Title: red core?
Post by: Alejandro on March 08, 2001, 04:51:08 PM

HI all!
Yesterday I was browsing the e-smith box with midnight commander... checking things and configurations bya a ssh root connection i opened one or two files in diald and then when i closed the file without saving (i was in the viewing mode)misteriuouly appear a file named "core" colored in red in the panel of mc.
Any Ideas?
nobody was using any services at that time.... so I dont have a clue! (my concern is a virus)
The file was in code son nothing to guess.

Any help would be very kind

When a program crashes in unix, the OS dumps information about the state of the program into a file called core. One can then later analyze this file for debugging purposes. You're probably safe to just delete it.

I'd first identify which program has the bug in it (i.e. which one crashed). You can do that from the command line using:

file /path/to/blah

(where blah is the file). If you are in the same directory as the file, do:

file blah

thanks Emmanuel and Charlie.
I will do what you say
I guess it could be ssh...?
it was a ssh internal connection to the server where I was using midnight commander.
then I will add a new post with the results.
