Hi,



I see libnss3-0d

          libnss3-1d

          libnss3-1d-dbg

          libnss3-dev

etc.


I have the following in my /usr/lib





-rw-r--r-- 1 root root 1156684 2008-05-29 02:52 libnss3.so.1d



-rw-r--r-- 1 root root   18876 2008-01-18 03:44 libnss_db-2.2.3.so







-rw-r--r-- 1 root root    8452 2007-05-18 05:57 libnss_extrausers.so.2





-rw-r--r-- 1 root root   33652 2008-02-01 21:08 libnss_ldap.so.2











What are libnss3.so.[0d,1d] etc?

Can anybody tell me something about the various nss packages that are there in ubuntu (hardy). lrwxrwxrwx 1 root root 13 2008-07-17 16:47 libnss3.so -> libnss3.so.1d lrwxrwxrwx 1 root root 13 2008-07-17 16:47 libnss3.so.0d -> libnss3.so.1d lrwxrwxrwx 1 root root 23 2008-07-07 16:00 libnss_compat.so -> /lib/libnss_compat.so.2 lrwxrwxrwx 1 root root 14 2008-07-17 16:47 libnss_db.so -> libnss_db.so.2 lrwxrwxrwx 1 root root 18 2008-07-17 16:47 libnss_db.so.2 -> libnss_db-2.2.3.so lrwxrwxrwx 1 root root 20 2008-07-07 16:00 libnss_dns.so -> /lib/libnss_dns.so.2 lrwxrwxrwx 1 root root 22 2008-07-07 16:00 libnss_files.so -> /lib/libnss_files.so.2 lrwxrwxrwx 1 root root 23 2008-07-07 16:00 libnss_hesiod.so -> /lib/libnss_hesiod.so.2 lrwxrwxrwx 1 root root 24 2008-07-07 16:00 libnss_nisplus.so -> /lib/libnss_nisplus.so.2 lrwxrwxrwx 1 root root 20 2008-07-07 16:00 libnss_nis.so -> /lib/libnss_nis.so.2 lrwxrwxrwx 1 root root 17 2008-07-17 16:47 libnssutil3.so -> libnssutil3.so.1d lrwxrwxrwx 1 root root 17 2008-07-17 16:47 libnssutil3.so.0d -> libnssutil3.so.1d Whereas my other Linux box which has Suse 10 on it has only libnss3.so, libnspr4.so and all.

strings libnss3.so | grep -w NSS

Kai

I don't understand why Ubuntu uses versioning of the .so files, it should not be necessary. The newest NSS libs should work fine with software that expects the older versions, because of NSS' promise that it should always be possible to replace old binaries with newer NSS binaries. Try to grep the .so files for string NSS, it should reveal the version number strings.
