Pour synchroniser un répertoire et son distant sans le git :

rsync -avirzh --exclude '.git' . <destserver>:~/path/to/dest
rsync -avirzh -e 'ssh -p 2222' . root@IP.IP.IP.IP:~/path/to/dest

With partial, progressive a restart on error :

rsync -Pavirzh -e 'ssh -p 2222' . root@IP.IP.IP.IP:~/path/to/dest

Short explanation :
-P : retry a long transfer that may be interrupted.
-a, --archive : a quick way of saying you want recursion and want to preserve almost everything (also include -r)
-v, --verbose
-i, --itemize-changes : show changes
o A < means that a file is being transferred to the remote host (sent).
o A > means that a file is being transferred to the local host (receive).
o A c means that a local change/creation is occurring for the item
o A h means that the item is a hard link to another item (requires --hard-links).
o A . means that the item is not being updated
o A * means that the rest of the itemized-output area contains a message (e.g. "deleting").
o A s means the size of a regular file is different and will be updated by the file transfer.
o A t means the modification time is different and is being updated to the sender’s value
(requires --times).
o A p means the permissions are different and are being updated to the sender’s value
(requires --perms).
o An o means the owner is different and is being updated to the sender’s value (requires
--owner and super-user privileges).
o A g means the group is different and is being updated to the sender’s value (requires
--group and the authority to set the group).
o The u slot is reserved for future use.
o The a means that the ACL information changed.
o The x means that the extended attribute information changed.
-r, --recursive
-z, --compress
-h, --human-readable

Construction des configurations SSL

Dans mon cas (partage temporaire windows / linux) :

setsebool -P samba_export_all_rw=1

Calculateur de Masque IPv4
Tout est dans le titre.

Mapping IANA / OpenSSL :

TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 / ECDH-RSA-AES128-SHA256

Tel qu'utilisé sur https://www.ssllabs.com/ssltest

Supprimer une ip virtuelle (ou pas !)

 sudo ip addr del 10.0.100.1/28 dev ens160

Parce que certains client VPN supporte le proxy seulement sous Windows.... (coucou NetExtender !)

proxychains netExtender bla bla

C'est beau Linux.

Parce que j'oublie tout le temps :

dig shaarli.hoab.fr @8.8.8.8

Et pour suivre la propagation DNS, exemple : https://www.whatsmydns.net/#A/mangrove.finalpledge.fr

Test if user is not able to open a shell or login
Petite commande pour savoir si un user a accès à un répertoire.

sudo -u www-data ls /home/user

Une bonne information sur le lastlog, c'est un sparse file : la taille affichée n'est pas la taillé réellement consommé.
Seuls les blocs réellement utilisé sont consommés.

du -h /var/log/lastlog
du -h --apparent-size /var/log/lastlog
ls -lsh /var/log/lastlog

Quand la machine est connecté à un AD avec plusieurs milliers d'entrées....

Pense bête routing :

route -n
route add -net 10.0.101.0 netmask 255.255.255.0 gw 12.34.56.1
route add -net 10.0.100.0 netmask 255.255.255.0 gw 12.34.56.1
route delete -net default gw 12.34.56.1
route del -net 192.168.100.0 gw 12.34.56.1 netmask 0.0.0.0 dev eth0
route add -host 98.76.54.32 gw 12.34.56.1

IP route

ip route show
ip route del default via 12.34.56.1 dev ppp0 scope link
ip route add 10.0.0.0/1 via 12.34.56.1 dev ppp0 scope link
ip route add 10/1 via 12.34.56.1 dev ppp0 scope link
ip route add 10.0.0.0/16 via 12.34.56.1 dev ppp0 scope link

Voir si il y a des données en transfert

cat /sys/block/<dev>/stat
watch grep ^Dirty /proc/meminfo
