Debian Configuration :: Winbind / Samba Authentication Causes Segmentation Fault
Apr 26, 2010
I added my linux server to a windows AD using winbind / samba. Everything worked just fine. After changing the OS to Debian lenny x64 I get a "segmentation fault" when trying to change user passwords. I am using the exact same configuration, on my 32 bit Server everything works.
debian:~# passwd <user>
sgmentation fault
tail /var/log/syslog:
kernel: [689689.005934] passwd[11209]: segfault at 0 ip b7b84418 sp bfc37fc0 error 4 in pam_winbind.so[b7b7e000+b000]
Debian Lenny 5.0

I've been searching around the web for help and have been really pulling my hair on this one. I have a Windows 2003 Server w/ AD on it. I have two linux machine, both running the same version of RHEL 5 (compute-1, compute-4)
When I log into compute-1, and do an "id dhuynh", I get this:
uid=1501(dhuynh) gid=1500(domain users) groups=1500(domain users),2013(dusers),1501(certsvc_dcom_access),1507 (BUILTIN+users)
When I log into compute-4, do do the same command, I get this:
uid=1500(dhuynh) gid=1504(domain users) groups=1504(domain users),1505(certsvc_dcom_access),1501(BUILTIN+user s)
Notice that the uid and gid are different. How do I get them to be the same? This is affective the file permissions in certain shared directories. I've check /etc/samba/smb.conf and they are identical. I also check /etc/nsswitch.conf and they are identical too.

VLC was behaving weirdly recently and when I've tried to run it with primusrun command (since I have optimus card) it gave me a segmentation fault
Code: Select allVLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision 2.2.1-0-ga425c42)
Segmentation fault
I've read on google that issue has been solved by a few people from updating the microcode, but I don't even understand what microcode is, I'm also not sure whether I should install amd64 or intel package for it?
Here is my lscpu
Code: Select all$ lscpu
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3

I'm running debian 8, no problems, after I recently upgraded some packages, skype did not open, I used terminal to open it and it gave an output saying
Code: Select allSegmantation fault
Then i opened it as super user and it gave this output
Code: Select all(process:1500): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

I noticed weird behavior with some of the installed applications. It all started with Guake when I wanted to use it. My shortcut key is F4, I hit F4 and nothing showed up. So I run Guake in terminal, everything fine. Then I hit F4 key and after few seconds Guake crashes with message "Segmentation fault". Nothing more, just that. Then I noticed that Audacity does the same, Gdebi too and even Reportbug app does that (I'm not sure about "segmentation fault", but the app crashes). I don't remember doing anything special or installing any app. All I can think of is this message when booting the system
Code: Select allsystemd[1]: Job rpcbind.service/start deleted to break ordering cycle starting with basic.target/start
No idea, if there is any connection. Is there anyway, how I can maybe see more behind that "Segmentation fault" error? I found history.log in /var/log/apt/, so I'm thinking about looking into it and see if I really did not installed anything. I have a little feeling that it might have started after some update, but I'm not sure about that..

Running programs in X (WindowMaker) as another user.
Until recently (Debian Stretch) I was able to run graphical programs in X as a second user, like so:
- log into X as user1
- run "xhost+"
- run "su - user2"
- run any graphical program (gthumb, konquerer, ...) as user2
Now when I try to run a program as user2, I get
Code: Select all user2@localhost:~$ gthumb
error: XDG_RUNTIME_DIR not set in the environment.
Segmentation fault
XDG_RUNTIME_DIR for user1 points to /run/user/1000 which I believe gets created by pam_systemd when logging into X. However, doing "su - user2" does not create /run/user/1001. Why not? And how do I get on-the-fly user switching working again?
Related to this, /run/user/1001 not being created on user switch has always caused me some grief b/c audio would not work for user2. But I could work around that by piping pulse through a socket. But now graphics are also broken and that I can't seem to work around.

I have discovered that epiphany cannot be launched.

If I click on either from the desktop, nothing happens. Doing it from a terminal, I get the following:

I would like to add a new user with useradd (on Debian 4.0), I get the message Segmentation fault. I made a strace, that says: access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) I have read maybe the libc6 is missing or damaged, so I installed it again (apt-get install libc6, install was successfull), but the problem is still there. I touched it (touch /etc/ld.so.nohwcap)

