr/bin/teams" the line 11 of the launcher.

From:

nohup "$TEAMS_PATH" --disable-namespace-sandbox --disable-setuid-sandbox "$@" > "$TEAMS_LOGS/teams-startup.log" 2>&1 &

To:

nohup "$TEAMS_PATH" "$@" --disable-namespace-sandbox --disable-setuid-sandbox > "$TEAMS_LOGS/teams-startup.log" 2>&1 &

Hyperlapse Experiment 1

/ Creative /

Some years ago (I think in 2017) I wanted to try to make a hyper-lapse video this is the result:

Some technical details:

  • I’ve moved for 5 meters
  • On every frame, I move by 5 centimetres forward
  • I’ve taken about 100 frames
  • The final video it’s created using FFmpeg

This is the FFmpeg script used to create the final clip:

ffmpeg -r 30 -pattern_type glob -i '*.JPG' -c:v libx264 -pix_fmt yuv420p out30fps.mp4

JunOS Upgrade

/ Networking, Tech /

For some reason, JunOS 12.1X46-D65.4 on SRX platform can’t validate any update it takes me several attempts before figure out to run the upgrade with the “no-validate” option.

Video Router XY Web Panel

/ Broadcasting /

From the moment that I’ve started working for a broadcaster I was immediately fascinated by the video routers, they basically are the core of a production centre the can switch, sync a reclock SDI signals it’s a very simple concept if you think switch a video from one port to others, but they hide a very complicated implementation because since you can switch any source to any destinations in the routing matrix the hardware must be no-blocking and you can’t do bandwidth oversubscription; in the meantime, you’ve to keep the vertical interval synched to avoid frames losses that cause flickering or other unexpected behaviours.

I know everything in the world it’s transitioning some sort of IP/Networked signal, but as I’ve mentioned before with 2022/2110/NDI/SRT you’ll always end up choosing the wrong one, this is the reason why I consider the legacy way more interesting, and there is nothing more legacy than the SDI born in the late ’80 it’s still surviving and actively developed. None I can say about the video routers and their ecosystems still based on some sort of not so fancy control protocol over some sort of serial interface.

To cut short a crosspoint commands it’s made by 3 elements: a destination, a source and a level; the first two are pretty self-explanatory, the level it’s the media type, in the big an complex systems, for example, you can split audio, video and data into different matrixes or different modules and control everything from a single command.

RCP XY PanelsHere we come to the reason for this project, some time ago I’ve acquired some video router to build my studio at home I’ve ended up acquiring a lot of 5 8×8 HD/3G routers and 1 8×8 SD (this one literally catch fire, but this is a story for another time, I’ve managed to save the 5 3G) I quickly realise the problem was not to find the matrix itself but to find the control panels, so why not to do a little reverse engineer and build write something.

 

 

 

Panacea Back Panacea Front

My weapon of choice for this project is the Leitch / Harris / Imagine Communications branded Panacea video router, this kind of devices are in my opinion very consistent XY protocol (in different flavours) the same code that I’ve written for a device released in early 2000 (Panacea/XPlus) can still run on every modern Imagine platforms like the Integrator or Platinum.

Imagine Communications devices are managed via XY Protocols, even if the name is similar between them they behave in a very different way.

  • XY Terminal (the crosspoint commands are specified in multiple lines via RS232 variables are decimal numbers)
  • XY Telnet (same as the XY Terminal but via Telnet)
  • XY Serial (the crosspoint command is a single string and every serial or telnet connection are joined to a shared stream where you can read every session and send commands, variables are hex)
  • XY Client (the router open a session to a client but I’ve never figured out how the handshake works)

You can find an example of XY Terminal and XY Serial code at https://github.com/lrizzi/xy-panel the python web services act as an API gateway, the web pages are a simple frontend.

Getting back?

/ Life /

I know, it’s been a while since a wrote somethings, at the time 2014 (to be precise I’ve found a very incomplete draft from 2015) the blogs were still cool, nowadays everything it’s compressed in a few words on some social media platform of choice like we don’t have any more time to stop read and truly understands what are we reading. And it’s a kind of a shame if you think how we devolve since 10 years ago, maybe it’s been more, much more, but at the time I didn’t have the proper knowledge to understand what’s really was going on in the world.

Anyway, I think it’s the right time to get back to write, since the last post I’ve founded two companies, and at this precise moments, you understand the importance of visualizing and making something new from scratch instead of trying fix someone else chronically broken stuff. This doesn’t mean it’s an easier task quite the opposite I found myself very far from my comfort zone more times than I’ve expected and dealing with it was really hard.

