OpenSUSE Install :: Sshd Segfaults During Pam Auth After Upgrade From 11.1 To 11.3?
Oct 6, 2010
I'm testing upgrading from 11.1 to 11.3 and running into a major roadblock. When I try to ssh to the server after upgrading, I am unable to use password or pubkey auth to connect via ssh with my ldap user due to sshd segfault. I can however connect via pubkey to a local account on the system. Both auth methods work (for local users) when I disable UsePAM in sshd_config, but auth via ldap is required. My configuration works fine on fully patched installs of both 11.1 and 11.3, but not a fully patched 11.1 upgraded to 11.3. I've been at this for a while now trying various things but don't seem to be making much progress..

I've started to get segfaults in sshd when trying to connect. There has been no reboot and (until I restarted the sshd to try to fix the problem) there was still another ssh session connected.
The log messages:
Code:

If I ssh from my laptop (running F10) to the server (centos 5.2) it asks for the password, but everytime I enter the correct password it says incorrect password. when I do the same from the server to my laptop I can get in just fine. I think my passwords are stored as ssha in the LDAP (I tried clear passwords and that dosen't work either).

When I am closing yast, from time to time I get this error. Although something segfaults the system seems to behave normally and I do not experience other issues it seams. The error comes up in a small separate window. Yast stays operative. Should I be worried about something? What is the system complaining about actually? Although this happens quite often, it does not happen always.
System is: 11.1 with Linux linux-xu0v 2.6.27.45-0.1-default #1 SMP 2010-02-22 16:49:47 +0100 x86_64 x86_64 x86_64 GNU/Linux and KDE 3.5.10 (r87) Yast: 2.17.69-0.1.1-x86_64

So I have looked everywhere, I see the ssh script in /etc/init.d everything seems to check out with chkconfig (shows 3 and 5). But for some reason my SSHD server doesn't start on boot till I run either rcsshd start or /etc/init.d/ssh start.

I upgraded my processor two days ago(p4 -> C2D), and ever since then I have been getting segfaults, which are causing my programs to crash randomly. At first I thought it was isolated to one program(deluge), but after searching around I was looking at the /var/log/messages and found a bunch of segfault messages after I installaed the processor. Here is the grep from the messages file:
Code:

I'm trying to upgrade Karmic to Lucid. I open the update manager, click the "upgrade" button, and then again the "upgrade" button in the window that pops up. Then it just closes down. When running the update manager from a terminal, the only output is "Segmentaion fault".

I just upgraded from FC 13 to FC 14. I run an ssh server on a port in the 3000s (call it 3xxx, to protect the innocent). When I try to start sshd with the "Port 3xxx" option in sshd_conf, I get the following error in /var/log/secure
sshd[5104]: error: Bind to port 3xxx on 0.0.0.0 failed: Permission denied.
sshd[5104]: error: Bind to port 3xxx on : : failed: Permission denied.
I did not use to have this problem in FC 13. how I can give sshd the necessary permissions now?

I've probably exhausted all possible ffmpeg argument combinations for encoding with a libx264 codec - none worked, the codec always either segfaults or tells me incorrect parameters. I've installed, uninstalled and re-installed all available versions of the codec - no difference. Did anyone have any luck with it? Are there any tricks or conflicts in different arguments? Does the input file have to be in any particular container/format/codec for the x264 to work on?
My examples: >ffmpeg -i video.mpg -vcodec libx264 video.mkv >... Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height >ffmpeg -i video.mpg -vcodec libx264 -b 4000 -s hd1080 -f h264 video.mkv Same error If I use any other codec, they all work fine. give a working ffmpeg arguments example,

I'm trying to add the -audit option to X Server. I run ps -ef | grep -v grep | grep "bin/X" and get: root 2511 2506 0 10:35 tty7 00:00:09 /usr/bin/X:0 -br -verbose -auth /var/run/dgm/auth-for-gdm-sScn1P/database -nolisten tcp vt7 So I'm thinking that I need to add -audit to the /usr/bin/X file, but I believe that it's binary and created by something else, but I can't find that "something else". How on earth can I add this option? I have opened up 1,000,000,000,000,000,000,000 files (slight exaggeration) and I've come up empty.

Does it make sense to run sshd confined/protected by apparmor? I get tons of attack/hack attempts on my ssh port daily, I created a white list on my firewall to specify the IP addresses that can ssh into my network. I was also thinking of activating the sshd profile in apparmor for some added protection?

I have an openSUSE 11.1 and I noticed that after installing a couple of things on it the sshd is not starting anymore on reboot. how can I debug this problem. Is there a log file so that I can see what was the problem? If I want to use ssh I have to start it from yast every time the computer restarts.

Running 11.4 x64, I've tried everything I can think of (which is not saying a lot) but I can't get sshd started on boot. Running /etc/init.d/sshd starts the service manually with no problem but I really need it started on boot.
I can't find anything different when comparing this instance with other similar instances where sshd does start but this instance is an update from 11.3 where sshd was not enabled and the others are all clean installs where sshd was enabled during installation, if that makes any difference.

I had a working setup of opensuse 11.0, dual booting using grub installed on the home partition. I tried to install 11.3 from the coverdisc of linux format (LXFDVD136). It took 5 goes before the install succeeded. Mostly stopping at the "boot installed system" stage. I put 11.3 on a formatted partition in the same place as 11.0, and put grub there too.
The system will not boot without assistance. I have to use a supergrub disc and tell it which partition to boot. If I use boot linux from supergrub I get the Grub error message 15 file not found. Supergrub CAN find windows and it boots with the win command. Automatic and yast initiated attempts to check for software upgrades are blocked by the application with pid 4587.

It's time to bite the bullet before I run out of security update support in December. I also have a sda that is starting to show signs of possibly failing soon when I run smartctl -H. What I want to do is mirror my existing sda with pmagic and upgrade to 11.3. How much trouble will I have going the upgrade route over doing a clean install and trying to import all my Thunderbird/firefox etc data to it with 11.3 and KDE 4.X?

I have followed this article SDB:System upgrade - openSUSE to upgrade from 11.2 to 11.3 using the CLI. After installing I cannot boot into my GUI. I am using an NVIDIA card 7800. It will attempt to got to the log on screen, but will remain in a black scree with just mouse activity. Not sure what the issue is.

I have a VPS with SUSE 11 64-bit installed on it.This as it turns out is 11.1.On looking at the repository it has none listed, so getting updates is kinda hard. I added the 11.1 repository, or what I thought was it, but it tells me it can't update as it needs an x64 installation.I've tried changing the repositories to 11.2, but get the same message, that it needs an x64 installation.I'm aware it's best to upgrade with a fresh install off DVD, but this is something I can't do with a VPS.
1) Is it possible to upgrade to 11.2 or 11.3 from 11.1 .. I know it's not overly advised, but is there a way to do it?
2) What's the actual requirements for these or what repositories should I be pointing to? Because, I'm already on 64-bit, so I don't get why they wouldn't work.
3) Is there any issues with staying on 11.1? And if I do, then what repositories should I be using?

I have been using OpenSuse 10.3 for years. Now decided to upgrade to 11.3 (current latest).My current box connected and configured with so many peripherals and software:
1) DLink wireless router,
2) HP Printer (networked),
3) Cannon scanner through USB,
4) Zoiper VOIP telephony application,
5) etc. etc.
my question is whether it is recommended to upgrade straightforward from 10.3 to 11.3 ? Is there any known issues that I might be encountered after upgrade installation (e.g. loosing any previous data, configuration etc.).
