Enter PEM pass phrase: #10

Closed neggert closed 12 years ago

neggert commented 12 years ago

I'm often prompted to enter a PEM pass phrase when trying to copy a file from a storage element. Sometimes I'm asked for every file. This is quite annoying when I'm trying to copy every file in a dataset using a for loop.

How you'd like to handle it? Should I introduce a new passphrase command which will store it? Since the passphrase is asked by GRID middleware tools, I can wrap the call with echo, e.g. echo | srm-cp I think it will work.

I guess my question is, why does it only happen sometimes? I just quit cmssh, restarted it, and tried to copy all the files from the same dataset using the same commands, and it never prompted me for a password. To me that indicates that it's possible to do this without the raising the prompt every time, it's just a matter of figuring out under what circumstances the prompt appears.

Ahh, well, that because at startup of cmssh I invoke voms-proxy-init command which setup a proxy from your certificate. This proxy has limited lifetime and needs to be renewed. Therefore you have additional commands vomsinit, vomsinfo, etc. You can use them to renew your proxy. But I think I can run additional thread to do that for lazy users :)

Ah, no problem. I can run them manually. I just wasn't sure how to do it manually.

I've added voms_monitor which will renew user proxy. Closing the ticket.
