[chord] Re: problem with running sfsrodb

[Y Chen]

Hi

The problem passes through main() function of sfsrodb.C and comes with error
when reaches the last line of main()

main()
{...
return (sfsrodb_main (exp_dir, sk_file));
}

Can step futher till the line 812 of sfsrodb.C

Near the beginning of the sfsrodb_main() function:

int sfsrodb_main (const str root, const str keyfile)
{
...

812  dhash_cli = New refcounted <dhashclient> (lsd_socket);
...

Sorry to trouble you lot!

Yin
