Jumbo Frame !

J'ai récemment remplacé mon serveur (une grosse tour avec plein de disques dur - 250 Go je crois - en RAID5) par un NAS de 1,5 To en RAID1. Pour faire office de serveur j'ai récupéré un vieux PC portable (Dual Core 1.6 GHz quand même, merci Manu ;) que j'ai installé sur un switch gigabit à côté du NAS. Par contre le portable n'avait pas de carte réseau gigabit, ce qui était bien dommage car le NAS en possédait une. J'ai donc acheté une carte PCMCIA gigabit avec un chipset Realtek (trouvée sur eBay, j'ai privilégié une carte avec un chipset connu =) et je l'ai pluggée. Je me suis mis en quête d'un outil pour tester la connexion portable <-> NAS, j'ai trouvé l'utilitaire iperf :

~$ sudo apt-get install iperf
Démarrage en mode serveur sur le NAS
~$ iperf -s -i 5 -m -w 200k
Démarrage en mode client sur le portable
~$ iperf -c <IP du NAS> -f m -i 5 -p 5001 -t 60 -w 200k
Ne pas oublier d'ajouter une route statique pour forcer l'utilisation de la carte gigabit
~$ sudo route add -net <IP du NAS> netmask <netmask de l'IP du NAS> gw <IP de la carte gigabit> dev <ID de la carte gigabit>
Et surtout forcer le paramètre MTU pour activer les "Jumbo Frame" (qui permettent de transférer des plus gros paquets. La valeur (ici 7200) est fonction de votre carte réseau et du driver. Si la valeur n'est pas supportée vous aurez un message du genre "SIOCSIFMTU: Argument invalide".
~$ sudo ifconfig <ID de la carte gigabit> mtu 7200
Du coup voilà les stats avant :
~$ iperf -c <IP du NAS> -f m -i 5 -p 5001 -t 60 -w 200k

  • Flickr Filter options. expand / collapse
    Insert a Flickr photo. A working example:
    • [flickr-photo:id=7357144724, size=m, mintitle=999, minmetadata=999] (accepts only the parameters id, class, style, size, mintitle and minmetadata)
    To float single photos use [flickr-photo:id=9247386562, class="floatright"], [flickr-photo:id=9247388074, style="float:left;"] or use the AutoFloat module (recommended).

    Insert a Flickr album. Working examples:
    • [flickr-photoset:id=72157634563269642, size=s, num=8, tags=kids/men, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]
    • [flickr-gallery:id=72157648989290536, size=q, num=4, sort=views]
    • [flickr-group:[email protected], size=q, num=8, tags=flowers, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]
    • [flickr-user:id=lolandese1, size=q, num=6, tags=kids/men, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]
    • [flickr-user:id=public, size=q, num=10,tags=Augusto Canario, filter=interesting, sort=views, extend=true]
    • [flickr-user:id=public, size=q, num=8,location=48.867556/2.364088, date=2015-01-11, filter=interesting, sort=views]
    • [flickr-favorites:id=lolandese, size=q, num=4, tags=tomosborn/people, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]

    Common sizes:
    s : small square 75
    t : thumbnail, 100 on longest side
    q : big square 150
    m : small, 240 on longest side
    n : small, 320 on longest side
    - : medium, 500 on longest side
    x: Responsive slideshow (for group, set and user IDs only)
    y: Basic responsive slideshow (for set and user IDs only)
    The 'c' size (800px) is missing on Flickr images uploaded before March 1, 2012. Photos with non existing sizes will be skipped in albums.

    TIP: Not only the node body but also blocks make use of a text format. Build your own custom Flickr album block using the Flickr Filter syntax.

    PARAMETER EXAMPLES. Omitting a parameter will result in the default value to be used.
    id=lolandese1 : A photo, set, user or group ID. id=public grabs CC licensed public photos (only for [flickr-user:...]). Default: id=k4cy (set in config).
      Find a Flickr group ID. Valid ID values: numeric ID (the one that contains a '@'), path alias, Flickr username or the user's email.
    class="floatleft foo bar" : Syntax as in HTML. Wrap the value in quotes (or not) and put spaces between multiple classes.
      Applies to the outer HTML element of a photo or album.
    style="float:left; border:solid 2px;" : Syntax as in HTML. Wrap the value in quotes (or not) and put semicolons between different style declarations.
      Applies to the outer HTML element of a photo or album.
    size=q : Big square (150px). The sizes x and y display a slideshow and ignore number, media, tags, location and sort settings.
      Default single photo: size=m, album photo: size=s (both set in config).
    num=4 : Display 4 photos. Default: num=30 (set in config). For albums only.
      If set to 1, the single image will behave as such. Heading and counter will be omitted, and float might apply.
      Used to display a single changing random or recent image.
    media=all : Display both photos and videos. Default: media=photos. For albums only.
    tags=kids/men : Separate multiple tags with a slash (/). Display all set, group or user photos that contain the indicated tags.
      Case insensitive, matches any tag, for photosets and galleries even partial. You can exclude results that match a term by prepending it with a - character.
      Public albums will only display photos that match all tags. Like on Flickr spaces are removed from tags (e.g. 'Victoria park' becomes 'victoriapark').
      For albums only.
    extend=true : Extend the tag filter to search for matching terms also in the Flickr photo title and description besides Flickr tags.
      Default: extend=true (set in config). For albums only.
    tag_mode=all : Matches 'all' defined tags (AND). The other possible value is 'any' (OR).
      If this parameter is omitted, 'all' is used if no Flickr user ID is known (public search), otherwise 'any' is used. For albums only.
    location=48.85837/2.294481/0.2 : Display photos within 200 mt from the Eiffel Tower. Lat/lon/radius (in km). Separate values with a slash (/).
      To get the coordinates for a location, right-click on a Google map and choose 'What's here?' or copy/paste it from the URL.
      Substitute the comma (,) with a slash (/). Optionally add a radius to force a major number of results to filter on (max. 32 km).
      If the radius is omitted it defaults to 14 meter and gradually expands to 32 km until a sufficient number of results are returned.
      Besides decimal coordinates also degrees are accepted, e.g. 2° 21' 50.72". For user and group albums only, also public.
    date=2015-01-11 : Display photos taken on 11 January 2015.
      Many accepted date formats (e.g. '11 Jan 2015'), also relative formats (e.g. 'first day of last month | last day of last month').
      Separate two date values with a vertical bar (|) to cover a timespan of multiple days. For user and group albums only, also public.
      Tip: Use a date in combination with a location to grab public photos of an event.
    heading=h3 : Wraps the album title in HTML tags. Use 'p' to apply no style or 'none' to suppress the title. Default heading=p (set in config). For albums only.
    sort=views : Display the most viewed Flickr photos first (popularity, slower response after cache clear).
      Other values: unsorted = recent as delivered by the Flickr API (fastest response),
      random (slower response after cache clear), taken (newest first), posted (newest first) , added (for groups only, newest first) and id (on photo ID, newest first).
      Default: sort=unsorted. For albums only.
    filter=interesting : Display the most interesting photos. Other possible value: relevant. For user and group albums only, also public.
    count=false : Suppress display of the counter under the album (e.g. 5 out of 124 on Flickr). Default: count=true (set in config). For albums only.
    mintitle=999 : Suppress display of the title in the photo captions for images below a width of 999 px. Default: mintitle=100 (set in config).
    minmetadata=999 : Suppress display of the metadata in the photo captions for images below a width of 999 px. Default: minmetadata=150 (set in config).
