Please test that if both the server are communicating with each other at
1Gbps or not via "iperf" tool.

If above gives result of 1Gbps then it will eliminate the NICs problem then
you know that it is a problem with cisco switch only.

Re: [CentOS] Gateway question

[Ashish Yadav]

Hi,

You can define your default gateway in "/etc/sysconfig/network" file,

GATEWAY="192.168.1.1"

After that, restart network services.

# systemctl restart network

Basically, df reads the superblock only and trusts it completely.  du reads
each object and sums them up.

Any running process can keep a deleted file open. This means the space will
still be reserved and seen by df,
but since du will no longer see a reference to that file in the directory
tree, it cannot see those reserved blocks.

Try to see the number of open file which could be causing the problem.

It will not be applied automatically to existing users, you have to do that
manually by running below command,

For an example,

# chage -E 6/30/2015 -m 5 -M 90 -I 30 -W 14 test ( For more information

If you gonna create a new user after making changes into /etc/login.defs
then password policy will be applied automatically
on new user and you can check it by running chage -l username.

 I have a question about the network and Centos 7

 I am experimenting with two C7 installations:
 - On relatively new hardware, configured with fixed IP address in IPV4 only
 - on top of Windows, using VMWare, sharing my windows connection via
 Vmware's bridge with IPV4 only.

 On both configurations, I run a script every five minutes to test the
 network.  The sequence is as follows:
 - Find the default interface using ip route
 - Find that interface's IP address by scanning the output of ip route
 for a match in interface.

 If the above tests fail to resolve, I issue systemctl restart network,
 and post a mail message to myself.  When this happens, the network does
 indeed come back correctly.

 I do the same sequence on Centos 6 installations, (using system network
 restart).

 I find that on Centos 6, I almost never get notified that the restart
 occurred (except when there's a real reason).


The BIG difference is systemd and that affects how the system is configured
for service.

For that reason system network restart will not work in CentOS 6. You
should try service network restart .

IMO, you have to configure sssd.conf properly.

Please add ldap_user_authorized_host = host in your sssd.conf which you
have not configured.
After that please check again.

 traffic for the IP on that network through this single server.

 Server 1 in this example is the server that runs the IPSEC connection.

That is strange!!!




 Yet, when I do a df -h on the directory I mounted the NFS share on, I see
 that it's mounted via NFS as expected:

 nfs1.jokefire.com:/home   20G  3.1G   16G  17% /mnt/home

 So, what do you think could be happening? Why is it that I can't see the
 output I'm expecting just by going df -h???


It could be a bug with either mount, coreutils, the kernel or nfs-common.
Please look for update. That may solve this problem.

 put all those users in a group, and delete all the user ACLs on that

 Hi,

 I often have to deal with relatively obsolete hardware in schools, public

Re: [CentOS] error building php spec file

Hi.

Which CentOS version you using?

If it is CentOS 6 then instead of building it from source, you can use IUS
repo which has latest php packages.

Below is the link for the packages in IUS repo for CentOS 6.

[CentOS] Password Must Change using SSSD in Samba 4.1.10

[Ashish Yadav]

Hi,

I am trying to implement the *password must change at next logon* in CentOS
6.5 client using sssd 1.11.6 where Samba 4.1.10 is my backend server.

Here are the list of things which I have done,

1. I have setup the CentOS to do the Domain login using sssd service. I can
able to login into the CentOS client using Domain user's credentials from
display
and from SSH also, no problem at all.

2. Next thing which I want to implement is that password must change
feature into Samba 4.1.10 server. To do that, I have been using Windows 7
ultimate
which is already in Domain and I am using RSAT tools for users and groups
where I have a option to check password must change at next logon option
for particular user.
After doing that Windows machine is honoring this and telling user to
change the password and allowing user to login after changing the password.

3. As far as the CentOS client is concerned, it was not honoring the
password must change and allowing user to login without asking for password
change using sssd with current password.

