Apache gets sendmail permission denied in selinux

From http://www.simplemachines.org/community/index.php?topic=446074.0

Hi everyone,
  when installing SMF 2.0 on RHEL6 recently, I found that emails were not being sent, with the error
Code: [Select]
sendmail: fatal: chdir /var/spool/postfix: Permission denied
showing up in /var/log/httpd/error_log.  This was caused by the apache user not having SELinux permission to send email. This could also occur on other distributions which use SELinux (particularly Fedora and CentOS, but possibly others as well), if it is set to "Enforcing".

You can check this by using
Code: [Select]
/usr/sbin/getsebool httpd_can_sendmail
which will report
Code: [Select]
httpd_can_sendmail --> {on|off}
and if it is off, you can turn it on using
Code: [Select]
sudo setsebool -P httpd_can_sendmail 1
with the "-P" for persistent (across reboots).


Important note, it can look like it's doing nothing, but it actually is.

It will come back in about 1 minute

Fixing a https Cert in Windows

 I renewed a https cert today in Windows and had problems with the new Cert sticking in Windows It would add fine, without error, but would disappear when the IIS Server Certificates screen would refresh.  Open the Certificates in MMC (Local Machine) and inspecting the Web Hosting gave a clue, the new certificate was there, but with a key - the private key was missing.  Could be because the original certificate was created on a completely different machine and imported to this new server.  At any rate, a simple certutil command fixed it .  A tip I received from  SSL disappears from the certificate list on Windows server - SSL Certificates - Namecheap.com Key steps are:  Double-click the certificate and go to  Details  tab. In certificate details locate the  Serial Number  field, click on it and copy its value. Open Command Prompt, pressing  Win+R  and typing  cmd , then click  OK In the command prompt type: ...

Ever need to reset a password in Bonobo Git Server ?

So, you've forgotten your password to bonobo git. Step 1: Get access to the sqlite file, probably called something like  Bonobo.Git.Server.db, sitting in the "wwwroot\Bonobo.Git.Server\App_Data" directory. Step 2: Using another tool, generate an md5 hash of your new desired password (as far as I know, sqlite does not have md5 capability) Step 3: Back in sqlite, using SQL, update the relevant user record, something like update User set Password = UPPER( 'thenewMD5hash') where Username = 'admin' ; Step 4: That's it, you are done, log in with your newly found password.
