CentOS 5 Networking :: GDM Or PAM Broken After Upgrade 5.4 To 5.5?
May 20, 2010
I have a number of CentOS 5.4 machines that use kerberos to authenticate. This works fine. However, after upgrading one of them to CentOS 5.5 it is no longer possible to log in.
In 5.4, I get this in the log:
> called to authenticate 'hans', realm 'MYREALM'
> authenticating 'hans@MYREALM'
> not using an entered password for 'hans', allowing libkrb5 to prompt for more
> authenticating 'hans@MYREALM' to 'krbtgt/MYREALM@MYREALM'
[code]....
Note the absence of the line where libkrb5 asks for a password. Running "kinit hans" on the machine (as root, who can log in) works as it should, so I don't think anything is wrong with kerberos as such (as I did yesterday, in [URL]. Clients still running 5.4 have no problems, so the problem was introduced in 5.5.

I had a working client installation with CentOS 5.4, using kerberos and PAM to authenticate. After an upgrade to 5.5, logins for users are no longer possible. Instead I get this:
/var/log/messages: gdm: Couldn't set acct. mgmt for <user> /var/log/secure: gdm: pam_krb5: authentication fails for '<user>': (<user@domain>): Authentication failure (Cannot read password) gdm: pam_krb5: account checks fail for '<user>': unknown reason -1765328254 (Cannot read password) gdm: pam:krb5: User not known to the underlying authentication module (Client not found in Kerberos database) "kinit <user>" still works as expected, and <user> has no problems logging in from other types of clients. Something kerberos-related apparently broke in CentOS 5.5,

After upgrading to CentOS 5.3 my sendmail will no longer deliver messages using a program in my /etc/smrsh. It fails with the message "unknown mailer error 1". This program was working perfectly before I did the upgrade using yum. Here is the list of packages that were upgraded. Does anything jump out as being the source of the issue? I don't believe that sendmail itself was upgraded:
Packages Installed:
dbus-libs - 1.1.2-12.el5.x86_64
libselinux-utils - 1.33.4-5.1.el5.x86_64
Packages Updated:
initscripts - 8.45.25-1.el5.centos.x86_64

I need to downgrade glibc due to a broken kernel after a libc6 upgrade attempt. See:[URL]..Especially with the reduced capabilities I have right now (few if any programs are working), how might I go about downgrading glibc to 2.6?

I recently upgraded my x86_64 system from FC8-FC10 using Pre-Upgrade, and here I got some help fixing all the package conflicts that resulted. Following the first reboot after this massive package update, it appears DNS doesn't work in some apps.
I could ping www.yahoo.com, and nslookup www.yahoo.com resolved the name, but firefox and links couldn't. Typing the ip addr that nslookup gives for www.yahoo.com works fine in both firefox and links. Something's obviously wrong with DNS.
I found a workaround for Firefox which is to browse to about:config and set network.dns.disableipv6 = true. Firefox started resolving names after that.
But then I noticed yum is DNS incapable as well. I don't know how to fix it. Here's what I get:
Code:
[~]$ sudo yum update
Loaded plugins: allowdowngrade, refresh-packagekit
http://linuxdownload.adobe.com/linux/i386/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Trying other mirror.
[Code]....
Does anyone have any additional info on workarounds or fixes for this DNS problem?
The machine in question has a static ip addr, and I have static nameserver addrs in /etc/resolv.conf, corresponding to the static settings provided by my isp.

I have a thinkpad using the iwl3945 driver (Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks).
This worked flawless until I upgraded to 10.04. Now after a while my connection drops. Syslog is appended.
May 10 20:16:04 gimli NetworkManager: <info> Activation (wlan0) starting connection 'Auto my-network'
May 10 20:16:04 gimli NetworkManager: <info> (wlan0): device state change: 3 -> 4 (reason 0)

I recently upgraded Ubuntu 9.10 to 10.04 and my wireless stopped working. It can detect that there are networks around, what their signal strength is, and then try to connect to one, but it just keeps connecting. After around 5 minutes, this stops and nm-applet says no network connection.
After I try to connect, dmesg is spammed with hundreds of the same message. I can not post these here, as I am writing from a different computer and I have no internet access from my main computer.Also, there is nothing in interfaces.conf other than lo. For some reason, my card is referred to as both wlan0 and wmaster0, with this changing depending upon where I look.Most interesting of all is that, even after I reinstalled 9.10, wireless is still broken, even though it wasn't before. It also used to work under liveCD.

