I'm trying to configure Check_MK 1.2.8p20 (multisite-enabled) to work with BI notifications. I've set up the service account, have my aggregations working, but, upon check, I receive:

ERROR: Invalid json response (invalid syntax (<string>, line 1)): <!DOCTYPE HTML>

The long output produced by the agg check is the HTML for the login page as follows:

EDIT - ADDITIONAL NOTES Changed to form-based authentication, and login is still "successful", but now receiving:

ERROR: Aggregation "aggname" does not exist or user is not permitted

I've found very little documentation on the BI notifications, and am curious if someone has gotten this working properly.

Thank you

I've successfully set up check_mk 1.28 via OMD, which I know supports wildcards and regex for assignment of hosts/services to groups. I've tested the wildcards in the search box successfully, but the groups are not being populated and are showing up as "ineffective".

enter image description here enter image description here

All searches I've seen so far say that this should be possible, but I can't determine what is missing. Ideas?

DNS in my environment is a bit wonky at times. When Bareos connects to a client, the client is not always the one specified by the hostname. I have a cron script that runs jobs automatically and checks to see if the host and fd on the client match, but I'm wondering if there's a way to put a pre-run script that cancels a manually run job if the same info does not match.

Thank you

My environment consists of the following:

  • Users are on Office 2016 installed from Office365
  • Email is handled by Office365 Cloud installation

One user is experiencing an issue whereby they will receive some messages on their iPhone (using Outlook app), but the same messages will not appear on their desktop client.

  • I've checked for mail filters for the user, there are none.
  • I've checked the mail transport logs. No errors with messages being sent to the recipient
  • I've recreated the user profile on their laptop, pulling all mail fresh.

With all the steps above, the issue remains. Ideas are welcome for troubleshooting, as I'm baffled and can't reproduce with any other user.

Thank you

I've recently configured the laptops and workstations in my environment with BareOS. We are doing this as a preventative measure for data loss (part of a grander scheme of recommendations). With the large-ish number of them available, they're not always on the network (mostly laptops).

I'm wondering if there's a way in BareOS to check for a system being online and backing it up on a semi-random basis. Is this a custom scripting thing? If so, has anyone done anything like this?

TIA

I have 'frox' setup as the ftp proxy on one of my servers, but I need to have all traffic to this system to be forwarded to another ftp server. I know about transparent forwarding, but I can't seem to get it to work nor find great documentation. One of my requirements is that only a username WITHOUT the destination server be entered, e.g. ftpuser instead of [email protected]

Here is a copy of my current conf file:

Port 2121
BindToDevice eth0
ResolvLoadHack wontresolve.doesntexist.abc
User frox
Group frox
WorkingDir /var/cache/frox
 DontChroot Yes
LogLevel 20
LogFile /var/log/frox.log
PidFile  /var/cache/frox/frox.pid
BounceDefend yes
 CacheModule local
 CacheSize 400
 CacheAll no   # Set to yes to cache non anonymous ftp downloads
MaxForks 60
MaxForksPerHost 4
ACL Allow * - *

I need to run a WebDAV server inside of an LXC container, but I'm being told that modprobe is not available (even as root). I've seen that this was requested by developers, but how can I get around it?

Running on Debian Squeeze.

Here's the messages I'm getting after loading dav2fs on the main server:

Please enter the username to authenticate with server

I'm running two milters on my current postfix installation. I'm noticing that, from one particular client, they are sending an invalid command consisting of the first 3 letters of their domain name. When postfix sees this, it causes my milters to exit out.

How can I proceed past this?

I've seen this on the postfix documentation, but am not sure how to apply it:

milter_unknown_command_macros (default: see "postconf -d" output)
The macros that are sent to version 3 or higher Milter (mail filter) applications after an unknown SMTP command. See MILTER_README for a list of available macro names and their meanings.

This feature is available in Postfix 2.3 and later.

Thanks

I have a Linux server currently running under a Microsoft Virtual Machine. I have it set up so that the storage drive is set up as a secondary virtual disk. I need to move this machine to a new box running LXC, but storage is tight. I'd like to use my NAS for the storage drive, but it is currently formatted as NTFS for a number of other applications in my environment, so I can't link a folder to the NAS and keep the necessary permissions to run my Linux-based application.

