unix question

 [1/8] from: fantam::mailandnews::com at: 2-May-2001 1:56


Hello all, How do I launch a rebol process on a remote unix box that is to survive my telnet session, i.e. it should continue to run after I log off (I'm no administrator). Thanx in advance, fantam

rebol myscript.r & works for me with /core 2.3 on Solaris If that dosen't work on your unix you can add -nohup

I was just about to propose that, but it /isn't/ working for me with Rebol/View 1.1 on Solaris at the moment. Odd. --Scott.

That's because /view is attched to a visual i.e. it requires an X client to display itself. X clients are usually closed when you exit and so your /view session is also killed. For /core as it does not require a visual it can exist after a logout using & and/or -nohup. You can preserve your X client using the VNC technology.

Thanks for the useful information. My next concern is how to make sure the rebol script is relaunched after a reboot, bearing in mind I'm just a user on the system (no administrator). fantam

A question for the unix ppl out there: Do you need admin rights on a linux box to install and execute rebol. I installed rebol succesfully, but it doesn't run. I suspect it can't access the libraries (libc5 or libc6). Does this make sense? Here's what's happening: $ uname -a unix sdf 3.2.2 3 3B2 $ ./rebol *** Boot Error 951:

No :-). If REBOL had problems accessing the libraries then you would get an error from the Linux loader, i.e. REBOL would not even get to the point where it could display a boot error. You do not need admin rights to install REBOL.

This looks like either fork() failed (i.e. REBOL is unable to create a subprocess) or REBOL cannot open a socket in the "unix" ("local") domain. REBOL needs both operating system features for internal communication. AFAIK all Linux versions support local sockets, because they are needed for logging, i.e. the more likely problem is that fork() failed. If the Linux box is at an ISP then the sysadmin may have restricted your rights to spawn subprocesses to avoid denial of service attacks. In that case you need to talk to your sysadmin and have them ease those restrictions. -- Holger Kruse [holger--rebol--com]

Thanks, Holger, that was enlightening.
