When copy file by rcp command, if the file > 2GB, it will not work. On host(Ubuntu 12.04.4 LTS): root@wl:/build#du -sh file2_2G_h.img 2.1G file2_2G_h.img root@wl:/build#$rcp file2_2G_h.img root@target_ip:/media/sda4/test rcp: lost connection
On target(inetutils has installed): root@17287:/media/sda4/test1# rcp root@host_ip:/build/file2_2G_h.img . rcp: rcp[970]: segfault at 22 ip 000000391dc47ec7 sp 00007ffd858e2d50 error 4 in libc-2.18.so[391dc00000+1a3000] Segmentation fault The cause is that it used incorrect data type on file size in sink() of rcp.