Here is the configuration file of sssd service,

[sssd]
config_file_version = 2
services = nss, pam
domains = EXAMPLE
sbus_timeout = 30

[nss]
filter_users = root
filter_groups = root
reconnection_retries = 3

[pam]
reconnection_retries = 3
offline_credentials_expiration = 0

[domain/EXAMPLE]
entry_cache_timeout = 600
entry_cache_group_timeout = 600
min_id = 1000
id_provider = ldap
auth_provider = krb5
chpass_provider = krb5
ldap_schema = rfc2307bis
ldap_uri = ldap://smbad.intra.example.com:390/
ldap_search_base = dc=intra,dc=example,dc=com
cache_credentials = true
krb5_server = smbad.intra.example.com:8880
krb5_realm= INTRA.EXAMPLE.COM http://intra.example.com/


ldap_default_bind_dn = cn=admin,dc=intra,dc=example,dc=com

ldap_default_authtok_type = password
ldap_default_authtok = 6pNEn7Eo3zmz9MxciGLx

4. I have also tried to achieve above thing using command line tool
pdbedit but without any luck. Here is the link 
http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/passdb.html#pdbeditthing

which I have followed.

Please share your thoughts in order to help me and move forward to solve
this problem.

Thanks very much and regards,
Ashishkumar S. Yadav

 Says:
 The netinstall isos do not work with UEFI installs, but the minimal or
 DVD isos do work with UEFI. No versions of CentOS-6.6 will work with
 Secure Boot turned on. Secure Boot must be disabled to install CentOS-6.6.

 I see nothing in the MB documentation about Secure Boot enabled or
 disabled.  Also not a word about UEFI.

 Any suggestions anyone?


Please make sure that your BIOS firmware is up to date. Have you checked
that?

 When I run mount -t nfsd nfsd /proc/fs/nfsd, I get

 mount: unknown filesystem type 'nfsd'

 Does anyone know what I need to do to get nfs working? My thinking is that
 I need to load a module or two, but I don't know where or how to do this
 in Centos. I've seen a few posts referencing Ubuntu which ask the user to
 apt-get particular packages, but its not clear that this is the right
 approach for Centos.


Please refer this for more information, it is quite easy guide for setting
NFS server in CentOS.

  cotrollers to KVM.
  Does anyone done this before? Any advice?


Yes, we have done this for PoC. For PoC, we have not stress tested that.
But one thing for sure that it was not putting too much load on host OS.

If you are planning to run in production then keep a count on RAM, Disk I/O
and CPU
of that virtual machine.

I would update it to CentOS 6.5 so you would have matching Linux

Re: [CentOS-virt] MS-Win7 kvm guest gets dhcp from host bridge

  We have installed a MicroSoft Win7 system as a guest and have joined it
 to our
  MS AD domain. The system runs and has internet access.  However, the IPv4
  address it obtains and the gateway it is assigned are both sourced from
 the
  virtual machine host system and not from our AD DC DHCP server.
 
  To clarify, the virbr0 IP address is 192.168.122.1 and the Windows guest
 has
  that address as its gateway and an IP address in the 192.168.122.0/24
  netblock.  This is not as we desire as the internal addresses we
 regularly
  assign to MS workstations via DHCP are supposed to belong to a different
  netblock entirely.  This permit filtering on incoming and outgoing
 traffic at
  the gateway.
 


1. If I understand you correctly then you want to assign MS-Windows a IP
which should not be from
192.168.122.0/24?

2. If that is yes then you have to configure your DHCP server so that
machine which
is a guest machine should get IP based on their MAC address. In VirtualBox
MAC address is in this range
08:00:27:XX:XX:XX:XX, first three value will be constant for all guests.



  I realize that there is a DHCP service running on virbr0 for the purpose
 of
  provisioning guests with system control traffic but I do not know how to
 limit
  that to its intended purpose and allow another DHCP server to provide
 the IP
  address to the windows guests.  I hope that problem description is not
 too
  confusing.
 
  Can anyone provide me with some guidance on the matter?  Are kvm guests
  required to have either static ip addresses or dhcp addresses provided
 by the
  host system?

 It sounds like what you need to do is create a bridge and then connect
 your virtual machine to the bridge so that it can receive DHCP from the
 external network.  I assume you are using libvirt. If so, check out the
 page below. It may help you get started in the right direction.

 Hello list.

Download the CentOS 6.5 Live ISO from http://www.centos.org/download/.
After that burn that ISO on CD or make a bootable pen drive( For windows
use LiLi is the Live USB creator), install it on one partition of your
choice.

Re: [CentOS] centos 6.4 networking problem

Have you verified MAC address of your two NIC's with their respective
network configuration file? Are they same? Sometime that can cause a
problem.

 The content of these two files was the same as in my 5.9 server. The system
 was working properly at the begining. So I don't understant probably I made
 a bad modification some where.

 For now, I scrapped the 6.4 and push back to 5.9 because of a lack of time
 to get a better understanding of the situation.
 6.0 and up seems to be far different from 5 am I wright?

 Thank's for your help
