deprecations leading up to C8
by Fred Smith 23 Sep '19

23 Sep '19

Was reading the long list of things being deprecated in the RHEL 8 release notes t'other day, and saw my old friend sendmail on the list. I've stuck by her because I've learned how she likes to be stroked to get the best out of her, and quail at the thought of taking on a new MTA and having to learn it all all over again. But I guess I'm going to have to, soon or late, probably sooner than later. :( Can anyone point me to resources specifically for helping us ignorant folk in converting all the arcan-ity in sendmail.mc into something equivalent for Postfix? Thanks in advancce!

7.7.1908, interface bonding, and default route
by Carlos A. Carnero Delgado 20 Sep '19

20 Sep '19

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24 GATEWAY=10.3.20.1 DNS1=10.3.2.8 BONDING_MASTER=yes BONDING_OPTS="mode=802.3ad xmit_hash_policy=layer2 miimon=100" The slaves (two of them) are configured like TYPE=Ethernet BOOTPROTO=none NAME=bond0-slave0 DEVICE=em3 ONBOOT=yes MASTER=bond0 SLAVE=yes After booting, the routing table is 10.3.20.0/24 dev bond0 proto kernel scope link src 10.3.20.131 metric 300 with no default route configured (manually adding it will work, of course.) This machine worked perfectly before, and it did during previous upgrades and reboots. Has anyone ever had this problem before? Thanks, Carlos.

running init disconnects ssh session
by Stephen Berg (Code 7309) 20 Sep '19

20 Sep '19

Noticing a new behavior lately. Logged in via sshd and ssh keys as root to a remote system. When changing runlevels between multi-user or graphical the ssh session is disconnected. It's not a big deal but annoying if I have other tasks to do on that particular system. I've tried logging in as normal user, su to root and it still disconnects the ssh session upon either an "init 3" or "systemctl isolate multi-user.target" command. -- Stephen Berg, IT Specialist, Ocean Sciences Division, Code 7309 Naval Research Laboratory W: (228) 688-5738 <- (Preferred contact) DSN: (312) 823-5738 C: (228) 365-0162

selinux reports
by Fred Smith 19 Sep '19

19 Sep '19

Hi all! I keep getting reports from selinux, like below, and I have no clue what the app is it's talking about, nor how do figure out if it should be allowed access or not. Anyone got any advice to offer? It says: The source process: /usr/sbin/xtables-multi attempted this access: open on this file: /run/xtables.lock Having no clue what xtables-multi is, or why or even if it should be able to open that file, I am at a loss: should I take action to enable it, or not? Thanks in advance!

UEFI booting
by Jerry Geis 19 Sep '19

19 Sep '19

I installed my first UEFI disk yesterday. Seemed to go fine. CentOS 7.6 x86_64 I then took that disk "out" of that machine and put it another machine - it seems to not even boot. I put the original disk back in that machine and it boots fine. I put the UEFI disk back in the machine I built it on and it works fine. They are similar machines either and i3 and i7. Shouldn't that work? Build a UEFI disk on machine A - move it to machine B? Thanks Jerry

Postfix vs. Thunderbird on Mac OS
by Nicolas Kovacs 19 Sep '19

19 Sep '19

Hi, I'm running our local school's mail server on CentOS 7, Postfix and Dovecot. We get quite a lot of spam, so I have the following sender restrictions in my /etc/postfix/main.cf: --8<------------------------------------------------------ # Restrictions SMTP smtpd_helo_restrictions = reject_unknown_helo_hostname smtpd_sender_restrictions = reject_unknown_sender_domain, check_sender_access hash:/etc/postfix/sender_access smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_rbl_client zen.spamhaus.org, reject_rhsbl_reverse_client dbl.spamhaus.org, reject_rhsbl_helo dbl.spamhaus.org, reject_rhsbl_sender dbl.spamhaus.org smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_data_restrictions = reject_unauth_pipelining --8<------------------------------------------------------ Most folks are using Thunderbird on Linux, and everything works perfectly. One single user has a MacBook Air with Thunderbird on Mac OS Mojave, and her outgoing mails are rejected with the following error message in /var/log/maillog on the server: --8<------------------------------------------------------ Sep 16 14:22:32 sd-48011 postfix/smtps/smtpd[14434]: NOQUEUE: reject: RCPT from villa.figaret.pck.nerim.net[62.212.106.47]: 450 4.7.1 <Air-de-bea.scholae.lan>: Helo command rejected: Host not found; from=<xxxxx.yyyyyyyy(a)scholae.fr> to=<info(a)microlinux.fr> proto=ESMTP helo=<Air-de-bea.scholae.lan> --8<------------------------------------------------------ As far as I understand, it has to do with this MacBook's host configuration. Any suggestions?