I am currently working to get to a stable dual boot Win7/CentOS 5.5 configuration on a Dell Latitude E6510 with the Intel 82577LM chipset. I haven't gotten the Centrino N WiFI chipset working yet, but the Eth0 device was working just fine.However, yesterday I did a system update. I did not pay close attention, but I believe the update did mention networking, because I thought it might help me get my wireless going. Now, Eth0 fails with the message, "Determining IP information for eth0... failed; no link present. Check cable?" It does this at boot up and if we try reactivating it once the system is up. We have tried unstalling and re-installing the driver.The Window 7 boot sees the adapter and runs just fine. I was at a different site location yesterday when everything was working, but my co-workers and I can't help but think it might be related to the update yesterday, since everything worked prior to the update and Windoze 7 works fine with the adapter.
I have not been able to mount my NTFS harddrive on the CentOS side, despite installing fuse, and I don't have wireless, which makes it difficult to get access to new drivers. I also have a FAT32 partition that would be great to share between the boots for passing info, but I haven't found a way to mount a FAT32 partition in CentOS.

I was having a problem with a fresh 11.04 install and the VPN software I use for work. I found the fix was to upgrade the software, so I downloaded an RPM, converted it to .deb and installed it via dpkg. The install worked and the VPN software now works, but Package Manager says I have a broken package and wants to 'upgrade' to the older broken one. How can I fix this without breaking my VPN SW again?

I am running CentOS 5.3.The NIC on my motherboard does not support gigabit, so I bought a gigabit network card. I installed the network card and configured it via system-config-network. Everything seems to work fine as long as I keep a cable plugged into the original NIC. The original NIC works just fine if it is the only one with a network connection, but as soon as I uplug the original NIC I can no longer ping nor connect to the server via the gigabit NIC.
The original NIC is eth0, the new NIC is eth1. Is there something I need to do to tell the system that eth0 is not required or something? I've never encountered an issue like this before...

After upgrading my 64bit 9.10 install to lucid, KDE went poof. I am presented with the login screen, and after supplying my credentials the screen goes black and all I am left with is a mouse pointer.
According to ps kded4 is dead (zombie). kdm.log also indicates a problem with ibus. I installed the "ibus" pkg, but didn't resolve it. Attached is an excerpt of my kdm.log, I can't really find useful information in syslog/dmesg/messages. The system is up-to-date and I've tried starting with a clean user account as well as removing the .kde directory.

Curious thing happening since upgrade. The desktop toolbar is invisible, although I can get click and access the drop down menus for login, calander, power settings etc. Alt-tab works in 2D. The new desktop icons for natty are also invisible. I have tied to access a terminal using Alt-F2, but terminal window doesnt open. I had compiz running on previous 10.10 installation. I am at a loss as to where to begin fixing this. If I didn't have a windows 7 installation partition that would get screwed up I would flatten the installation and download and install a fresh install, but I do and I don't want to go through that pain if I don't have to.
Running Lenovo 3000 C200 with intel gm1345 gfx.

I have just upgraded a CentOS 5.2 box to Centos 5.3
I did have a bridged networking setup for Virtualbox which worked well. eth0 was bridged with br0. br0 boot protocol was DHCP and it sent its DHCP_HOSTNAME to the windows DHCP servers.
since the upgrade the br0 does not get an address but the eth0 does. I found that the scripts in /etc/sysconfig/network-scripts/ifcfg-* are getting rewritten.
I figure I may not need to have a bridge any more so I stripped that out to try to get a simple network setup working. I now just have eth0. I edited /etc/sysconfig/network-scripts/ifcfg-eth0 so that it looked like this,
~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Attansic Technology Corp. L1 Gigabit Ethernet Adapter
DEVICE=eth0
BOOTPROTO=dhcp

After I did a safe-upgrade on my lenny system, clamav is now broken, which is quite a pain since my e-mail flow is now failing.
I get this in the log. CLAMAV: couldn't connect to: /var/run/clamav/clamd.ctl:
I have volatile in the list, and clamav is also installed from volatiel of what I can see, so what went wrong? Is the package broken?

