求助:putty失去響應(yīng),

luojm_24680

當(dāng)使用putty的SSH連接linux,如果有10分鐘左右沒(méi)有操作,就會(huì)失去響應(yīng),需要把PUTTY關(guān)掉,重新登錄linux是怎么回事,是PUTTY的問(wèn)題,還是LINUX的問(wèn)題,怎么解決,謝謝!

貼一下 sysctl -a|grep tcp 的結(jié)果

/etc/ssh/sshd_config

ClientAliveInterval=60

#表示每一分鐘，sshd都和ssh client打個(gè)招呼，看看它還在不在.


ClientAliveCountMax 15

#那么，將在15分鐘之后斷開(kāi)，其他以此類推

我把上面這一項(xiàng)加上了,還是不行,過(guò)一會(huì)還會(huì)失去響應(yīng),請(qǐng)?jiān)賻兔Ψ治?/td>

ClientAliveInterval=60是60秒。。。�？梢杂�(jì)算著給大一點(diǎn)。
