Default ACL question (EXECUTE BIT)
by Jorge Fábregas 30 Oct '09

30 Oct '09

Hello everyone, I'm doing some tests with ACL's and even though I can create a "default" ACL for a directory (that includes "rwx" for the default owner), when I finally create a file wihin that directory the execute bit is chopped off: [joe@machine ~]$ mkdir mydir [joe@machine ~]$ setfacl -d -m u::rwx,g::-,o::- mydir/ [joe@machine ~]$ cd mydir [joe@machine mydir]$ touch testFile.txt [joe@machine mydir]$ ls -l testFile.txt -rw------- 1 joe joe 0 Oct 29 21:14 testFile.txt I don't think umask is involved here. As far as I know umask isn't involved when dealing with default ACL's. Anyhow, I'm pretty sure this is by design (security-wise). Is there any way to override this behaviour? Thanks, Jorge

RAM errors after kernel-update
by Michael Schumacher 30 Oct '09

30 Oct '09

Hi, I updated a server yesterday from "kernel 2.6.18-128.7.1.el5xen" to "kernel 2.6.18-164.el5xen" After rebooting, my message log is flooded every second or so with this error messages: Oct 6 14:52:20 xenserver1 kernel: EDAC MC0: UE row 0, channel-a= 0 channel-b= 1 labels "-": NON-FATAL recoverable (Branch=0 DRAM-Bank=0 Buffer ID = 0 RDWR=Read RAS=0 CAS=0 NON-FATAL recovera ble Err=0x2000 (FB-DIMM Configuration Write error on first attempt)) and Oct 6 15:17:23 xenserver1 kernel: EDAC MC0: CE row 0, channel 0, label "": Corrected error (Branch=0 DRAM-Bank=0 RDWR=Read RAS=0 CAS=0, CE Err=0x10000 (Correctable Non-Mirrored Demand Data E CC)) The machine is a new Tyan S5397 mobo with 16GB Kingston RAM KVR667D2D4F5K2/8G Removing and replacing memory to different locations doesn't make any difference. After some digging, I noticed that the new kernel has added support for the i5400 chipset. I found some reference that the new kernel has this error reporting capability the old one hadn't. Question1: how many recoverable RAM errors are acceptable? Question2: The error appears always with the same id in the error message. Mobo problem? Question3: Are there any recommended BIOS settings to operate the RAM slower to see if the problem disappears? Question4: Any other proposals. Being located in Germany makes the "just return it to the dealer" proposal quite unattractive. best regards --- Michael Schumacher PAMAS Partikelmess- und Analysesysteme GmbH Dieselstr.10, D-71277 Rutesheim Tel +49-7152-99630 Fax +49-7152-996333 Geschäftsführer: Gerhard Schreck Handelsregister B Stuttgart HRB 252024

resolv.conf rewritten every reboot. How to figure out who and why?
by Dave 30 Oct '09

30 Oct '09

My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient. The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpclient. I'd like to figure out what software is rewriting this file and why. man 5 resolv.conf and man resolver are unhelpful in this case. rpm reports /etc/resolv.conf is not owned by any package. At this point, I am as (or more) interested in pointers regarding how to find the answer as I am in the actual answer. Please teach me to fish. mahalo, Dave

Benefits of VMWare 2.0 over 1.x?
by MHR 30 Oct '09

30 Oct '09

I've been running VMWare Server 1.x for some time now, currently on 1.08, and I've been pretty satisfied with it. I was wondering if any of you fellow VMWare users are seeing any significant benefit to moving to the 2.0 release. I'm running CentOS 5.4 with Linux 2.6.18-164.el5 #1 SMP x86_64 on an AMD 7750 64x2 with 4GB of RAM.... Thanks. mhr

question about mounting external USB HD
by Ivan Arteaga 30 Oct '09

30 Oct '09

Hello, I have a server running CentOS 4.7 and I want to add a new USB-HD for backup some data. I made the file system as ext3 with the command: / mkfs -t ext3 /dev/sdb1/ After that I did add a new Volume Group and Logical Volume (/VolGrup01-LogVol01) /on that file system and mounted it as /backup. It worked fine but when I did reboot the server It wont mount /backup and I got the following error even after the system boots and I try to mount it manually: /mount: special device /dev/VolGrup01/LogVol01 does not exist/ I will appreciate any comment or suggestion about the best way to get through this. Regards, --Ivan.

Upgrading Centos 5.3 -> 5.4
by Rohan Gilchrist 29 Oct '09

29 Oct '09

Still the same problems I'm afraid. I read the release notes and followed them to the letter. I'm now seeing: Finished Dependency Resolution lvm2-2.02.46-8.el5.i386 from base has depsolving problems --> Missing Dependency: device-mapper >= 1.02.32-1 is needed by package lvm2-2.02.46-8.el5.i386 (base) mkinitrd-5.1.19.6-54.i386 from base has depsolving problems --> Missing Dependency: device-mapper-multipath >= 0.4.7-9 is needed by package mkinitrd-5.1.19.6-54.i386 (base) lvm2-2.02.46-8.el5.i386 from base has depsolving problems --> Missing Dependency: device-mapper-event is needed by package lvm2-2.02.46-8.el5.i386 (base) Error: Missing Dependency: device-mapper-multipath >= 0.4.7-9 is needed by package mkinitrd-5.1.19.6-54.i386 (base) Error: Missing Dependency: device-mapper-event is needed by package lvm2-2.02.46-8.el5.i386 (base) Error: Missing Dependency: device-mapper >= 1.02.32-1 is needed by package lvm2-2.02.46-8.el5.i386 (base) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest I've installed package cleanup and tried the suggested combinations, except the --skip-broken option. Any thoughts are appreciated. Rohan.

printers... (HP)
by m.roth＠5-cent.us 29 Oct '09

29 Oct '09

I can't remember if I asked here - I've got more than one printer, HP, laser, builtin JetDirect. When I go there in a browser, I see the basic thing, but I can't get to the networking page. It says that it wants a password, no user name. It doesn't accept anything. Last week, a co-worker reset one to factory defaults... and it comes up with the same thing. Looking around on the Web, I don't see anything about a default password. Clues for the poor? mark

Not able to FTP since 5.4
by Bob Hoffman 29 Oct '09

29 Oct '09

I do not use ftp much lately, but my bro did and noticed we cannot ftp to the server since the upgrade. Using VSFTP. Tried rebooting but nothing. Looks like it goes through the whole process and then 'bam'. Could not find an error log that listed the error anywhere. Worked great before 5.4 update, now it does not work at all. Here is the info from cuteftp. STATUS:> Getting listing "/"... STATUS:> Connecting to FTP server 72.35.68.61:21 (ip = 72.35.68.61)... STATUS:> Socket connected. Waiting for welcome message... 220 Welcome to the server STATUS:> Connected. Authenticating... COMMAND:> USER xxxxxxxx 331 Please specify the password. COMMAND:> PASS ***** 230 Login successful. STATUS:> Login successful. COMMAND:> PWD ERROR:> Can't read from control socket. Socket error = #10054. Any ideas? Thanks. Bob
