I haven't tried it myself but maybe it is possible to try on the virtual NICs. The only drawback is that the need to create a way to link the data from the vifs to the corret guest :) Antonio. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Antonio S.

Re: [CentOS] [SOLVED] CentOS-5.4 Update?

I am a digest subscriber and the release announcement is contained in the very digest that contains your message. Therefore the answer is no. My question is: Given the knowledge I possessed, why would I have gone looking for such a document? Is every yum user expected to look for release notes before each and every time that they run yum update? On the other hand, because of yum's apparent inability to clean up after itself, I had previously adopted the practice of running yum clean all before and after every update, which I did do in this case. There is a fundamental problem with the software if an automated package manager like yum requires both prior external knowledge and manual intervention to effect a particular update. Surely if a yum update set contains package dependencies that are sensitive to installation order then there should be an automated means to insure that the requisite packages are installed in the proper order by the package manager itself and not depend on manual intervention. The current arrangement seems to lend itself to unfortunate results. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

Bootable 5.4 USB key...
by John Doe 23 Oct '09

23 Oct '09

Hi, I tried to convert my working 5.3 USB bootable key to 5.4 and I apparently cannot get syslinux to find/read its configuration file anymore... I followed the same process as before: mkfs.vfat -n BOOT /dev/sdg1 syslinux -s /dev/sdg1 cd /media/BOOT cp -rv /mnt/cdrom/isolinux syslinux mv syslinux/isolinux.cfg syslinux/syslinux.cfg rm -f syslinux/isolinux.bin vi syslinux/syslinux.cfg dd if=/usr/lib/syslinux/mbr.bin of=/dev/sdg I get: syslinux: cannot find kernel linux I tried to copy syslinux.cfg in /, but it still fails... Did anyone successfuly create a 5.4 key yet? Thx, JD

Firefox keeps crashing after 5.4 upgrade
by Alan McKay 23 Oct '09

23 Oct '09

I've almost never had crashes before this, and it has been 3 or 4 so far today after my upgrade. Could it be one of my plugins I suppose?

CentOS-5.4 Update?
by James B. Byrne 23 Oct '09

23 Oct '09

hdwr HPQ DC7700S ix86 Core Duo I have just updated this CentOS-5.3 box to 5.4. This process was not satisfactory. While the update packages all downloaded without problem the update process itself stalled at several points. By stalled I mean that at some point the entire process stopped for hours. The packages at which it stalled included evince, evolution, totem and vinfo. There may have been others but these I seem to recall. Restarting the update process required that the existing update be interrupted with a <ctrl>C and yum-complete-transaction run. It took five iterations to get through to completion and in the end I first installed all the remaining packages one at a time directly from the command line using yum install packagename and then ran yum-complete-transaction until all outstanding transactions were cleaned up. Now, while the system boots I have no gnome desktops for any of the users on this host. When root logs in all that is shown is a deep blue background and a wirefram outline of the Firefox web browser, a wire frame outline of an xterm window and an analogue clock. Left clicking on teh background displays a popup menu labeled "Tvm". The mouse and keyboard work and when one clicks on the wireframs then immediately fill with the application background, the CentOS welcome back for FireFox and a black on white scheme for xterm. All the windows have teal menu bars. Further, it seems that I cannot switch between windows. If I try to enter a command in the xterm window then what I type appears in this compose window for squirrelmail. I would like to get my previous customised desktops back, but first I would like to get the default to display. Are there any ideas on how to proceed?

Problems with BCM5709 network
by Toralf Lund 23 Oct '09

23 Oct '09

I've just installed CentOS 5.4 on an IBM server with a BCM5709 network adapter, and can't get networking to work. It looks like an appropriate driver (bnx2) is installed, lspci and the system log return sensible info on the unit, there are no specific error message anywhere, but I get "no link present" when I try to activate the device. In other words, I see essentially the same behaviour as when the network cable is missing, but I've tried several cables, connection points etc. and also get the appropriate indicator lamps etc. so I'm quite sure the connection is good. Does anyone have any idea what may be wrong? If not, have any of you lot got networking to work with a similar setup? Some extracts from the system log are included below...

upgrade to 5.4 openswan broke
by Myron Williams 23 Oct '09

23 Oct '09

Hi All, I upgraded from 5.3 to 5.4 today on a vpn gateway using openswan. After the upgrade the vpn stopped working. From what I could tell the new version of openswan uses NSS. I tried following the instructions in this thead https://bugzilla.redhat.com/show_bug.cgi?id=508107 without success. # certutil -N -d sql:/etc/ipsec.d certutil: function failed: security library: bad database. If I ran the command without the sql: like this # certutil -N -d sql:/etc/ipsec.d it would create the database files. I would then execute # modutil -fips true -dbdir /etc/ipsec.d followed by # /usr/sbin/ipsec newhostkey --configdir /etc/ipsec.d/nssdb --password password1 --output /etc/ipsec.d/host.secrets After replacing the hostkey in the file I tried to bring the connection up but the connection would not start and the following error message was in the log file. unable to locate my private key for RSA Signature sending notification AUTHENTICATION_FAILED I finally had to downgrade from openswan-2.6.21-5.el5 to openswan-2.6.14-1.el5 to get things to work. Am I missing something that is needed to make this work? Any help would be appreciated. Myron Williams
