Riccardo Murri's questions

While running a test to diagnose some alleged network problem, I got this output from ping:

--- r01c01b11n02 ping statistics ---
30000 packets transmitted, 29995 received, 0% packet loss, time 6309ms
rtt min/avg/max/mdev = 0.091/0.343/118.051/3.605 ms, pipe 9, ipg/ewma 0.210/0.130 ms
PING r01c02b06n01 (10.1.1.61) 56(84) bytes of data.

The pipe 9 part I had never seen before; currently, I only get it on this couple of hosts, and the actual number varies (e.g., could be pipe 8 or pipe 2).

What does pipe <number> mean in ping output?

We are using the Tivoli TSM Backup/Archive client to back up user files on a largish multi-user system. Users come from different countries and thus can create files according to multiple locales.

However, the Tivoli dmsc client insists that all file names are valid in the locale it was started in (e.g., root's locale) and does not backup files that are not valid in this locale:

Sending of object '.../x<B2>+y<B2>=z<B3>' failed
ANS4042E Object name '.../x<B2>+y<B2>=z<B3>' contains one or more unrecognised characters and is not valid.

I'm looking after either a config option that turns off file name validation, or a locale that makes any byte string valid. (E.g., ISO-8859-15 strings cannot contain bytes in the numerical range 128-159 which gives the error above.)

Is there a way to avoid this error and back up all files, regardless of the validity of their names in a locale?
