IIRC, OpenWRT runs everything (or most everything) from the shell as root, so su is not needed. Is there something you are doing that needs su to work?

[OpenWrt-Users] su utility in OpenWRT "White Russian" release
Hi, I have an OpenWRT router with "White Russian" release in remote location. It has no "su" command and if I inspect the package/busybox/config/loginutils/Config.in file in http://downloads.openwrt.org/whiterussian/0.9/whiterussian-0.9.tar.bz2, then looks like BusyBox was compiled without "su" command. In addition, there seems to be no "coreutils-su" package for "White Russian" as there is for example for "Backfire"( OpenWRT 10.03). I installed OpenWRT "Backfire" to identical router and installed the coreutils-su_7.2-1_brcm47xx.ipk package and then copied /usr/bin/su to this remote "White Russian" router. While the binary architecture should be correct, it does not run: root@wr:~# /usr/bin/su /usr/bin/su: symbol 'stdout': can't handle reloc type 0x7e root@wr:~# Error above should indicate to library issues. According to ldd "su" binary requires following libraries: libcrypt.so.0 => /lib/libcrypt.so.0 (0x2aabe000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x2aae2000) libc.so.0 => /lib/libc.so.0 (0x2ab02000) ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x2aaa8000) In "Backfire", where "su" binary was copied from, they have following versions: libcrypt-0.9.30.1.so libgcc_s.so.1 libuClibc-0.9.30.1.so ld-uClibc-0.9.30.1.so In "White Russian" they have following versions: libcrypt-0.9.27.so libgcc_s.so.1 libuClibc-0.9.27.so ld-uClibc-0.9.27.so I guess it is not safe to simply copy newer libraries into the "White Russian" router as it might break some programs. Should I install OpenWRT "White Russian" to this spare router and try to copile coreutils or coreutils-su there and then again copy the su binary into this remote router? If yes, then which coreutils or coreutils-su source version should I use in order to compile the su binary? I looked into https://github.com/openwrt/packages/tree/master/utils, but didn't find anything suitable. Or maybe there is some smarter way? thanks, Martin ___ openwrt-users mailing list openwrt-users@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-users
