I was concerned that if, during the C7 install, I put the bootloader on sda that it would wipe out what was already there and prevent me from booting F20. Apparently this is not the case. However, I decided to put the bootloader on sdb so I could easily wipe out the C7 install and use the drive for something else. I did the install from the C7 DVD disk. Maybe I missed something but once I indicated I only wanted to use the sdb disk (checkmark on icon), I did not have the option as to where to put the bootloader. After the install, when I boot the computer I go directly to F20. If I press the ESC key when booting I get a BIOS bootloader menu. Miraculously, sdb is on the list. Apparently the BIOS is smart enough to recognize that sdb is bootable and, therefore, puts it on the list.

[CentOS] Dual boot with 2 drives
Hi, I have a laptop with 2 hard drives. The first has Fedora 20 (no windows or anything else) and the second is unused. I would like to install CentOS7 on the unused drive so I can dual boot with the choice of the 2 OS's on the Grub menu. I am comfortable in partitioning drives and installing Linux distributions. I am afraid I may mess up the MBR and/or set up Grub incorrectly so I lose everything. Please point me to some documentation to help me.

I am currently using, as a server, a workstation computer. It was built with a gigabyte motherboard and has 8G ram and a 1000G Sata 3 drive. It is accessed with ssh and runs an ftp server, a web server and a samba server so my wife can back up her pc to it. It is running behind a router. This computer more than meets my needs as a lightweight server except the hardware is dying and I want to replace it. The question in my mind is: should I just buy another workstation class motherboard and duplicate what I already have or buy a motherboard which is intended to be used as a server?

[CentOS] Set static IP
Hello, I want my CentOS 6.5 computer to have a static IP. Currently I get the IP I want because I have my router assign it on the basis of mac address. I placed the following file as: /etc/sysconfig/networking-scripts/eth0 DEVICE="eth0" BOOTPROTO=static HWADDR=00:1F:D0:9E:AE:67 ONBOOT=yes TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes NETMASK=255.255.255.0 IPADDR=192.168.0.99 GATEWAY=192.168.0.1 NM_CONTROLLED=no I also disabled Network Manager with chkconfig. It didn't work. When I rebooted I had no IP address for eth0. Should I leave all the other scripts in /etc/sysconfig/networking-scripts unchanged? Suggestions would be appreciated.

[CentOS] Samba problem
Hello, My only hard drive failed on a private server so I had to replace it and reinstall Centos 6.5 and Samba. My smb.conf file is OK according to "testparm". I configured smb and nmb, with chkconfig, to start when the system boots. After the system boots if I do "service nmb status" I get the response "nmbd dead but pid file exists". I can delete the pid file manually and start nmb with "service nmb start". The problem is that when the system shuts down and restarts I still find that "nmbd dead but pid file exists". Any suggestions on how to fix the problem would be much appreciated. Thank you, Joe ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Change server name in postfix configuration
Hi, A consultant, long gone, set up postfix, dovecot, amavisd and squirrelmail for my wife. It works fine but my wife wants to change the server name from old.com to new.com so the name is more appropriate for her business. My approach would be to use sed to change all occurences of old.com to new.com. Specifically, I used grep to identify the following files where I should make the changes. /etc/postfix/main.cf /etc/dovecot/dovecot.conf /etc/squirrelmail/config.php /etc/amavisd.conf /etc/sysconfig/network (change host name) In addition, there would be an MX record for mail.new.com pointing to the IP of the server. My question is, will this work or will I corrupt my email server? If I mess it up I can always restore it to the original.

Hi, Because of heavy interference in the 2.5GHz range in my neighbourhood, I want to switch to wireless dual band (5GHZ) and wireless ac.

[CentOS] Problem with cron
I have a root cron job that powers down my server every day at 1am and 6pm. The output of '# crontab -l' is shown below. * 1,18 * * * poweroff Last night, after the server powered down at 6pm, I decided I wanted to use the server so I started it with the power button. The server, after a minute or so, powered itself down. This behaviour happened repeatedly until I waited past 7pm. Then the server did not poweroff. Apparently a cron job that executed correctly at 6pm was executing minutes past 6pm when the server was restarted. This is totally unexpected behavior. Here is the output of the cron log file. The name of the server has been redacted. # grep -i 'Feb 22' cron-20140223 | grep -i poweroff Feb 22 18:00:01 xx CROND[2875]: (root) CMD (poweroff) Feb 22 18:12:01 xx CROND[1894]: (root) CMD (poweroff) Feb 22 18:16:01 xx CROND[1893]: (root) CMD (poweroff) Feb 22 18:18:01 xx CROND[1896]: (root) CMD (poweroff) Feb 22 18:22:01 xx CROND[1915]: (root) CMD (poweroff) Feb 22 18:25:01 xx CROND[1919]: (root) CMD (poweroff) Feb 22 18:34:01 xx CROND[1890]: (root) CMD (poweroff) Is there a fix for this behavior?

[CentOS] CentOS 6.4, LAMP, MariaDB
Hi, I am trying to install a LAMP stack using MariaDB on CentOS 6.4, 64 bit. I have installed MariaDB by using the MariaDB repository configuraton tool. I installed php by itself. Both MariaDB and php individually test fine. I know that php-mysql has to be installed to complete the LAMP stack installation. From lots of googling I understand that there is a php-mysql and a php-mysqlnd. If I do: # yum list | grep -i php-mysql I only get php-mysql, not php-mysqlnd, even though the MariaDB repository is active. Will php-mysql work or should I try to find mysqlnd? FYI: I installed LAMP with MariaDB on a Fedora 19 box and, I don't remember how, php-mysqlnd was installed.

