At your suggestion, the command became iptables -I INPUT -p tcp --dport 22 -i enp3s0 -s 10.0.0.0/24 -j DROP where enp3s0 is the internal NIC with address 10.0.0.1. I'm assuming that your advice about LAN represents the internal network because on most routers, it is, and WAN is the internet connection. And ssh worked :-( unfortunately I know that many ISPs block outgoing port 25, so I know this is do-able. David

So simple that it doesn't seem like it could make much of a difference, but it does.

Upgrade to 8.2 from 7.8

So now that 8 is out - is it still "frowned" upon to do that in place update ? Is that not a good / valid solution ? Thanks, Jerry

Simple scan in CentOS 7
by H 16 Jun '20

16 Jun '20

I just installed C7 on a new computer and despite Simple Scan being installed as part of C7, I have not been able to get it to recognize my Canon scanner connected to a USB port. I did have it running on another computer with C7 so there should not be any inherent issues. On a lark I installed gscan2pdf and sane-backends-drivers-scanners and sane-find-scanner found it: found USB scanner (vendor=0x04a9 [Canon], product=0x1908 [CanoScan]) at libusb:001:010 I perused my notes for the old computer but did not see I installed any additional software to get it going but I might be wrong. What have I missed? Thank you.

iwlwifi problem after Centos 8.2 update
by Georgios 16 Jun '20

16 Jun '20

Hi! I get high cpu usage on my laptop (yes im running Centos on my laptop) after my last update. At the beginning i though it was libvrtd but after stopping it gnome monitor keep showing high cpu usage although i couldnt find the app that was responsible for it with the top command. I searched my log files and I saw alot of iwlwifi message. I had to turn off wifi in order to stop high cpu usage. Any ideas how to solve it? Thanks in advance! dmesg command gives me the following output: 649.668600] RSP: 002b:00007fffaa691d60 EFLAGS: 00000293 ORIG_RAX: 000000000000002e [ 649.668602] RAX: ffffffffffffffda RBX: 000000000000000e RCX: 00007f21aecdeb07 [ 649.668603] RDX: 0000000000000000 RSI: 00007fffaa691db0 RDI: 000000000000000e [ 649.668604] RBP: 00007fffaa691db0 R08: 0000000000000000 R09: 0000000000000000 [ 649.668605] R10: 0000000000000012 R11: 0000000000000293 R12: 0000000000000000 [ 649.668605] R13: 0000000000000000 R14: 00007fffaa691f68 R15: 00007fffaa691f5c [ 649.756674] iwlwifi 0000:00:14.3: Found debug destination: EXTERNAL_DRAM [ 649.756676] iwlwifi 0000:00:14.3: Found debug configuration: 0 [ 649.757247] iwlwifi 0000:00:14.3: loaded firmware version 46.6bf1df06.0 op_mode iwlmvm [ 649.757275] iwlwifi 0000:00:14.3: Detected Intel(R) Dual Band Wireless AC 9462, REV=0x318 [ 649.765604] iwlwifi 0000:00:14.3: Applying debug destination EXTERNAL_DRAM [ 649.765843] iwlwifi 0000:00:14.3: Allocated 0x00400000 bytes for firmware monitor.

