In version 3.4.3, I do not see /mnt/persist/ directory. How can I achieve the same functionality in 3.4.3 and further? question 1 2 1 comment http://m.getsatisfaction.com/topics/7665023 7665023 Cumulus 3.4.3 Root user credentials 2018-01-12T18:04:51Z 2018-01-10T04:40:10Z Darshan TM http://m.getsatisfaction.com/people/9310004 https://d2r1vs3d9006ap.cloudfront.net/public/uploaded_images/11151275/IMG_2817_medium.jpg darshan_tm Hi..<br /><br />I have loaded the cumulus OS V 3.4.3 and when I try to access the Switch via SCP using Cumulus user login to upload the license.. I found that only read permission is assigned for Cumulus User.. and I was not able to copy the license key...&nbsp;<br /><br />but I got to know that Tmp folder has write permission and there I copied the license key..<br /><br />Now the challenge is I am not able to access that temp folder from cumulus user login.. for that I need to login via root user..<br /><br />but it is asking me to enter the root user credentials which I am not aware of it.. and I searched in google and found that there will be no password for root user.. but then too it is asking me the password..<br /><br />Can any one let me know the root user credentials so that I can login and activate the license of my switch... question 4 3 1 comment http://m.getsatisfaction.com/topics/7665848 7665848 openstack horizon access 2018-01-11T20:31:52Z 2018-01-11T10:57:17Z shakir http://m.getsatisfaction.com/people/9257314 https://www.gravatar.com/avatar/7cf62a0093cc8178ad19d9be2ea92728?d=identicon&s=55&r=PG shakir_ahmed_ibrahim would like to know how to access the horizon dashboard, on the OpenStack citc cloud flavor question 1 2 1 comment http://m.getsatisfaction.com/topics/7665342 7665342 Spectre, Meltdown vulnerabilities 2018-01-10T16:45:49Z 2018-01-10T16:45:49Z Troy MacDonald http://m.getsatisfaction.com/people/8849379 https://www.gravatar.com/avatar/820e6ab3e84043726fde188e44324447?d=identicon&s=55&r=PG troy_macdonald_446ms2t0se6jv Ran the Spectre and Meltdown detection tool on one of our switches running 3.4.2 on a Edgecore 4610-54T with ARM71 processor, here are the results:<br /><br />Spectre and Meltdown mitigation detection tool v0.23<br /><br />Checking for vulnerabilities against live running kernel Linux 4.1.0-cl-6-iproc #1 SMP Cumulus 4.1.33-1+cl3u9 (2017-08-11) armv7l<br /><br />CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'<br />* Checking count of LFENCE opcodes in kernel:&nbsp; UNKNOWN&nbsp; (missing 'readelf' tool, please install it, usually it's in the 'binutils' package)<br />&gt; STATUS:&nbsp; UNKNOWN&nbsp; (impossible to check )<br /><br />CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'<br />* Mitigation 1<br />*&nbsp; &nbsp;Hardware (CPU microcode) support for mitigation:&nbsp; UNKNOWN&nbsp; (couldn't read /dev/cpu/0/msr, is msr support enabled in your kernel?)<br />*&nbsp; &nbsp;Kernel support for IBRS:&nbsp; NO<br />*&nbsp; &nbsp;IBRS enabled for Kernel space:&nbsp; NO<br />*&nbsp; &nbsp;IBRS enabled for User space:&nbsp; NO<br />* Mitigation 2<br />*&nbsp; &nbsp;Kernel compiled with retpoline option:&nbsp; NO<br />*&nbsp; &nbsp;Kernel compiled with a retpoline-aware compiler:&nbsp; NO<br />&gt; STATUS:&nbsp; VULNERABLE&nbsp; (IBRS hardware + kernel support OR kernel with retpoline are needed to mitigate the vulnerability)<br /><br />CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3'<br />* Kernel supports Page Table Isolation (PTI):&nbsp; NO<br />* PTI enabled and active:&nbsp; NO<br />&gt; STATUS:&nbsp; NOT VULNERABLE&nbsp; (your CPU vendor reported your CPU model as not vulnerable)<br /><br />Any plans for mitigation?

The design goal here is to provide L2 extension across&nbsp;datacenters for VM mobility (DCI). A secondary goal is to provide local egress from VNIs to local gateways egressing the fabric.&nbsp;<br /><br />I am fairly certain that this can be accomplished with Cisco ACI and the multi-site topology model, which leads me to believe that it is also possible with Cumulus.&nbsp;<br /><br />I realize&nbsp;this is a very oversimplified question that requires a complex answer.

Extending Layer 3 down to the hosts by running a <br /> routing suite such as Quagga makes it possible to oversubscribe servers <br /> to an arbitrarily high number of top of rack switches and again to the <br /> aggregation layer.<br /><br /> Docker is a software delivery system built <br /> around a technology called "containers", which are very lightweight <br /> alternative to virtual machines. Docker makes it possible to deliver <br /> software like the Cumulus Linux version of Quagga to servers in a <br /> cross-platform way. This demo shows how to install and configure a fully<br /> layer 3 network with Quagga running on the hosts using Ansible.<br /><br /> <br /><br /> <a href="https://github.com/cumulusnetworks/cldemo-docker-quagga" rel="nofollow">https://github.com/cumulusnetworks/cldemo-docker-quagga</a> question 1 2 2 comment http://m.getsatisfaction.com/topics/7652396 7652396 Cumulus VX VXLAN routing 2017-12-22T18:04:27Z 2017-12-21T11:50:14Z Anton Lopatin http://m.getsatisfaction.com/people/9447017 https://www.gravatar.com/avatar/b4bf1e72209e603e7284e1f52ee215a1?d=identicon&s=55&r=PG anton_lopatin Does Cumulus VX support VXLAN routing?
