Bootable USB keys : which brand ?
by Nicolas Kovacs 19 Jun '20

19 Jun '20

Hi, In my daily work I'm mainly using USB keys for work : one with CentOS 7, one with OpenSUSE Leap 15.1, one with Slax Live for data recovery purposes, one with Ghost4Linux and one with FreeDOS which I use for flashing the odd BIOS. Last week I bought a set of three flashy colored USB keys in a local shop. To my surprise, none of them seem to be able to boot anything. When I write a bootable image (CentOS, OpenSUSE, whatever) to any one of the USB keys, the USB key boot option doesn't show up on any one of my sandbox PCs. Looks like I just learnt the hard way that some USB keys can't be used for installation purposes. As far as I can tell, I need a set of 8 GB keys so the biggest image, the CentOS 8 ISO, can fit. Can you recommend a no-nonsense USB key brand which I can use to make a set of USB installation keys ?

Apache (httpd) fails to start at boot - Centos 8.1
by Jay Hart 19 Jun '20

19 Jun '20

If I do 'systemctl start httpd', apache will start right up. But during boot, it doesn't and I get the resulting errors below. Jun 15 21:17:28 dream httpd[1534]: (99)Cannot assign requested address: AH00072: make_sock: could not bind to address 10.20.30.11:80 Jun 15 21:17:28 dream httpd[1534]: no listening sockets available, shutting down Jun 15 21:17:28 dream httpd[1534]: AH00015: Unable to open logs Jun 15 21:17:29 dream systemd[1]: httpd.service: Main process exited, code=exited, status=1/FAILURE Jun 15 21:17:29 dream systemd[1]: httpd.service: Failed with result 'exit-code'. the box's ip address is 10.20.30.11, and I am trying to get http (80), and https (443) going. Firewall is turned on. The listen parameter in httpd.conf is 10.20.30.11:80 The log files in /var/log/httpd are all owned by root. Httpd runs as user 'apache'. Google searches have not returned anything that looks remotely promising. Got any suggestions? Thanks in advance, Jay

Can't access Squirrelmail on Centos 8
by Jay Hart 19 Jun '20

19 Jun '20

Good evening, I have not able able to run the http://ip-addr/src/configtest.php script, nor access Squirrelmail. Looking for suggestions on what I might have missed. When I try either http://ip-... or https://ip-..., I get the following reply Forbidden You don't have permission to access /webmail/src/configtest.php on this server. I got squirrelmail installed in /usr/share/squirrelmail and 'configured' to work (using ./conf.pl). This setup below is about the same setup on my Centos 6 box. I'm thinking my issue is more Apache configuration related than Squirrelmail. **Apache is running with no issues** Below are some of my settings in /etc/httpd/conf/httpd.conf Apache ServerRoot is /etc/httpd Apache DocumentRoot is /www Further parameters within httpd.conf include: # # Relax access to content within /var/www. # <Directory "/www"> AllowOverride None # Allow open access: Require all granted </Directory> # Further relax access to the default document root: <Directory "/www"> Options Indexes FollowSymLinks AllowOverride None # # Controls who can get stuff from this server. # Require all granted </Directory> In /etc/httpd/conf.modules.d I created a file called 16-squirrelmail.conf That file contains the following information: # SquirrelMail is a webmail package written in PHP. # Alias /webmail /usr/share/squirrelmail <Directory "/usr/share/squirrelmail/plugins/squirrelspell/modules"> #<Directory "/usr/share/squirrelmail"> AllowOverride None Require all denied </Directory> # this section makes squirrelmail use https connections only, for this you # need to have mod_ssl installed. If you want to use unsecure http # connections, just remove this section: #6-12-2020 commented out next five lines to test sqmail in http mode only <Directory /usr/share/squirrelmail> RewriteEngine on RewriteCond %{HTTPS} !=on RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} </Directory> Any suggestions???? Thanks, Jay