Today's Topics: 1. Release for CentOS Linux 8 (2004) (Brian Stinson) ---------------------------------------------------------------------- Message: 1 Date: Mon, 15 Jun 2020 11:29:32 -0500 From: Brian Stinson <bstinson(a)centosproject.org> To: centos-announce(a)centos.org Subject: [CentOS-announce] Release for CentOS Linux 8 (2004) Message-ID: <1491307c-4a76-1bc2-7375-9c85cdff3214(a)centosproject.org> Content-Type: text/plain; charset=utf-8 Release for CentOS Linux 8 (2004) We are pleased to announce the general availability of CentOS Linux 8. Effectively immediately, this is the current release for CentOS Linux 8 and is tagged as 2004, derived from Red Hat Enterprise Linux 8.2 Source Code. As always, read through the Release Notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS8.2004? - these notes contain important information about the release and details about some of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from the users. ---------- Updates, Sources, and DebugInfos Updates released since the upstream release are all posted, across all architectures. We strongly recommend every user apply all updates, including the content released today, on your existing CentOS Linux 8 machine by just running 'dnf update'. As with all CentOS Linux 8 components, this release was built from sources hosted at git.centos.org. Sources will be available from vault.centos.org in their own dedicated directories to match the corresponding binary RPMs. Since there is far less traffic to the CentOS source RPMs compared with the binary RPMs, we are not putting this content on the main mirror network. If users wish to mirror this content they can do so using the reposync command available in the yum/dnf-utils package. All CentOS source RPMs are signed with the same key used to sign their binary counterparts. Developers and end users looking at inspecting and contributing patches to the CentOS Linux distro will find the code hosted at git.centos.org far simpler to work against. Details on how to best consume those are documented along with a quick start at : http://wiki.centos.org/Sources Debuginfo packages have been signed and pushed. Yum configs shipped in the new release file will have all the context required for debuginfo to be available on every CentOS Linux install. This release supersedes all previously released content for CentOS Linux 8, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the Release Notes. Note that older content, obsoleted by newer versions of the same applications are trim'd off from repos like extras/ and centosplus/ ---------- Download We produced the following installer images for CentOS Linux 8 # CentOS-8.2.2004-x86_64-minimal.iso: 1718616064 bytes SHA256 (CentOS-8.2.2004-x86_64-minimal.iso) = 47ab14778c823acae2ee6d365d76a9aed3f95bb8d0add23a06536b58bb5293c0 # CentOS-8.2.2004-x86_64-boot.iso: 654311424 bytes SHA256 (CentOS-8.2.2004-x86_64-boot.iso) = c67876a5602faa17f68b40ccf2628799b87454aa67700f0f57eec15c6ccdd98c # CentOS-8.2.2004-x86_64-dvd1.iso: 8231321600 bytes SHA256 (CentOS-8.2.2004-x86_64-dvd1.iso) = c87a2d81d67bbaeaf646aea5bedd70990078ec252fc52f5a7d65ff609871e255 # CentOS-8.2.2004-aarch64-minimal.iso: 1410226176 bytes SHA256 (CentOS-8.2.2004-aarch64-minimal.iso) = 621d08902bfd7ca8437cd536b86631c87ddc3e36a530abc77011d230401eb158 # CentOS-8.2.2004-aarch64-boot.iso: 579823616 bytes SHA256 (CentOS-8.2.2004-aarch64-boot.iso) = 76a9a5f84ac9581fee079d7154bf68f72661c9d941e9ab3143bccc760c23eecc # CentOS-8.2.2004-aarch64-dvd1.iso: 5988872192 bytes SHA256 (CentOS-8.2.2004-aarch64-dvd1.iso) = 9d2f066edfc3820fc9e4c6d52f01489a3ed57515cf608773e2b8a04f1903c838 # CentOS-8.2.2004-ppc64le-minimal.iso: 1493422080 bytes SHA256 (CentOS-8.2.2004-ppc64le-minimal.iso) = 1d6802ce5581bd6ae22d13e491dfad65b7a32166f1484e8d6c532cd4cd7e18db # CentOS-8.2.2004-ppc64le-boot.iso: 628408320 bytes SHA256 (CentOS-8.2.2004-ppc64le-boot.iso) = a039bc592e416b97914b6c99cc8cb070d6b35742dbcb7b6eccff55291659c664 # CentOS-8.2.2004-ppc64le-dvd1.iso: 7080738816 bytes SHA256 (CentOS-8.2.2004-ppc64le-dvd1.iso) = 1a94eff60fd016ea8efb1d592eda85f0b5edde2ff2ad4c77db546ab90392421e Information for the torrent files and sums are available at http://mirror.centos.org/centos/8/isos/ -------- Additional Images Vagrant and Generic Cloud images are available at: http://cloud.centos.org/centos/8/ Amazon Machine Images for Amazon Web Services are published by ID into a number of regions.

The best place to start for new users is at http://wiki.centos.org/GettingHelp We are also on social media, you can find the project: on Twitter at? :http://twitter.com/CentOSProject on Facebook at :https://www.facebook.com/groups/centosproject/ on LinkedIn at :https://www.linkedin.com/groups/22405 And you will find the core team and a majority of the contributors on irc, on freenode.net in #centos ; talking about the finer points of distribution engineering and platform enablement. ---------- Contributors This release was made possible due to the hard work of many people, foremost on that list are the Red Hat Engineers for producing a great distribution and the CentOS QA team, without them CentOS Linux would look very different. Many of the team went further and beyond expectations to bring this release to you, and I would like to thank everyone for their help. We are also looking for people to get involved with the QA process in CentOS, if you would like to join this please introduce yourself on the centos-devel list (http://lists.centos.org/mailman/listinfo/centos-devel? ). Finally, please join me in thanking the donors who all make this possible for us. Enjoy the fresh new release!

smb protocol version
by Christopher Wensink 16 Jun '20

16 Jun '20

I have a handful of Linux Servers, running Centos 6.10, and 6.8 with the main host running openvz w/ Centos 6.10 as the main OS. Two of the guests are running samba, sharing directories out to windows clients. I'm in the process of migrating servers over to vmware, using Centos 7.8. How can I determine what smb protocol version is being used in the shares for each server? I don't see the protocol specified anywhere in smb.conf? Chris

Re: [CentOS] C8 install problems SOLVED
by ejm 16 Jun '20

I burned a total of 7.55Gb from an ISO image to a dual-layer HP DVD+R disc. I got a bootable USB stick containing 8.1 and it's 7.65 Gb so apparently my ISO image file is messed up. I was able to install C8 just fine from the USB stick, so marking this as solved. Thanks, --Ed

/etc/networks file
by Jay Hart 15 Jun '20

15 Jun '20

I am having some network connectivity issues that manifest itself through ping, wget, dnf, etc. The symptoms are intermittent ability to ping, was wget, or connect to repositories. Where this inquiry is going is: If your internal network is using 192.168.1 or 10..50.10, what should be in /etc/networks. My current file contains: default 0.0.0.0 loopback 127.0.0.0 link-local 169.254.0.0 And I'm pretty sure this is the default OS installed contents. I don't think this is related to my connectivity issue, just curious about what this file does. My old server (which is working just fine) has the same content in its /etc/networks file so not configuring this does not seem to matter one way or the other. If one were using 192.168.1.x network , assume 'default' should be 192.168.1.0. 'Link-local' should match??? Thanks, Jay

halt versus shutdown
by Leon Fauster 15 Jun '20

15 Jun '20

Working with different OSs can be quite challenging (mentally :-)). I wonder why the command "halt" has not same result between EL6 and EL8. To shutdown the vm or workstation in EL8 i must use "shutdown now". Who mandates this behavior in terms of configuration file? -- Leon
