[LTP] [question] tst_rhost_run.sh not installed

[Boyang Xue]

Hi,

I'm trying to build, install and run LTP like this:
```
git clone https://github.com/linux-test-project/ltp.git repo_ltp
pushd repo_ltp/
make autotools
./configure
make
make install
# export RHOST, LHOST, etc. test vars
export LTPROOT=/opt/ltp; export PATH=$LTPROOT/bin:$LTPROOT/testcases/bin:$PATH
./runltp -d /test -f net.nfs
```

During the test run, it complains that
```
/opt/ltp/testcases/bin/tst_net.sh: line 979: bash:: command not found
```
line#979 is:
```
eval $(tst_rhost_run -c 'tst_net_iface_prefix -r '$IPV4_RHOST || echo "exit $?")
```

I can find tst_net_iface_prefix in the $PATH, so it should be
tst_rhost_run which leads to the error.
Searching for tst_rhost_run in /opt/ltp and $PATH shows not found, so
is it a bug or did I miss something that the file wasn't installed?

It happens on the latest LTP:
```
# git rev-parse --short HEAD
5d8f9dfd6
```

Thanks,
Boyang

No tst_rhost_run is a shell function defined in tst_net.sh.
I guess the problem is your RHOST setup.
LTP supports two setups for network tests:
1. network namespace based. This is used if you don't set RHOST and LHOST.
2. Two-host setup, where RHOST points to a second host.

The important thing in two host setup is, that $LTP_ROOT/testcases/bin 
is in the PATH for the user, that is used on the RHOST.
I guess what happens in your setup is that tst_net_iface_prefix is not 
found on the RHOST, because it is not in the path.

Thanks Petr and Joerg!

Yes. I was testing with the two-host setup. Previously RHOST didn't
have LTP installed, so there's no tst_net_iface_prefix. After
installing LTP on RHOST and setting LTPROOT & PATH env variables
there, the error disappeared and it works well now.

Thanks,
Boyang
