cFosSpeed - All SPD commands

spd sethops

With the command sethops you can set the ttl value of the cFosSpeed measure pings. Just set the number i for the value. The output is: “addhops 2+i (ttl i)“, where first you get the variation from the default value (2). Then you get the current and new ttl-value. Hint: The command only works, if you are online. If you are not you will get the error message: cannot perform command; section name still unknown Example: set ttl-value to 5

C:\Programs\cFosSpeed>spd sethops 5
add_hops = 3 (ttl 5)

spd speed

With the spd command “speed”, you get an overview of various traffic shaping values. The most important are:

• maxrx – maximum download bandwidth in cps
• method – Information about the transmission method used: PPPoE, PPPoA, PPPtP, Cable, etc.
• addhops – here the current ttl value is displayed in brackets.
• pingcnt – total number of pings sent
• pongcnt – total number of ping responses (pongs) received
• txspeed – Upload bandwidth in cps

Example:

C:\Programme\cFosSpeed>spd speed
Current shaper settings (v13.00.3000):
maxtxraw=1445K maxtxacked=1433K maxrx=6030K avg_time=4000
mindelay=7441 variance=3896 vari_fixed=0
reg_id=3 method=adaptive (8) pinger=udp_km3
voltxraw=10.86G voltxacked=9704M volrx=18.36G time_used=10d 7h
maxiplen=1492 rx_limit=inf tx_limit=inf inhibit_bridged=0
ping_cnt=115966 pong_cnt=105300 (90.8%) burst_cnt=3
adapter=WIFI link speed: rx=108.3M tx=43.87M
txspeed=1517K fixed=0 tx_bounce_cnt=5 calibrated=100
tx delay=10000-14896 rx delay=20000-25393 delay_auto=1

spd tsclear

The command “spd tsclear” clears the traffic shaping settings for the current connections. The current data in the corresponding section of the data.ini file is deleted. The connection can now be recalibrated.

Example:

C:\Programme\cFosSpeed>spd tsclear
traffic shaping settings cleared.

spd dump

With the “dump” command you can write a text file (dump.txt) that records all datapackets. Example:

C:\Programme\cFosSpeed>spd dump ip
dump ip (64)
dump data: IP packets.

C:\Programme\cFosSpeed>spd dump off
dump off (0)

functions:

    on  : turn on writing of dump file
    off : turn off writing of dump file
    in  : dump only incoming data packets
    out : dump only outgoing data packets
    net :
    app :
    ign :
    ip  : dump IP packets (possibly fragmented)
    ipr : dump IP datagrams (after IP reassembly).

spd cstat

The “cstat” command provides upload statistics for sent data packets of the individual cFosSpeed ​​traffic shaping classes (highest, higher, high, default, low and lowest). The first line of the command output indicates whether traffic shaping is enabled. The upload bandwidth in cps (txspeed) and the maximum queue overflow value are also specified here.

Example:

C:\Programme\cFosSpeed>spd cstat
shaping is currently enabled; txspeed = 19659, max_queue_size = 58,977

class highest -prio 100
  sent            2,431 (  4%) packets         68,068 (  0%) bytes
  in queue            0        packets              0        bytes

class higher -prio 90
  sent           16,777 ( 34%) packets        671,716 (  3%) bytes
  in queue            0        packets              0        bytes

class high -prio 80
  sent           10,489 ( 21%) packets      1,235,682 (  5%) bytes
  in queue            0        packets              0        bytes

class default
  sent           14,593 ( 29%) packets     19,897,796 ( 90%) bytes
  in queue            0        packets              0        bytes

class low -prio 0 -speed 25%,-10
  sent            4,820 (  9%) packets        221,720 (  1%) bytes
  in queue            0        packets              0        bytes

class lowest -prio 0 -speed 25%,-30
  sent                0 (  0%) packets              0 (  0%) bytes
  in queue            0        packets              0        bytes

class drop
  dropped             0        packets              0        bytes

queue overflow        0        packets              0        bytes

spd ver

The “spd ver” command outputs information about the currently installed version. The version number, build number and installation date including the installation time are displayed. You will also receive information about the operating system and processor used. Finally, the current installation date is stated as well as the installation and info directories of cFosSpeed.

spd gset

With the copmmand spd “gset” some of the cFosSpeed variables are listed. They switched on (1), off (0) or set to certain value. To switch a function on and off or set it to a certain value you can use commands with the folowing structure “spd gset <function>=X” (where X is 1, 0 or the value to be set) If you add “-save” you can save the settings and they will be also set after the next reboot of your system. Enter “spd gset” and you will get:

examples

Turn on the firewall:

d:\tools>spd gset firewall=1
firewall = 1

Turn off permanently Traffic Shaping:

C:\Programs\cFosSpeed>spd gset shape=0 -save
shape = 0
value saved.

Turn on/off packet passthru:

C:\Programs\cFosSpeed>spd gset passthru=1
passthru = 1

C:\Programs\cFosSpeed>spd gset passthru=0
passthru = 0

Possible values:

     0 : off
     1 : ignore all packets, pass them on to the next driver immediately.
     2 : ignore all packets, send them through the cFosSpeed connection
         engine, but don't do anything with them.

Disable writing of firewall log file fwlog.txt:

C:\Programme\cFosSpeed>spd gset fwlog 0 -save
fwlog = 0
value saved.

prevent cFos / cFosSpeed from saving data.ini, budget and traffic stats every 10 minutes: “spd gset save_in_session 0 -save“

C:\Programme\cFosSpeed>spd gset save_in_session 0 -save
save_in_session = 0
value saved.

Specify after how many seconds of inactivity the LAN port (and status window) will be closed automatically: “spd gset port_close_time ‘n’ ”

C:\Programme\cFosSpeed>spd gset port_close_time 5
port_close_time = 5

spd reset_budget

With the command spd “reset_budget [n]” you can reset online budget with the number ‘n’ (n=0..9). If ‘n’ is omitted the current budget is reset.
