ntfs support
by Richmond 01 Feb '20

01 Feb '20

I should think this is quite a basic question but what I have tried so far hasn't worked. I have centos altarch 7 and I want to mount an ntfs volume. (I am beginning to suspect it is not available for 32 bit so I will need to get the source and compile?) These commands I have tried: yum --enablerepo=extras install epel-release yum --enablerepo=extras yum install epel-release I have enabled extras, but I don't know what epel-release is or how to enable it. yum repolist enabled Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.coreix.net * extras: mirrors.coreix.net * updates: mirrors.coreix.net repo id repo name status base/7/i386 CentOS-7 - Base 7,625 extras/7/i386 CentOS-7 - Extras 257 updates/7/i386 CentOS-7 - Updates 791 repolist: 8,673 yum search ntfs Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.coreix.net * extras: mirrors.coreix.net * updates: mirrors.coreix.net Warning: No matches found for: ntfs No matches found

Centos 7: setting DSCP values on bonding interfaces?
by hw 01 Feb '20

01 Feb '20

Hi, is it possible to set DSCP values on bonding interfaces? Packets from asterisk do not have their DSCP values set, so apparently it is not setting them despite it is set up for it, and it seems to be using libcap so it should be able to set them. I can see packets from phones having such values set when monitoring the traffic, so it's likely I would see packages from asterisk having values set if they were set. Perhaps asterisk can not set the values because a bonding interface is being used. Or there is something with Centos 7 that prevents setting the values?

system-config-network centos altarch
by Richmond 31 Jan '20

31 Jan '20

Hi I have just installed centos 7 altarch on a 32 bit computer. I selected the minimal system install. I see that when I search with yum there is no command system-config-network, i.e. yum search system-config-network Does this command (system-config-network) still exist? Would I expect it to be in the repository even though I did a minimum install? Although I do not have X, I can run some X applications by using ssh -Y from another computer, although messing with the network settings could be tricky...

CentOS 8 on USB disk
by Jerry Geis 31 Jan '20

31 Jan '20

I did the dd if=CentOS-8.1.1911-x86_64-dvd1.iso of=/dev/sdd to a 16G USB disk then tried to use it on an install. The installer said invalid install media. Any way to verify if the "write" to disk was good ? I got no errors on the dd. I did re-download the iso and did a diff and there was no diff. So I think my iso is OK. Jerry

Centos 8 on Macbook
by david 30 Jan '20

30 Jan '20

Folks I am trying to install Centos 8.1 on a MacBook Pro. I have a bootable USB stick with centos-8.1-boot (which I think is the equivalent of a netinstall), and it boots. However, when I select the storage option, and choose to make more space on the SSD, go through the confirming dialogs, the installer complains that it was unable to save the information to the disk. A similar attempt using Centos-7 netinstall successfully rewrites the SSD. This failure also occurs when I boot the Centos-8.1-dvd. Is there something else I should be doing? Thanks David

Centos 7: UPD packet checksum verification?
by hw 30 Jan '20

30 Jan '20

Hi, what does Centos 7 do with UPD packets having invalid checksums? Are such packets inevitably dropped? Does a network card drop them when it does checksum verification in hardware even before the packets go anywhere? In general, if someone were to send me UPD packets with invalid checksums over the internet, how far would such packets get? In particular, how likely it is that SRTP packets sent over the internet over UPD could be damaged in such a way that the verification of the authentication tag fails when they arrive at the receiver, and how might such damage be caused?
