Because lash is the only shell what works for me (telnet shell) and hush is now almost as small as lash im trying to get hush working for telnet shell
but like all other versions its not working (for me) Its a bit hard to debug because if i use hush i cant telnet anymore so i did make a firmware on my environment with the old lash as shell and from that shell i did run strace on the 1.6.0 hush i did made all possible compilations (with/without the options) but i always get a blinking cursur and that is strace gives me: execve("./hush", ["./hush"], [/* 4 vars */]) = 0 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TCGETS, {B38400 opost isig icanon echo ...}) = 0 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, 0, 0) = 0x1ce3000 old_mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, 0, 0) = 0x1cd7000 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, 0, 0) = 0x1ce6000 getcwd("/hdd/shell", 4097) = 11 read(0, <unfinished ...> i can do a {controll C} to get back to prompt (that will give me the last line of strace) if i enable the "ineractive mode" it looks almost ok but please read on strace gives me /hdd/shell # /hdd/stage2/adv/strace -F ./hush execve("./hush", ["./hush"], [/* 4 vars */]) = 0 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TCGETS, {B38400 opost isig icanon echo ...}) = 0 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, 0, 0) = 0x1cac000 old_mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, 0, 0) = 0x1cad000 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_ANONYMOUS, 0, 0) = 0x1caf000 getcwd("/hdd/shell", 4097) = 11 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(0, TIOCGPGRP, [143]) = 0 fcntl64(0, F_DUPFD, 255) = 255 getpgrp() = 143 fcntl64(255, F_SETFD, FD_CLOEXEC) = 0 ioctl(255, TIOCGPGRP, [143]) = 0 rt_sigaction(SIGTSTP, {SIG_IGN}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGTTIN, {SIG_IGN}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGTTOU, {SIG_IGN}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGINT, {SIG_IGN}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGQUIT, {SIG_IGN}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGTERM, {SIG_IGN}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGILL, {0x176f8f0, [ILL], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGTRAP, {0x176f8f0, [TRAP], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGABRT, {0x176f8f0, [ABRT], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGFPE, {0x176f8f0, [FPE], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGBUS, {0x176f8f0, [BUS], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGSEGV, {0x176f8f0, [SEGV], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGHUP, {0x176f8f0, [HUP], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGPIPE, {0x176f8f0, [PIPE], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGALRM, {0x176f8f0, [ALRM], SA_RESTART|0x4000000}, {SIG_DFL}, 8) = 0 setpgid(0, 0) = 0 getpid() = 144 ioctl(255, TIOCSPGRP, [144]) = 0 write(1, "\n\n", 2 ) = 2 write(1, "BusyBox v1.6.0 (2007-06-02 21:04"..., 72BusyBox v1.6.0 (2007-06-02 21:04:45 CEST) hush - the humble shell v0.02 ) = 72 write(1, "Enter \'help\' for a list of built"..., 46Enter 'help' for a list of built-in commands. ) = 46 write(1, "\n", 1 ) = 1 geteuid() = 0 write(1, "/hdd/shell # ", 13/hdd/shell # ) = 13 read(0, 0x1775d30, 4096) = ?
