tried your script on 4.4 and received e-mail with backup file in it.
check your settings under /tool e-mail
Also may want to check system identity. Based on the script, using the system identity can sometimes cause problems if the name contains certain characters. Also, make sure your script permissions are adequate.
I found two Issues with Upgrade to 4.4, actually this might be board specific since I have seen this issue before.
Copy 4.4 Complete package file over to router via winbox, reboot. Does its thing, comes back online, router APPEARS to be working, well It is Everything on LAN side is accessible, and the three ports I have on a WAN side for VOIP and cable connection, ( eg ehters 2, 3 and 4 are on a bridge of their own) the VoIP phones work.
The problem is that there is NO NAT translation, and no internet accessibility from the LAN side, a Reboot does not fix the issue. Restoring the backup I just created before the upgrade will fix the issue after it restores and reboots.
This is where I found the second “bug” If you DOUBLE click on your backup file, a new window pops up, shwoing file name, TYPE Backup, Size 398.9KiB, Creation Date: Dec 24 2009… If you click on restore in this new window you get: Do you want to restore config and reboot, you click YES, then you get Winbox error " Couldn’t Restore configuration - no filename (5) "
BUT if you click your backup file ONE time in the file list, and restore at the top of the file list window, it will restore and reboot and work.
Not a big issue but caught my attention.
The real question I have is Why does my 493AH always have NAT issues after an upgrade, and on occasion at random times about every month or 1.5 months it will just stop NATTING, without being reboot, or without an upgrade. I have noticed though that on all the recent upgrades, 4.X it happens every time.
Happens under ROS 4.2 as well.
Hi
I’ve tested RouterOS 4.4 with an MPLS VPLS setup
I’ve found out that when you’ve got vlan interfaces tagging to bridge
the IP-Address is not set up correctly on boot up (not pingable …)
I’ve simply disabled an reenabled the ip address config
then it’s working till next reboot…
With RouterOS 4.3 there is no problem like this
I think this is an bug…
Problem is not in email, problem is in $bjmeno . Backup of the system is OK. Then email tool and “deleting” does not recognize the file. If I print this variable it looks the same as the name of the file. In version 3.x it is working.
Another script - which is working. I DO NOT understand this…
:local mserver
:local mkomu
:local msubject
:local bjmeno:set mkomu "> xxxxx@email.com> "
:set msubject (“Export” . [/system identity get name])
:set bjmeno ([/system identity get name] . “-” . [:pick [/system clock get date] 7 11] . [:pick [/system clock get date] 0 3] . [:pick [/system clock get date] 4 6] . “.rsc” )
/export file=($bjmeno)
#/system backup save name=$bjmeno:delay 30
:put ($mserver.“\n”)
/tool e-mail send subject=$msubject file=$bjmeno to=$mkomu body=("Backup " . [/system clock get date] . " mikrotiku " . [/system identity get name] . “.”)
:put ("Backup udelan do souboru " . $bjmeno . “\n”):delay 30
/file remove [/file find name=$bjmeno]
My backup/email script just works for 4.4 after marking sensitive policy. It was ok for 4.3 without sensitive option.
hello
i have a problem when upgrading my routers to 4.4 which is after upgrading to 4.4 all interfaces names return to default .
my routers are RB 493 v 3.20 .
i have about 40 routers waiting to upgrade . i need to know if there is any fix to this problem and if there are another problems
Thanx for hint. It was in these options. Now I hope it is working. The curious is - only the first script is sensitive to sensitive option, the second one for export RSC is working anyway.
So for the others - there is change in script policy in v4.4. 
System health shows strange temperature: on v4.2 temp was 36C, after upgrade to v4.4 - 78C.
RB450G
like mine…
build a bridge with 2x 23db dualpol panel , distance 13Km.
both sides RB411AH with R52n and MPLS/LDP as per Wiki.
A–ether->wlan1…MPLS/LDPtunnel…wlan1<-ether–B
( layer2 bridging , RSTP/STP off )
with bandwitdhtest from RB411 to other side RB411,
on ROS4.4 single 5Ghz mode, 10 minutes continu test (10Mbps both send/receive) ok. ( ping little higher, but no problem )
same test, but in 5Ghz-N mode wil start as should, but throughput drops within short time till almost 0.
tried all kinds of settings but only 5Ghz will give me stable link.
My idea looks like something to do with input/output channel/chain getting confused when load increases on the radio.
also what happens in software/hardware when horizontal/vertical is mixed up between both side ?
for example, on first Dual pol antenna i connected “horizontal” to “ant-a/MAIN” and “vertical” to “ant-b/AUX” on the R52n.
but did i on the other antenna the same ? and if not, what would happen ?.
This setup is one of our backup links and if Mikrotik staff would like to play with it for testing we are happy to contribute.
I have more… 110C (RB450G)
Dear Friends
All is well with 4.4 hotspot but the anyip is not working in 4.4 version.
Same here: 110C (RB450G)
mine in rb450g 4.4ROS:
Voltage: 22.1 V
88 C
is this normal???
i downgrade to 4.2 now the health is :
Volatge: 22.1
41 C
v4.5 fixes the temperature issues in RB
I have several rb450g acting as firewall, others as bw management, others as routers.
All of them never has major issues until today… one day after install 4.4
The issues has found in 3 rb acting as firewalls (over 8 total in production). The customers call us and said the service has become too unstable and slow, the ping are ok, but the navigation was bad (web pages never load). After our proofs, the solution was disabled all firewall filters rules, and then enabling again.
Really it seems a problem of the 4.4 version. For a while I setup a reboot scheduled script at 3 am every day in all the rb450g acting as firewall, to “clean” mistakes (or wathever else) and starting it again with a fresh start. I’m waiting for a new version to leave the 4.4
Any ideas?
4.1 seems to be the best for 450Gs/433s.. Have about 50 of em out in the field and they work like champs. Havent tried 4.4 on a 450 in production yet.