CentOS 8 gvs question
by Jerry Geis 18 Jun '20

18 Jun '20

I am getting a timeout on running totem .... searching led me to think its gvs related.... Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.GoaVolumeMonitor: Timeout was reached (g-io-error-quark, 24) Then totem does start - but with like a 30 second delay. I ran this command and it says its inactive systemctl --user status gvfs-mtp-volume-monitor.service ● gvfs-mtp-volume-monitor.service - Virtual filesystem service - Media Transfer Protocol monitor Loaded: loaded (/usr/lib/systemd/user/gvfs-mtp-volume-monitor.service; static; vendor preset: enabled) Active: inactive (dead) What is the cause of my timeout ? Thanks, jerry

CentOS 8.2 corrupt pxeboot kernel
by isdtor 17 Jun '20

17 Jun '20

Attempting to PXE boot from the BaseOS/x86_64/kickstart/images/pxeboot/ files results in repeating messages Invalid or corrupt kernel image eventually changing to Could not find kernel image: centos8.2.x86_64/vmlinuz I downloaded the files again, from a different mirror, and they are all the same. Wiped the files and recreated /tftpboot/linux-install/centos8.2.x86_64/. No dice. First mirror 89251241a484010b98280ce00b3a3763 os/images/pxeboot/initrd.img 9261bb24add6bb4ff9ef6aaf348aaf35 os/images/pxeboot/vmlinuz Second mirror 89251241a484010b98280ce00b3a3763 os/images/pxeboot/initrd.img 89251241a484010b98280ce00b3a3763 kickstart/images/pxeboot/initrd.img 9261bb24add6bb4ff9ef6aaf348aaf35 os/images/pxeboot/vmlinuz 9261bb24add6bb4ff9ef6aaf348aaf35 kickstart/images/pxeboot/vmlinuz

Compile gnutls yo install samba-4.12.3
by Rommel Rodriguez Toirac 17 Jun '20

17 Jun '20

Hello all; Has anyone installed samba4 from sources (samba-4.12.3.tar.gz) on CentOS 7? I explain the problem: to install samba-4.12.3 you need to install a version equal to or greater than 3.4.7 of gnutls; this (gnutls) depends on nettle and gmp. I am trying to install gnutls-3.6.14; I already have gmp (gmp-6.2.0) and nettle (nettle-3.6) installed (compiled from sources), but gnutls doesn't want to install, it tells me "Libnettle 3.4.1 was not found" when I run the ./configure Nettle is installed in /usr/local/include/nettle (all .h) and in /usr/local/lib64/libnettle.s0.8.0 I created a symbolic link for /usr/lib64 from /usr/local/lib64/libnettle.s0.8.0 as libnettle.so and libnettle.so.8; I ran the gnutls ./configure again, but it keeps saying it can't find libnettle 3.4.1 How can I do? Has anyone got CentOS 7 and samba-4.12.3 installed and fixed this situation? -- Rommel Rodriguez Toirac rommelrt(a)nauta.cu

firewall help request
by david 17 Jun '20

17 Jun '20

Folks I'm struggling with my firewall settings, and would appreciate some help. I have a gateway machine (currently Centos 7 with IPV4 only) with two NICs. One is connected to the internet, the other to an internal network (10.0.0.0/24) of mixed hardware (windows7, android tablets, android phones, linux boxes) using NAT. I wish to block all outgoing connects to any external IP address on port 22 (ssh) originating from any internal machine except one (which has a known internal IP address). I've tried some commands using 'iptables' to accomplish this, but so far have failed. If anyone has a suggestion, I'd really appreciate it. In addition, a suitable version for 'firewalld' could be useful, as an upgrade to Centos 8 is in plan. Examples of what I've tried, and then tested. None of them stopped an outgoing SSH from an internal system. iptables -I INPUT -p tcp --dport 22 -s 10.0.0.0/24 -j DROP iptables -I INPUT -p tcp --dport 22 -s 10.0.0.0/24 -j DROP Much thanks David
