This morning, the Firefox (45.3.0) installed (upgrade) just a few days ago has crashed already a half dozen times. Anyone else having the same problem?

script to make webpage snapshot
by Valeri Galtsev 12 Aug '16

12 Aug '16

Dear Experts, Could someone recommend a script or utility one can run from command line on Linux or UNIX machine to make a snapshot of webpage? We have a signage (xibo) and whoever creates/changes content, likes to add URLs of some webpages there. All works well if these are webpages on our servers (which are pretty fast), but some external servers often take time to respond and take time to assemble the page, in addition these servers sometimes get really busy, and when response is longer than time devoted for that content in signage window, this window hangs forever with blank white field until you restart client. Trivial workaround: just to get snapshot (as, say daily cron job), and point signage client to that snapshot definitely will solve it, and simultaneously we will stop bugging other people servers often without much need for it. But when I tried to search for some utility or script that makes webpage snapshot, I discovered that my ability to search degraded somehow... Thanks for all your pointers!

Linux TCP flaw
by Andrew Dent 12 Aug '16

12 Aug '16

Hi So after reading this, felt I should apply the fix to a CentOS6 VPS that I have. http://www.zdnet.com/article/linux-tcp-flaw-lets-anyone-hijack-internet-tra… The article doesn't talk about CentOS or Redhat, but I assume the problem is the same, and hoping the solution is the same. However that doesn't seem to be the case. [root@vps ~]# uname -r 2.6.32-042stab108.7 [root@vps ~]# sysctl -a | grep ack_limit net.ipv4.tcp_challenge_ack_limit = 100 [root@vps ~]# vi /etc/sysctl.conf > Append > net.ipv4.tcp_challenge_ack_limit = 999999999 > to end of file [root@vps ~]# sysctl -p net.ipv4.ip_forward = 0 net.ipv4.tcp_syncookies = 1 error: permission denied on key 'net.bridge.bridge-nf-call-ip6tables' error: permission denied on key 'net.bridge.bridge-nf-call-iptables' error: permission denied on key 'net.bridge.bridge-nf-call-arptables' error: permission denied on key 'net.ipv4.tcp_challenge_ack_limit' [root@vps ~]# sysctl -a | grep ack_limit net.ipv4.tcp_challenge_ack_limit = 100 Am I getting a permission denied because of there is a different solution, or the problem doesn't apply to our VPS or some other reason? Regards Andrew Dent

I also don't want to get the content ("mirror") of stuff that URL points to on variety of "depths" - I don't want to use wget or curl for this reason. That is what I tried first and it breaks with at lest one of the web sites - they do seem protect themselves from "robots" or similar. And we don't need it.

I need to do it for a few webpages once a day, as they change daily. I prefer to once spend time on making cron job, and forget about it forever. Hence I need it done from command line.

CentOS 7: System log has repeated lines: Started session 123 of user root.
by therbur 11 Aug '16

11 Aug '16

The system log (/var/log/messages) of a CentOS 7.2 system has frequently-repeated message line pairs like: Jul 18 14:00:01 localhost systemd: Started Session 307 of user root. Jul 18 14:00:01 localhost systemd: Starting Session 307 of user root. where the session number increases each time. Looking around on this, e.g. Red Hat Bugzilla bug 727315, it looks like it's when crond starts a task; it looks like it might be fixed - I would think that would be in CentOS but don't know how to find/compare the Fedora and CentOS systemd versions to know for sure. I found a post on a workaround - in /etc/systemd/system.conf to change the line: #LogLevel=info to: LogLevel=notice I did that and rebooted, and it has stopped the messages. I'm worried though that this may have knocked out something of actual interest from the syslog. So my question is, is there a better way? A way that info messages could go to some other log, or better yet, a way that those particular "session" messages, and only those, could go to some other log or be filtered out?
