Can not update ptp450i using CNUT

I have working link with two ptp 450i. Software version is CANOPY 14.1.1 BHUL450-DES, CANOPYBOOT 1.0, 110815.

I try to update to version 14.2 using CNUT version 4.9.18 under linux. Before setup this link i updated this devices using cnut and all worked fine. But now i can not update device.

I get this error

If i not mistaken the problem in timeout in http server on ptp device. But all process spend about 1 minute from start to end.

I try to enlarge timeout for http, https, telnet in web interface (setup 30 minutes) but this not solved my problem.

Hi BuryAlex,

Could you please tell me whether you have directly connected to the radio or trying to access the radio remotely?

Did you perform any configuration changes on the radio, did you change any SNMP or SNMP strings parameters?

Did you upgrade the CNUT between this and the past upgrade.

Are you facing this issue on one radio or multiple radios?

Regards,

G Krishnan

Link work and transmit data.  I have only one link and this link have problem with update.  When i  setup this link i update devices using ethernet. Now i try to update remoute device thru radio link.

I do not change CNUT version. I change some parametrs in snmp (i use snmp v3). I can access to both devices. I have acces via web interface and snmp (i can get information using snmpwalk).

When i see wireshark dump beetwen cnut and ptp450i i find succesfull snmp requests and responces.
