It seems that a recent 5-STABLE limits the rate of successful incoming logins. Is it true? We failed to find the relevant code neither in openssh nor in openpam. The symptoms are that after a big number of quick successful logins sshd starts to delay or block login attempts for as long as 10 seconds. Does someone know anyhting about such behaviour or is this some obscure configuration problem (read: pilot error)? -- Alex Kapranoff, $n=["1another7Perl213Just3hacker49"=~/\d|\D*/g]; $$n[0]={grep/\d/,@$n};print"@$n{1..4}\n"
