linux – fluentd will not send logs to Graylog using the input gelf udp

I run fluentd in a container and logs are mounted using volumes in this container. The problem is that fluentd does not send logs to Graylog. I have configured the fluentd.conf file accordingly. When you run the container, it displays this:

 2019-10-14 14:04:01 +0000 [info]: starting fluentd-1.3.2 pid=6 ruby="2.3.3"

The fluentd.conf file

 
  
    @type gelf
    host 136.243.6.94
    port 12201
    flush_interval 5s

  @type tail

  path /var/log/apps/pm2/log/server-out.log
  tag graylog2.server-out
  pos_file /var/log/fluentd/server-out.pos

Any help would be appreciated.

Remotely exploit the Linux kernel with CVE-2017-18017?

I have configured a server running Linux Kernel 4.4. How can I exploit this, preferably not a denial of service attack? I've opened port 80 (https), but I'd prefer to do it in an elegant way so I can learn something rather than just run without thinking while running slowloris. A specific vulnerability that I have looked at is:

CVE-2017-18017

Thank you, c0mraide

linux – Cloudfront and Apache 400 return code

I currently have the following configuration with AWS Cloudfront:

ME –HTTPS -> AWS CF –HTTPS -> AWS ALB –HTTP -> EC2

Even though I am able to recover the index file from my EC2, whenever I try POST, in a connection form, I get 400 in my Apache logs.

10.0.0.192 - - [12/Oct/2019:22:04:23 +0000] "POST /users/login HTTP/1.1" 400 5383 "https://my.custom.domain/users/login" "Amazon CloudFront"

My Cloudfront distribution is also configured to pass all HTTP methods, including POST. My ALB is configured to switch to my TG which has all instances in good condition.

My EC2 instances are not configured for 443 and my vhost for 80 allows rewrites.

Can I miss a proxy configuration in Apache to support these requests?

linux – How can I make sure that the server can handle the load of new users in the email marketing tool?

My situation is that I have just taken over a web team that hosts all of their clients' websites using a server provided by Clook

Web sites have a feature that allows client clients to subscribe to a mailing list via a web form. The customer will then be able to connect to the marketing tool, Interspire Email Marketer, and send emails to anyone who has already done so. subscriber.

EM (Email Marketer Software) is installed on the Clook server and is currently used without any problem. However, we plan to add 300 to 500 additional users to EM and I have to make sure that the server can handle it and that it will not suffer any negative impact. We can not afford to try with errors because ALL our websites are hosted from this server and it will be expensive for these sites to disappear.

I am very new to the server business. So I wonder if anyone can advise me on what I need to check and how I can make sure we can add these new users without any problem.

I've already looked at the server specifications: 7-core processor, 9216 MB memory (does not specify what type of memory it is), 220 GB SSD, 100 MB port speed. J & # I have access to the server, so I can check other information if necessary.

Any advice would be great, thank you.

For example, it's like that
A B
C D

But when I convert it to excel, A and B are in the same columns

I want A and B to be two different columns

How to convert it by excelling by displaying the output on two columns?

linux – Email sent by an outsourced application returns a host error when it is sent to the same original domain name

I have a customer who has Plesk Onyx and they've given me their credentials to check the problem they're having, but they do not seem to be able to detect it.
I do not know the version of Plesk because my account does not have access to tools or settings.

We have connected their mailboxes via SMTP and IMAP / POP3 to the CiviCRM website they use, in order to send newsletters.

The e-mails are sent via the newsletter, but when they send e-mails to the same domain name (their colleagues for the tests, for example from info@example.com to bob@example.com), they are returned with a HOST syntax error. Does anyone know what could be causing problems?
