I change my network configuration and now I don't have this problem any more. Jose Guilberto /***************************************************/ Hello, When I run ssh between two computers I have a 3 second delay before I can login. I ran ssh with the verbose option and found out that the delay is in between the following lines: ... debug1: Installing crc compensation attack detector. debug1: Received encrypted confirmation. (*** 3 second delay here ****) debug1: Doing challenge response authentication. debug1: No challenge. I read the source code for ssh and found out that my problem is in file "packet.c". It stays for 3 seconds in lines: /* Wait for some data to arrive. */ while (select(connection_in + 1, setp, NULL, NULL, NULL) == -1 && (errno == EAGAIN || errno == EINTR)) ; Any body has an idea about why this is happening? Thanks for your help. Jose Guilberto
