xshell4连接ubuntu,报错No matching outgoing encryption

xshell4连接ubuntu,报错No matching outgoing encryption xshell4连接ubuntu系统,报错No matching outgoing encryption,没有匹配的算法。 xshell4连接centos、redhat没有问题。于是怀疑是不是远程连接工具的问题,由于就用putty连接,putty能够远程连接ubuntu系统,没有问题; 由于就在网上搜索解决办法,发现是加密算法没有匹配,而linux系统的加密算法一般都放在/etc/ssh/sshd_config中,在配置文件中加入下面三行的配置信息,重启sshd服务,解决问题。 解决步骤: 1. 输入命令 sudo vi /etc/ssh/sshd_config (可能需要再次输入密码) #在 /etc/ssh/sshd_config 中增加上述的三行配置信息( ubuntu中不能复制粘贴只能手敲 ) Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac

北战南征 提交于 2019-12-14 03:37:44
问题 The following dictionary gives the word and its value: keywords = {'alone': 1, 'amazed': 10, 'amazing': 10, 'bad': 1, 'best': 10, 'better': 7, 'excellent': 10, 'excited': 10, 'excite': 10} Following the dictionary are two tweets in a list in a list. For each tweet, we need to find which of the words from keywords are present in it. tweets = [['work', 'needs', 'to', 'fly', 'by', '', "i'm", 'so', 'excited', 'to', 'see', 'spy', 'kids', '4', 'with', 'then', 'love', 'of', 'my', 'life', '', 'arreic

瘦欲@ 提交于 2019-12-13 23:32:10
问题 In Excel Power Query, I have a table. Column A has single numbers. I want to mark those records where the Column A value matches a list. A cutdown version of the problem is: let TableA = Table.FromColumns({{1,2,4}}, {"A"}), ListB = {4,5,6 }, DPart = Table.AddColumn(TableA, "IsInB", List.MatchesAny(ListB, each _ = [A])) in DPart I get an error in the DPart line Expression.Error: We cannot apply field access to the type Number. Details: Value=4 Key=A Apparently, the code is trying to access the

Rails simulating Constraints and sub-Constraints

我与影子孤独终老i 提交于 2019-12-13 17:55:33
问题 I am building a scheduling platform with tasks for a current project Let's say there are some Global Constraints (money, people, etc.) for the project, and that each tasks also has individual Constraints. The big deal is that I have to match each Global Constraint to every Constraint of the tasks of a same project Now the real big deal, is that in addition to having a nature (financial -> Float, people -> Integer) the constraints can also have a type (ex : costs of wages, costs of raw

Design pattern appropriate for a modular feature matching application?

本小妞迷上赌 提交于 2019-12-13 03:48:30
问题 Since I got some negative comments on my system design on this question (concerning the implementation of such system), I hope that if I present the problem I could get some better suggestions. I am trying to design a modular application to be used for feature matching in video frames (e.g. matching on very close frames of a movie or a video, like "the product" in this article by Sivic, Zisserman). The idea is to allow for an easy switch between different feature detection algorithms as well

matlab template matching only for 0 (or 1) in matrix

问题 I'm a beginner in matlab programming and i'm having some troubles with template matching. I have a few white boxes with a black border (link for pic below) along with some text and I want to extract all the boxes,and there's also one that has an X in it(it's a multiple choice answer). In the beginning I used normxcorr2 , but the problem is that due to the many white pixels of the template, I get allot of irrelevant templates like only white spaces. I was looking for an algorithm that does

Java: Matching Phrases in a String

时光总嘲笑我的痴心妄想 提交于 2019-12-12 18:26:18
问题 I have a list of phrases (phrase might consist of one or more words) in a database and an input string. I need to find out which of those phrases appear in the input string. Is there an efficient way to perform such matching in Java? 回答1: A quick hack would be: Build a regexp based on the combined phrases Construct a set listing the phrases that haven't matched so far Repeatedly run find until all phrases have been found or end of input is reached, removing matches from the set of remaining
