After todays dist-upgrade when executing the "sux" command to switch to root, the following message is printed after authentication:
$ sux
Password:
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
Maybe this has to do with a modification of /etc/login.defs that I think the package "login" asked me to let it do. It did change an entry "ENCRYPT_METHOD SHA256" to "ENCRYPT_METHOD SHA512" IIRC.
As I do not know if this is critical or not, I do not post this in the dist-upgrading warning forum.

Same here only with sux, not with su. Unfortunatelly I cannot offer a solution but reverting to the package "login" from testing.

Did that correct the problem? if so maybe a bug report should then be filed to correct the package |

I'm a bit confused. The problem is with login/password 4.1.5-1 and login/password 4.1.4.2+svn3283-3 is not affected, is it?
If all the above is true, why 4.1.4.2+svn3283-3 is not any longer the testing version?
Or is this like a prescription drug? 4.1.5-1 is not the solution, but it has better side effects than 4.1.4.2+svn3283-3 ?
I still have4.1.4.2+svn3283-3, should I hold both login and password, or upgrade to 4.1.5-1
Thank you |

| Maybe someone could describe what the real problem is. I see the bash messages, but what negative effect does it give? Any commands I have issued seem to work as usual. |

| There are two problems I have with the sux-shell: Pressing Ctrl+c does close it, instead of just ending the running command. Also a logout requires some (6-10?) seconds, as it is waiting for the sux-shell to end. |

su does not suffer any problem/limitation
sux was conceived as a wrapper around su with transfered X credentials so the main purpose is/was start a X application as root ( is that really needed?)
the changed was due to a security leak http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659878#10 caused by the sux not su so sux got limited capabilities...
just one proposal: use su not sux ( use the last one only when you want to start some X appl and not as a root shell)
Advantages: you spare one letter (x) when becoming root and avoid the (actual) underlying probs. |

Despite the warning, sux still works. I use it in "ssh -X" sessions with a remote computer when I want to access GUI applications as root. Aptosid only on all boxes.

Using su instead of sux helps regarding the error message. Also ctrl+c is possible again, without exiting the bash. So I will use su as long I do not need the x. Thanks so far.
But the issue of konsole hanging for some seconds when logging out from KDE also happens with su. |
