Sometimes it may already be helpful to capture a translator's `stdout` and
`stderr`, for example in this situation where [[translator/pfinet]] was
silently dying all the time, without any console output:
$ sudo settrans -fgap ↩
/servers/socket/2 ↩
/bin/sh -c 'exec >> /root/pfinet.log 2>&1 && date && ↩
/hurd/pfinet -i eth0 -a [...]'
$ [...]
$ cat /root/pfinet.log
[date]
NET4: Linux TCP/IP 1.0 for NET4.0
IP Protocols: ICMP, UDP, TCP
TCP: Hash tables configured (ehash 65536 bhash 65536)
pfinet: ../../hurd.work/pfinet/ethernet.c:196: ethernet_xmit: Unexpected error: (os/device) invalid IO size.
(Trying to run [[GDB]] in this case was of no help -- due to a bug in GDB
(supposedly) it wouldn't catch the fault.)
Be made aware that both `stdout` and `stderr` will be block bufferend and no
longer line buffered when doing such a redirection, so you'll have to arrange
for appropriate `fflush`es on these, or force them to be line buffered again
using the appropriate glibc magic (`setvbuf`). Otherwise you'll see text in
the output files only if either glibc herself decides to flush (after some KiB
of text) the after translator exits.
There is also a [[related open issue|service_solahart_jakarta_selatan__082122541663/translator_stdout_stderr]].
