Multiple domains

[Michela Ronchi_2]

Hi all,

does anybody know if I can set a second domain name as an alias in /etc/hosts file without messing up the SAP R/3 instance running on my server?

Ex:
XXX.XXX.XXX.XXX pippo.pluto.com pippo.paperino.com pippo

Thanks and cheers,
Michela

You can, but no use of it, apps/programs do nslookup on ip address. First entry will precedence in all cases.

If on host name, then yes you can do that.

What exactly you are trying to do??

Hi,
the customer "mail relay" seems to have problems accepting cennections from a different domain and they don't want to change it, so I have to find a way to send to the mail relay a "false" domain name.
If you know a different way... Thanks
Cheers,

Then maybe the domain masquerading feature in sendmail.cf is the right place to look!

Search this forum for sendmail masquerading!

Basically you need to change the DM entry in /etc/mail/sendmail.cf

Yes. You can.

xx.xx.xx.xx pippo.pluto.com pippo.paperino.com pippo

It will work when you set hosts: entry in /etc/nsswitch.conf as,

hosts: files

hth.

Hi all,
I already configured the sendmail.cf file with the domain I wanted. And I added the second domain in /etc/hosts.
SAP is still working fine, but the customer mail relay seems to have problems.
I will go on trying to find out what's wrong with it.
Thanks to everybody.
