Diagnosing IPv6 routing
by Kenneth Porter 01 May '20

01 May '20

I just got 50 Mbps symmetric fiber from AT&T and it includes a /56 of IPv6 addresses, replacing a much slower ADSL line. I never tried to get IPv6 working on the old connection. I'm using CentOS 7 as a gateway and it's worked great for several versions for IPv4. I'm not seeing any IPv6 default route on the WAN interface. I suspect I'm not getting route announcements. I think I have all the IPv6 variables in ifcfg-em2 set right. But I do notice that the accept_ra file in proc for that interface has value 1, not 2. Changing it to 2 doesn't change anything, though. No route appears. While I wait for an answer to my trouble ticket, is there some way to verify that I'm not receiving any RA packets? Is there a way to force a solicitation for one? Is there a tcpdump invocation I can use to watch for them? Are there log messages that will tell me when an RA has been seen and added to the routing table or ignored?

INITRD_MODULES
by Jerry Geis 30 Apr '20

30 Apr '20

I am trying to take a CentOS 7 img and get hyperv to boot. First step. qemu-img convert "CentOS7.img" -O vhdx -o subformat=dynamic "CentOS7.vhdx" after adding new hyper-v I get dracut-timeout... So doing some searching it says add hv_vmbus hv_netvsc hv_storvsc to INITRD_MODULES. which doesnt really exist any more in CentOS 7. I did find /etc/dracut.conf and add_drivers... I uncommented the line for '#add_drivers += "" ' added the above modules and then ran: grub2-mkconfig -o /boot/grub2/grub.cfg Then redid the convert above... Hyper-V still gives me dracut-timeout errors. Thoughts ? Did I miss something ? Thanks Jerry

Tomcat or what on CentOS 8?
by Simon Matter 29 Apr '20

29 Apr '20

Hi, We're running some web apps on CentOS 6 on Tomcat 6 shipped by the distribution. As time goes by we'd like to move on to CentOS 8 and Tomcat 9 or whatever is appropriate. My question is, what do others use now that Tomcat is not shipped anymore with CentOS? Do you run some JBoss/WildFly instead or still running Tomcat? And, how do you install/manage those installations. Do you have RPM packaged versions or fiddle with tarballs? Since this is a quite standard setup for web apps I'm really wondering how everybody is doing it these days? Thanks, Simon

Checksums in Distribution Directories
by david 29 Apr '20

29 Apr '20

Folks While trying to automate a download of the ISO files, I ran into inconsistencies with the method of checksums. I was trying to use the checksum values to validate my download. At least in one mirror (mirrors.sonic.net): Centos 7 uses a file called sha256sum.txt containing: 087a5743dc6fd6706d9b961b8147423ddc029451b938364c760d75440eb7be14 CentOS-7-x86_64-DVD-2003.iso 4120aff542c2f9a30bcf90d4d79e39511e5d9eabdf202566a94ff24ea7f0974c CentOS-7-x86_64-Everything-2003.iso 659691c28a0e672558b003d223f83938f254b39875ee7559d1a4a14c79173193 CentOS-7-x86_64-Minimal-2003.iso 101bc813d2af9ccf534d112cbe8670e6d900425b297d1a4d2529c5ad5f226372 CentOS-7-x86_64-NetInstall-2003.iso 3febddab1498f940e3127f2f5e1056d6fef57fcd559d5b70ff1bfa55a444f176 CentOS-7-x86_64-LiveGNOME-2003.iso 92be566a5b1d2aa62acf2e4ab01ba91420e7170cdb21e2e190dd1dafcb6a8c94 CentOS-7-x86_64-LiveKDE-2003.iso Centos 8 uses a file called CHECKSUM containing: # CentOS-8.1.1911-x86_64-boot.iso: 625999872 bytes SHA256 (CentOS-8.1.1911-x86_64-boot.iso) = 7fea13202bf2f26989df4175aace8fdc16e1137f7961c33512cbfad844008948 # CentOS-8.1.1911-x86_64-dvd1.iso: 7554990080 bytes SHA256 (CentOS-8.1.1911-x86_64-dvd1.iso) = 3ee3f4ea1538e026fff763e2b284a6f20b259d91d1ad5688f5783a67d279423b While these are fairly easy to understand as a human, a script is burdened with the job of guessing the file name of the checksum file, and then decoding the format. I don't know if this method is used on all mirrors. Would it be too much to ask that there be one format across the distributions. I suspect that SHA256 is going to be an acceptable digest for a few years. David

