Back before the inexpensive routers, and before the fairly easy to find specialty loads. The thing that got me away from it was it was my only Linux system at the time, and a botched update ended up with me having an unbootable system. And an emergency trip to Staples to buy the distribution they had there. A couple days without a protected home network, and I decided to eventually go with a dedicated box. Things would be different if I wanted to get fancier than what these standalone systems provided. But right now, I don't need the extra capability.

CentOS-5.3 Inactive device reports error - bugzilla:465442
by James B. Byrne 07 Oct '09

07 Oct '09

I am seeing this in the syslog when starting a multi-homed CentOS-5.3 host. Oct 6 08:35:04 inet04 nm-system-settings: initial_add_devices_of_type: could not get device from HAL: An SELinux policy prevents this sender from sending this message to this recipient (rejected message had interface "org.freedesktop.Hal.Manager" member "FindDeviceByCapability" error name "(unset)" destination "org.freedesktop.Hal") (9). Which appears to be this bug: https://bugzilla.redhat.com/show_bug.cgi?id=465442 However, I cannot tell from the bug description and commentary what is actually going on. What does this message mean and how is the situation reported rectified? I speculate that this error is somehow related to the fact that eth1 is not activated on boot by intent, but I cannot tell for sure. If anyone has the explanation of what is happening, what it means, and how this is fixed I would appreciate learning it. Regards, -- *** E-Mail is NOT a SECURE channel *** James B.

trying to understand OSS, GPL, BSD & other licensing model for software distribution.
by Rudi Ahlers 07 Oct '09

07 Oct '09

Hi all, We are busy developing some software (some is web based, others not) and I am having a bit of hard time understanding (or rather, choosing) a license model to work with, We will offer some free software (PHP based scripts, and even Windows based applications) and for this I'm sure the GPL, or even LGPL (for the network side?) will work fine. But, we also need to suppose these scripts, and will be charging for support (other for installations, customization, or even custom derivations, etc), but at the same time we need to distribute some commercial software to cover developer's salaries, rents, marketing, business growth, etc. Now, my question(s) is as follows: Can I sell one script as GPL, but another as AGPL, or even BSD under the same company name? And if these 2 are tied together (i.e. being able to be used together, although seperate programs / script - for example Apache + PHP), how would I license them? We are writing a series of PHP + MySQL based scripts which can be used on the internet, either stand-alone, or in conjunction with other scripts (API driven), and I want to offer a free, limited edition, as well as commercial edition with more features. We're also writing some software that makes use of MySQL / sqlite / postgresql, and even MSSQL, so I need to take their licenses into consideration. What would be the best license for this? I know it's broad, but there's just too much to readup on the different licences and I've read a lot already, not knowing where to go. I have a feeling that I may need to go the dual / multi-license route, but even then I don't know which licences to use. The open source projects wouls also be open for other people to add their own modifications, but I would also like to allow others to write commercial addon's as well. Any pointers, and even past-experiences? -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

problem installing centos 5.3 on IBM x3200 m2
by Janez Kosmrlj 07 Oct '09

07 Oct '09

Hi, I am trying to install centos 5.3 on ibm x3200 m2 server. The problem appears when the installer is about to finish the installation. It detects the RAID correctly, but it doesn't finish formatting the root partition. I tried the default partition layout and also a custom one, but it always ends with the same message: An error occurred trying to format /. this problem is serious and the install cannot continue. I also checked the error console (ctrl+alt+F4) and it writes: <3> sd 0:1:10:0: rejecting I/O to offline device lspci says that the machin has an: LSI Logic SAS1064ET PCI-Express SCSI controller Broadcom NetXtreme BCM5722 Ethernet Has anybody an idea, how to fix this?