[CentOS] Should I upgrade Samba 3.6 to Samba 4.1
Hi, I just installed Samba on my Centos 6.4 computer. Smbstatus says my version is 3.6.9-151.el6-4.1. My smb.conf file only has a [global] and [homes] section. My configuration works, as expected, from a Win7 Virtual Box computer and a Win8 Virtual Box computer. I can see the share from the Windows file explorer and can map the share to a network drive. The Samba server is not virtual. The problem is my wife's Win7 laptop which is running some sort of home edition of Win7. I did everything I could in control panel to enable file sharing but I still can't see the Samba share. I can ping the computer running Samba? I tried to launch "gpedit.msc" but this program was not there. Do you think it would work if I upgraded Samba to the latest version 4.1? Should I consider upgrading to Win7 professional? Thank you, Joe Hesse ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

What worked for me is to have a Windows user with the same name as the user on the CentOS computer and set a Samba password to be the same on both machines. What confused me is that many times I log on to a service on another computer and only have to know the name and password of the computer I am logging in to. My real home network consists of my wife's Windows computer and multiple Linux desktops. I backup my computers using rsync. For the windows computer I looked at Cygwin which has the rsync program but decided instead to map a drive letter on her computer to a Samba share. She then could use the Windows backup program and backup to the Samba share. Afaik, the Windows backup program mirrors the selected files on the backup device. She has no need of restoring files prior to a certain date. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

My Win7 virtual machine still couldn't see the share. It is my impression that the smb.conf file in the book I am using allows passwordless access to the shares.

[CentOS] Samba problem
Hello, I am trying to learn how to use Samba. I first just want to get it to work, then I'll make it better. I am not concerned about security since everything is on a private network. I am following the material in "CentOS 6 Linux Server Cookbook" by Jonathan Hobson. I am using two virtual computers with Virtual Box running on Fedora 19. Both virtual computers have bridged networking. One virtual computer is Win7, the other is CentOS 6.4. They are both up to date. There is only one user, "admin", on the CentOS virtual computer. The Win7 computer can successfully ping the CentOS computer. My Win7 computer can not see the share on the Samba server. The command "# testparm" shows no errors. The command below gives the following error: [admin@CentOS ~]$ smbclient //CentOS/admin Enter admin's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.9-151.el6_4.1] tree connect failed: NT_STATUS_ACCESS_DENIED My smb.conf file, below, is taken from the book I am using.

[CentOS] fstab, unusual behavior of "missing UUID"
I have the following as the last line of my /etc/fstab file on a computer running CentOS6.4.. UUID=3b550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2 The UUID refers to an ext3 partition of a removable USB drive. If the USB drive is not plugged into the computer the computer will not boot. It seems that this is the incorrect behavior since "noauto" means there is nothing to mount. I noticed this situation since an almost identical /etc/fstab on a Fedora 18 computer will boot without the USB drive being plugged in. The reason this is important to me is that I want to plug my USB drive into a running computer and then mount it with "# mount /mnt" so I can do backups.

[CentOS] sda and sdb reverse order with an external USB drive
Hello I am using 64 bit CentOS 6.4 on an i7 laptop with one sata drive and a CD drive. I installed CentOS by manually partitioning sda as: sda1 as /boot, sda2 as swap, sda3 as /. The booted system works great. When I insert an external USB drive, formatted as ext3, the hard drive on the laptop and the USB drive are either sda or sdb, depending upon the order on which I insert the USB drive and boot the system. Please see the two mount commands below for each of these situations. This seems to work in either order except for the fact that I don't want my USB drive to automount. What I want is that after I insert the USB drive in a running system and wait 15 seconds, I want to mount the USB drive with the command "# mount /mnt". To accomplish this I added a line to /etc/fstab but it didn't work. When I uncomment the last line in fstab (see below) the computer hangs and doesn't boot. I was successful with this strategy on a similar laptop with Fedora 18 but not my current one. Thank you, Joe Hesse The following mount command was issued by first completely booting CentOS and then inserting the external USB Drive. Note the sda3 is / and sda1 is /boot. [root@XoticPC ~]# mount /dev/sda3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) /dev/sdb1 on /media/GoFlex type ext3 (rw,nosuid,nodev,uhelper=udisks) The following mount command was issued by inserting the external USB drive in a powered down computer and then booting. Note the sdb3 is / and sdb1 is /boot. [root@XoticPC ~]# mount /dev/sdb3 on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sdb1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) /dev/sda1 on /media/GoFlex type ext3 (rw,nosuid,nodev,uhelper=udisks) The /etc/fstab file was generated by the install process. The commented line at the bottom was added by me in an unsuccessful attempt to be able to insert the USB drive in a booted computer, not having it mount, and then control the mounting with "# mount /mnt". The last UUID is the UUID of sdb1 determined with the command "# blkid /dev/sdb1". # /etc/fstab UUID=1d7606b7-46b8-4b29-9a4e-a50a1f6a1759 / ext4defaults1 1 UUID=e0fdfeb1-e7a7-4a06-b5fa-7730c3c2e60d /boot ext4defaults1 2 UUID=d0e3c2ee-7c66-4d13-b387-1da958020b1a swap swapdefaults0 0 tmpfs /dev/shmtmpfs defaults0 0 devpts /dev/ptsdevpts gid=5,mode=620 0 0 sysfs /syssysfs defaults0 0 proc/proc proc defaults0 0 #UUID=3b550884-8d05-41a5-a205-17b6d7269dd1 /mnt ext3 rw,suid,dev,exec,noauto,nouser,async 0 2 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
