[Xymon] Xymongrep in 4.3.17 does not load local hosts.cfg

[Wladimir K]

Hi,

I compiled xymon 4.3.17 on Suse 11 distribution successfuly and the
server is running. But when I call xymongrep I get the following:

xymon at n1000 > xymongrep test
2014-07-29 09:24:01 Cannot load
/opt/xymon/default/server/etc/hosts.cfg, or file is empty

Xymon is installed in /opt/xymon/default/.

The file exists and has the necessery permissions:

-rw-rw-r-- 1 xymon users 1308 2014-07-18 14:45
/opt/xymon/default/server/etc/hosts.cfg

The hosts.cfg is also not empty and worked with Xymon 4.2.3.

With strace I don't see that xymongrep even tries to open the file:

Actually, instead of opening the file it is trying to get it via network:
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 fcntl(3, F_SETFL,
O_RDONLY|O_NONBLOCK)  = 0 connect(3, {sa_family=AF_INET,
sin_port=htons(1984), sin_addr=inet_addr("127.0.0.1")}, 16) = -1
EINPROGRESS (Operation now in progress)
select(4, [3], [3], NULL, {15, 0})      = 1 (out [3], left {14, 999998})
getsockopt(3, SOL_SOCKET, SO_ERROR, [72058139498774528], [4]) = 0
write(3, "config hosts.cfg", 16)        = 16

Which does not work as the port is not 1984 but 1988. But why does it
try to make network connection and doesn't open the local file. And
even then it writes to stdout that it tries to open the file locally
but it doesn't.

Thanks in advance for your help.
