I created a suse linux enterprise 15 vm in GCP. When I try to install anything it gives the following error.

I searched a lot but couldn't find default package repo for suse.

test-suse:/etc/zypp/repos.d # zypper refresh --services
There are no enabled services defined.
Use 'zypper addservice' or 'zypper modifyservice' commands to add or enable services.
Warning: There are no enabled repositories defined.
Use 'zypper addrepo' or 'zypper modifyrepo' commands to add or enable repositories.

Which is default repo for suse linux enterprise? I only want open source softwares like git, ansible etc.

Thanks in Advance.

I am trying to create a monit config file to monitor if mongodb is running.

Here's my config file.

check process mongod with pidfile /var/run/mongodb/mongod.pid
   group mongodb
   start program = "/sbin/start mongod"
   stop  program = "/sbin/stop mongod"
   if failed host 127.0.0.1 port 27017 protocol http
     and request "/" with timeout 10 seconds then restart

I always get the following error and it restarts mongodb.

  port response time           FAILED to [localhost]:27017 type TCP/IP protocol HTTP

I checked and verified mongodb running. I event tried connecting to mongodb using curl. Here's the command I executed to verify http connection to the mongo is working.

curl -v localhost:27017

Here's the output I am getting.

* Rebuilt URL to: localhost:27017/
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 27017 (#0)
> GET / HTTP/1.1
> Host: localhost:27017
> User-Agent: curl/7.58.0
> Accept: */*
>
* HTTP 1.0, assume close after body
< HTTP/1.0 200 OK
< Connection: close
< Content-Type: text/plain
< Content-Length: 85
<
It looks like you are trying to access MongoDB over HTTP on the native driver port.
* Closing connection 0

Not sure what I am doing wrong.

The same config file is working on ubuntu 14.4, but it does not working ubuntu 18.4.

I am having problem with my dovecot on CentOS machine.

The error message is as below.

server dovecot: dovecot: Time just moved backwards by 1 seconds. I'll sleep now until we're back in present. http://wiki.dovecot.org/TimeMovedBackwards

I checked the link provided in the error message, I don't have ntpd running(did ps -ef | grep ntpd).

I found one pattern which would suggest that this happens at 4:36/37 (AM and PM).

I checked if any cron that does the time correction. I checked log at this time in /var/log/messsages but could not find anything specific.

Please suggest me a way to find out what causes this time shift. Also let me know if any other info required.
