MikroTik

I have a RB500 running 2.9.6, and a PC running 2.9.18. When viewing the queues, the later version does not show the Destination Address column. Sometime between 2.9.6 and 2.9.18, was the Destination Address column dropped from the Queues list when using winbox?

Im detecting traffic coming from my MT to broadcast (255.255.255.255) on the following ports:

rrac 5678/tcp Remote Replication Agent Connection
rrac 5678/udp Remote Replication Agent Connection

any ideas?

cheinzle

I have not seen a sensible suggestion how this could be worked around - if someone has one, I'm sure MikroTik will consider doing this... I'll take a shot at suggestions: Keep the name the same as before the interface was changed, but tag it as unavailable (rather than just 'unknown'). Allow the us...

Ive noticed in some cases that when I swap out a PCI ethernet interface card (on a PC based machine), the MT OS loses track of interface names, as well as ip addressses, routes, etc associated with that interface. Obviously its difficult for the OS to make accurate assumptions about what name should...

whilst upgrading RB230 OS, LILO had become corrupted. It now hangs with a message: Booting IDE... LILO 22.3.4 Loading System............. and never gets any farther. I need to recover the device, getting MT OS reinstalled. Whats the best way to do this?? Etherboot?? If so, has anyone done this succe...

i have RB500 running 2.9rc7. I have 2 interfaces that are configured for point-to-point links, with /29 networks on each. When I enable OSPF on each interface, a *new* corrosponding route appears for that network with an INVALID tag. The old route (not invalid) remains, as well. OSPF (and all networ...

What do you exacty mean with redirections ???
Dou you mean ICMP redirection that goes under icmp type - 5 ?

redirects as desribed by the following:

cheinzle

is there any way to turn on/off ICMP redirects on the MikroTik?

I have 3 routerboard 500/564 combos. when running RC5 or RC6, the following occurrs with each (all of them): 1) boot router 2) plug ethernet cable into any port on 564 that belongs to a bridge group 3) router crashes & reboots after 4-8 seconds if the ethernet cable is already plugged in when th...

ive crashed my RB230 trying to load 2.9RC4; LILO freezes. Im trying to recover the flash connecting to an IDE adapter on a computer runing linux. Can anyone help me out on what exactly needs to be done to get the flash back into a bootable state?

cheinzle

i stupidly had a queue statement for the /26 that the IP was in that was limited to 100b/s. Increasing it to 1000b/s was enough to get a reply.

cheinzle

got it working, with many humble thanks to Arnis.

I have a PC based MT 2.8.23 with 4 ethernet interfaces. On one interface I have configured a dozen or so IP addresses, each in a different subnet. My problem is: From the local console, I can ping every IP address but one. There are no firewall rules, NAT rules, Mangle rules, etc. The machine basica...

cheinzle

actually, im getting NO response from the other IP addresses, using MRTG cfgmaker or Linux snmpwalk. Im expecting the same device OIDs from each of the IP addresses.

I currently am reading from the IP address that works, but Im wondering why the other(s) dont respond to SNMP

cheinzle

i have a routerboard running 2.8.26. it has a 4-port ethernet pci card installed. I have 2 interfaces that are connected to the rest of the network, each with their own IP address. both are pingable from a server running MRTG. I cannot get SNMP response from *only* one ip address, the other works fi...

cheinzle

i guess you might try a freeware ftp program, such as WS-FTP, that has that feature availble

cheinzle

is it perhaps a 'passive transfer' setting? try toggling passive mode.

cheinzle

... When the flow stops, the timer resets, and the process starts over. When you say stops, how close to zero traffic does it need to be, and for how long? If they drop to zero traffic for, say, 2 seconds, is that enough? If a customer has a 'permanant' trickle of traffic, does the burst timer rese...

Why doesnt MT document THIS !!!!?????????????

Ive asked myself that question many times.

cheinzle

that works for connected links, but what about when your upstream provider has routing/connection problems. You then dont have the luxury of checking for link status.

cheinzle

I use MT primarily for bw control. I have two units running, each with 300-400 simple queue entries. In addition to limiting bandwidth, I also use the device to lock down unused or cancelled users. My question is, is it better from a CPU standpoint to lock down unused IP addresses by limiting the ba...

cheinzle

yeah, that doesnt seem to be a problem in my case. the mrtg server is connected directly to the MikroTik, with nothing in between. No Firewall rules that I can see that would be blocking, and I put in a passthrough statement for input and output to log SNMP traffic: traffic comes in but doesnt leave...

cheinzle

what was your solution? Im having the same problems

cheinzle

Im interested in knowing if this is supported, as well, and not just with routerboards.

cheinzle

now running 2.8.18.

the original question still remains unanswered, however. It seems to be some kind of authentication problem, as even console login fails with error "Connect failed (error no=111). died with signal 6 on Mon, Dec 6 5:18:00 2004"

cheinzle

yeah. I read that. What Id like to know is *why*. Many of us are putting the quality and relaiability or our networks and livelyhood in the hands of this software, and detailed explanations of system problems i think should be a minimum expectation. Such questions should never have to be posted to t...

cheinzle

thanks. very nice.

cheinzle

can anyone tell me what has changed that allows 2.9 to boot so quickly (or rather, why does 2.8 boot so slow) with lots of queue list entries?

cheinzle

suddenly, all attempts to connect to the MTK are refused; web, winbox, telnet, ssh, ftp. no changes affecting connections have been made. this is like the 3rd time in 6 months this has occurred. running v2.8.8. any ideas?

cheinzle

If I use the following to find all routes with a distance setting of 110:

> :set i [/ip route find distance=110]

then print the results:

> :put $i
*170,*182,*17A,*179,*177,*178,*16F,*17E,*176,*172,*175,*174,*173,*171,*17D

I get a list of route numbers. Can I then count these?

cheinzle

Is there any way to count the number of routes in the routing table?

cheinzle

Im thinking of perhaps something like this: count the number of dynamic routes, and store that in a local (global) variable. every minute (or so), count the number of dynamic routes again, and compare it to the last time. If they are different, write the whole dynamic table to a file, log, or email....

cheinzle

I would like to know how to do this, as well.

cheinzle

are you talking about routes internally, or routes that you send/receive from your upstreams?

cheinzle

have you consdered not just how traffic will be routed out, but also how it will come back to you? Do you have a /24 or larger from one or both upstream ISPs?.

cheinzle

yeah, multiple gateways can do that, and not just on MTs. You might try setting the distance on one route. But I guess the bigger question is, why are you using 2 default gateways? Should either gateway have a path back to where you are connecting from. If you connect from the same IP (or subnet) al...
