 Posted: Fri Oct 10, 2008 3:18 pm Post subject: Gentoo Installation SU problem |
 |
|
Hello again,
I've already mentioned this problem but I haven't got to much solutions.
I ask a Developer to Install Gentoo in a box and reproduce the same error as I have, because It's NOT tolerable.. I want a solution and I want it A.S.A.P., because I have serious problems at my Office with this, and I cannot reboot the system every time I su-
| Code: |
# su - admin //root shell
$ llogout // normal shell
# // root shell again
|
When I SU in another simple account, the first time works fine, but the rest, each time I type something it throws me out of the shell with a "logout" command...
If I hit a couple of Enters, it works fine:
| Code: |
# su - admin //root shell
$ //here is an enter
$ ls // any command works
$ exit
logout
# // root shell again
|
Please Advice, this is terrible, please recompile bash on a test box to reproduce the error, check the portage for a younger Bash, DO SOMETHING please, this is terrifying ! I can't work like this
Thank you, and please, RESPOND...
Edit: the same problem can be found here: https://forums.gentoo.org/viewtopic-t-708761.html
I've posted it because it is also an installation problem, the same version of bash is on another computer of mine, and that works well...
Please do everything you can think of to resolve this problem ! |

admin:x:1000:100::/home/admin:/bin/bash
It is a global problem, with every user I might add...
If I hit a couple of enters, everything works... if not, bash automatically logs me out when I start typing one letter |

That looks in order, go ahead and emerge pambase
then run env-update && source /etc/profile
login to another shell and test. |

Okay, what is the output of echo $- like this | Code: | # su - admin //root shell
$ //here is an enter
$ echo $- |
Also does this produce any output? | Code: | | grep onecmd /home/admin/.bash* |

Hmmm. That is ok also. Try re-emerging bash - but never unmerge bash. | Code: | emerge --sync
emerge bash |
Also post output of | Code: | | # cat /etc/skel/.bash* |

Reinstall of Bash did not solve the problem...we have the same problem: 1st time working, 2nd time not

Well that's different. I was assuming that it was a regular session on a normal Gentoo.
If you open a thread something like "PuTTy SSH Login problems" in the Networking & Security forum, and explain the context, I'm sure you will get the proper assistance.  |

Hello again,
I've already mentioned this problem but I haven't got to much solutions...
At the advice of a Veteran Member, I've posted here in the Networking Category.
Problem happens in Network Enviroment (when I use putty to ssh on the server) and on Local Login (TTY).
I ask a Developer to Install Gentoo in a box and reproduce the same error as I have, because It's NOT tolerable.. I want a solution and I want it A.S.A.P., because I have serious problems at my Office with this, and I cannot reboot the system every time I su-

If I hit a couple of Enters, it works fine:
| Code: |
# su - admin //root shell
$ //here is an enter
$ ls // any command works
$ exit
logout
# // root shell again
|

Some things you can try:- PuTTY into another *NIX box and then SSH root from there
- PuTTY as a simple user then su - and su - admin
- EDIT: try su'ing without the hyphen
- Install app-admin/sudo and use that instead; what does that produce?
- what does scp to/from the problematic host do?
- Check another remote shell than PuTTY.
It's all I can think of for the moment.

| I never, ever have used the " - " option. I've also never, ever have had a problem with su. It just works. Maybe it's an issue with putty? |

SSH from another box is working, su- from other user accounts is working, the only case this is happening is if Root Sues into a normal user account.
Both "su -" and "su" commands are the same, with a small diference I won't detail now... but in both cases it logs me out on first typed letter.
This is deffinetly a server problem, not a client one |

Since this is reproducible, I suggest logging system calls using dev-util/strace. If that does not yield anything interesting, rebuild the shell with debug symbols and monitor it with sys-devel/gdb.
I routinely use su - user to switch down to unprivileged users for temporary work, and have never seen a problem. Since you neglected to provide any information whatsoever about your system, it is rather unlikely anyone will be able to reproduce your problem. At a minimum, we need to know your architecture, compilation options, and which shell is used by that user. Start with the output of emerge --info ; grep admin /etc/passwd ; equery list app-shells/. |

I tried logging with the system logger, but in this case, the problem does not happen:
| Code: |
maincore ~ # strace -o log.txt su - admin
admin@maincore / $ pwd
/
admin@maincore / $ ls
arhivum backups bin boot deskbase dev etc home lib lost+found mnt opt proc root sbin sys tmp usr var
admin@maincore / $ logout
maincore ~ #
|
I can type and the shell does not exits me.... this is very odd... it only happens on plain "su - admin" ... |

I tried on another server, the problem is GLOBAL, repeat, GLOBAL, on all servers, not only on mine, and can be reproduced:
Try logging in directly as Root on TTY1 or SSH and SU into a normal account. The first time it will work, but the second time not.
IT IS A GLOBAL GENTOO PROBLEM !
Also, this is very strange:
| Code: |
infosky ~ # su - admin
admin@infosky ~ $ ls
agenda mail
admin@infosky ~ $ logout
infosky ~ # su admin
admin@infosky /root $ exit
infosky ~ #
|
As you can see, if I su with - , it allows me to remain on the shell, If I su without -, it automatically logs me out without typing anything.
| Code: |
infosky home # cd /home/admin/
infosky admin # su admin
admin@infosky ~ $ exit
infosky admin #
|

No, happens with openssh too, and the problem lies in su or bash. I have this problem on one of two remote machines when I: | Code: | me@here$ ssh there
me@there$ su -
root@there# su - user
user@there$ {type first char of command}logout
root@there# |
where the "logout" is added by the machine as it boots you out of the shell. If I type a "space<enter>" then the user@there shell works fine. Both the "here" and "there" machines are Gentoo, stable, and up-to-date. The "there" machine was installed recently from profile 2008.0. The "here" machine and the working remote machine are now 2008.0 profile but have been update to that from 2004 and 2005 vintage installs.
I had it working by rebuilding all the dependencies of "su" and "bash" the two programs directly involved | Code: | | #emerge -e sys-apps/shadow app-shells/bash |
I thought it was gone for good, but it happened again yesterday. Intermittent race condition or something?
