Multicast Issues on Centos 7

@BedCruncher said:
Just realized maybe you were referring to have me run the UDP-Sender / UDP-Receiver commands manually?
Nope, I was asking you to run the command
ps ax | grep udpand show the output to us. From what I get you don’t seem to have any udp-sender processes running after you started multicast task. Please make sure you have a valid image on your server:ls -al /images/<img-name>(please post the output here as well!)… -

@BedCruncher No UDP-sender processes… please check you multicast.log to see if it actually starts any…
As stated in one of my earlier posts I see this in my multicast.log:

As well, show us what you have in the image directory:

touch /opt/fog/log/multicast.logand the selection was also missing from the Log Viewer menu. I verified the file permissions of that file compared to the other longs under that directory.Just downloaded build 7348 and am now getting

Following that screen, I let it run for a bit, then while it was doing the invalid session scrolling, I deleted and reinitiated a multicast session and it’s hanging at the same spot as previous.

@BedCruncher I am very sorry but without information (log file for example) I am not able to help. Posting the partclone picture is nice but does not really help I am afraid. Hope this does not sound ignorant, it’s not meant to!
We need to get some log output from the FOGMulticastManager (multicast.log)! Or at least see the udp-sender processes on the FOG server. Otherwise multicast will not work. Please try this:
service FOGMulticastManager restart tail -f /var/log/fog/multicast.logNotice the log path! Multicast daemon writes the log to /var/log…
-
@Sebastian-Roth said in Multicast Issues on Centos 7:
service FOGMulticastManager restart
tail -f /var/log/fog/multicast.logBelow is what that shows.
tail -f /var/log/fog/multicast.logCan you verify the permissions that you have on that logfile? such as user, group, and file permissions? No, I completely understand, I was just trying to post that in the hopes that it would provide at least some extra information for your troubleshooting.
On my system the path
/var/log/fogis actually a symlink to/opt/fog/logand I didn’t create this manually. Had to have been put in place on the installation.As near as I can tell fog is never actually writing to the multicast.log file. It was only getting what I had posted earlier when it was manually ran during the udp-sender/udp-receiver testing.

@BedCruncher Did you tun the service restart??? What do you get from this command?
ps ax | grep FOG -
Just finished the upgrade to 7356 and ran
ps ax | grep FOG 16001 ? Ss 0:00 /usr/bin/php -q /opt/fog/service/FOGMulticastManager/FOGMulticastManager & 16004 ?

@Tom-Elliott Turns out something is wrong with the services logs in current trunk! I don’t see multicast.log on a fresh latest install… Service is properly running. Probably something to do with the static/self switch I suppose?!?

@Sebastian-Roth Should be fixed in latest, sorry.

I’ve updated to version 7386 to try and get this part of things fixed. Will post back once I test this.

@BedCruncher What’s output if you go to (in the browser)
http://ip.of.fog.here/fog/service/ipxe/boot.php?mac=macofhostwithcolons
Where macofhostwithcolons is the mac address (with colons) of the host that’s setup to do this tasking?
-
@Tom-Elliott
Here’s the info. I also compared it to a second host that I had added to a group for multitasking, and it appears identical, barring the mac address of course. Let me know what else you can recommend and I’ll be glad to accommodate.#!ipxe set fog-ip 192.168.240.10 set fog-webroot fog set boot-url http://${fog-ip}/${fog-webroot} kernel bzImage32 loglevel=4 initrd=init_32.xz root=/dev/ram0 rw ramdisk_size=127000 keymap= web=192.168.240.10/fog/ consoleblank=0 rootfstype=ext4 rootfstype=ext4 mac=00:26:b9:aa:14:ec ftp=192.168.240.10 storage=192.168.240.10:/images/ storageip=192.168.240.10 web=192.168.240.10/fog/ osid=5 consoleblank=0 irqpoll hostname=0026b9aa14ec chkdsk=0 img=W7Px64PreSysprep imgType=mps imgPartitionType=all imgid=1 imgFormat= PIGZ_COMP=-6 hostearly=1 port=50028 type=down mc=yes imgfetch init_32.xz boot -
@BedCruncher When the client boots to begin the tasking, is it on a separate subnet from the 192.168.240.10 server?
-
@Tom-Elliott
No it’s not. I have the em2 interface controlling the DHCP server and have a cable running to a 5 port Gig switch. It’s a dumb switch with no special routing or anything. I even checked under the dhcpd.leases file and can find it there.lease 192.168.240.30 { starts 4 2016/04/28 12:50:28; ends 4 2016/04/28 18:50:28; cltt 4 2016/04/28 12:50:28; binding state active; next binding state free; rewind binding state free; hardware ethernet 00:26:b9:aa:14:ec; uid "\001\000&\271\252\024\354"; }EDIT:
Updated to build 7410 this morning to hopefully see if it might have been fixed.
EDIT 2:
Updated and initiated a new test and still getting the same results. -
Hey guys, I had to step away over the weekend. Has there been any new updates?
-
@BedCruncher Now that we have the logging back can you please try running udp-sender by hand again using the exact same command as seen in the logs?
-
@Sebastian-Roth
So I tried both of the udp-sender commandsudp-sender --file /opt/fog/.fogsettings --log /tmp/multicast.log --ttl 32 --nopointopoint --interface em2which results in
13:41:14.387632 Using mcast address 232.168.240.10 13:41:14.387698 UDP sender for /opt/fog/.fogsettings at 192.168.240.10 on em2 13:41:14.387708 Broadcasting control to 224.0.0.1displaying in the logs and then no task found
and also
cat /images/W7Px64PreSysprep/d1p1.img | /usr/local/sbin/udp-sender --interface em2 --min-receivers 2 --max-wait 600 --portbase 50028 --full-duplex --ttl 32 --nokbd --nopointopoint;cat /images/W7Px64PreSysprep/d1p2.img | /usr/local/sbin/udp-sender --interface em2 --min-receivers 2 --max-wait 600 --portbase 50028 --full-duplex --ttl 32 --nokbd --nopointopoint;which results in the same message as above, but not the repeated no active task found entries. I also updated to build 7470 earlier. It is acting differently. I don’t see that the udp-sender and udp-receiver are talking any more.