A few days ago I bought a Raspberry PI B with Debian Wheezy (7.0 - I think) on it. Before installing a media centre on it I wanted to do some basic configuration/upgrade and decided to upgrade to Debian Jessie. I followed the instructions provided on [URL] .....
Before moving to Jessie I have upgraded the original Wheezy; after the upgrade the version was 7.8. Everything went well till I executed "apt-get dist-upgrade". Errors where generated. As suggested I tried the "apt-get -f install"; but it did not go smoothly either. However, so far, I am accessing the desktop and everything seems fine (although I did not do anything fancy yet). The version recorded is 8.0. Thus, should I worry about the error messages generated?
Please find the log file here: [URL] ......
Note that I put the log file on Google Drive because each time I clicked on "add file" in the "Upload Attachment" tab when editing this message I got:
Internal Server Error:
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, forum-admin@forums.debian.net and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

I had Skype debian_2.2.0.35-1_amd64 on my Debian 2.6.32-5 amd64 and it was working without any problem. After re-installing my gnome desktop environment, my skype stopped working. I tried to re-install it. I found out it re-installs without any error but it doesn't launch and gives me "segmentation fault" error on terminal. I purged skype, deleted the .skype folder and installed it again with no luck. when I try to re-install skype via software center it says: "Sorry, 'skype' is not available for this type of computer (amd64)." what should I do to have the skype working on my system again?

How do I turn winbind authentication off or vsftpd. I keep getting these error messages in the /var/log/ secure:vsftpd: pam_winbind(vsftpd:auth): request failed: No such user, PAM error was User not known to the underlying authentication module (10), NT error was NT_STATUS_NO_SUCH_USER.I already tried remarking out different things in the config files. Is it safe to remark out the winbind stuff in /etc/pam.d/system-auth if we are using the smbclient to connect to a Windows share?Why would you want to to use AD to authenticate users for something simple like FTP is beyond me.I merely want it to authenticate against local system users.

I did a Yum update last Friday. It was done before 5.6 was released so I still have 5.5 + various updates. Yum is now giving me a segmentation fault when I try to run it. I believe it has to do with an improperly synchronized version of sqlite which was updated and then Yum stopped working. I'm guessing that installing the latest Yum RPM will fix the dependency issues. Will this throw me out of sync with for instance updating to 5.6?

Some time ago I had to reinstall all my packages under 64-bit OpenSuse 11.2. After that I can't get Skype working - Skype always gives me "segmentation fault" when trying to execute it (from command-line).
I've followed steps recommended in wiki, I've tried different versions (32-bit as well as 64-bit RPMs) downloaded from different repositories (including old 1.4.0.xx). Nothing changes anything.
I don't have any webcam and I've never had one, so I guess it cannot be related to that.

I have not found any solutions that would solve my problem yet. Every time I try to load a website including flash advertisings, Firefox just quits.
All the time I get this output.

I am programming an application with an ARM device with an embedded version of Linux. My application talks to a java application via socket. If there is any connection problems, it attempts the connection again. My problem is that after exactly 146 times, there is a Segmentation Fault. Apparently this happens in opening the socket, which is not successful after this amount of attempts.
Following, some code that I'm using:

I have a problem with a directory which contains my music collection. It can't be opened; all other directories work fine. I can cd into my ~/Music directory, but ls gives segfault and KDE programs hang when trying to open this directory. The problem probably has appeared after the rename of subdirectory under the Windows (don't remember particular ext3 driver; can check tomorrow).fsck says that the partition is fine. The whole disk is mounted on the single partition. Windows is located on another physical disk.Is there any way to recover my directory?

I have a centos server running nagios for monitoring. I restarted the machine, it is actually a console server anyway. After getting to the login screen, I typed in my user name but it never propt for my password. I can't even ssh into the system. So I tried to use the installation cd and enter into rescue mode where I typed chroot and was able to enter into the root environment. I was able to configure a network interface in the rescue mode and can ping the machine at this point, though can ssh still. In the root environment, I tried running couple commands. like try to restart the sshd. When I typed /etc/init.d/sshd restart, I got an error saying:
766 segmentation fault.
when I vi any thing I get error:
segmentation fault.
how can I solve this problem? What is causes this. Even in the event of restarting the machine, I see so many fails with segmentation fault.

When I compile my C program on SUSE, I receive a segmentation fault error. To my knowledge, this occurs when a program tries to recall memory but is not allowed to. So I'm using GDB for the first time to solve this problem. After a series of commands, I reach this point:
Code:
#0 0x00002b13e1bab127 in getdelim () from /lib64/libc.so.6
#1 0x000000000040167b in main () at dmsp_cusp.c:158
Here's the offending code in dmsp_cusp.c:
Code:
157 printf("enter the input file name:");
158 getline(in_fname);
159 fp3 = fopen(in_fname, "r");
160 if(fp3 == NULL) {
161 printf("can't open input file %s",in_fname);
162 exit(1); }
