Check for open ports on external server instances from the command line

Hi,

sry for this question.... I hope i am only blind.

Is there a possibility to check if an externe Port is open and reachable?

I try telnet and nc both are not installed and i am not sure it would be a good idea to install these pakages from an rpm file.

Using vRealize Log Insight appliance Version 4.7

greetings

Not sure what you're asking. Are you trying to check if a port is open on an external system from the Log Insight appliance itself?

Exactly,

the connection between my log insigh installation an the AD is not working.. there are al lot of posibilitys why it is not working..

The first thing i checked was the name resolution.. the next would be to check if the ip on the specific port is reachable by the log insight installation. For this i normaly use something like tcproute. In the case of vmware appliances this is not installed. So i use nc or telnet. But both are no installed on the log insight appliance.

Yeah, you can't upload those tools to a VMware appliance and start using them. But curl is there (among others) which can be used to troubleshoot.
