Question local users can't see website or get mail


I have users that can't pickup their mail from the local subnet, but can pick it up using a web based interface such as mail2web.com

Also, these same users can't see our website from the local subnet but can see it from outside the subnet.

Any thoughts? Mandrake 9.1 Postfix 2.0.6 Apache 2.0

Is it only affecting some users or all users? If you login from their PCs can you get in?

Hi:

It only seems to be affecting some users on the website, and more on email.

But it seems to be linked to user accounts and not PC configuration? ie - the same people have the same problems regardless of what PC they use?

What are you using for mail storage? pop3? Imap? What version of these are you using and do they authenticate against a database/directory/passwd file?

It is regardless of what PC they are using, unless they go through ssh or some type of webmail.

Yes they authenticate through the /etc/passwd file

And recently, I did have to reload the os, but it seemed to be working ok at first.

postfix 2.0.6, mandrake 9.1



I think that was all the questions, I'll check to make sure I hit everything.

Postfix is really only handling SMTP.

I assume you are meaning that the problem comes when they connect with a client like Mozilla or Outlook? You will most likely be using pop or IMAP to handle that.

If you can find out what you are using there may be some meaningful entries in it's log files.

If you have reloaded the OS recently - did you make sure that the permissions on the storage directories were correct for these users?

Yes, it's pop3 and it is all services directly even ssh. But when they go out to the web and come in they can get in.

Shorewall is also running on the machine

what file permissions should I check, the home directories??


Thanks,

Michele

No services to SOME local clients

I'm one of the users that is having the problem Michele is describing. If I'm NOT on the local subnet, I can log in and get my mail fine, view the website, ssh, etc. However, when I'm on the local subnet, none of these services are available to me and about five or six other people.

That seems to be the kicker. I could understand if it was all local users, it would probably be a misconfiguration of Shorewall on that machine. Disabling Shorewall temporarily on a reboot caused us all kinds of other problems; we really don't want to attempt to do that again to test.

I can't really see it as being a permissions problem, as it is also affecting anonymous services such as httpd.

Any suggestions on where/what to look for would be appreciated.

Thanks,

Jeremy

This really does seem odd. I'm still not sure which pop3 server you are using - there may be a way to set restrictions in it's configuration - if you can find out the name and version I can help check the docs for it.

From what you have said (correct me if I'm wrong):
1) We can discount internal IP addresses being blocked - for instance User1 can access e-mail from internal PC1 and internal PC2 but User2 cannot access e-mail from either internal PC1 or internal PC2.
2) We can also discount user specific problems since User1 can access e-mail from everywhere and User2 can still access mail but not on the LAN.
