Description jm493 2001-07-24 09:53:20 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.5-0.2.9 i686)

Description of problem:
ttcp -r  sends both the transmitted data, and the connection logging and
transfer statistics to stdout.  This adds junk to the end of file
transfers, and prevents using ttcp for network integrity checking.

How reproducible:
Always

Steps to Reproduce:
1. In window a$ ttcp -r > x.x
2. In window b$ dd if=/dev/zero bs=1 count=100 | ttcp -t localhost
3. in window a$ ls -l x.x ; cat -v x.x
	

Actual Results:  $ ttcp -r > x.x
ttcp-r: socket
ttcp-r: accept from 127.0.0.1
$ ls -l x.x ; cat -v x.x

========
e.g.  first 2 printfs go to stderr, rest get appended to data file (now 340
bytes instead of 100).


Expected Results:  $ /usr/src/redhat/BUILD/ttcp-1.12/ttcp -r > x.x

========
e.g. all the printfs go to stderr, transferred file is same size as sent.


Additional info:

It may also be a good idea to add a -q flag to supress all diagnositc
output.

Created attachment 24687 [details]
replace add stdout's with stderr

Comment 2 Pekka Savola 2001-07-24 10:22:17 UTC
Nice one.  Also fixed now in my src.rpm at
http://www.netcore.fi/pekkas/linux/ipv6/.

As for '-q'..  I think that'd be rather non-mainstream use, and better would be
just
to redirect stderr to /dev/null locally if needed.

Comment 3 Jim Wright 2001-12-10 23:13:48 UTC
this bug from july 2001 rawhide is still present in final RH72, and is still
marked new in bugzilla.

Comment 4 Radek Vokal 2005-02-22 13:42:30 UTC
I've pushed out new version of ttcp with several changes (mainly from Pekka's
upstream)
