curlftpfs
by James B. Byrne 12 Jul '11

12 Jul '11

CentOS-5.6 fuse-2.7.4-8.el5 fuse-curlftpfs-0.9.1-1.el5.rf I am trying to mount an ftp connection as a local file system using fuse and curlftpfs. I can connect to the remote system (an HP3000 running MPEiX 7.5) and the directory seems to mount but I cannot use it. What I get is an Input/output error: $ curlftpfs -v hahp3k01.harte-lyne.ca tmp/hp3000 * About to connect() to hahp3k01.harte-lyne.ca port 21 * Trying 192.168.1.102... * connected * Connected to hahp3k01.harte-lyne.ca (192.168.1.102) port 21 < 220 HP ARPA FTP Server [A0012H15] (C) Hewlett-Packard Co. 2000 [PASV SUPPORT] > USER FTPUSER.HARTLYNE < 331 Password required for FTPUSER.HARTLYNE.

Suggestions as to what is wrong and how I can get this to work are most welcome. -- *** E-Mail is NOT a SECURE channel *** James B.

Re: [CentOS] Installing from CD
by david 12 Jul '11

12 Jul '11

Dear Gurus Thanks for the responses. I'll summarize what I've learned trying to install Centos6 on a Dell Optiplex GX 240 Review: a) I decried the lack of CD images for Centos6. b) I was informed that it's unlikely they'll be produced due to an upstream decision. c) I pointed out that the machine only had floppy, CD and HD boots capability. d) I got a suggestion to use the network method. Results: 1) PXE boot might work, but it seems that it's a lot of trouble setting up a PXE server. I'm still working on it. 2) The NET-INSTALL indeed did work, with the following gotchas: 2a) The URL to enter is not obvious. 2b) I tried the one at Stanford, and at uidaho, but they failed. 2c) Finally, http://mirror.centos.org/centos/6.0/os/i386 worked. 3) SInce I had only a text install, various interesting and important programs were missing: ssh (which apparently is masquerading under the name "openssh-clients"), ftp and perl, which YUM got for me. 4) The module perl-Digest-MD5 was not in the repository. Was its removal intentional, or is it hiding in some other Centos6 repository? 5) The line-by-line notation during bootstrap is no longer shown. This makes it difficult to detect where hangups occur during the bootstrap process. Is there a way to display those notations in real time? Conclusion: I'm still trying David

Clearlooks & Bluecurve icons missing from Centos 6
by Frank Cox 12 Jul '11

12 Jul '11

The Clearlooks and Bluecurve icon directories that were provided under Centos 5 that have disappeared on Centos 6. Clearlooks icons were provided by gnome-themes-2.16.0-1.fc6 and has disappeared with gnome-themes-2.28.1-6.el6.noarch, and Bluecurve icons were provided by redhat-artwork-5.1.0-28.el5.centos, which doesn't appear to exist at all with Centos 6. Were these icons removed for a reason? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com www.creekfm.com - FIFTY THOUSAND WATTS of POW WOW POWER!

Re: [CentOS] Triggering script from cron or web client

Web page creates a temp file saying "update", then cron job runs once a minute looking for that file, kicks off update script, then deletes temp file. If you don't want to wait a full minute you could use 'incron' to monitor the temp directory and kick the update right away. Seems better than having something in a loop constantly checking. -☙ Brian Mathis ❧-

Hard disk installation
by Timothy Murphy 11 Jul '11

11 Jul '11

Has anyone installed CentOS-6 from the hard disk? I just tried this without success. I should say that I asked the question before about CentOS-5.6, and while I got many suggestions in reply, no-one actually said that they _had_ installed CentOS this way. What I did was to "mount -o loop" the DVD iso (which I checksum-ed) and copy isolinux/vmlinuz and isolinux/initrd.img , as well as the images/ directory, to /boot , and then added a simple stanza ------------------------ title CentOS-6 root (hd0,1) kernel /vmlinuz text askmethod initrd /initrd.img ------------------------ The machine - I should have said that it is an HP MicroServer - boots fine, until it gets to "Waiting for hardware to initialize", at which point the screen goes blank and nothing appears to happen. I should say that the machine is running under CentOS-5.6, which I installed with a USB stick. I'm trying to install CentOS-6 on another partition. I shall try the USB stick method shortly. But I would be interested to know if anyone has actually installed CentOS-6 from the hard disk, and if so how. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Updates... What? already?
by Mark Weaver 11 Jul '11

11 Jul '11

Just had a good laugh. I'm sitting here at my desk working with my laptop sitting off to the side; I've just loaded C6 this morning and as I understand it C6 _just_ finished syncing on the mirrors over the weekend. I look up from an email I'm composing to see the updates alert being displayed. I won't repeat what first entered my head, but I couldn't help but laugh and think, "How the hell can there be updates already for an OS that just got released?" -- Mark Weaver Computer Information Systems & Services, Inc. mweaver(a)compinfosystems.com (717) 512-9718

No Package Manager? (Where's YumEx)
by Mark Weaver 11 Jul '11

11 Jul '11

Hi List, This morning while setting up C6 on my laptop this morning I attempted to download and install Yumex, but the repos returned no results for this package. Has this been discontinued and if so, what package manager should I be looking for? thanks, Mark

Deleting a KVM virtual machine from the command line
by Sean Carolan 11 Jul '11

11 Jul '11

I am working on a sandbox machine that will allow users to play around with building virtual machines, then blow them all away each night with a cron job. I wrote a small script that uses the virsh command to destroy the VMs, then remove the storage. For some reason the vm name still shows up in the virt-manager GUI. Anyone have an idea how you delete it from there as well, without using the GUI? thanks Sean

CentOS 6 and pxeboot
by m.roth＠5-cent.us 11 Jul '11

11 Jul '11

Well, I started the install, got pxeboot to get to the kickstart file, formatted the drive... and then it failed, telling me "unable to read group information from repositories. This is a problem with the generation of your install tree." A quick google gives me the first hit from a year ago, bug 4372 <http://bugs.centos.org/view.php?id=4372>, which says there's a metadata problem. Has anyone else run into this today? mark
