comment Run two daemon jobs in two different directories
Your question is basic but more importantly it's not well defined, it is vague. Believe it or not the OS matters and to some extent so does the scripting language. Do the daemons take arguments that tell them which directory to operate in or do they assume the current directory? Do the daemons produce pid files? the list of questions goes on.

comment cron job sending emails in a wrong charset
I don't think we're going to be able answer this directly, you'll have to work out what is missing from the cron environment yourself and add it. This answer will help you setup an cron-like environment that you can work in.

comment How to grant user modify only specific protected file by sudo
/etc/hosts does not normally have execute perms so putting a shebang at the start won't normally have any effect.

comment Backplane of a switch
This question appears to be off-topic because really, read the specs for the device in question. Somebody went to the trouble of working it out and documenting it for you.

process/client be configured for dynamic DNS and for it to be working correctly. To be honest this whole question smacks of homework. It's the kind of vague question a professor gives people to make them go out and think. If it's not then you really should be engaging with your clients network team to find out more about how the can help you achieve your clients requirements.

comment Restrict Access from certain machines to my Web Application in LAN
We didn't prove you are an idiot. The clarifications we requested were because your question was vague. It seems a little clearer now but to correctly answer it we still need information you have not provided. To have your application block a remote machine the application needs to know something about that machine. It can't know it's mac address as that isn't passed that far up. Your application server may be passed the IP address of the client. You could use this but to do so would require that the DHCP ...

$(ls ...) isn't required, the shell will expand ${DATE_MAX}_* correctly in it's own.

Token Ring - really that's very unusual today. Yes, what you want to do is entirely possible in a modern network but how would depend upon the current infrastructure, OS etc. With token ring I really wouldn't know.

Your question is vague. Tell us something about the LAN topology and the switches in use, the client OS, the server OS, DNS, what the server is etc. What is the budget for this ?

comment What is serving my nginx on the docker?
Just to be clear - this isn't the site for you. We generally expect that people who are professionals within system administration to have some skills which you clearly do not.
