2.6.18-92.1.6.el5xen hangs Samba daemon
by Brett Serkez 01 Jul '08

01 Jul '08

All, I have a fresh CentOS 5.2 server that I am just starting to customize, it is very close to stock. This morning I ran yum update: ============================================================================= Installing: kernel-xen i686 2.6.18-92.1.6.el5 updates 15 M Updating: samba i386 3.0.28-1.el5_2.1 updates 16 M samba-client i386 3.0.28-1.el5_2.1 updates 4.9 M samba-common i386 3.0.28-1.el5_2.1 updates 8.7 M After rebooting, Samba would not start, running 'service smb start' simply hangs forever, nothing in the logs I could find and I could see from ps that smbd was never forking to release the start script. I discovered that if I boot using the previous kernel 2.6.18-92.1.1.el5xen all is well. I did try regressing samba by uninstalling and then installing disabling the updates repo to no avail, the older version (1.1) of Samba was installed when I tried booting the older kernel, which did work, as well as the updated version (1.6).

self Certificate Authority, using /etc/pki/tls/misc/CA
by David Hláčik 01 Jul '08

01 Jul '08

Hello all, lately i am facing problems with Certification Authorities. I have used centos script /etc/pki/tls/misc/CA my own certificate authority. In next steps i am generating requests for certificates to services such as LDAP,NNRPD and lately signing requests with CA. My approach is to import my own CA into Windows Vista OS as root CA and trusted, to avoid messages in clients such as "certificate could not be verified, certificate is not signed or cerficate authority cannot be verified". When i asked for help at openssl mailinglist i have recieved interesting answer : Just make sure your certificate is actually one "son" of your CA. > > It is right To make one CA cert with the 509 extensions set to CA > X509v3 Basic Constraints: > CA:TRUE > X509v3 Key Usage: > Certificate Sign, CRL Sign > Netscape Cert Type: > SSL CA, S/MIME CA > > But it is a mistake to make the "son" as ANOTHER SELF SIGNED cert with > those > extensions not set as CA > X509v3 extensions: > X509v3 Basic Constraints: > CA:FALSE > Netscape Cert Type: > SSL Client, SSL Server, S/MIME, Object Signing > X509v3 Key Usage: > Digital Signature, Non Repudiation, Key Encipherment > Netscape Comment: > > I know of important companies doing this mistake. > The second cert has to be one SIGNED by the first CA authority, not a > selfsigned one with CA fields "off" of false. > Said in other words: the second cert is the result or output of a CSR > (certificate signing request) signed by the CA cert. Yes, that is true, so why this is not so in case of /etc/pki/tls/misc/CA . All my generated server certificates signed with own CA, using this script have : X509v3 extensions: > X509v3 Basic Constraints: > CA:FALSE > Netscape Comment: > OpenSSL Generated Certificate > X509v3 Subject Key Identifier: > CC:FC:A1:2D:DE:CD:D1:9E:34:F3:89:08:F9:D6:30:79:AF:EE:6B:94 > X509v3 Authority Key Identifier: > > keyid:C7:B9:B0:BC:5A:A2:73:18:02:F2:80:E2:8A:0C:BC:58:0C:87:14:95 Thanks in advance!

where is ProxyHTMLURLMap for C5 ?
by tblader 01 Jul '08

01 Jul '08

Hello, I'm setting up a reverse proxy in Apache (httpd-2.2.3-11.el5_1.centos.3) I have some pages being served which contain hard-coded names of machines behind the proxy, which obviously do not resolve on the client side. I found an Apache config item called ProxyHTMLURLMap* which supposedly will allow me to re-write these hostnames, but can't seem to find the apache module to install Starting httpd: 'ProxyHTMLURLMap', perhaps misspelled or defined by a module not included in the server configuration Anyone know what the name of that rpm/module is for Centos 5? Thanks!

Lost mail
by Anne Wilson 01 Jul '08

01 Jul '08

I did an update yesterday evening, and didn't spot that it had changed permissions on my .procmailrc. Consequently no mail came in after that. I've been out most of today, so just got it fixed, but what will have happened to the mail for the missing period? Maillog just shows that messages have been passed to procmail. Procmail won't run if the perms are wrong, so where do the messages go? Anne

[CentOS4.6]Where can I get these packages (xorg-server xproto fontsproto)?
by huo jinzhe 01 Jul '08

01 Jul '08

When I install xf86-video-intel-2.3.2, Package requirements were not met. And " yum list | grep xorg-server " can not find such package. Where can I get these packages (xorg-server xproto fontsproto)? Thanks in advance. The log information is below: ./configure ...... checking pkg-config is at least version 0.9.0... yes checking for XORG... Package xorg-server was not found in the pkg-config search path. Perhaps you should add the directory containing `xorg-server.pc' to the PKG_CONFIG_PATH environment variable No package 'xorg-server' found configure: error: Package requirements (xorg-server xproto fontsproto ) were not met: Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables XORG_CFLAGS and XORG_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

by hce 01 Jul '08

Hi, I tried to install lighttpd in CentOS 5.2, but yum list lighttpd returned an error of "no matching packages to list". Should it be installed from source tarball? Thank you. Kind Regards, Jim

nfs cannot see mount points on other machine
by Kai Schaetzl 01 Jul '08

01 Jul '08

I'm having a bit of a problem with what I can "see" over nfs. I have two machines that nfs their root to each other and it seems to work. However, I now found out that some of the root directories that are listed are "fake" ones. A comparison of the root on both machines shows that some directories are the same and I can access those files on the other machine. However, there are some directories that are different. That is true for all the "special" directories like dev, proc, sys (which makes some sense), but also for directories that are mount points on the other machine. Does nfs not give me access to those mount points? Do I have to create a second nfs mount to that machine which mounts only that mount point? Or do I need some parameter to mount these mount points under the normal mount? What's weird is that if I create a file in these "fake" directories I can do that and it's listed like it actually were created on the other machine. But it gets created on *this* machine. When I then unmount, it's gone (like the whole nfs mount) and when I remount it's back. Where is it actually getting created and how can I remove it? Is there some nfs cache that holds it?

Pidgin problem on 5.2
by fred smith 01 Jul '08

01 Jul '08

Having a problem with Pidgin that may have come after the 5.2 upgrade. I don't use pidgin daily, but the last time I used it (a week or two ago) it was fine. Now, when clicking the icon nothing visible happens. When I open an xterm and run it from there I get this: $ pidgin libnm_glib_nm_state_cb: dbus returned an error. (org.freedesktop.DBus.Error.ServiceUnknown) The name org.freedesktop.NetworkManager was not provided by any .service files and the terminal does not return to a prompt. there is no visible window for Pidgin, but parts of it may be running, as I heard the sound that (I think) means "buddy comes online". running "ps ax | grep -y pidgin" returns one process, so it's not entirely kaput. Anyone else seem this, or anyone have suggestions? Oh, also, I've recently enabled "desktop effects". I think I'll disable that and see if it helps. -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- I can do all things through Christ who strengthens me. ------------------------------ Philippians 4:13 -------------------------------