conflicts in updating to CR repo
by Fred Smith 19 Sep '19

19 Sep '19

Note, first of all I haven't actually updated, I'm just running "yum update" to see what conflicts, if any, I get so I can be prepared when the final 7.7 release happens. I've traditionally used the nvidia packages from elrepo, but recently enabled rpmfusion (back when I started using 7.x, I disabled rpmfusion because it took them a looooong time to get a EL7 repository up). I use the priority plugin in yum, and have elrepo at priority 50 and rpmfusion at priority 60, so the elrepo nvidia packages should "win", but yum seems to be confused about which packages to use. So now when doing yum update (with CR enabled) I get this long list of dependency issues regarding the nvidia packages. I don't see any reason to switch to the rpmfusion packages, elrepo seems to do a good job of packaging and keeping them up to date: --> Processing Dependency: xorg-x11-drv-nvidia-390xx-libs(x86-64) = 3:390.129-1.el7 for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Processing Dependency: nvidia-settings-390xx(x86-64) = 390.129 for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Processing Dependency: libnvidia-tls.so.390.129()(64bit) for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Processing Dependency: libnvidia-glcore.so.390.129()(64bit) for package: 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 --> Running transaction check ---> Package nvidia-settings-390xx.x86_64 0:390.129-1.el7 will be installed ---> Package xorg-x11-drv-nvidia-390xx-libs.x86_64 3:390.129-1.el7 will be installed --> Processing Conflict: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 conflicts xorg-x11-drv-nvidia-390xx Removing kmod-nvidia.x86_64 0:430.50-1.el7_7.elrepo - u due to obsoletes from kmod-nvidia-390xx.x86_64 3:390.129-3.el7 - u --> Restarting Dependency Resolution with new changes. --> Running transaction check ---> Package kmod-nvidia.x86_64 0:430.50-1.el7_7.elrepo will be an update --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 ---> Package nvidia-x11-drv.x86_64 0:430.40-1.el7_6.elrepo will be updated ---> Package nvidia-x11-drv.x86_64 0:430.40-1.el7_6.elrepo will be updated --> Finished Dependency Resolution --> Running transaction check ---> Package kernel.x86_64 0:3.10.0-957.21.2.el7 will be erased ---> Package kernel-devel.x86_64 0:3.10.0-957.21.2.el7 will be erased ---> Package kmod-nvidia.x86_64 0:430.50-1.el7_7.elrepo will be an update --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 --> Processing Dependency: nvidia-kmod = 430.50 for package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 --> Processing Conflict: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 conflicts xorg-x11-drv-nvidia-390xx --> Finished Dependency Resolution Error: nvidia-x11-drv conflicts with 3:xorg-x11-drv-nvidia-390xx-390.129-1.el7.x86_64 Error: Package: nvidia-x11-drv-430.50-1.el7_7.elrepo.x86_64 (elrepo) Requires: nvidia-kmod = 430.50 Removing: kmod-nvidia-430.40-1.el7_6.elrepo.x86_64 (@elrepo) nvidia-kmod = 430.40-1.el7_6.elrepo Obsoleted By: 3:kmod-nvidia-390xx-390.129-3.el7.x86_64 (rpmfusion-nonfree-updates) Not found Updated By: kmod-nvidia-430.50-1.el7_7.elrepo.x86_64 (elrepo) nvidia-kmod = 430.50-1.el7_7.elrepo Available: 3:akmod-nvidia-430.40-2.el7.x86_64 (rpmfusion-nonfree-updates) nvidia-kmod = 3:430.40-2.el7 Available: kmod-nvidia-430.14-1.el7_6.elrepo.x86_64 (elrepo) nvidia-kmod = 430.14-1.el7_6.elrepo Available: kmod-nvidia-430.26-1.el7_6.elrepo.x86_64 (elrepo) nvidia-kmod = 430.26-1.el7_6.elrepo Available: kmod-nvidia-430.34-1.el7_6.elrepo.x86_64 (elrepo) nvidia-kmod = 430.34-1.el7_6.elrepo Available: kmod-nvidia-430.40-2.el7_7.elrepo.x86_64 (elrepo) nvidia-kmod = 430.40-2.el7_7.elrepo Available: 3:kmod-nvidia-430.40-2.el7.x86_64 (rpmfusion-nonfree-updates) nvidia-kmod = 3:430.40-2.el7 Available: 3:kmod-nvidia-3.10.0-1062.el7.x86_64-430.40-2.el7.x86_64 (rpmfusion-nonfree-updates) nvidia-kmod = 3:430.40-2.el7 You could try using --skip-broken to work around the problem Thanks in advance for advice!
