After a recent large update, firewalld's status contains many lines of the form: WARNING: COMMAND_FAILED: '/usr/sbin/iptables... Checking iptables.service status shows it to be masked. I realize that firewalld uses iptables, but should it be enabled and started as a service? Jon -- Jon H. LaBadie jcu at labadie.us 11226 South Shore Rd. (703) 787-0688 (H)

I'm running Centos 7.8.2003, with firewalld. I was getting huge numbers of ssh attempts per day from a few specific ip blocks. The offenders are 45.0.0.0/24, 49.0.0.0/24, 51.0.0.0/24, 111.0.0.0/24 and 118.0.0.0/24, and they amounted to a multiple thousands of attempts per day. I installed and configured fail2ban, but still saw a lot of attempts in the logs, and the ipset created was

I need to schedule a process/program every hour on the hour between 9am and 4pm on the 2nd through the 9th of each month except on Saturday and Sunday.? So, I tried this entry: 0 9-16 2-9 * 1-5 ./myprog.sh Unfortunately it runs outside of the 2nd through the 9th and still runs on Sat. through Sun. Is there a way to do this (outside the program itself)? -Frank

This is odd, and annoying. CentOS 6, current. Here's my awk script: { room = substr($0, 48, 10); arr[$2,room,$1] = $0; } END { for ( i in arr ) { for ( j in arr[i] ) { for ( k in arr[i][j] ) { print arr[i][j][k]; } } } } And when I run it, it complains awk -f awksort proplist7 awk: awksort:7: for ( j in arr[i] ) { awk: awksort:7:

Hello there, while bash completion was working great to me in CentOS6, since I'm using C7 I spend my day stuck on completion not working the way it should. The bad situations I'm facing are: - it doesn't expand *foo whereas there are *foo-named files in current dir, for instance: # rm *foo will show nothing whereas there's a file barfoo in curdir. - completion takes 10

I don't believe this is accurate. ro and rw are mutually exclusive, but there is no "w" option. (Which doesn't help the OP, unfortunately, but at least he knows.) For the

After the large update from 7.2 -> 7.3 there is one major problem, the amanda backup packages. Strange situation, the host is the amanda server is working fine at backing up all my remote clients. But it has an error backing up itself. The amanda packages did not change version (3.3.3) and I've done no configuration change. I'm not looking for help debugging this at the moment.

Hello, I have a CentOS VM with only one disk on a Xenserver. The disk has 2 partitions: /dev/xvda1 -> /boot /dev/xvda2 -> a physical volume for LVM I added 5GB to this disk via Xencenter to extend /dev/xvda2. Usually I just have to do "pvresize /dev/xvda" to have the additional space added to the disk. But for some reason it does not work for this disk. [root ~]# pvresize
