How to find out my MTU

[ffi]

In windows it is done like: ping www.google.com -f -l XXXX

 

In linux I tried something like:

 

# ping -s 57 -M do www.google.com

PING www.l.google.com (64.233.183.99) 57(85) bytes of data.

64 bytes from nf-in-f99.google.com (64.233.183.99): icmp_seq=1 ttl=244 (truncated)

--- www.l.google.com ping statistics ---

4 packets transmitted, 4 received, 0% packet loss, time 3032ms

rtt min/avg/max/mdev = 17.315/26.672/36.490/8.888 ms

 

but my packets get fragmented above 56!? Am I doing something wrong?

Don't know about your packets, but you can find out your MTU value by entering

ifconfig -a

as root.
