Aug 19, 2009

Quote:
Summary:
SELinux is preventing sendmail (system_mail_t) "read" to eventpoll (httpd_t).
Detailed Description:
SELinux denied access requested by sendmail. It is not expected that this access is required by sendmail and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access.
Allowing Access:
Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for eventpoll,
restorecon -v 'eventpoll'
If this does not work, there is currently no automatic way to allow this access.Instead, you can generate a local policy module to allow this access - see FAQ(url) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended.Please file a bug report (url) against this package.
i m using centos 5.4 for Data Server, there i hv shared a directory to store data. i want, when ever owner of that data does delete any thing from directory, system should send me a mail with logs of that deletion action with the detail some thing like bellow

These logs should be sent me by email automatically.
i had configured mail server in linux. i had configured sendmail in linux client . i have error while sending mail through thunderbird smtp auth error how can i resolv the issue .....
I try to install IPsec-Tools on Slackware 13, but I get an configure error: configure: error: Security Context requested, bu no selinux support! Aborting. I'm linux newbie and I'm following a slackware-basics tutorial, I did as in the tutorial, but the configure stops and aborts:
[Code]... What can I do? How can I enable/install selinux support? I guess it's related with AH and ESP protocols, which in my kernel are defined as modules (m). If so, how can I enable them?
in Lucid ive been trying to get the mail applet to light up green by sending myself mail. Does this applet only light up when IMs r received or does this also work with evolution and if so what might i have done wrong in evolution, ive tried it with evolution open and evolution closed.
I have two servers relavant here: mail.domain.com (1.1.1.1) - which is the nameserver and the mail server for domain.com. www.domain.com (2.2.2.2) - which is the www subdomain for domain.com domain.com (cname www.domain.com) - an alias for www.
The zone file for domain.com lists mail.domain.com as the MX server for domain.com. 2.2.2.2 is actually being served web pages as a virtual host. It's real hostname is www.anotherdomain.com. Mail for domain.com works pretty well, in general. However, if I attempt to send mail from www.domain.com (or its alias domain.com), I get "mail for domain.com loops back to myself" in the postfix logs. On 2.2.2.2 /etc/postfix/mail.cf has mydestination = www.anotherdomain.com, localhost. How do I tell postfix on 2.2.2.2 that mail for domain.com needs to be delivered to mail.domain.com?
this is the allert i got:Code:Summary:Your system may be seriously compromised! /usr/sbin/NetworkManager tried to loada kernel module.Detailed Description:SELinux has prevented NetworkManager from loading a kernel module. All confinedprograms that need to load kernel modules should have already had policy writtenfor them. If a compromised application tries to modify the kernel this AVC willbe generated. This is a serious issue.Your system may very well be compromised.Allowing Access:Contact your security administrator and report this issue.Additional Information:
I am learning SELinux from LinuxCBT and I'm stuck at one place. Now video is on RHEL 4 (so tell me if things has changed since, cause I can't find anything related) shows how to disable SELinux security on httpd.first I don't know diff between initrc_t and uncofined_t; and second I don't know if something is wrong is everything is all right.
I have installed Fedora Core 11 with SELinux enforcing.It appears (via log files) that if I use a .forward file in the home directory for root that SELinux prevents the use of this mechanism for forwarding e-mail.Is there a way to continue to use SELinux and be able to forward root's e-mail to an outside account?
l to a group in Linux? for example, I want to send a notification mail to 20 people and I want to create a group of these 20 people and want to send them the notification
I want to send mail to potential customers from my localhost server in my SOHO. I have a web site hosted with a company called geek hosting [URL], so I have access to the mail services through them... I want to their mail server to push things out to the world form my localhost server.
I do have a registered domain name which the hosted site runs under
the domain name for my centos 5.4 server is localhosthost.localdomain.
I am very new to CentOS and running a server in general. I managed to get a server setup with CentOS, and it's running a wordpress driven social networking site. Everything is fine except sometimes my server won't send registration/activation emails to some email addresses. This is a huge problem because people signup but then can't activate their account. I don't understand why its sending some and not sending others based on the email domain? The guys at wordpress said "it's that your server does not support SMTP or at least wp_mail() in its normal form" but that doesn't mean much to me.
How is it possible to send email using the "mail" program? I tried: echo "testing" | mail -s "test" myaddress@gmail.com But nothing happened. I made sure that the sendmail daemon was running before I tried. Is there anything else that I have to set up first?
I have OpenSuse 64bit running a web site. I have a form on this site here:- Dynamic Systems Group The script itself works and I have tested it on another hosted server and it works fine. However on my server the email the script sends never arrives, which must be a problem with my Postfix settings I guess. However I also have two pages on my site for testing sending of mail, which BOTH report a postive result:-
[URL]
However even though these pages report successful send the mail stil never arrives. I have looked at many pages and forums on the internet and I am really, really confused as to how to set up Postfix. On the Suse box I have the Mail Server configured in Yast to send mail via my Gmail.com account using TLS and authentication but still no success!
I have kubuntu 9.10 and I would like to configure Ubuntu to can send mail from command line with mailx. I've saw that I need to install a MTA. But I don't know wich install and how.
I follow this tutorial:

But when I try to send a message, in the mail.log says me:
Code: Jan 5 10:21:33 david postfix/smtp[3795]: 41AEA41DBE: to=<pepelu@gmail.com>, relay=alt1.gmail-smtp-in.l.google.com[209.85.223.73]:25, delay=1086, d elays=1022/0.01/32/32, dsn=4.7.0, status=deferred (host alt1.gmail-
When I sending mail to defined mail on the internet page I have to configure Evolution and open it for sending. Is it possible to send mail without opening Evolution. Just send to defined mail on internet page.
I want to send mails via gmail with php. I need to know how to configure main.cf, php.ini, postfix,smtp... and all what is necessary. I tried a lot but no results.
I'm using the mail command and I am able to send mail to my gmail account with out any problems. However when I send mail to deco -at- mycompany.com I nothing happens and no mail ever arrives in my mailbox. It might be worth mentioned that my centos5 is a virtual machine on the same server as the company exchange mail server.
I ran mail (aka mailx) and opened an account foo. If I remain inside the program, the command 'account foo' prints the account data. Good. But if I exit the program, and rerun it, then the command 'account' has no output which is to say I have no account.
I tried the command echo "Test" | mailx -s "Test subject" reciever@test.com -- -f Tester@gmail.com
But in the mailbox of reciever, i can find the sender name as Tester@gmail.com. My requirement is to show the sender as 'Tester' alone, without the domain name.
I'm trying to get logwatch to email me. I think my logwatch.conf file is okay. I have postfix installed. The mailer as far as I can tell is set correctly ("usr/bin/mail"). When I run logwatch - I get "no mail for aubrey"
Heres my logwatch.conf file: Code: linux-qwkb:/home/aubrey # edit /usr/share/logwatch/default.conf/logwatch.conf ######################################################## # This was written and is maintained by: # Kirk Bauer <kirk@kaybee.org> # # Please send all comments, suggestions, bug reports, # etc, to kirk@kaybee.org. # ######################################################## .....
Postfix is not sending mail, I did a basic test of sending an email locally using the Linux mail command, and nothing was delivered, and I couldn't find an error either.
Where is the log for postfix located?
In main.cf I changed: myhostname mydomain mynetworks home_mailbox (I want to use Maildir/)
