'''Mosh'''（{{lang|en|mobile shell}}）是一套從用戶端連到伺服器端的軟體。類似於[[Secure Shell]]<ref>{{Cite web|url=https://www.linux.com/learn/mosh-pit-mobile-shell-replacement-ssh|title=Into the Mosh Pit: A Mobile Shell Replacement for SSH|accessdate=2018-01-18|archive-date=2018-10-26|archive-url=https://web.archive.org/web/20181026025144/https://www.linux.com/learn/mosh-pit-mobile-shell-replacement-ssh|dead-url=no}}</ref>，但還針對對行動環境的特性調整。<br />
<br />
== 特性 ==<br />
* Mosh不綁定使用者端的IP地址，這使得使用者從行動網路（像是[[3G]]、[[4G]]）與[[WiFi]]之間切換時，不會造成連線中斷。<reF><br />
{{Cite web|url=https://www.techopedia.com/2/28746/tech-support/linux/mosh-secure-shell-without-the-pain|title=Mosh: Secure Shell Without the Pain|accessdate=2018-01-18|date=2012-10-19|archive-date=2020-09-27|archive-url=https://web.archive.org/web/20200927102218/https://www.techopedia.com/2/28746/tech-support/linux/mosh-secure-shell-without-the-pain|dead-url=no}}<br />
</ref><br />
* Mosh保持連線開啟，當此用者斷線時，伺服器端只會認定為暫時離線（{{lang|en|sleep}}）讓使用者可以稍候連回來。相對的，SSH因為透過TCP，在使用者斷線時會造成連線中斷。<ref>{{Cite web|url=http://www.networkworld.com/article/2189813/wireless/mit-researchers-chart-a-new-approach-for-mobile-internet-protocols.html|title=MIT researchers chart a new approach for mobile Internet protocols|accessdate=2018-01-18|date=2012-07-06|archive-date=2018-05-25|archive-url=https://web.archive.org/web/20180525150021/https://www.networkworld.com/article/2189813/wireless/mit-researchers-chart-a-new-approach-for-mobile-internet-protocols.html|dead-url=no}}</ref><br />
* Mosh會試著在本地端馬上顯示使用者所輸入的按鍵，這使得使用者會感覺到更少的延遲。<ref>{{Cite web|url=http://www.linux-magazine.com/Issues/2012/144/Mosh-and-AutoSSH|title=Tools for channeling SSH over an unreliable connection|accessdate=2018-01-18|archive-date=2020-10-21|archive-url=https://web.archive.org/web/20201021160930/https://www.linux-magazine.com/Issues/2012/144/Mosh-and-AutoSSH|dead-url=no}}</ref><br />
<br />
Mosh主要的缺點在於需要額外的設定，以及缺乏某些SSH能提供的功能（如连接转发）。<br />
<br />
== 設計 ==<br />
相較於[[SSH]]，Mosh運作於不同層。SSH透過[[传输控制协议|TCP]]雙向傳輸資料，Mosh則是在伺服器端模擬終端機，得知終端機上的內容後，再依據用戶端的網路速度計算要更新到用戶端的內容<ref name="usenixatc12">{{Cite web |url=https://www.usenix.org/conference/atc12/technical-sessions/presentation/winstein |title=Mosh: An Interactive Remote Shell for Mobile Clients |accessdate=2016-04-27 |archive-date=2020-08-06 |archive-url=https://web.archive.org/web/20200806052457/https://www.usenix.org/conference/atc12/technical-sessions/presentation/winstein |dead-url=no }}</ref>。這使得Mosh在速度不快的網路表現的很好。<br />
<br />
== 支援系統 ==<br />
Mosh支援大多數的[[Linux]]套件、[[Mac OS X]]、[[FreeBSD]]、[[NetBSD]]、[[OpenBSD]]、[[Android]]、[[Solaris]]、[[Cygwin]]，以及[[Chrome App]]。<br />
<br />
== 效能 ==<br />
=== 漫遊 ===<br />
Mosh使用了State-Synchronization Protocol（SSP）<ref>{{Cite web |url=https://www.helpnetsecurity.com/2012/07/09/mit-unveils-a-new-internet-protocol-for-mobile-clients/ |title=MIT unveils a new Internet protocol for mobile clients |accessdate=2016-04-30 |archive-date=2018-10-26 |archive-url=https://web.archive.org/web/20181026025052/https://www.helpnetsecurity.com/2012/07/09/mit-unveils-a-new-internet-protocol-for-mobile-clients/ |dead-url=no }}</ref>，這使得Mosh支援單封包漫遊<ref>{{Cite web |url=https://mosh.mit.edu/mosh-paper-draft.pdf |title=Mosh: An Interactive Remote Shell for Mobile Clients |accessdate=2016-04-30 |archive-date=2016-03-14 |archive-url=https://web.archive.org/web/20160314105050/https://mosh.mit.edu/mosh-paper-draft.pdf |dead-url=no }}</ref>。當用戶端切換IP位置時，不需要額外的封包進行認證，而用戶端也不需要知道自己已經切換位置了（這包括了用戶端可能使用NAT，而NAT本身切換IP位置）<ref name="usenixatc12"/>。<br />
<br />
=== 封包遺失 ===<br />
在Mosh作者的研究中，作者測試在29%封包遺失率的情況下，Mosh所使用的SSP比SSH有效降低大約五十倍的平均回應時間（從16.8秒降為0.33秒）<ref name="usenixatc12"/>。另外由[[史丹佛大學]]學生的研究則顯示大約30倍，從5.9秒降為0.19秒<ref>{{Cite web |url=https://reproducingnetworkresearch.wordpress.com/2013/03/14/mosh-cs244-13/ |title=CS244 '13: MOSH |accessdate=2016-04-30 |archive-date=2020-11-18 |archive-url=https://web.archive.org/web/20201118034543/https://reproducingnetworkresearch.wordpress.com/2013/03/14/mosh-cs244-13/ |dead-url=no }}</ref>。<br />
