Well, I ran ldd /usr/sbin/sshd, ldd /usr/sbin/*, ldd /usr/bin/*,
ldd /sbin/*, ldd /bin/*; looked through it, grepped for 'intl'
without any instances found. Then I added two echo lines to the
rc.network script:
echo "Starting ppp as \"${ppp_user}\""
echo "JUST BEFORE - ${ppp_command}"
su -m ${ppp_user} -c "exec ${ppp_command}"
echo "JUST AFTER"
And here's what I've got after reboot:
# dmesg -a
<...>
Starting ppp as "root"
JUST BEFORE - /usr/sbin/ppp -quiet -ddial default
/usr/libexec/ld-elf.so.1:
Shared object "libintl.so.6" not found
JUST AFTER
<...>
# ldd /usr/bin/su
/usr/bin/su:
libutil.so.3 => /usr/lib/libutil.so.3 (0x28069000)
libskey.so.2 => /usr/lib/libskey.so.2 (0x28072000)
libmd.so.2 => /usr/lib/libmd.so.2 (0x28079000)
libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x28082000)
libkrb.so.3 => /usr/lib/libkrb.so.3 (0x2809b000)
libcrypto.so.3 => /usr/lib/libcrypto.so.3 (0x280b4000)
libcom_err.so.2 => /usr/lib/libcom_err.so.2 (0x281ab000)
libc.so.4 => /usr/lib/libc.so.4 (0x281ad000)
Here I almost pressed the "Send" button in my Thunderbird, but
oops. Back to the shell :-)
# man su
<...>A shell is then executed.<...>
Yep, my default shell for root is bash.
# ldd bash
bash:
libncurses.so.5 => /usr/lib/libncurses.so.5 (0x280e0000)
libintl.so.6 => /usr/local/lib/libintl.so.6 (0x28121000)
libc.so.4 => /usr/lib/libc.so.4 (0x2812a000)
libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x281c3000)
So apparently I have probably changed the default shell from csh
to bash on both machines right after that portupgrade. I changed
back to sh now - and the error is gone.
The only question I have now is how come I've never read about this?
I've read the Handbook and the Complete Freebsd and literally
thousands of other pages concerning FreeBSD management. I have
never seen a warning about changing the default shell for root.
Or am I just too blind?..
Anyways, thank you Kris and Toomas for your kindest response!
Thanx!
Best wishes,
Andrew P.
