CentOS6 and tilde expansion
by isdtor 05 Jan '12

05 Jan '12

Set up NIS and autofs on this new CentOS6 box, but it seems tilde expansion no longer works in bash? [root@frodo ~]# cd ~john -bash: cd: ~john: No such file or directory [root@frodo ~]# cd /home/john [root@frodo john]# pwd /home/john [root@frodo john]# It still works in t/csh: [root@frodo ~]# /bin/csh [root@frodo ~]# cd ~john [root@frodo ~john]# pwd /home/john [root@frodo ~john]# I couldn't find anything in the bash man page that suggests this feature needs explicit configuration.

A simplistic parental-control setup
by Marko Vojinovic 05 Jan '12

05 Jan '12

I am looking at the simplest (implementation-wise) solution to the following problem (on CentOS 6.2): I have a list of web addresses (like http://www.example.com, https://1.2.3.4/, etc.) that should be "forbidden" to access from a particular host. On access attempt, the browser should be redirected to a local web page (file on the hard disk) with the explanation that those addresses are forbidden. The possible ways of disallowed access include: * typing www.example.com or http://1.2.3.4/ in the browser * typing www.example.com/anyfolder/somefile.html in the browser * clicking on www.example.com when listed as a link on some other web site (say, Google search results) * nothing else. The last point above assumes that the users will never try any other method of accessing the site. These user's knowledge about computers in general is known to be elementary, so I don't need protection against geniouses who can figure out some obscure way to circumvent the lockdown (and please don't tell me that this is an irrational assumption, I know it is...). If possible, all this should be on a "per user" basis, but if implementing it system-wide would be much simpler, I could live with it. :-) The point is that I need a simple, easy-to-implement, easy-to-configure and easy-to-maintain solution for this particular usecase. What I don't need is some over-engineered solution that covers my usecase along with a whole bunch of stuff I will never need, and takes two months to configure properly. It should also be F/OSS, preferably included in CentOS repos or elsewhere. Or alternatively I could go along with manually setting up a bogus httpd/dns/iptables configuration which would do all this, but I have a feeling that it would not be the easiest thing to maintain... I'd appreciate any suggestions. :-) Best, :-) Marko

dhcp lease-time
by Timothy Murphy 05 Jan '12

05 Jan '12

Why is the default lease-time set to only 10 minutes (600 seconds) in /etc/dhcp/dhcpd.conf (CentOS-6.2) as distributed? Why is not set to a much longer time? Is there any disadvantage in doing that? Or conversely, is a short lease-time safer in some way? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

Cannot use kickstart file to install CentOS 6.2 into a blank harddisk
by lee_yiu_chung＠yahoo.com 05 Jan '12

05 Jan '12

I am trying using a kickstart file to install CentOS 6.2 into a new virtual machine (the MBR sector of the harddisk is all zero), however I found that the installer cannot go through the harddisk partition. It failed after I chose "Use All Space" at harddisk partition option. The error message is: http://anony.ws/i/bMcTJ.png "You have not defined a root partition (/), which is required for installation of CentOS to continue. You have not created a/boot/efi partition (note: I am using BIOS, not (U)EFI) This can happen if there is not enough space on your harddrive(s) for installation." However, if I create a blank MBR partition table before before CentOS installation, then there is no problem. The same kickstart file works for CentOS 6.1 with blank harddisk. (with url parameter changed of course) Below is the kickstart file I used (between dash lines) ------- url --url="http://ftp.twaren.net/Linux/CentOS/6.2/os/i386/" interactive timezone Asia/Hong_Kong firstboot --enable ------- Steps to reproduce: 1. create a new virtual machine with blank harddisk image (or, a real blank harddisk) 2. boot the netinstall iso 3. at boot menu, press tab and append ks=<kickstart_file_location> and press enter to boot 4. go through the boot option as usual until harddisk partition options 5. Choose "Use All Space" at harddisk partition options 6. error occurs

fail2ban won't die
by Timothy Murphy 05 Jan '12

05 Jan '12

If I lose my broadband connection here (Italy), and try to re-boot the computer (CentOS-6.2), the shutdown hangs at fail2ban. Normally there is no problem re-booting; it only happens if the network has gone down. It may just be an extraordinarily long timeout. Has anyone experienced this? And is there anything one can do about it? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

ASP running on a Linux Machine
by Jonathan Vomacka 05 Jan '12

05 Jan '12

Good morning all, I currently have a website that was written in ASP back in 1999. The system is currently running Windows 2003 Server with MsSQL. Before everyone flames me for being in the wrong place, I was wondering if there is a way to allow centos to run old ASP code? I know years ago this wasn't possible without a program like ChiliASP, but noow I heard rumor that apache might have a plugin to allow it to read ASP. I am unsure if there is an apache solution, or other solution like nginx/lighttpd that runs ASP. Any information you guys could provide would be great. I do appreciate your help in advance PS. I will need to convert the mssql data to mysql, is there any good program that will convert this? I understand that this question is probably inappropriate for this e-mail thread but maybe someone could shoot me a quick suggestion.

server host keys for kvm clones
by James B. Byrne 04 Jan '12

Respecting cloning vm guests, I see in /etc/ssh the following: ssh_host_dsa_key ssh_host_dsa_key.pub ssh_host_key ssh_host_key.pub ssh_host_rsa_key ssh_host_rsa_key.pub Is there a simple script somewhere to regenerate all the server host keys for the new guest after cloning? -- *** E-Mail is NOT a SECURE channel *** James B.

PHP 5 bug?
by Lists 04 Jan '12

04 Jan '12

I'm using EL6 with all updates applied and getting bit by a PHP5 bug that was fixed a year and a half ago... https://bugs.php.net/bug.php?id=52534 EL6 ships with php 5.3.3, which was released prior to the bug fix. What are the chances that this fixed bug can be reported/fixed upstream at the prominent North American Linux Vendor? Here's sample code that demonstrates the problem: function CheckBug52534(){ $check = array(1 => 'a', -1 => 'b'); $str = var_export($check, true); $str = "\$a=$str;"; eval($str); if (!isset($a[-1])) return true; } echo (Checkbug52534()) ? "has it" : 'not found'; -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
