SwOS Web interface error

Sun Sep 12, 2010 8:58 pm

I have 2 RB-250's. Both have been up for around 2 days.

Just now, I tried to look at the hosts tab and got this error on both switches:

INTERNAL ERROR:SyntaxError: missing ] after element list-missing ] after element list.

That is the only text displayed in the browser under the Hosts tab.
I am using Firefox 3.6.9, if that matters. Firebug reports no errors for the page.

Is host table contents displayed properly? When this error occurs, please, save it as "Web Page, complete" and send those files to support@mikrotik.com

I have sent the files by email and put this subject number in the email subject.

The page displays OK, but no, there are no hosts listed, just blank space.
Page source is here:

Does this problem occur when using any other web browser than Firefox 3.6.9?

I use Chrome, Firefox and IE to login the web management page(v.1.2), they have different error message on the "Host" tab:

Chrome v7.0.517 : ERROR:Lost Connection
Firefox v3.6.7 or v.4.0 beta : INTERNAL ERROR:SyntaxError: missing ] after element list-missing ] after element list
IE v8.x: INTERNAL ERROR:[object Error]-Expected ']'

Really weird...

Re: SwOS Web interface error

Using Firebug, I looked at the response to the ajax get to !dhost.b.
This is the response on one of my switches (mac addresses translated to 'xyz'):
[{adr:'xyz',prt:0x01,drp:0x00,mir:0x00},{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},
{adr:'xyz',prt:0x01,drp:0x00,mir:0x00},{adr:'xyz',prt:0x01,drp:0x00,mir:0x00},
{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},
...
...
...
...
{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},
{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},
{adr:'xyz',prt:0x10,drp:0x00,mir:0x00},{adr:'xyz',prt:0x10,drp:0x00,mir:0x00}
There is no closing ']' for the response.

The switch sends the data, but is simply missing the closing tag and the javascript doesn't like that.

What do I get for my hard work? 10 RouterOS licenses?

More information...

I repeatedly clicked 'Hosts' and then 'Static Hosts' and about 1 out of 10 times I get the 'Hosts' page complete.

When it fails, it is not sending all of the data, as the size when failing is 1,607 return bytes and when it works, the size is 1,896 return bytes.

Is there a timeout in the ajax request that is too short and times out if lots of hosts and therefore more data is returned?
I could look through the js, but.....

There are 39 hosts in my hosts table, if that matters.

I am 3,000 miles away from the switch and so my connection times are high, if that matters.
I asked someone local to the switch to test and they have no problem displaying the hosts table, so it would appear to be a timing issue.

I think I have earned 20 RouterOS licenses.

I suppose I should wait to post until AFTER completing my fact finding......

I did a simple get using a browser to http://<IP>:<PORT>/!dhost.b
The switch is behind an RB450G, so I have it dstnat'd.

When it works, I get the complete data, when it fails, I can briefly see the data in my browser and then ff reports the connection was reset.

If I earn 30 RouterOS licenses I'll do a packet capture of the entire process.

We can give you 30 SwOS licenses :) But you won't be able to use them, because SwOS is free of charge on all RouterBOARD switch products.
No answer to your question? How to write posts

Don't you mean to say: "You won't be able to use them due to all these problems?" ;)


OUCH....that hurts.

Seriously, does anyone want me to packet capture this?
I'll do it for karma and 1 RouterOS license.....final offer. 8)

MT repaired your switch remotely!

I have seen this come and go and it seems to depend on the length of the hosts table and the data transfer delay between the browser and switch.

If the hosts table is short and you are only a few hops away, no problem.

If the hosts table is long and you are 20 hops away - problem.

I didn't debug any further than that as I wasn't able to convince anyone to give me 20 ROS licenses....

New SwOS user here.

Just to say I have the same issue.

The following diags may or may not help...

If I connect over multiple hops directly to the RB250, I get the "Connection Lost" error.

If I ssh to a linux machine on the same subnet as the RB250 and setup a tunnel to port 80 on the RB250, so that the http connection is browser->localhost->tunnel->linux->rb250, then all is well.

I have the same problem on SwOS 1.2 (Hosts page):
INTERNAL ERROR:SyntaxError: at index 3073: syntax error-at index 3073: syntax error
Listing is working few seconds after reboot well, but later:
[*] sometimes it seems not to be complete (there is not my own PC's MAC on the list nor the other addresses that I am pinging);
[*] sometimes the error is displayed (the above or some other - for example "INTERNAL ERROR:SyntaxError: missing ] after element list-missing ] after element list");
[*] often there are some MAC addresses without marked port number.

There are about 100 computers connected to port 1 and only one on other ports. Maybe the problem is appearing only with so big count of MAC addresses?

Sometimes switch started to block everything - I could ping only to switch alone and no other device on other port.

And I also dislike that port numbers written on the switch case are opposite order with port numbers on web interface (port 5 is port 1 etc.)

I disagree with you, port numbers are ok (i checked fw version 1.0 and 1.2).

Which OS are you using and browsers?
I'm able to reproduce problem on MACOS with any browser, however it is fine on Windows/Linux.
Anyway we are working on the issue.
