Preparing Test fcast (mcast w acl)

Compile fcast

Sending/receiving

Configure Mcast on all client (refer to other howtos).

On receivers: 

 ./fcast -v6 -recv -int -a224.0.0.251

On Sender: 

 ./fcast -send -v6 -a224.0.0.251 -p1024 bigfile

Test 1

procedure

  • Create checksum of a 10M random file and transfer the md5 to receiver.
    1. dd if=/dev/urandom of=10Mbigfile bs=1024 c=10
    2. md5sum 10Mbigfile > 10Mbigfile.md5
    3. Sender starts to send 10M file.
    4. Receiver starts after that

    Observation

  • checksum fails.
    • orig file 10240 Kb while received file 10180 Kb

Test 2

procedure

  • Create checksum of a 1108Kb text file (enUS.dic). - cat -n /usr/share/myspell/enUS.dic > nenUS.dic
  • Sender starts to send the file.
  • Receiver starts after that

Observation

  1. receiver get the file correctly.

Conclusion 1

  • some problem with binary files. Maybe the serialization in code.

Testing tzi flute (mcast w acl)

Compile binaries

Binaries are in 

  /mnt/data/src/20_mcast_ws/tzi_flute/papageno-trunk/examples/flute

Attention They are configured in Automake with noinst_ prefix.

Sending/receiving

Configure Mcast on all client (refer to other howtos).

On receivers: 

 ./flutesender -a 224.0.0.251 -c 5 -e 'rs' n_en_US.dic

On Sender: 

 ./fluterecv -a 224.0.0.251 -c 5 -C 'rlc'

Test 1

procedure

Sender sends directly to receiver's ip: 

 ./flutesender -a 192.168.101.121 -c 1 files/n_en_US.dic
