RPM perl requirements woes
Dear CentOS hive mind, I'm trying to package up a perl module into an RPM for easy deployment. I want it to be as self-contained as possible (to avoid version issues with perl modules in base or EPEL). So in my spec file, I'm doing: curl -L http://cpanmin.us | perl - App::cpanminus -L %{buildroot}/opt/zonemaster Zonemaster This way, cpanminus is installed first, and then it goes on to

Heh, okay, that's an easy explanation. I'll try to open a bug report in RedHat's bugzilla, and see if they give me any attention. Regards, Anand

Old and new package version numbers during RPM update
Hi CentOS folk, In an RPM post-install script, is it possible to know the previous version number, and the new version number of a package if it's an update? I need to know this, because for a certain package, if updating from version 1.x to 2.x, I need to run a program to convert the config file of the package from version 1.x format to version 2.x format. I've looked at SPEC file

tcpdump loses lots of packets
Hi folks, I've got a Dell R320 running CentOS 7, and a 10G NIC. I'm running a DNS server on it, for testing. As part of my testing, I'm attempting to capture all the DNS queries arriving on the server, using tcpdump. However, tcpdump's performance is abysmal, and it loses lots of the packets. Here's the output when I stop the capture: # tcpdump -nn -i p1p1 -w

kernel-lt from ELRepo vs. GRUB: define default boot kernel
Hi, After upgrading my workstation to CentOS 7.5 (1804), I had to upgrade my kernel from vanilla to kernel-lt from ELRepo. My NVidia GeForce 210 would only work with the driver provided by NVidia, which in turn required a more recent kernel than 3.0.10. Anyway. Right now here's all the kernels that I have on my workstation: [root at alphamule:~] # rpm -qa | grep -i kernel

Netfilter fails to filter traffic from a netblock?
Hi Everyone, We rent a CentOS 7 VM from GoDaddy. We received a warning about excessive cpu usage, and a threat to cancel our service. We tracked it down to Apache and someone hammering our web server. The offending host is 59.64.129.175. To err on the side of caution we attempted to block the entire netblock. According to whois data, that's 59.64.128.0-59.64.159.255. iptables -A INPUT

looking for ideas about how to create a constant data stream
Hi, I'm looking for a good way to create a constant data stream that will occupy a bandwidth of about 2--5Mbit/sec between two remote hosts over the internet. I have full access to the hosts involved. My first attempt to use scp to copy data from /dev/null on host A to /dev/null on host B, but scp says '/dev/null: not a regular file'. If something like that would work, I would
