undokumented log msg. on CSS (httpc_listen | VrrpMain)

[e.hoehn]

Does anyone have a dokument which describs the following 2 log messages:

NETMAN-7: HTTPC:httpc_Listen:ERROR->no data received after SYN/ACK handshake

VRRP-4: VrrpMain: bad IP header received, Bman free'd

Thanks in advance,

Emanuel

these are 2 unrelated messages.

The first one is just a debug message that informs you the HTTP server did not receive any data after establishing the connection.

Simply reduce the netmann syslogging level back to 4 to get rid of the message.

VRRP main is related to the VRRP function.

The CSS does not follow the VRRP RFC, so if any other device in the same vlan as the CSS is using the standard VRRP, the CSS will complain.

Again, this is no big deal - it's just a warning.

The packet with the bad header was deleted anyway.

correct, this is not the http server, but the http client. It's the process doing http keepalive.

The message still indicates that the CSS did not receive a response from the other side.

This means:

The CSS sends HTTP keepalive and does not get any answer within the expected time, but was able to establish the handshake , right ?

The reason for my question is, our customer had a problem with a switch, which is in between 2 CSS's and he is thinking of tracking on this message for the future (to recognize such kind of problems)

this is a debug message.

It is really not recommended to stay at debug level.

Moreover, there are other messages to detect a server going down.
