| 安装 | #login, mkdir data #yum install cvs #cvs -z3 -d:pserver:anonymous@tsunami-udp.cvs.sourceforge.net:/cvsroot/tsunami-udp co -P tsunami-udp #cd tsunami-udp #cvs update #yum install libtool* #./recompile.sh #sudo make install # copy bin to user/local/bin
|
| Server端 执行
| #cd /data 创建一些指定大小文件 #dd if=/dev/zero of=50M.file bs=1M count=50 #dd if=/dev/zero of=1G.img bs=1M seek=1000 count=0 #ls -lht
#tsunamid * #开始listening
#tsunamid --port 46224 /mnt/bigephemeral/* 指定端口和目录
|
| client端 执行
| #cd /data #tsunami > connect 50.97.229.146 > get 50M.file > get 1G.img
或者直接执行
