Hi,
I was wondering if anyone could shed some light on what these printouts from
tcpdump (ppp0) mean.
I get these printouts when connecting 2 boxes (i386) with pppd both running
NetBSD 2.0_RC5. Both boxes have the same Multitech 128ST ISDN USB terminal
adapters. I've also set both of them up to use MLPPP (single channel PPP
exhibits the same issue though). Connecting using telnet is no problem, but
I get these printouts however when I try and fetch a file across the link
with ftp. The "get" command starts the file transfer ok, but the progress
just remains on 0%. It appears as if no data is being transferred.
I can confirm that ftp works fine with this setup when using V.120.
Can anyone tell me what this means?
