Using sendmail as a client with AUTH

VAS · 04-24-2006, 04:08 PM

My ISP provides a mail service, but mail server requires authentification for sending mail, and I need to configure mail server to send mail because I want to use mutt as mail reader. I found an article how to do that, but "makemap" says:

Code:

smmurf:/etc/mail/auth# makemap hash client-info < client-info
makemap: error opening type hash map client-info: Permission denied
smmurf:/etc/mail/auth#

Does anyone know how to fix it, or may be someone can give an advice what mail server wouldn't cause such problems with authentification, and give a link to manual how to configure it.
Thanks.

It could be that you don't have permission to open the client-info file that contains the list of client info. It could also be that you don't have permission to create the client-info.db in the directory where you ran the command. Or, it may be that the info in the client-info file wasn't in a format suitable for a hash map.

Have you had a look at the SMTP AUTH HOWTO here at http://www.linuxquestions.org/questi...d.php?t=224543? I've used it to build a couple of systems and it works well.

Well, I don't think the problem is in permissions, because as you see in my bash prompt I tried to do it as root. So may be the problem is in file format, it contains such a string:
AuthInfo:mail.myISP.net "U:my_login_name" "I:my_email_address" "P:my_password"

I've just tried to use file format that you give in your HOWTO, but the error still exists. So I have no idea how can it be fixed :?

From the manpage:

Quote:

makemap [-C file] [-N] [-c cachesize] [-d] [-D commentchar] [-e] [-f] [-l] [-o] [-r] [-s] [-t delim] [-u] [-v] maptype mapnam
DESCRIPTION
Makemap creates the database maps used by the keyed map lookups in sendmail(8). It reads input from the standard input and outputs them to the indicated mapname.

You are taking the input from the exact same file that you are using as an output.
Do you maybe want:
smmurf:/etc/mail/auth# makemap hash client-info.db < client-info

My authinfo file has the following format:

Code:

AuthInfo:mail.isp.domain "U:username@isp.domain" "P:apassword" "M:PLAIN"
AuthInfo: "U:username@isp.domain" "P:apassword" "M:PLAIN"

I've payed attention on the filenames yet, and tried to give different names, but nothing changed

Code:

smmurf:/etc/mail/auth# makemap hash client-info.db < client-info
makemap: error opening type hash map client-info.db: Permission denied

The problem isn't in the file format - I've just checked it twice again.

It sounds like you don't have write permissions for the directory (regardless of being root). What is the output of ls -ld /etc/mail/auth please? I get the following on my system:

Code:

/tmp/auth# /usr/sbin/makemap -v hash authinfo < authinfo
makemap: error opening type hash map authinfo: Permission denied

VAS · 04-24-2006, 06:07 PM

smmurf:/etc/mail# ls -ld auth/
drw------- 2 root smmsp 80 2006-04-25 02:00 auth/

Yes, it was a problem, thanks.
I'm sorry for such a simple question and that I wasn't attentive

It's permissions then - here's mine before and after altering permissions:

Code:

/tmp/auth# ls -ld /tmp/auth
drw------- 2 root root 4096 2006-04-25 09:01 /tmp/auth
root@fender:/tmp/auth# /usr/sbin/makemap -v hash authinfo < authinfo
makemap: error opening type hash map authinfo: Permission denied
root@fender:/tmp/auth# chmod -c 0700 /tmp/auth
mode of `/tmp/auth' changed to 0700 (rwx------)
root@fender:/tmp/auth# /usr/sbin/makemap -v hash authinfo < authinfo
key=`authinfo:mail.isp.domain', val=`"U:username@isp.domain" "P:apassword" "M:PLAIN"'
key=`authinfo:', val=`"U:username@isp.domain" "P:apassword" "M:PLAIN"'

No problem - glad it's working