Yes This technology preview is amazing . Hope Karan never stop this development.

ifconfig showing same mac for 2 nics in same bond
by aurfalien＠gmail.com 07 Oct '09

07 Oct '09

Hi all, I just noticed that my two nics that are bonded via mode 0 are showing the same mac addy in ifconfig. Is this normal because of the nature of my bond? In syslog I keep getting; kernel: pbond0: received packet with own address as source address Some guidance is appreciated before I dive in and troubleshoot. If I don't list the mac addy in my ifcfg-th# files, only one of the 2 nic comes up during boot. If I turn off bonding, then each nic shows its correct mac addy. This leads me to believe that since my switch isn't config'd for bonding when in mode 0, that the mac addy must be duplicated amongst all members of the bond in order for packets to be distributed; ie the bond to work in round robin fashion. uname; 2.6.18-128.7.1.el5xen /etc/modprode.conf alias eth0 tg3 alias eth1 tg3 alias eth2 forcedeth alias eth3 forcedeth alias scsi_hostadapter2 mptsas alias scsi_hostadapter mptspi alias scsi_hostadapter1 mptfc alias scsi_hostadapter2 mptsas alias bond0 bonding options bond0 miimon=80 mode=0 alias peth0 tg3 /etc/sysconfig/network-scripts/ifcfg-eth0 # Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet DEVICE=eth0 BOOTPROTO=none USERCTL=no HWADDR=00:23:8B:CE:9C:5C ONBOOT=yes MASTER=bond0 SLAVE=yes TYPE=Ethernet /etc/sysconfig/network-scripts/ifcfg-eth1 # Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet DEVICE=eth1 BOOTPROTO=none USERCTL=no HWADDR=00:23:8B:CE:9C:5D ONBOOT=yes MASTER=bond0 SLAVE=yes TYPE=Ethernet /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 IPADDR=10.0.70.11 NETMASK=255.255.0.0 NETWORK=10.0.0.0 BROADCAST=10.0.255.255 GATEWAY=10.0.10.1 ONBOOT=yes BOOTPROTO=none USERCTL=no TYPE=Ethernet ifconfig output; bond0 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C inet addr:10.0.70.11 Bcast:10.0.255.255 Mask:255.255.0.0 inet6 addr: fe80::223:8bff:fece:9c5c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10714 errors:0 dropped:0 overruns:0 frame:0 TX packets:386 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1157674 (1.1 MiB) TX bytes:37307 (36.4 KiB) eth0 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:5618 errors:0 dropped:0 overruns:0 frame:0 TX packets:192 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:694966 (678.6 KiB) TX bytes:20541 (20.0 KiB) Interrupt:21 eth1 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:5570 errors:0 dropped:0 overruns:0 frame:0 TX packets:191 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:685771 (669.6 KiB) TX bytes:19584 (19.1 KiB) Interrupt:22 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2111 errors:0 dropped:0 overruns:0 frame:0 TX packets:2111 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5464730 (5.2 MiB) TX bytes:5464730 (5.2 MiB) pbond0 Link encap:Ethernet HWaddr 00:23:8B:CE:9C:5C inet6 addr: fe80::223:8bff:fece:9c5c/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:11188 errors:0 dropped:0 overruns:0 frame:0 TX packets:383 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1380737 (1.3 MiB) TX bytes:40125 (39.1 KiB) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask: 255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:468 (468.0 b)

Experimenting with CentOS IPA Server
by Clint Dilks 06 Oct '09

06 Oct '09

Hi Everyone, I have been able to install all of the RPMS related to the recently announced CentOS IPA server and am at the point where I have run /usr/sbin/ipa-server-install. This completes but I see the following output which concerns me [8/16]: creating indices root : CRITICAL Failed to load indices.ldif: Command '/usr/bin/ldapmodify -h 127.0.0.1 -xv -D cn=Directory Manager -y /tmp/tmpszemr6 -f /usr/share/ipa/indices.ldif' returned non-zero exit status 68 Looking in the log I see this ldapmodify: Already exists (68) 2009-10-07 11:33:50,781 CRITICAL Failed to load indices.ldif: Command '/usr/bin/ldapmodify -h 127.0.0.1 -xv -D cn=Directory Manager -y /tmp/tmpszemr6 -f /usr/share/ipa/indices.ldif' returned non-zero exit st atus 68 So I am assuming this means the ldif is already in place ? Or is this an issue I should be trying to diagnose further ? Thanks for any insight you can offer :)

Access host from host
by Paras pradhan 06 Oct '09

06 Oct '09

HI, I don't know if this is the right place to ask but here is what I am looking for. I have a centos 5.3 server in DMZ . All of the access to and fro is blocked. I have someother servers in my network which they can access to my server at DMZ. Now to connect to the server "directly" at DMZ (ssh, rdp. ftp), is it possible to allow access via the accessible another servers? Thanks Paras.