I’ve also shifted my work interest from the legacy enterprises to the Media industry: Television to be specific, and even if broadcasting isn’t something new for me I truly discovered a new world for my mind, but this is a story for another time!

As I wrote in some previous posts I’ve replaced my old thinkpad with a new one, the deal was to find a Linux operating system with a full support of my hardware. I just tried to migrate my trusty Redhat 6, and after some rebuild I get a “well” working system.
I love the legacy system you can always know where to find the things you need and generally they works more better than new one, but for desktop use sometimes is necessary something a little modern (kernel, lib, etc.).

So I’ve installed Fedora 19, I already used this distribution in the past till version 14 (the last release with Gnome 2), the installer is great and after reboot surprise, my notebook hardware are fully supported even HSPA/GPS card, fingerprint reader and TPM chip, awesome!!
At this point the problem begin.. and the name is Gnome 3, Shell or whatever they wanna call that crap, I even found a very disappointed twit dated 11/06/11 wrote by me about that, when I’ve tried Fedora 15 for the first time and the complaints were to Gnome 3..
By the way I decided to give it a chance, I spent 2 days, days of terrific pain, patch and random code to fix bugs (or trying to do) just for made it a little usable and finally I figured out: after more than two years still is a bunch of buggy crap.

I can only describe it as The worst user experience ever, I don’t want a stupid smartphone/tablet or clone of clone of clone of other worst user interfaces.

So I took a look of alternatives and I’ve tried Xfce: it’s light, simple and stable.

The next post will be related to the optimization and integration of Xfce.

Telecom Italia – IPv6 Pilot on Cisco

/ Cisco, Networking /

To my amazement, Telecom Italia released a pilot project of IPv6 deployment on residential/dynamic ip only adsl internet access, but on theirs support site there’s configuration only for some useless systems. So, I’ve decided to write a configuration for Cisco platform.

Usually the typical Telecom Italia PPPoE or PPPoA ADSL connection with dynamic IPv4 only was authenticated with “aliceadsl” as user and password, now with bran new credential along IPv4 the endpoint router advertise a IPv6 /64 class (always dynamic).

username: adsl@alice6.it
password: IPV6@alice6

And now IOS configuration:

– ATM inteface:

interface ATM0/0/0
no ip address
atm restart timer 300
no atm ilmi-keepalive
dsl operating-mode auto
hold-queue 100 in
!
interface ATM0/0/0.1 point-to-point
pvc 8/35
vbr-nrt 380 380
oam-pvc manage
encapsulation aal5mux ppp dialer
dialer pool-member 1

– Dialer inteface:

interface Dialer0
mtu 1492
ip address negotiated
ip nbar protocol-discovery
ip flow ingress
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
ipv6 address autoconfig
ipv6 enable
no cdp enable
ppp authentication chap callin
ppp chap hostname adsl@alice6.it
ppp chap password 0 IPV6@alice6
ppp pap sent-username adsl@alice6.it password 0 IPV6@alice6

– Route configuration:

ip route 0.0.0.0 0.0.0.0 Dialer0
ipv6 route 2000::/3 Dialer0

You can check with following command:

route01#sh ip int brief | sec Dialer0
Dialer0                    XXX.XXX.XXX.XXX    YES IPCP   up                    up
route01#sh ipv6 int brief | sec Dialer0
Dialer0                    [up/up]
FE80::1
2A01:2003:xxxx:xxxx::1

You can discover your /64 assigned class with:

route01#sh ipv6 int di0 | sec Global
Global unicast address(es):
2A01:2003:xxxx:xxxx::1, subnet is 2A01:2003:xxxx:xxxx::/64 [PRE]
valid lifetime 2591993 preferred lifetime 604793
route01#

I’ve left out NAT and other further configuration.

Update: prefix delegation

Remote Desktop Licensing service to fail to start

/ Daemon /

Remote Desktop Licensing service to fail to start, with error code %%-1073672191.

The Terminal Services Licensing service cannot start. The following error occurred: Can’t initialize Cryptographic – error code 5.

Sometime happens a problem with Remote Desktop Licensing services not starting.
The Terminal Licensing MachineKeys have permissions for Administrators and/or TermServLicensing  but the service starts using the “Network Service” account… Why??????

You can fix the problem adding Network Service account (read only privileges it’s ok), on follow directory (you can force ownership propagation for reapply the correct privilege tree):

C:\Documents and Settings\all users\Application Data\Microsoft\Crypto\RSA\MachineKeys

Then the service start, correctly.

