Davon gibt's nur 2 im chroot (libresolv.so.2, libc.so.6), die restlichen
15 nicht.
Vergleiche ich das mit dem chroot auf einer anderen Kiste, auch Debian
Wheezy/amd64, finde ich keinen Unterschied:
find /var/spool/postfix/lib/x86_64-linux-gnu/ -type f | sort | xargs md5sum
>/tmp/x2
>Für die Rejections ist doch der smtpd zuständig, oder?
Das sagen zumindest das Log und auch strace.
Aber ich bin der Sache nun naeher:
ein `ln -s x86_64-linux-gnu x86_64` in /var/spool/postfix/lib, und das
Reverse-Lookup geht wieder. Stutzig gemacht hat mich:
13099 open("/lib64/tls/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such
file or directory)
13099 open("/lib64/tls/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
13099 open("/lib64/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file
or directory)
13099 open("/lib64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
13099 open("/usr/lib64/tls/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No
such file or directory)
13099 open("/usr/lib64/tls/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such
file or directory)
13099 open("/usr/lib64/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such
file or directory)
13099 open("/usr/lib64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
13099 open("/lib/tls/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such
file or directory)
13099 open("/lib/tls/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
13099 open("/lib/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file
or directory)
13099 open("/lib/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
13099 open("/usr/lib/tls/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No
such file or directory)
13099 open("/usr/lib/tls/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file
or directory)
13099 open("/usr/lib/x86_64/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such
file or directory)
13099 open("/usr/lib/libnss_dns.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
Wobei ich noch dahinterkommen muss, warum der nicht in x86_64-linux-gnu
sucht im chroot... (warum's so hinkopiert wird, ist nach kurzem Blick
ins chroot-Setup klar).
cheers,
