similar to: dhclient-eth0.conf question

I have a test CentOS 4.4 workstation that I am trying to configure to use vendor options from a W2003 DHCP server. A vendor class with the custom options has been created on the windoze box and I seem to be receiving the info in the vendor-encapsulated-options shown in the lease file. What I don't know is how to decode these options so that the CentOS client uses them. I have searched the web

Hi all :-) on centos 6 I need keep the hostname from a dhcp server: cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 HWADDR=00:50:56:27:0E:C8 TYPE=Ethernet UUID=20924b21-e92a-4944-a054-06d1967155c1 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp PEERDNS=yes with this config, centos keep only ip from dhcp server (not gw, not dns) where is dhclient.conf? I need to create it? If yes,

It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with "-cf /etc/dhclient-$(DEVICE).conf", and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of "DHCP_HOSTNAME" in ifcfg-eth0 you can specify a host name, but because of the above behavior of

Hello, I have a problem which is that some of my VMs are loosing there IP addresses from time to time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST send from the VM by dhclient and the server responded only 50 minutes later ! Any help, advise on how to debug would be welcome. Thanks in advance Patrick Here after is an extract from the log July 1st 2016,

Hi all, I have setup my Cisco 79XX phone. Did the tftp, put the config files in the right location with the right names. Booted my phone, it does the tftp things, the screen shows my extensions everything seems fine. However, when I come offhook and try to dial 11 which is just a playback of demo-congrats in the dialplan the phone says Calling Out (INV) below is my sip.conf file - I presume it

qemu in SLIRP mode offers DHCP services to the appliance. We don't use them, but use a fixed IP address intead. This changes the appliance to get its IP address using DHCP. Note: This is only used when the network is enabled. dhclient is somewhat slower, but the penalty (a few seconds) is only paid for network users. We could consider using the faster systemd dhcp client instead. ---

I did the following to setup the tftp server. Download tftp from ftp://ftp.kernel.org/pub/software/network/tftp/tftp-0.40.bz2 tar -jxvf tftp-0.40.bz2 cd tftp-0.40 make make install mkdir /tftpboot chmod 777 /tftpboot chown nobody:nobody /tftpboot changed /etc/xinetd.d/tftp file to "disable no" service xinetd restart Now when I connect I get in /var/log/messages "tftpd: read(ack):

Hi, I have CentOS 7 and I am trying to get dhclient hooks working. I have 1) created file /etc/dhcp/dhclient-enp4s0.conf, 2) created directories /etc/dhcp/{dhclient-enter-hooks.d, dhclient-exit-hooks.d}, 3) added line 'DHCLIENTARGS="-nc"' into file ifcfg-enp4s0 and 4) added file /etc/dhcp/dhclient-enter-hooks.d/test with line echo "executed enter-hook", 5) but I was

Hi all. I recently turned net.inet.udp.log_in_vain on on some of my boxen and have been seeing UDP connection attempts to port 67 on the local host. This initially seemed odd, as the target ip addres was indeed that of a DHCP-configured interface and the source address was that of my DHCP server. However, it turns out this is totally valid, as dhclient(8) does not bind(2) on the bootpc port but

Hi all, I have setup tftp on centos 4 before an it worked. I am not setting up tftp on centos 5. I have added many -v -v -v -v to the tftp config file. /var/log/messages shows me connection from the IP address - but no errors. My client eventually times out as the file is not being provided. It works by the way on localhost, just not from a client. selinux is turned off. I iptables turned

Hello, I''m using shorewall-4.5.16 with centos5. The dhclient stores the lease information on the /var/lib/dhclient/dhclient-<DEVICE>.leases file. The /var/lib/shorewall/firewall script has the function detect_dynamic_gateway that detects the gateway based on the leases file. The code in the function is: detect_dynamic_gateway() { # $1 = interface local interface