I was trying to clean up packages after an upgrade and I broke yum.
Quote:
There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
Please install a package which provides this module, or verify that the module is installed correctly.
It's possible that the above module doesn't match the current version of Python, which is:

Like so many others, after upgrading 8.04->10.04 LTS, Bluetooth is now busted. I've spent the better part of a day trying to find answers; I've tried many things and the results have not been consistent. I'm not going to write a book here as there are many other posts on the same problem and no real answers other than to complete a fresh install. I CAN do that but I'll have to overcome one bothersome problem:
Bluetooth is an important protocol. Now my (Bluetooth) broadband adapter is busted and I have to try and resolve this issue using a lousy phone line and modem. Needless to say... I can't download a new distro with that configuration. The updates would take weeks!
I suppose I'll have to drive into town and get someone to burn me a copy of 10.04 lts... Hope that works!
I'll think twice (or more) before upgrading an LTS distro again! That machine was working great....I don't know why I upgraded.. security concerns mainly. live and learn I guess... live and learn.

11.04 has finally fixed my Screen Resolution problems. Yippee. But now the Internet access has broken, again rendering my Ubuntu installation mostly useless. Yes, it tells me Wired internet disconnected, after repeated attempts to gain access to the internet over a LAN cable. I have tried everything to get it to work, even manually entering all the info to allow access to my router. But still No. What is even more frustrating is that the internet worked fine on the Live CD, but not on the final installation.

I was updating from 10.04 to 10.10 (was updating through update manager) after some time I got following message:
Code:
An unresolvable problem occurred while calculating the upgrade:
E:Unable to correct problems, you have held broken packages.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report. When I tried to run the command
Code:
ubuntu-bug update-manager
as above message says I got error

I upgraded my server yesterday via apt-get and my Perl scripts are not able to make HTTPS connections due to certificate verification problems.
This seems to be a problem for EVERY HTTPS site.
CURL gives the following error:
Code: Select allSSL certificate problem: unable to get local issuer certificate
I know that this has something to do with root certificate updates, but if I sound ignorant about it, it's because I am.
using CURL with the -k option allows the connection to be made.
I'm running OpenSSl 1.0.1k-3+deb8u2 on Jessie 8.2.
I would obviously prefer to not disable certificate verification on my server.

I would like to ask whether somebody has had the similar experience after KDE 4.4 upgrade.
1. From the attached picture you can see that an icon for xine has a different size. When I change it manually and align the icon, it has previous status after the restart. If I delete that icon and recreate it again, it's smaller than other icons. Icon size for desktop is set up to 32, Desktop Activity.
2. Minimizing/maximizing e.g. Firefox breaks all icons in task bar. I am able to refresh only Firefox/Thunderbird icons.
What can cause these issues? Maybe:
1. my nouveau driver
2. bugs in KDE 4.4.
3. my theme

I recently upgraded to Fedora 14 from F13 using Yum, it worked to my amazement except now yum appears to be broken because of a massive amount of dependency issues. It appears the old F13 packages are still around and yum is unable to get ride of them because their dependency with F14 packages of the same name. I tried yum distro-sync, and I tried yum resolvedep $(package-cleanup --orphans) --skip-broken but to no avail. Package--cleanup--orphans identifies all of the left over F13 packages.
I also can't install or upgrade anything using Yum, does give me a reason except the massive amount of dependency issues with the left over F13 packages. When I use the graphical software update it tells me among other things that Yum and RPM have updates but of course it won't update. I did follow the instructions and used yum update yum before I upgraded to F14, maybe it didn't take? Anyway to resolve this issue other than a clean install?

I have an Epson Stylus Photo PX710W. It worked fine in opensuse 11.2, but I've now done a fresh install of opensuse 11.3 and I can't get the printer to work. I set it up as for 11.2, so I'm sure it should just work.
CUPS job page says:
stopped
"/opt/epson-inkjet-printer-escpr/cups/lib/filter/epson-escpr-wrapper failed"
and CUPS error log says:
PID 1294 (/opt/epson-inkjet-printer-escpr/cups/lib/filter/epson-escpr-wrapper) stopped with status 127!
While the scanner also isn't working, I think this is a separate issue as the CUPS log seems to suggest it is connecting to the printer, + I'm using network and usb connection.
