What's the right way to assign an IP alias to an ethernet interface that you want to bring up and down manually, not on boot? I tried the old way of making an ifcfg-eth3:0 file and it does work with the ifup, ifdown commands, but even though I specified onboot=no, it activated at boot-up. -- Les Mikesell lesmikesell at gmail.com

I know this was discussed before, and I have seen a million ways of doing this via online docs. I have a quick question that hopefully the community can help me out with I am trying to add a block of 10 IP addresses. Rather then create 10 different alias files, I want to use the RANGE file. Docs say to use the following format: IPADDR_START=x.x.x.x IPADDR_END=x.x.x.x CLONENUM_START=0 If the

Hi, I accidentally found that the existence of a file e.g. named ifcfg-eth1:1 put in /etc/sysconfig/network-scripts/ leads to the appropriate interface being created even with the option 'ONBOOT' set to 'no': DEVICE="eth1:1" BOOTPROTO="static" NM_CONTROLLED="no" ONBOOT="no" TYPE="Ethernet" IPADDR=12.34.56.78

H? all; i need your helps on setting the virtual ip. I am trying to setup static virtual ip on CenOS7. but I want my VIP to should not open when rebooting. My interface settings like this: *for ens33 NIC -> ifcfg-ens33* DEVICE=ens33 BOOTPROTO=none ONBOOT=yes PREFIX=24 IPADDR=192.168.2.151 *and for VIP NIC ens33:2* * -> ifcfg-ens33:2* DEVICE=ens33:2 ONBOOT=no ONPARENT=no

Hi, I have an eth0 interface (it's a CentOS 6 guest VM on a KVM host) which is configured as follows (see below) with a primary public IP address of xxx.xxx.xxx.130 (which works fine). I cannot set an alias IP address. I want eth0 to also use another IP address (xxx.xxx.xxx.131, so I create /etc/sysconfig/network-scripts/ifcfg-eth0:1. Then: # service network restart Shutting down

In CentOS 5.7 and earlier versions, an alias interface is defined via ifcfg-<interface>:foo which contains "ONBOOT=no". The ONBOOT setting appears to be ignored, and the interface always starts when the system boots or if networking is restarted. This is a serious bug that seems to date back many years (I found references in 2005). Anyone know why it hasn't been fixed, or

We use a dual homed CentOS-6.3 host for our Internet gateway router. Its internal nic (eth1) is configured such that the address 192.168.0.1 is one of its aliases. # cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none BROADCAST=192.168.255.255 DEVICE=eth1:192 IPADDR=192.168.0.1 IPV6INIT=no MTU="" NAME="LAN - Non-routable" NETMASK=255.255.0.0 NETWORK=192.168.0.0

CentOS-6.6 We have a host that has multiple IPv4 addresses aliased to eth0. The primary address is 216.185.71.x and the alias is 192.168.6.x. This host connects to devices on both netblocks without problems. Only default routing is used and it looks like this: #ip route 192.168.6.0/24 dev eth0 proto kernel scope link src 192.168.6.x 216.185.71.0/24 dev eth0 proto kernel scope link src

Ok, im using the RSAT tools so howto get more info and fix this. Start Active Directory Sites and Services Klik on Sites, Default-First-Site-Name - Server. Your should see you second DC also, if not, you can add it manualy. I dont know the samba-tools commands for this one. In the DNS admin. Go to _msdcs.YOURDOMAIN. Look at the aliasses. These are the names you need in Active Directory

Arch = x86_64 OS = CentOS-6.4 (centos) with all updates applied to date. On our gateway host eth0 is the WAN access and eth1 is the LAN. I wish to activate the address 192.185.71.1 on eth1. The ifcfg-eth1:192071 file contains this: NAME="" BOOTPROTO=none MACADDR="" IPV6INIT=no DEVICE=eth1:192071 NETMASK=255.255.255.0 MTU="" BROADCAST=192.168.71.255 ONPARENT=no

I am trying to work out what all the options are for migrating a KVM machine to another KVM machine, without using shared storage. The documentation is not quite verbose and not intuitive, so I'm hoping someone can explain this to me. The man pages show this syntax: migrate optional --live --p2p --direct --tunnelled --persistent --undefinesource --suspend --copy-storage-all --copy-storage-inc

I''ve been using Puppet now for a month or so and I''ve come to a problem that may warrant an additional Puppet metaparameter. I''m advocating the addition of a metaparameter called "preaction" (or something like that), which will perform some arbitrary action before the resource is modified. There may be a way to do this within Puppet already (with some

Hi all, I'm trying to activate sieve. In all tutorials I have seen I need to set dovecot_destination_recipient_limit = 1 in Postfix's main.cf. Can anyone explain why ? I like to know because when I set this and the dovecot transport in Postfix, I'm having problems when aliasses are used that map to different recipients, i.e. info at ... results in user1 at ..., user2 at ...,

HPA, a longterm reminder. See below. Can you also make a LABEL ignore other labels if no KERNEL statement is found in between? That way you could define multiple aliasses for an entry. label foo label bar label memtest kernel memtestp foo ignores 'label bar' , 'label memtest' and executes 'kernel memtest' bar ignores 'label memtest' and executes 'kernel

Hello, I'm following instructions in http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.LVS-DR.html#route_on_non_ip_interface to allow my xen guest real hosts to serve virtual IP's behind LVS without having to allocate real public IP addresses for each such xen guest. I have eth1 connected via a "back-end" switch to the eth1/xenbr1 of the xen host and the other physical

Hi, I ran into a Problem when using alias interfaces with vlans on a centos 5 box. When I define such an interface and do a "service network restart" the alias interface doesn't get started. Starting it manually works fine. Also after changing DEVICE=eth0.10:0 to DEVICE=eth0:0 in the config file the interface is started after a network restart. Does anyone have an idea what the

Hi, I recently moved from courier-imap to dovecot, to be able to work with managesieve. I use version 1.2.5, on suse 10.3. I used the script to migrate the courier maildir to dovecot format. It seems to work fine except for one problem : I use a number of aliasses and with Thunderbird I can select which alias (e-mail-address) to use as my identity when sending a mail. I sniffed with wireshark,

I have a recently installed Mellanox VPI interface in my server. This is an InfiniBand interface, which, through the use of adapters, can also do 10GbE over fiber. I have one of the adapter's two ports configured for 10GbE in this way, with a point to point link to a Mac workstation with a Myricom 10GbE card. I've configured this interface on the Linux box (eth2) using

Hello /etc/sysconfig/network-scripts/ifcfg-eth0 looks like this: # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) TYPE=Ethernet NAME=eth0 NM_CONTROLLED=no IPV4_FAILURE_FATAL=yes UUID=cc2635ff-3c14-48ba-b19a-84c5b9d36a9d ONBOOT=yes DEVICE=eth0 BOOTPROTO=none HWADDR=00:50:56:01:00:01 BROADCAST=192.168.0.255 IPADDR=192.168.0.10 NETMASK=255.255.255.0 NETWORK=192.168.0.0

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue
