electricsheep issues

SeRi@lDiE · 08-29-2011, 07:26 AM

I been using electricsheep since its first days.... for the past few days electricsheep has gave me some weird errors...

Code:

detected another electricsheep process

And it goes in to read only mode....

I have found no solution to this issues and there is no logs behind....

Any ideas?

TIA.

Grab the source, and in the top source dir, run

Quote:

grep -rne 'detected another electricsheep process'

grok the source around there and see if you can see what the test is.

I grep the source tree with no luck.
Any other ideas?

TIA.

I found this block from the page here: http://electricsheep.sourcearchive.c...8c-source.html:

Code:

do_lock() {
    char fn[MAXBUF];
    int fd;

    struct flock fl;
  
    sprintf(fn, "%slock", leave_prefix);
    if (-1 == (fd = creat(fn, S_IRWXU))) {
      perror(fn);
      cleanup_and_exit(1);
    }

    fl.l_type = F_WRLCK;
    fl.l_whence = SEEK_SET;
    fl.l_start = 0;
    fl.l_len = 0;

    if (-1 == fcntl(fd, F_SETLK, &fl)) {
      if ((EAGAIN == errno) || (EACCES == errno)) {
          fprintf(stderr, "detected another electricsheep process.\n"
                "using read only access, ie disabling "
                "downloading of sheep.\n");
          read_only = 1;
      } else {
          perror(fn);
          cleanup_and_exit(1);
      }
    }
    /* leave the file open & locked until our process terminates */
}

Also found you are not alone: http://community.electricsheep.org/node/1408 among others googling the "detected another electricsheep process" error

jkirchner,

Thanks for your reply.

I guess I didnt grep correctly... lol

Yea I found some people out there with the same issue but none of them really posted a solution. I did removed the pkg and re installed it but that only lasted about 1 day when the error came back...

Arrggghhh this is aggravating... The problem is that it has been working for many years without an issue till now. and changing anything would not help. My system has not change for anything to brake.

I just found that for every time xscreensaver gets activated the following command spawns like 10 times....

mplayer -really-quiet -cache 8192 -monitoraspect 1920:1080 -fps 23 -vo vdpau -wid 0x4400042 -nostop-xscreensaver -

which is what could be causing the issue with electricsheep. Any ways to debug this?

TIA.

Well, as you can see I was at work and we have Windows....I scraped the code and used find in Notepad.... meh, it worked.

I saw the Slackbuild for it the other day and was going to try it... I had heard of Electric Sheep but never ran it....not sure if I want to now

I never had any issues with electricsheep. After I did killall mplayer looks like it clear the error. Lets see how long would it last.
I think is the best screen saver by far.