Network Interfaces Issue
by Jared Jacob 28 Apr '20

28 Apr '20

I have two network interfaces configured on a server. I would like both of them to be configured to start on boot, but when I enable the second interface to start on boot I do not have access to the first network interface. The second interface is a private network and does not allow any communication our or in from any other interfaces. I can start the server with the first network interface being the only one enabled to start at boot and go in and activate the second interface which allows communication on both interfaces, but when they are both enabled to start on boot only the private interface can communicate. I am running Centos 7.7. Thanks in advance for any assistance you can provide. Jared Jacob

Understanding modularity
by Simon Matter 28 Apr '20

28 Apr '20

Hi, I've read the Fedora modularity docs but am still missing the big picture somehow. Hope someone can clarify things for me. What I'm most wondering: does modularity have any influence on the RPM packages at all. I mean, is there anything inside a RPM package which says it belongs to a module or it has a special function in a module? >From what I understand the RPMs are just completely normal packages and only YUM/DNF knows from some metadata that an RPM belongs to a module. Is that corrent? Thanks for any insights, Simon

Weird problem with my app and blocked ports
by david allan finch 27 Apr '20

27 Apr '20

Hi, Not sure where to look for my issue. I hope someone can point me in the correct place. I have been working on a bespoke server package for more than twenty years. It was originally developed on Solaris (Unix), was ported to windows and now ported to Linux for the last five years. This system is in live production under heavy usage everyday. The servers are all written in C++ and use a version of encoded ONC RPC (without bind) to communicate server to server and java for the client displays. Since about six months ago, I have been experiencing a weird issue with the sockets on my test system. My dev env is on CentsOS 7.7 running on Virtualbox 6 on a Windows 10 machine. The VM has bridge networks interface to my lan using a static IP. Our servers talk on the interface on Virtualbox to other servers possibly on other hosts via my real network. All works well until I do a massive relability and soak test of one of our servers. I send a series of large data message every 15 second or so to one of our servers (say Y), expecting that I might see a lockup and bugs to fix etc in that server Y. But instead of Y server failing what I see is the well know port that our system uses (ie 2323) for name lookup requests, block and I then see timouts of on that socket (this is a different server say Z). All the others servers (A..Y) get timeouts communicating to Z from then on. This effect I don't see on other OSs with similar tests. If I systemctl stop our service and then restart the servers A-Y start but continue to fail with timeouts to Z. Reboot does the same. I have change the well know port to 23232 and it still fails. I have run the servers in the systemctl as a new user and it still fails. As a mad idea I change the interface so the servers talk on the virtual box internal network and the system returns to operation. Also if I run the servers manually on the command line as my user account they work. It kind of looks like a firewall/anti-virus/tojan block rule on our well known port 2323 or Z server. As far as I can see the CentOS firewall is not running. The Norton firewall on my PC does not seam to have an rules or warning about my virtualbox ips or ports. Our servers don't cache any ip data. The first time this happened I was too busy to look at it and just restored the VM from a backup. It then happened a second time a month ago and spend a day looking at the issue found nothing and restored from backup again, putting it down to the centos security update I have just done earlier that day. It happen for a third time on Friday (24th). This time I have done no updates since the last restore so I can be sure its not a centos update. I checked again could find nothing wrong, did all the updates and still nothing worked. Investigated all the firewall and interfaces and it works. I need the system to work on the external bridge network interface and I can't think of anything else todo. The socket error messages are just Timeout, there is nothing in dmesg, or journal that suggests anything. I am now a complete lost to what is happening and why. Regards David Finch
