If as me you have EVE-NG (2.0.3) and lab some Cisco XRV9K-Full on a virtualized box running AMD Ryzen processor, you have probably encountered problem to start the image. After reading lot of website, it seems the answer is change the command line.

My original command line is :

-enable-kvm -smbios type=1,manufacturer="cisco",product=\"Cisco IOS XRv 9000\",uuid=[...] -cpu host

I correct to :

-enable-kvm -smbios type=1,manufacturer="cisco",product="Cisco IOS XRv 9000",uuid=[...] -cpu qemu64,+ssse3,+sse4.1,+sse4.2

For one time this blog post will not be around Telecom and Cisco/Juniper/Nokia or something like this.

Just to keep in mind how to replace a faulty device in a ZFS pool.

I have :

root@pve:~# zpool status -x
root@pve:~#  zpool status
  pool: pve-zfs
 state: DEGRADED
status: One or more devices could not be used because the label is missing or
        invalid.  Sufficient replicas exist for the pool to continue
        functioning in a degraded state.
action: Replace the device using 'zpool replace'.

But how to replace this faulty device when all the howto on the net talk about replace/make offline the old disk… But in my situation I have made an RMA on the disk and don’t have mind to make the faulty device offline.

I am happy to share that I have achieved something that could be normal as usual but important to me : use different vendor in certification tracks.

I have passed JNCIA-Junos.

For the annuary musical amateur festival in all roads and cities of France, my prefered song :

Sorry for me music stops in April 5, 1994. Perhaps I have not enough searched on jamendo or independant scene. I don’t have ever found a music with all this primitive energy I can feel with Nirvana music. Maybe life should have stopped in the 90s, it would have been better considering all the shit that we can see, live, with all these media, this escalation in the presence on social networks. What would Kurt think living in 2022? I know this post is in that movement. I only ever wrote on this rag to share my bullshit, my feelings and hacks on free systems (BSD my love come here :-)) that I have been around since 1997.

Perhaps it seems easy for you, but it was not for me at begining even if I am running bind9 master/bind9 slave already.

We will begin with TSIG key, on your master DNS server :

root@Sagitarius:~# tsig-keygen mykey > /etc/bind/keys/mykey.key
root@Sagitarius:~# cat /etc/bind/keys/mykey.key
key "mykey" {
        algorithm hmac-sha256;
        secret "+OyXk+FYgsnE6Lei59Qi2LPsctRHPaqcYRpftG4YXKk=";
};
root@Sagitarius:~# 

Now we will configure this on my “named.conf.local” file as :

root@Sagitarius:/etc/bind# cat named.conf.local 
[...]
//On indique la clé à utiliser et son algorithme de chiffrement
include "/etc/bind/keys/mykey.key";

//On indique l'adresse IP du serveur "Esclave"
server 192.168.1.81
{
        keys { mykey; };
};
[...]
zone "my-blah-zone.fr" {
       type master;
       file "/etc/bind/my-blah-zone.fr.zone";
       allow-transfer { 192.168.1.81; key mykey; };
       notify yes;
};
[...]

Ok. last command :

If you are newbie snmpb user. I used snmpb mib brower to check accros some SNMPv3 IOS XR config, you can be faced to :

You must only right click to white window such as :

That’s it ! Have fun…

If you are familiar with IOS XR and JunOS, it lacks a rollback to IOS and IOS XE. You can do it with “archive” such as :

1. Configure where your archive will be stored.
2. Say to your OS to “archive” at a point
3. Configure your router with a “revert timer”
4. Confirm if it is ok for you

Here we go in details now :

1. Configure where your archive will be stored.

Router# conf t
Router(conf)# archive
Router(conf-archive)# path bootflash:myconfig
Router(conf-archive)# maximum 10
Router(conf-archive)# end
Router# wr

2. Say to your OS to “archive” at a point

Big news : le 20 décembre, à 21h, l’aventure @time for the planet (dont je suis associé), change de dimension.

Il y a bientôt 2 ans, Time for the Planet prenait vie à partir de rien, autour d’une ambition un peu folle : 

créer un immense mouvement citoyen non lucratif pour rassembler progressivement 1 milliard d’euros afin de déployer 100 innovations majeures et open source partout dans le monde, capables de nous aider à décarboner massivement nos sociétés.

Simple and efficient, two traceroutes from sin02(singapore) and nrt01 (?) :

For now I will not move from this blog motor, but I have tested bashblog because I have made some search of my really old blog post and it make me think about nanoblogger which is not ever maintained now. So I search only for curiosity if there is now this kind of project. Bashblog is this kind of work. Only some bash and a quick result.

It is simple, just configure EDITOR variable and let’s go :
