Hello everyone, I am quite new to lwip and I tested the lwip minimal example in the lwip-contrib folder under a linux (Ubuntu) system. The example is running, I see SNMP output messages but I am not able resp. I don't understand how to use the echo server. I turned on all debug messages and used a simple echo client program. When sending some data to the echo server I got the following error message:
./SimpleEchoClient -a 192.168.0.111 -p 7 ECHOCLNT: Error calling connect() The output of the echo server is: ... tcp_slowtmr: no active pcbs tcp_slowtmr: no active pcbs tcp_slowtmr: no active pcbs tcp_slowtmr: no active pcbs tcp_slowtmr: no active pcbs tcp_slowtmr: no active pcbs pbuf_alloc(length=42) pbuf_alloc: allocated pbuf 0x637538 pbuf_alloc(length=42) == 0x637538 ethernet_input: dest:ff:ff:ff:ff:ff:ff, src:7a:13:c2:69:33:0e, type:806 pbuf_free(0x637538) pbuf_free: deallocating 0x637538 tcp_slowtmr: no active pcbs tcp_slowtmr: no active pcbs pbuf_alloc(length=42) pbuf_alloc: allocated pbuf 0x637538 pbuf_alloc(length=42) == 0x637538 ethernet_input: dest:ff:ff:ff:ff:ff:ff, src:7a:13:c2:69:33:0e, type:806 pbuf_free(0x637538) pbuf_free: deallocating 0x637538 tcp_slowtmr: no active pcbs pbuf_alloc(length=42) pbuf_alloc: allocated pbuf 0x637538 pbuf_alloc(length=42) == 0x637538 ethernet_input: dest:ff:ff:ff:ff:ff:ff, src:7a:13:c2:69:33:0e, type:806 pbuf_free(0x637538) pbuf_free: deallocating 0x637538 tcp_slowtmr: no active pcbs etharp_timer could that be a problem with the tap0 device? Any hints how can I debug this? best Matthias ᐧ _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
