UNIX for Beginners Questions & Answers

Hello Guys,

I need some help to find out if processes are running on remote server or not. I could do 'ssh' to do that but due to some security reasons, I need to avoid the ssh & get result from remote server.

Could you please suggest some that can be done without ssh or similar sort of utility ?

Greetings and welcome,

I don't understand why ssh ( which is what all admins want users to use for security...) is not allowed for security reason, how will you connect to remote server??
my understanding is you want to have a job running local on your remote host (using cron?) I suggest your cron job send an alert to syslog, there is on solaris and I think on other OS too a way of collecting the content of syslogs from remote servers ...

Bit vague requirement, processes must be running on servers

Using, for instance, local5.info facility and logger command inside a shell script.
You configure that servers syslog to send logs to your central syslog server for that facility on IP using UDP or TCP.

Central syslog server will receive / parse etc. the logs messages.
Great choice for server side is any OS that can run rsyslog, which is good software, highly customizable.
Benefits arise when using ZFS filesystems on BSD/Solaris and Linux, when using compressed file systems to store logs.

Be sure to read about maximum message length limits and stuff, so you do not get into surprises.

Hope that helps

1) use remote procedure calls: you will have to write a program, it will be insecure and, frankly, i wouldn't want it in my data center, but it avoids ssh.


2) use telnet (or is this too similar to ssh?). Otherwise, see above but without the neet to write a program.


3) use SNMP. There is a reason why "SNMP" is thought to mean "security? Not my problem!", but it avoids the dubious ssh either.


4) create your own network protocol, then write a client/server-application which uses it to transmit the information. Report back in a few years to show us.


Bottom line: if you don't want to use secure means to connect to a sever you have to employ insecure means. Furthermore, if you want to avoid the obvious you will be restricted to the absurd.
