Hi,
I have Centos 7 VM. Network guys are saying that TTL for multicast of this VM is set to 25, hence firewall assumes it is DDOS and drops the packets. On OS level, is there a way to know, what is TTL ?
I want to set it to 10. I found one this URL , and it gives me two options to set :
Code: # iptables -t mangle -A OUTPUT -d <multicast_ip_addr> -j TTL --ttl-set 64 Code: # firewall-cmd --direct --add-rule ipv4 mangle OUTPUT 0 -d <multicast_ip_addr> -j TTL --ttl-set 64 But I do not have firewall and iptables enabled on my servers. Is there any different way to set it to 10 ?
Please suggest.
Thanks

I have a seemingly simple problem. Analog TV reception with TVtime is horrible quality. A VCR is outputting NTSC ch.3 to an ATI TV Wonder 600. USB 2.0 is enabled in my laptops BIOS and I tried different ports, and digital TV works perfectly in Kaffeine, so it's not a bandwidth issue. The ATI TV stick is not getting too hot. CPU, GPU, and RAM usage are fine.

Here's a video demonstration

SessionProbe is a multi-threaded pentesting tool designed to evaluate user privileges in web applications. It takes a user’s session token and checks for a list of URLs if access is possible, highlighting potential authorization issues. It deduplicates URL lists and provides real-time logging and progress tracking.

An anonymous reader quotes a report from Ars Technica: Windows' infamous "Blue Screen of Death" is a bit of a punchline. People have made a hobby of spotting them out in the wild, and in some circles, they remain a byword for the supposed flakiness and instability of PCs. To this day, networked PCs in macOS are represented by beige CRT monitors displaying a BSOD. But the BSOD is supposed to be a diagnostic tool, an informational screen that technicians can use to begin homing in on the problem that caused the crash in the first place; that old Windows' BSOD error codes were often so broad and vague as to be useless doesn't make the idea a bad one. Today, version 255 of the Linux systemd project honors that original intent by adding a systemd-bsod component that generates a full-screen display of some error messages when a Linux system crashes. The systemd-bsod component is currently listed as "experimental" and "subject to change." But the functionality is simple: any logged error message that reaches the LOG_EMERG level will be displayed full-screen to allow people to take a photo or write it down. Phoronix reports that, as with BSODs in modern Windows, the Linux version will also generate a QR code to make it easier to look up information on your phone.

Does the Help button in the Current KDE Settings KCron module (System Settings -> Startup and Shutdown -> Task Scheduler) function correctly for you?

The button functions fine here in 15.0 but not Current. The KCron Help handbook is available when launching Help directly.

Just looking for confirmations. Likely I have something misconfigured.

Thanks.

Hello all! I have an old linux wild dog pro desktop that I want to get running again. I need to know if I can just go get a screen at Wal-Mart to use, or if I need a special screen for linux. Looking to get one on the smaller side... 21 inch would be great, as I have a rolling cart that I use in bed to go online with. Thanks in advance
