java 1.6 and 1.7 on CentOS
by Asma rabe 22 Aug '14

22 Aug '14

Hi , I have java 1.7 installed on CentOS machine. when i tried to run java program i got an error and found that i should run it using java 1.6. Is the best solution to install Java 1.6 and have both java 1.6 and java 1.7 at same time? or is there a better solution. If i should install both java 1.6 and 1.7 , how to do that ? Thank you very much. Best Regards, Asma

Centos 7 lockup

A machine I set up to run OpenNMS stopped working last night - no hardware alarm lights, but keyboard/monitor/network unresponsive. After a reboot I see a large stack of messages like this in /var/log/messages: ---- Aug 20 14:02:34 opennms-h-03 python: SELinux is preventing /usr/sbin/monitor-get-edid-using-vbe from mmap _zero access on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************* If you do not think /usr/sbin/monitor-get-edid-using-vbe should need to mmap low memory in the kernel. Then you may be under attack by a hacker, this is a very dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ****************** If you want to allow mmap to low allowed Then you must tell SELinux about this by enabling the 'mmap_low_allowed' boolean.

And where else should I look for the underlying problem? -- Les Mikesell lesmikesell(a)gmail.com

Further, I am curious as to what components of Skype on Linux are open to source review and which are not. My recent inquiries have raised the unsettling possibility that recent Skype clients may be designed to permit remote exploitation of host systems by unauthorised entities. -- *** E-Mail is NOT a SECURE channel *** James B.

Trying to override MAC addr
by Robert Moskowitz 21 Aug '14

21 Aug '14

I am trying to override the mac addr. Now this is on an armv7 actually running the F19 kernel and Redsleeve 6, but it SHOULD be standard Centos6 ifcfg-eth0 content. Of course RSEL does not start with a ifcfg-eth0 file, letting network services do all the work, so I am starting from scratch, using the file from one of my C6 boxes with static addressing. My file has in it: DEVICE="eth0" BOOTPROTO=none NM_CONTROLLED="no" ONBOOT="yes" TYPE="Ethernet" NAME="System eth0" DNS1=208.83.67.188 GATEWAY="208.83.67.177" IPADDR="208.83.67.179" HOSTNAME="rigel2.htt-consult.com" IPV6INIT="yes" MACADDR=02:67:15:00:01:79 MTU=1500 And when I restart network, it can't find eth0: # service network restart Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [FAILED] but: # ifconfig eth1 Link encap:Ethernet HWaddr 02:67:15:00:01:79 inet addr:208.83.67.179 Bcast:208.83.67.255 Mask:255.255.255.0 inet6 addr: 2607:f4b8:3:3:67:15ff:fe00:179/64 Scope:Global inet6 addr: fe80::67:15ff:fe00:179/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:254 errors:0 dropped:17 overruns:0 frame:0 TX packets:70 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:26575 (25.9 KiB) TX bytes:6104 (5.9 KiB) Interrupt:87 Base address:0x6000 The assigned MAC addr for eth0 is: 02:c3:04:01:77:c3 The tutorials that I have found on ifcfg-ethN say not to use both hwaddr and macaddr in the same cfg file, but it almost seems that is what is needed? thanks

I no longer have the MAC or HW addrs in ifcfg-eth0. Only in /etc/udev/rules.d/70-persistent-net.rules, and only for name=eth0: # net device () SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="02:67:15:00:01:79", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" but on reboot, I get the error: Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [FAILED] and the ethernet comes up as eth1 and the eth1 line is added to /etc/udev/rules.d/70-persistent-net.rules Almost as if there is something else that needs changing.

I ws going by: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-networkscripts-… which says: MACADDR=/<MAC-address>/ where /<MAC-address>/ is the hardware address of the Ethernet device in the form /AA:BB:CC:DD:EE:FF/. This directive is used to assign a MAC address to an interface, overriding the one assigned to the physical NIC. This directive should *not* be used in conjunction with HWADDR. > > [root@srv-rhsoft:~]$ ifconfig eth1 > eth1: flags=67<UP,BROADCAST,RUNNING> mtu 1500 > inet 62.178.103.85 netmask 255.255.255.0 broadcast 255.255.255.255 > ether 00:50:8d:b5:cc:de txqueuelen 500 (Ethernet) > RX packets 74959980 bytes 25037014848 (23.3 GiB) > RX errors 0 dropped 0 overruns 0 frame 0 > TX packets 67607627 bytes 39867204808 (37.1 GiB) > TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 > device interrupt 16 memory 0xf7cc0000-f7ce0000 >
