ssh_exchange_identification: Connection closed by remote host
hello, i built an ssh 2.5.1p2 package for solaris. it's installed into /usr/local (with sysconfdir=/etc) on an administrative host with write access to /usr/local. other hosts nfs mount /usr/local. i had a script copy the following files generated from the package install into each host's /etc directory: primes ssh_prng_cmds sshd_config ssh_config then ran ssh-keygen (copied from the install target of the Makefile) on each machine as well. i can ssh from the administrative host that actually has the package installed to other hosts, but i cannot ssh from the clients with nfs mounted /usr/local and copied /etc files. i don't see any errors in the logs on the remote host - anyone see what i'm doing wrong? pluto# which ssh /usr/local/bin/ssh pluto# ssh -V OpenSSH_2.5.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090600f pluto# ssh jnathan at examplehost ssh_exchange_identification: Connection closed by remote host pluto# ssh -v -v -v jnathan at atlsnlb1 OpenSSH_2.5.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090600f debug: Reading configuration data /etc/ssh_config debug: Rhosts Authentication disabled, originating port will not be trusted. debug: ssh_connect: getuid 0 geteuid 2 anon 1 debug: Connecting to atlsnlb1 [10.8.17.100] port 22. debug: Connection established. debug: identity file //.ssh/identity type 3 debug: identity file //.ssh/id_dsa type 3 ssh_exchange_identification: Connection closed by remote host debug: Calling cleanup 0x45580(0x0) debug: Calling cleanup 0x4b318(0x0) debug: writing PRNG seed to file //.ssh/prng_seed pluto# pluto# uname -a SunOS pluto 5.7 Generic_106541-14 sun4u sparc SUNW,Ultra-4 pluto# ls -al /etc/ssh* -rw-r--r-- 1 root other 1085 Mar 16 16:16 /etc/ssh_config -rw------- 1 root other 668 Mar 16 15:44 /etc/ssh_host_dsa_key -rw-r--r-- 1 root other 600 Mar 16 15:44 /etc/ssh_host_dsa_key.pub -rw------- 1 root other 525 Mar 16 15:43 /etc/ssh_host_key -rw-r--r-- 1 root other 329 Mar 16 15:44 /etc/ssh_host_key.pub -rw------- 1 root other 883 Mar 16 15:44 /etc/ssh_host_rsa_key -rw-r--r-- 1 root other 220 Mar 16 15:44 /etc/ssh_host_rsa_key.pub -rw-r--r-- 1 root other 1770 Mar 16 16:16 /etc/ssh_prng_cmds -rw-r--r-- 1 root other 6 Mar 16 16:21 /etc/sshd.pid -rw-r--r-- 1 root other 1432 Mar 16 16:16 /etc/sshd_config pluto# pluto# thanks, -jon -- Jon Nathan jon at rupture.net http://www.rupture.net/~jon/

> hello, > > i built an ssh 2.5.1p2 package for solaris.Did you build with tcpwrappers enabled? - I've seen this error when trying to ssh to a host that I wasn't in the hosts.allow file for. If tcpwrappers is enabled, you'll need to add the sshd service to that machine's hosts.allow file. Cheers, Simon.
Possibly Parallel Threads
- 2.5.1p1/p2 PermitRootLogin broke (Solaris)
- Segfaults with ssh from Red Hat 6.2 openssh-clients-2.5.1p2-1.i386.rpm
- savecore: warning: /kernel version mismatch: ...
- OpenSSH ssh-agent compat. problem (bug?)
