...I find that the number of the smbd connections may increase if the network is abnormal. And the repeated connections will exist for a long time (which is not accepted for me) So, I modify the following params and shorten the existing time of those repeated connections: TCP_KEEPCNT 3 TCP_KEEPIDLE 60 TCP_KEEPINTVL 15 My concern is that: Are there any risks of modifying above params to those values? ------------------------------------------------------------------------------------------------------------------------------------- 本邮件及其附件含有杭州华三通信技术有限公司的保密信息，仅限于发送给上面地址中列出 的个人或群组。禁止任何...

Hi all, I've been looking for an answer for this issue but Google didn't help. So I resource to the next best thing: the Samba mailing list. Question: Is there a way to automaticaly, after a certain amount of time, unlock a file after, for example, a client crash or network problem? I know how to do it manually of course, but that is, well, cumbersome. I've looked at

...ss not auto quit? If so, when I have many connections, my server can’t afford definitely. I find an answer to set auto close connection in http://www.spectrumscale.org/pipermail/gpfsug-discuss/2017-October/003975.html, the parameter: deadtime=10 and TCP level: TCP_NODELAY SO_KEEPALIVE TCP_KEEPCNT=4 TCP_KEEPIDLE=240 TCP_KEEPINTVL=15 But I didn’t find any description about these parameters. So I want to ask which is the right way to prevent this issue? And what is the effect?
