[tpop3d-discuss] RE: xinetd, tpop3d & Redhat 7.1

[Jerry Liang]

Dear All:

I have tried to install tpop3d 1.3.5 on a i386 pc with Redhat 7.1.

Tpop3d works well with daemon mode. When I try to go to
tcp wrapper mode, there are some things strange.

I use the following configuration command:

./configure --enable-auth-passwd --enable-shadow-passwords --enable-tcp-wrappers

Then, I tried to compile the source code with the Makefile. I got the following 
message:

gcc  -Wall -g  -o tpop3d  auth_mysql.o auth_other.o auth_perl.o auth_pam.o auth_
passwd.o authswitch.o cfgdirectives.o config.o connection.o errprintf.o listener
.o locks.o mailbox.o maildir.o mailspool.o main.o md5c.o pidfile.o pop3.o signal
s.o stringmap.o strtok_r.o substvars.o tokenise.o util.o vector.o  -lwrap -lpam
-ldl -lcrypt
/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../libwrap.a(hosts_access.o): In f
unction `host_match':
hosts_access.o(.text+0x616): undefined reference to `yp_get_default_domain'
collect2: ld returned 1 exit status

libwrap.a can be found under /usr/lib. Thus, I edited the Makefile. Originally, 
the LIB 
variable is assigned as:

LIBS = -lwrap -lpam -ldl -lcrypt

I modified this line as:

LIBS = -lwrap -lpam -ldl -lcrypt -lnss_nis

Then, the Makefile can be run successfully. But this is not the end of the 
story.

Instead if inetd.d, Redhat 7.1 has adopted xinetd for tcp wrapper structure. 
Thus, I 
have to edit /etc/xinetd.d/ipop3 as the following:

service pop3
{
        socket_type             = stream
        wait                    = no
        user                    = root
        server                  = /usr/local/sbin/tpop3d
        log_on_success          += USERID
        log_on_failure          += USERID
#       disable                 = yes
}

And I have the following tpop3d.conf:

listen-address: 10.0.0.7
max-children:   4
mailbox:        /var/spool/mail/$(user[0])/$(user[1])/$(user)
auth-passwd-enable:     true
auth-passwd-mail-group: mail
tcp-wrappers-name:      pop3


When I used my mail reader trying to get mail from 10.0.0.7:110, I got the 
following 
log in /var/log/maillog:

Apr  3 13:58:59 pc7 tpop3d[6787]: TCP Wrappers support enabled, using daemon nam
e `pop3'
Apr  3 13:58:59 pc7 tpop3d[6787]: listener_new: bind(10.0.0.7:110): Address alre
ady in use
Apr  3 13:58:59 pc7 tpop3d[6787]: /etc/tpop3d.conf: no listen addresses obtained
; exiting


And I'm not able to get mails hereafter.

Please give me your advices.

Best Regards,

Jerry
