Squid for CentOS 7 and available file descriptors
by Carlos A. Carnero Delgado 06 Apr '16

06 Apr '16

Hi, I'm installing a Squid instance for a large (ish) group of users. In the past I've had to increase the number of available file descriptors for the Squid process in order to avoid hitting the limits (and disrupting the service). It seems that the packaged Squid for CentOS 7 has a hardcoded value of 16386 maximum file descriptors <https://git.centos.org/blob/!rpms!squid.git/c6361861418913e2a375a3507da79ac…>. The relevant portion of that spec file is ⋮ --with-aio \ --with-default-user="squid" \ --with-filedescriptors=16384 \ --with-dl \ --with-openssl \ ⋮ Why this limit? Is there any merit to opening a bug or enhancement request somewhere? Other than that, what could I do next? A custom Squid build? Thanks a lot, Carlos.

Hi List, Does anyone know why the above URL is still using TLS V1.0. I can't connect to it unless I enable TLS V1.0 which I was under the impression that it should not be used anymore. Thanks for any enlightenment. Steve --

How to configure DNS server in RHEL 7 / CentOS 7
by Joe Smithian 05 Apr '16

05 Apr '16

How to configure DNS server and search domain common for all network interfaces not per device? The only reliable way I found we can set DNS name server and search domain in CentOS 7 is using nmcli which adds DNS name server and search domain to *a specific interface*, e.g. nmcli con mod eth0 +ipv4.dns [IP_ADDRESS]. But I want to set them for all interfaces weather they are configure and connected or not. How can we do that? More back ground information: I am using NetworkManager and nmcli tool to configure multiple wired Ethernet interfaces on CentOS 7. I want to set common DNS name server and search domain for all interfaces. /etc/resolv.conf is generated by NetworkManger and we cannot manually modify it. Thanks, Joe

Disabling network service in CentOS 7
by Joe Smithian 05 Apr '16

05 Apr '16

Hi all, I've recently started using NetworkManger service and nmcli tool, I like it much better than the old network service and manually modifying network scripts. I've seen many online questions on how to disable NetworkManger but I have the opposite question! I am wondering if it be OK to disable network service altogether and just use NetworkManger for configuring and managing Ethernet interfaces. I care about wired Ethernet interfaces only. I disabled network service and rebooted my machine without any networking problem but I wanted to conform that that would be OK.

VPN suggestions centos 6, 7
by david 05 Apr '16

05 Apr '16

Folks I would like to have my windows 7 laptop communicate with my home server via a VPN, in such a way that it appears to be "inside" my home network. It should not only let me appear to be at home for any external query, but also let me access my computers inside my home. I already have this working using M$'s PPTP using my home Centos 6 gateway/router as the PoPToP server. However, I am concerned about the privacy/security of such a connection. I have seen discussions of OpenVPN, OpenSwan, LibreVPN, StrongSwan (and probably others I haven't noted). I'd be interested in hearing from anyone who wishes to comment about which to use, with the following requirements: 1) As noted, it should be secure (anti NSA?) 2) Works on Centos 6 and Centos 7 and Windows 7 (and for the future, Windows 10) 3) Can be set up on the server with command line interfaces only (no GUI) And, should not be a nightmare to set up. Any thoughts? David

virt-manager virtual USB disk unavailable option

Hi, I have installed virt-manager 1.3.2 and I want to create a virtual USB disk (not USB host passthrough) but unfortunately I don't see that option when I try to add a new storage hardware. I have another PC with virt-manager 0.9.5 and Linux Mint and I have that option and it is working perfectly. My CentOS version is: 7.2.1511 Thanks in advance <https://www.google.com/search?q=host+passthrough+usb&spell=1&sa=X&ved=0ahUK…>
