@leavic 同样是双击 tab 显示本地文件列表，显示远程文件是怎么做到的？用的 Mac Monterey 自带的 terminal （现在默认是 zsh 不是 bash ）

自从第一部 iPhone 入手，就把从 nokia 时代的习惯改了，告别 9 宫格开始全键盘。对我来说，全键盘虽然有一定概率按偏，但喜欢每次定位在需要的具体字母上，而不是多选组合。

这随便一开，一个月至少过一千了吧

工作关系，大量接触表格类 PDF

mac 上，从识别率和表格线调整等综合角度，我个人认为 abbyy 的 finereader 遥遥领先同类。如果文档源清晰度差，用 finereader 内置的工具先调整 dpi 。

还有一种低成本可靠方案，就是部分截图（比如件号 /描述分别竖着单独截）整体截也可以，但对原图清晰度要求很高，有一行不清晰就不能选中会导致错行。MacOS 自带的图片 OCR 功能识别。截图建议用 Real-ESRGAN 或者 waifu2x 先处理。

MAC 上 OCR 同类软件很多，但表格处理能力大多数没有

抖音选 4k ，目前最清晰，比上海本地的东方有线电视高清还清楚

@ETiV 上面大家提到的，但凡认知范围内，能操作的都操作了，剩下的就是没有看服务器端日志，主要是我不清楚怎么看是正确的，又怕大家觉得我伸手党，搜了大半天，进展慢。

google 到的资料有说看 var/log/system.log ，我看了就 2 行，如下。似乎并没有什么帮助
Nov 25 23:42:10 hilary_s-mbp sshd: hilary [priv][7893]: USER_PROCESS: 7896 ttys000
Nov 25 23:42:14 hilary_s-mbp sshd: hilary [priv][7893]: DEAD_PROCESS: 7896 ttys000

也有说去 /etc/ssh/sshd_config 打开 LogLevel VERBOSE 。 我打开 sshd_config 并没有发现 LogLevel 字眼。是直接添加“LogLevel VERBOSE” 吗？然后去哪里看，system.log 吗？毫无概念

同时也有说，用 ssh -Tvv ，确实如 25 楼结果，显示了更详细的 debug2 。特意去查了“we did not send a packet, disable method”，如 23 楼时所示，无所收获

看了 2 天，基本把可能造成的十来种可能性都看了，又感觉都是 linux 解决方案，而我的 ubuntu remote 机上本身就很顺利。感觉 mac 作为 remote 是一个另类，当然主要还是我的知识有限。

上个月，养了 10 年的狗生病走了

@PbCopy111 谢谢指导。我的理解是你指 remote 端 mac 这样改是吧，为防止出错，我两台 mac 都改了。已经 PubkeyAuthentication yes 。 没有添加 RSAAuthentication yes ，因为用的 ed25519 。然后 remote login off, remote login on （相当于重启了 hhd)，目前还是没效果。

@ETiV @tudou1514 谢谢帮助，试过了，都无效
我在 ssh -vvv 下，仔细看了过程，公钥 sent 正常，到私钥这步显示 debug2: we did not send a packet, disable method 。我按照网上资料，一般或者是因为权限，或者是因为 authorized_keys 内有错误，都检查了

@PbCopy111 求教 Mac 哪里查看是不是开启了 key 登录模式？

@ETiV 感谢帮助
ssh-add -L 显示 The agent has no identities.
在远程电脑里，用 vi 查看，可以看到公钥信息已经出现在 authorized_keys 中
ip 访问也是相同的结果，始终会要密码
用 basename $HOME 看了，用户名没问题

额外的调试：(不知道有没有用）
服务器端关闭 remote login(sharing)，然后 terminal 运行 /usr/ssh/sshd -d 看了 verbose output
显示：
hilary@hilary_s-mbp ~ % /usr/sbin/sshd -d
debug1: sshd version OpenSSH_8.6, LibreSSL 3.3.6
debug1: Unable to load host key: /etc/ssh/ssh_host_rsa_key
debug1: Unable to load host key: /etc/ssh/ssh_host_ecdsa_key
debug1: Unable to load host key: /etc/ssh/ssh_host_ed25519_key
sshd: no hostkeys available -- exiting.

@npe 这个试过了，也是一样结果，谢谢帮助。不过 ssh-copy-id 确实比手工方便。

@ETiV 你是指 authorized_keys 可以存放多 keys 是么？学习了，好在里面就这一个，以前没配置过。

目前已经尝试：
@xinge666 @PbCopy111 已经用 ed25519 重新生成，放到 vps(ubuntu 22.04)上，依旧成功免密登录，但放到 MacOs 上依然失败。同时结合了 @crab @dingwen07 的建议，已经添加到 keychain ，且 remote login 临时设置允许对象为 full ，仍然要求密钥。 @ETiV 用的 cp id_ed25519.pub .ssh/authorized_keys ，所以应该没有手工输入的错误，也谢谢建议。

服务器端和啰嗦模式，我都不熟悉怎么弄，再研究一下，谢谢大家！

@adoal 抱歉我不是很熟悉，如果是指 /var/log/system.log 里 sshd 相关信息的话，检查了似乎没有
@crab 谢谢帮助，我成功添加了，但还是始终提示需要密钥

一年一换和两年一换都有，看有没有吸引力，今年就没动力换

今天沙特比预想的厉害得多，阿根廷并没有踢出压制性。沙特防守逼抢有力度，反击又能控又能突，结果就能理解了。和昨天伊朗对比太明显，感觉伊朗是看到英格兰被吓死的，沙特今天格外自信。梅西今天好几个做球还是相当不错呀，总感觉打不开局面时应该让他突一下，他现在几乎很少持球推进了。
