Re: [CentOS] Embedded Question-Stateless readonly filesystem

Yes This technology preview is amazing . Hope Karan never stop this development. I am trying to make a readonly root filesystem for asterisknow 1.5 which uses centos 5.3 ,if it this works will be amazing.It will always ensure asterisknow1.5 boot cleanly even improperly shutdown or on crash.

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.

Hi All, I am using rsync and I see --exclude as an option. But it says --exclude pattern? So how can I do an rsync on '/' except exclude /home/nackup? I am doing: rsync -avx / /mnt/sdb2/ can I simply do: rsync -avx --exclude=/home/backup / /mnt/sdb2/ -ML

Huge!
by ML 06 Oct '09

06 Oct '09

Hi All, I was trouble shooting why an rsync was taking over a day. I found the problem to be in in a directory in /home that has CVS backups in it. I browsed to find out that there are 7 .tar.gz archives that are each about 1199943181 in size. So that is over 11gb each? If I am doing the math in my head right.... No wonder why this is taking forever to rsync to a USB drive. It was only on the second of 7 and I started it at 2pm yesterday and it was not done/going this morning.... -ML

More about firewalling
by ML 06 Oct '09

06 Oct '09

Hi All, So before when I used PIX's for my employer, our traffic was statically routed to one IP and then the firewall decided if allowed/ denied and passed it on or dropped it. I have a Comcast business circuit with 13 IP's. The gateway device they provide is a 'pass through' device. They sent traffic for all 13 IP's my way. It just allows traffic through. So if I put in a device to firewall (like Ipcop or Vyatta or something) in front, say it has 3 NICS, how do I do that? If the Firewall has IP A and Traffic for IP B comes in how would IP A answer and decide if the traffic to IP B belonged? Without statically routing I am confused on how to accomplish this? How fast does this device need to be? Best, -Jason
