I'm on Ubuntu 12.04 via Amazon EC2 and compiled and installed jailkit from source. It's a fresh installation so I don't think anything is out of place. I'm trying to enable debugging now in jk_chrootsh.c and then will recompile it and see what happens. In this section (line 206 of jk_chrootsh.c) if (strcmp(tmp, PROGRAMNAME) != 0 && strcmp(tmp, "su")!= 0 && (tmp[0] != '-' || strcmp(&tmp[1], PROGRAMNAME))) { DEBUG_MSG("wrong name, tmp=%s, &tmp[1]=%s\n", tmp, &tmp[1]); syslog(LOG_ERR, "abort, "PROGRAMNAME" is called as %s", argv[0]); exit(1); } it seems odd that "tmp" is set as "-su" instead of the expected "su" and that tmp[0] I believe is set as "su" when I am trying to use "su - jane" - like some of the variables got shifted or offset. I was also looking for a link to the jailkit source to try and see what has changed in that block of code over the last three releases. |
