RE: [CentOS] grep

Or, in extreme cases, I'll write a small utility script. Or, more commonly, I'll write a huge inline Perl monstrosity that really should have been done as a utility script. (It's really hard to sort out nested loops and conditionals without any formatting...) -- Bowie

CentOS 4.5: Automounted USB disks eventually stop appearing on desktop
by Bart Schaefer 28 Aug '07

28 Aug '07

This is just a minor annoyance, but I wondered if anyone has any insights. When I first boot the system and log in to Gnome, and then plug in e.g. a USB stick or compact flash card, I get an icon for it on the desktop. I can right-click on this icon to "eject" the filesystem, etc. Eventually, though, for no obvious reason, this stops working and I no longer get an icon when I insert a USB device. The automount is still happening; I can still navigate to the device under /media with Nautilus, and I can still umount it from a shell as a nonprivileged user. What process is supposed to be noticing the new mount and adding the icon? Any clues as to why it would stop doing so?

Can't print from Firefox
by Niki Kovacs 28 Aug '07

28 Aug '07

Hi, I've just installed CentOS 5.0 on my father's laptop, in replacement of Windows XP. Everything runs fine, except I can't seem to print from Firefox. So far, I can print a test page from the CUPS interface (as root). As user, printing works fine from applications such as GEdit or OpenOffice.org Writer. But I can't print anything from Firefox. Any suggestions? Niki Kovacs

CentOS/RH 5 Samba as PDC+NIS w/o LDAP?
by Scott Ehrlich 28 Aug '07

28 Aug '07

For those who are new or forget - I have a RHEL 5 Server and a few dualboot XP w/SP2 and CentOS 5 systems. The Linux machines were installed straight of CD/DVD, no patches. I was initially going to try a single sign-on to the RH 5 box via LDAP, but RH says it simply isn't possible and I don't know my way around LDAP other than it is a database and exists. So, option 2 is to simply have the RH 5 Server act as a Windows PDC via Samba and use NIS to enable users to log in, all the while, in either situation, having the RH 5 box serve out the user's central home directory - mounted as a drive letter under Windows, or exported under Linux. I've spent much of last week and much of today [trying to learn] LDAP, and today, finally deciding to dump that, but proceeding with Samba as a PDC. For Samba as a PDC - what is the best way to have Win XP Pro w/SP2 successfully authenticate to Samba as a domain controller with encyrpted passwords? And, to have Samba establish the user's home directory as a mapped drive? I've used a barrage of web sites showing various smb.conf confing files but can't yet get my test XP machine to authenticate to the domain I set in my smb.conf file. For NIS - what is the best way to permit the user to log into their account, created on RH 5 server, and have their home directory exported to their workstation? I presume there will be no problem with users simultaneously logging into multiple workstations, be it Linux or Windows? I only bother the list because I have scoured so many web sites, some with a variety of options, I believe I'll get the best answer here. Thanks. Scott

Creating your own CA and SSL certificates
by Brian Mathis 28 Aug '07

28 Aug '07

I've been looking all over (google, wiki, manuals) for docs, and I can't find any mention of how to set up a CA or certificates *specifically for centos 5 / upstream 5*. There are plenty of generic guides on using openssl for this sort of thing, but I'd like to play nice within the standard structure of this system. I've found the /etc/pki directory, but can't find much information about it. I reviewed the openssl.cnf file, and it looks like it's not completely set up, as many directories it references do not exist on the system. What I'm looking to do is set up my own CA, then make some certificates for use with SSL, and sign them with the CA. This will be used for internal purposes. Any pointers to guides or information would be appreciated. Thanks.

Strange behavior from OO Writer
by Mark Hull-Richter 28 Aug '07

28 Aug '07

I just had the strangest experience I can remember since I ran Windowsas my base OS.... Yesterday I was editing a file in the OO Writer (word processor). Today, it will not open. I copied it to a new file, and it opened fine. I edited it, updated it and closed it. Then I tried deleting the original file and copying the new one to the old name. Won't open. Renamed again, and it opens fine. WTF???? Does OO and/or the writer have name prejudices that develop? Thanks. mhr

Xen VM vanishes after creation
by Kai Schaetzl 27 Aug '07

27 Aug '07

Just starting and playing around with Xen on Centos 5. I created a new VM (para-virtualized) with the Virtual Machine Manager, installed Centos 5 minimal on it, rebooted after successful installation. The VM console vanishes on shutdown and that's it. The VM id vanishes from the VM Manager and there's no way to get it back. It looks like the new VM doesn't exist. xm list shows only Domain-0, virsh list --all tells me that it cannot list the inactive domains. A restore from the VM file fails as well. The VM image file exists (in /home/vm), a config file for it in /etc/xen exists. But I don't see where the path to the image file might have been saved. Maybe that's the problem? (I know the location can create a problem with SELinux, but I'm currently running permissive and only testing.)
