Re: ssh broken?


I also got the same problem since a few days.

I have done a complete reinstall of cygwin, but it didn't help.

I get "ssh: connect to host ... port 22: No error" immediately regardless if the address I try towards actually exists or not.

I used wireshark on the destination computer, and saw some traffic on port 22 when I tried to connect to it. Havn't looked into it in detail.

I downloaded and installed putty, and it works fine.

Tried to disable firewalls, no change.

I also noticed that I have some problems with the x-server.

startx gives
_XSERVTransSocketUNIXAccept: accept() failed

And i I try "xhost +" in the opened xterm i get
xhost: unable to open display "localhost:0.0"

Hi list,

since a few days, my Cygwin ssh is broken. On the other hand, I run sshd as a service, that works just fine.

But the problem with my ssh:

And it returns immediately without a connection. So it seems to bail out at the 'Connecting to' stage. The same happens whatever I address I try to connect to, like e.g. localhost (sshd allows remote login without problems). The same problems with scp.

However, /bin/ping just works fine.

$ ssh -version
OpenSSH_4.7p1, OpenSSL 0.9.8g 19 Oct 2007
Bad escape character 'rsion'.

Today (like yesterday, 2nd attempt), I reinstalled Cygwin, with lots of packages (gcc, gdb, flex, openssl, svn, cvs, ...). Made no difference at all, so maybe the problem is not in Cygwin but somewhere else?

I am also having problems with subversion: I get a comparable error when I want to check out via svn checkout https://svn.blaaaaaa....... When I run TortoiseSVN, this checks out the same URL fine. But then I get wrong line endings for working with Cygwin, so that doesn't solve my problem.
