pesky multiple eth addresses in SuSE 10 with same MAC.
Navigate to the hotplug file in the /etc/sysconfig directory:
# cd /etc/sysconfig
Open the hotplug file in an editor.
Set HOTPLUG_PCI_QUEUE_NIC_EVENTS to yes:
HOTPLUG_PCI_QUEUE_NIC_EVENTS=yes
Run the command:
ifconfig -a
Make sure that the interface name to MAC address mapping remains same across the reboots.
For each ethernet interface displayed, do the following:
If a file named /etc/sysconfig/network/ifcfg-eth-id-mac, where mac is the hardware address of that interface, does not exist, then do the following:
Create the file.
If a file exists for the same network interface with the name /etc/sysconfig/network/ifcfg-ethX, then copy the contents of that file into the newly created file. The variable ethX represents the interface name.
Add the following line at the end of the file /etc/sysconfig/network/ifcfg-eth-id-mac.
PERSISTENT_NAME=ethX
where ethX is the interface name.
For example:
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:02:B3:DB:38:FE
inet addr:10.212.99.30 Bcast:10.212.99.255
Mask:255.255.254.0
inet6 addr: fe80::202:b3ff:fedb:38fe/64 Scope:Link

RX bytes:35401016 (33.7 Mb) TX bytes:999899 (976.4 Kb)
Base address:0xdce0 Memory:fcf20000-fcf40000
If a file named etc/sysconfig/network/ifcfg-eth-id-00:02:B3:DB:38:FE does not exist, do the following task:
Create the file.
If the file /etc/sysconfig/network/ifcfg-eth0 exists, then copy the contents of this file into etc/sysconfig/network/ifcfg-eth-id-00:02:B3:DB:38:FE.
Add the following to the end of the file named etc/sysconfig/network/ifcfg-eth-id-00:02:B3:DB:38:FE,
PERSISTENT_NAME=eth0
Perform the procedure for all the interfaces that the ifconfig -a command displays that you need across boots.
To configure interfaces to be up before starting LLT
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:02:B3:DB:38:FE
Where eth0 is the sample network interface name. The output displays 00:02:B3:DB:38:FE as the interface's MAC address.
Navigate to the config file in the /etc/sysconfig/network directory:
# cd /etc/sysconfig/network
Open the config file in an editor.
Append the string eth-id-macaddress to the MANDATORY_DEVICES list in the config file. Separate each address with a space, for example:
MANDATORY_DEVICES="eth-id-00:02:B3:DB:38:FE"
Next, edit /etc/udev/rules.d/70-persistent-net.rules
Add the following:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:02:B3:DB:38:FE", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
Finally, edit /etc/udev/30-net_persistent_names.rules and have the SYSFS address match the interface MAC. Remove lines of interfaces that do not exist.
SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:02:B3:DB:38:FE", IMPORT="/lib/udev/rename_netiface %k eth0"
Reboot!
i'm learning new things every day. trying to do a little ssh bash -c action, i get this error: sudo no tty present and no askpass program specified at the top of the system's /etc/sudoers file, add the following: Defaults visiblepw
So, I decided to update a nice old system that does temperature graphing for us. The first issue was the lack of various pms that the perl scripts required. Once that was tackled, I found that the local device graph function was working. But, my netcat grabs were not . So, yes, I could echo and printf my life away and get my values, but in a script, this: my $values = `echo "GET /temp HTTP/1.0\n\n" |nc my.temp.sys 80 `; Did not work. Not at all. So, I thought and thought and did a little digging, and sure enough there’s a registered bug with nc when one wants to pipe data to it. To get those values, here’s what the line’s to look like: my $values = `echo "GET /temp HTTP/1.0\n\n" |nc my.temp.sys 80 -q -1`; So, if you’re using newish ubuntus, 10+, now you know.

sigh. i need to add an additional data source to my rrd file. in my specific case, a new temperature probe; probe 7. i also managed to forget the specifics of the rrd. that's okay. # rrdtool info /var/stats/rrd/envmon/temp.rrd filename = "temp.rrd" rrd_version = "0003" step = 60 last_update = 1388770922 ds[probe1].type = "GAUGE" ds[probe1].minimal_heartbeat = 300 ds[probe1].min = 5.5000000000e+01 ds[probe1].max = 9.5000000000e+01 cool. we have the step and type and heartbeat and min and max. # cpan install RRD::Simple script... #!/usr/local/bin/perl use strict; use RRD::Simple (); my $rrd = RRD::Simple->new(); my $rrdfile=$ARGV[0]; my $source=$ARGV[1]; my $type=$ARGV[2]; chomp($type); $rrd->add_source($rrdfile, $source => $type); ... script usage: ./addSource.pl file.rrd ds GAUGE e.g.: # ./addSource.pl /var/stats/rrd/envmon/temp.rrd probe7 GAUGE:300:55:95that wasn't so hard.
