RE: snmpd -f (some issue)

Mahesh,

Try using the full path name when opening the file. Among other things snmpd will change its current working directory to / if the -f option isn't used.

Thomas:
 
The modified file is usmDHParameters.c (net-snmp-5.2.1/agent/mibgroup/snmp-usm-dh-objects/usmDHParameters)
 
Flat file (dh_prime) contains 180 bytes of Hexadecimal numbers. Right now, I don't have actual source file of usmDHParameter.c which i modified. I am writing below the lines code which I used.
 
The following are the lines of C code added in usmDHParameters.c in init_usmDHParameters() method.
 
char dh_prime[200];
int bytes_read=0, fd=-1;
 
fd = open ("dh_prime",O_RDONLY,0);
bytes_read = read(fd, dh_prime,180);
 
dh_prime (buffer) is copied in to dh->pointer() (I don't remember exact name) in BN_Hx2Bn() method. I commented default PRIME number used by net-snmp (which we get when querying usmDHParameters scalar OID) and copied with my prime value which is fetched from my flat file.

Thanks,
Mahesh

We cannot help here as long as you don't show your code.
