Hi Emmanuel,
you can always configure conserver to do a "ssh <softioc-host> telnet
localhost <softioc-port>" if you prefer not to run the conserver-server
on the soft ioc host itself.

Opening up the telnet port to a linux hosted soft IOC opens up a severe
security hole, as everybody can connect to the IOC console and might be
able (using the "system" command in IOCshell) to execute arbitrary
commands on the host machine. So I'm a bit reluctant on that issue.
Maybe I add a compile switch enabling an additional command line option?
Maybe rather not?
I have noted your other request and will add the corresponding option.

Use the -i (--ignore) option to block unwanted characters. For soft IOCs
I suggest using "-i ^C^D" as ^D will also stop (and restart) the soft IOC.

BTW: This is described in detail on procServ's one page html
documentation. (procServ seems to be not simple enough...)
Tech-talk-readers: This refers to enhancements to procServ (originally
written by Dave Thompson at SNS), that I'm going to release and publish
later today (maybe Monday), after adding Emmanuel's suggestions. (I sent
him a pre-release tar for real-life beta-testing.) Stay tuned for a moment.
Cheers,
Ralph

I am now using a procServ/conserver configuration.
One of the issue is that the procServ allow only connection from
localhost (telnet localhost <port> ) as a result the conserver master
for the associated console should be the host on which procServ is run.
I have noticed that procServ respawn the process if killed (or crashed?)
is there a way to control the respawning of process without having to
recompile procServ? Apparently there is no command line option to stop
that behavior or to configure it.
procServ is simple and straightforward.
Perfect for simple minded people like me ;-)
I noticed that Crtl-C kill the child process.
Is there a way to prevent this?

I recently looked at conserver.
It is great for logging terminal outputs and getting IOC access from any
authorized host.
I believe some of you use this application to start IOCs.
How do you start the IOC in the first place? manually?
Is there a way to start the IOC manually but in detached mode?
There is probably a combination of screen/conserver that does what I
want...