I've thought about using TrueCrypt to create a virtual drive that is stored on the NAS, then mounting that under my Linux VM. Would this be a valid method to use, or am I asking for trouble.

Also, would using a loop device stored on the NAS be a better option?

Recommendations are very welcome.

I'm starting a Python script that I've created using start-stop-daemon. It works perfectly in all cases, except when I've forgotten that I've already started it. It creates a new process, but is unable to kill the old processes automatically.

Here's the complete script:

PYTHONPATH=/usr/lib/python2.4

# path to app
APP_PATH=/var/spool/EARS

# path to paster bin
DAEMON=/var/spool/EARS/pymilter_test8.py

#DAEMON_OPTS=" serve --log-file <my logfile> --server-name=main production.ini"

# script name

# pylons user

        echo "Usage: $N {start|stop|restart|force-reload}" >&2
        exit 1

Is there a way to have it check? I've tried the -S switch with no luck so far.

Thanks.

I have the following script that works on a local system, but not on a web-hosted system (where it needs to be). Locally, it downloads the file with no issues. When hosted, I get either zero- or low-byte files instead of the entire file.

<?php

$username = "user";
$password = "password";
$server = "ftp.domain.com";
$path = $_GET['p'];
$filename = $_GET['f'];

$file_full = $path."/".$filename;

$file_path = "ftp://".$username.":".$password."@".$server."/".$file_full;
$fsize = filesize($file_path); 

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer"); 
//header("Content-Type: $mtype");
header("Content-Type: application/octet-stream");
//header("Content-Disposition: attachment; filename=\"$asfname\""); */
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Transfer-Encoding: binary"); 
header("Content-Length: " . $fsize);


// download
// @readfile($file_path);
$file = @fopen($file_path,"rb");
if ($file) {
  while(!feof($file)) {
    print(fread($file, 1024*8));
    flush();
    if (connection_status()!=0) {
      @fclose($file);
      die();
    }
  }
  @fclose($file);
}

?>

My host provider is Hostmonster (if that helps at all).

In case you're wondering, I know I can just download links via FTP, but I need to force the user to choose whether to "Save As" or "Open", hence the script.

Assistance needed with a global procmailrc file
Creating a global procmailrc file that forwards to an Exchange server

++++++++++++++++++++++++++++++++++++++++

Please close, as this now a duplicate

++++++++++++++++++++++++++++++++++++++++

I'm new to procmail, so please be forgiving.

I have a postfix server on my network that (eventually) will receive a bounced message from our Sonicwall Spam Filter when a message attachment exceeds a certain size. The postfix server is configured to create mailboxes based on LDAP (using usernames from our Active Directory).

I need to create a global procmailrc file that saves the attachments to a folder, removes the attachments, then forwards the original message sans attachments to our Exchange server along with some additional text. I have the postfix server configured to handle our e-mail addresses ([email protected]), as this is a requirement of the Sonicwall when it bounces.

I've been working on this for a few hours, and I haven't even gotten to the point where a message sent to my postfix server gets forwarded to the Exchange server.

Please let me know if I'm being clear on what I'm trying to accomplish. I'm more than happy to elaborate.

Also, let me know if I should move this to ServerFault.

I need to forward all messages received on one server to another server (Exchange box). I know how to forward for an individual, but I am unable to forward for all addresses to their respective destination. The usernames are all the same, as is the domain name.

I've seen tons of documentation online for user-based procmail files, but global procmailrc documentation is scarce.

Again, this is for a GLOBAL procmailrc file that will affect all users. None of the recipients have home directories on the Linux box for which I would create individual procmail files (which is also an administrative nightmare).

EDIT:

To sum up - how do I create a global procmailrc that forwards mail for all users?

I have an FTP server set up where, off the root, there is a file structure laid out by city. Underneath each city's folder are more folders organized by project. I would like to be able to restrict my guest users (using a specific login/password) in such a way that they are unable to view the folders under the city name, but instead have be brought directly to them via an FTP link.

Example:

/
--City1
----Project1
----Project2
----Project3
--City2
----Project4
--City3
----Project5

link: ftp://ftp.company.com/City2/Project4
