service ftp di solaris 10 ga mau running karena nsswitch.conf 28 March 2011

2 hari ini dibuat pusing sama service ftp di nas yang running di solaris 10. mulai deh rasa penasarannya tinggidan terpaksa loading memory tentang svcs, svcadm, inetadm di kepala.

command pertama yg disubmit adalah svcs -xv untuk memastikan bahwa service ftp memang problem

[root@nas /]# svcs -xv
svc:/network/ftp:default (FTP server)
State: maintenance since March 22, 2011 10:57:19 AM CIT
Reason: Restarter svc:/network/inetd:default gave no explanation.
See: http://sun.com/msg/SMF-8000-9C
See: man -M /usr/share/man -s 1M in.ftpd
See: man -M /usr/share/man -s 1M ftpd
Impact: This service is not running.

[root@nas /]# inetadm -l network/ftp:

dari hasil command2 diatas bener2 blank nih … dari hasil tanya2 ke temen, disarankan liat services yang running via inetd. aku coba finger.

[root@nas /]# inetadm | grep finger
enabled   maintenance    svc:/network/finger:default

ternyata mati juga, berarti problemnya di inetd. ada beberapa kemungkinan sih, yg pertama aku liat /etc/nsswitch.conf

ada yang menarik dari isi file ini

networks:   ldap [NOTFOUND=return] files
protocols:  ldap [NOTFOUND=return] files
rpc:        ldap [NOTFOUND=return] files
ethers:     ldap [NOTFOUND=return] files
netmasks:   ldap [NOTFOUND=return] files
bootparams: ldap [NOTFOUND=return] files
publickey:  ldap [NOTFOUND=return] files

kok hasil NOTFOUND return ya ? berarti kalo ldapnya bermasalah maka search entry ga akan dilanjutkan ke files padahal entry di ldap server ga ada informasi tentang network & hosts

setelah return aku ubah menjadi continue, problemnya solved.

reference nsswitch.conf aku ambil dari http://www.softpanorama.org/Solaris/Reference/etc/nsswitch.shtml
