Hi guys,

I am trying to capture some tcpdump for a specific wireless client 

i am able to SSH into the EAP245 using Putty 

tcpdump - h displays the version numbers 

/bin $ tcpdump -h
tcpdump version 4.2.1
libpcap version 1.1.1
Usage: tcpdump [-aAbdDefhHIKlLnNOpqRStuUvxX] [ -B size ] [ -c count ]
                [ -C file_size ] [ -E algo:secret ] [ -F file ] [ -G seconds ]
                [ -i interface ] [ -M secret ]
                [ -r file ] [ -s snaplen ] [ -T type ] [ -w file ]
                [ -W filecount ] [ -y datalinktype ] [ -z command ]
                [ -Z user ] [ expression ]

However when i trytcpdump -n host 192.168.0.126 i get no suitable device found

/bin $ tcpdump -n host 192.168.0.126
tcpdump: no suitable device found
/bin $
 

What am i doing wrong 

Thanks,
