Hello,
If you look, your gateway is listening as follows:
GwPrintMyHostAddr: my host addresses are :
1 : [172.17.30.13] MRTSRMDEV.crtsap.local (HOSTNAME)
2 : [127.0.0.1] MRTSRMDEV.crtsap.local (LOCALHOST)
Now the point to note here which is why I am asking you to check the host/dns entries is that entry (2) shown above shows 127.0.0.1 and then the fully qualified hostname of MRTSRMDEV. I would have expected it to look like the following:
2 : [127.0.0.1] loopback (LOCALHOST)
1. Your SAPLOCALHOSTFULL is wrong. It should be the fully qualified address.
2. It seems as though you are using DNS. So please run nslookup for the entries I asked you to check in the hosts file and post the output here.
Now you have mentioned this is the only system where is doesn't work. Have you tried cross checking with systems where it does work properly ?
KR,
A.
