You have to telnet into the machine:
telnet 192.168.1.254 8100
Then use:
username: root
password: t1t2t3a5
Then you can look for all files that have ".log"
find / -name *.log
which yields for me and by 1 downed chain:
/tmp/log/innominer.log
/tmp/log/analys3.log
/tmp/log/analys0.log
/tmp/log/analys1.log
/innocfg/log/miner.log
/innocfg/log/upgrade.log
I look at each one with cat:
cat /tmp/log/innominer.log