 

For further information you can take a look at microsoft KB:

Recovery HFS partition table

/ Mac OS X /

First think, scan your damage disk with a tool like “testdisk” (http://www.cgsecurity.org/wiki/TestDisk) look for lost partitions, unfortunately HFS is not fully supported by this great tool, then you need to use pdisk or other partition software.

2. edit: /etc/sysconfig/network
HOSTNAME=srv03.mil11.wide-net.org

3. past into kernel new hostname
echo "srv03.mil1.wide-net.org" > /proc/sys/kernel/hostname

Or

sysctl kernel.hostname=srv03.mil1.wide-net.org

Consider a restart net services /etc/init.d/network restart but is not strictly required.

AirOS – Rate Algorithm

/ Tech /

Rate Algorithm: defines data rate algorithm convergence:

Optimistic Algorithm is aggressive enough to move to a higher rate but yet tries to conservatively capture the fluctuations of the RSSI. It starts with the highest possible rate and then decreases till the rate can be supported while periodically transmitting packets at higher rates and computing the transmission time. The optimistic rate algorithm always looks to achieve highest throughput while sacrificing noise immunity and robustness.

Rate Algorithm selection
Conservative Algorithm is less sensitive to individual packet failure as it is based on a function of number of successful and erroneous transmission/retransmission over a sampling period. It steps down to a lower rate after continuous packet failure and steps up after number of successful packets. The conservative rate algorithm provides the best case stability / robustness, but may compromise maximum throughput. It is recommended to select conservative rate algorithm when the signal strength is low due to noisy environment or link distance.

EWMA Algorithm is trying to move to a higher rate but is continuously monitoring the packet failure counters. The Exponential Weighted Moving Average (EWMA) Algorithm (also known as minstrel) is a hybrid of the Conservative and Optimistic Algorithm. It is the compromise for most of the wireless network use cases.

Linux – IBM LinTape driver

/ Linux /

If you need to user ibm lto tape drive inside IBM, Adic, Dell tapelibrary, with Tivoli Storage Manager is necessary to use

Download latest driver from IBM Fixcentral:
Storage Systems => Tape Systems => Tape device drivers and software => Linux

Get two two RPMs (my system is an RHEL 5 on 32bit hardware) :
lin_tape-1.61.0-1.src.rpm <== Kernel module
lin_taped-1.61.0-rhel5.i386.rpm <== Binary services

First step, rebuild the source:

# rpmbuild --rebuild lin_tape-1.61.0-1.src.rpm

Installing lin_tape-1.61.0-1.src.rpm
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.625
+ umask 022
+ cd /usr/src/redhat/BUILD
+ cd /usr/src/redhat/BUILD
+ rm -rf lin_tape-1.61.0
+ /bin/gzip -dc /usr/src/redhat/SOURCES/lin_tape-1.61.0.tgz
[cut]
Wrote: /usr/src/redhat/RPMS/i386/lin_tape-1.61.0-1.i386.rpm
Executing(%clean): /bin/sh -e /var/tmp/rpm-tmp.18792
+ umask 022
+ cd /usr/src/redhat/BUILD
+ cd lin_tape-1.61.0
+ rm -rf /var/tmp/lin_tape-1.61.0-1-root-root
+ exit 0
Executing(--clean): /bin/sh -e /var/tmp/rpm-tmp.18792
+ umask 022
+ cd /usr/src/redhat/BUILD
+ rm -rf lin_tape-1.61.0
+ exit 0

Second step, install all:

# rpm -Uhv /usr/src/redhat/RPMS/i386/lin_tape-1.61.0-1.i386.rpm
# rpm -Uhv lin_taped-1.61.0-rhel5.i386.rpm

Last step, start service and check for the probed devices:

# /etc/init.d/lin_tape start

# cat /proc/scsi/IBM*

[leo@thinkleo2 ~]$ /usr/lib/ICAClient/wfcmgr -icaroot /usr/lib/ICAClient
Warning: Missing charsets in String to FontSet conversion
Warning: Missing charsets in String to FontSet conversion
Warning: Unable to load any usable fontset
Error: Aborting: no fontset found

Solution 1 force language C (my favourite for any lang problems):

[leo@thinkleo2 ~]$ export LANG=C

Solution 2 remove charset cjkuni:

[leo@thinkleo2 ~]$ sudo yum remove cjkuni*
