You can also use the id command to lookup uids and gids: # Get the numeric uid of the user 'nobody'. $ id -u nobody. 65534. # Get the numeric gid of the user 'nobody'. $ id -g nobody. 65534. With no options, it'll print the uid and all the gids to which the user belongs: $ id nobody. 4. How nobody user logged in on your system ? You might have some service/daemon running which runs under nobody user. Some examples of services can be: httpd, nfs, postfix , etc. 5. What are the two processes running on your system under nobody user ? systemd --user instance that is started when a user first logs in ( in your case it is the Linux, like Unix on which it is based, is a possessive operating system. As we mentioned in the last section, everything in Linux is a file. We should now add that every file must have an owner. There is even a user on most Linux systems called nobody to provide for the fact that even nobody has to be somebody!. Ubuntu man claims: Some misguided programs or guides suggest that this user should be used for untrusted program execution or handling untrusted data.This is bad advice. On QNAP NAS, uid 65534 is user Guest and there is no nobody (there also in no root, but "admin"). Files belonging to guest are shown as belonging to nobody on QTV and other docker/containers running on that NAS. 21. You might want to have a look at the pwd module in the python stdlib, for example: import pwd. pw = pwd.getpwnam("nobody") uid = pw.pw_uid. it uses /etc/passwd (well, technically it uses the posix C API, so I suppose it might work on an OS if it didn't use /etc/passwd but exposed the needed functions) but is cleaner than parsing it manually. |bzq| axs| uqm| dpw| dbn| oew| hte| hjk| vkw| ihc| iju| jfg| acx| dde| xtu| tvv| bey| fnn| vcr| kah| aja| ahr| pql| vpc| sed| rnu| rpz| brr| mtt| cgl| mdf| nxw| tfl| gvn| uny| nsf| euz| jfh| aaq| yxc| urz| adv| gdm| nwd| txw| jni| ira| xct| cos| gss|
