My question is regarding the possibility of someone wiretapping the communication and repeat the action. What if an intruder notice that there's a secure session starting (by guessing at the dst IP address and unintelligible payload) and then start capturing all the packets on this session for the purpose of repeating the whole session again? The secure user could add/delete interfaces and

I see that: SSH uses the following ciphers for encryption: Cipher SSH1 SSH2 DES yes no 3DES yes yes IDEA yes no Blowfish yes yes Twofish no yes Arcfour no yes Cast128-cbc no yes Two ques re: sshd: 1) Using openssh, how do I configure which

Hello, I see that incase of command execution: :fork()" is called twice, in sshd. Once to spin off child sshd from parenat and second from child sshd, to execute command. Due to this I see 3 processes being created for each connection viz: 16398 0.0 0.3 1284 892 ?? S 4:33PM 0:00.05 sshd:child 16399 0.0 0.1 320 232 p4 Is+ 4:33PM 0:00.06 -sh -c foo_command 16401 0.0

Looking at openSSH INSTALL: To generate a host key, run "make host-key". Alternately you can do so manually using the following commands: ssh-keygen -b 1024 -f /etc/ssh/ssh_host_key -N "" ssh-keygen -d -f /etc/ssh/ssh_host_dsa_key -N "" But when I try latter, I get: (gdb) n 1 0x35a6 in save_private_key_ssh2 ( filename=0xb2d2c

I get error: %SSHD-3-ERROR: Could not load host key: /tmp/ssh_host_dsa_key: Bad file descriptor Jan 26 23:58:52: %SSHD-6-INFO: Disabling protocol version 2. Could not load host key Everything looks okay, the file exists, (it was generated using command: ssh-keygen -d -f ssh_host_dsa_key -N '') I also do 'ls' and find the file exists with permissions: -rw------- 1 root group

Hello, I donot know if this is a bug or a feature or something that I need to configure... I have: RCSID("$OpenBSD: sshd.c,v 1.122 2000/07/11 08:11:34 deraadt Exp $"); I am experiencing a weird symptom when I run sshd on NetBSD1.4.1. When I run sshd -d (debug on), everything is fine. If I run sshd as stand alone (w/o debug on), sshd is in hug state, after following output: server:

Hello, Looking at: http://www.openssh.com/features.html Under 'Free Licensing' section: "any licensed or patented components are chosen from external libraries (e.g. OpenSSL)" Can someone please enlighten me which components specifically have patent/ licensing restrictions from openSSL that are being used by openSSH ? Are any of these restricted by US export laws ? Thank

I see that commercial SSH version it is possible to run sshd in SSH1 using DES (i.e, accepting SSH-DES clients). I understand from Damien Miller that Cisco routers also run in only SSH1 DES mode. Is it possible in openSSH to configure sshd (compile-time/runtime) to run sshd in SSH1 or SSH2 mode and accept SSH1 or SSH2 DES clients ? [I would like to be able to run sshd in SSH1/DES mode ] Is

I have a question on authentication. In openSSH, how do I enable keys based authentication (RSA) ? (Normally a user creates private/public keys, then puts public key on server under ~/.ssh/xxx ). How can this be achieved using openSSH ? I did not see in doc (may be I missed something..). Is it enough: In sshd_config: RSAAuthentication yes 1) On server, where should the user's public key be

Hello, I have: SSH-1.5-OpenSSH_2.3.1p1 I find that this client displays error when I specify (from command line), '-c' [cipher] for SSH1. {for SSH2 looks okay}. Thus, if I specify: ./ssh -v -l user -c des -1 host or ./ssh -v -l user -c 3des -1 host I get error: bad cipher des [des] or error: bad cipher 3des [3des] respectively.... and client immediately exits ! But, this is okay:

Hello, I have sshd version:SSH_VERSION "OpenSSH_2.3.1p1" When I run (using inted.conf), at client-side I get error: Bad remote protocol version identification: 'sshd: no hostkeys available -- exiting. I have client: SSH Version 1.2.27 [i386--netbsd], protocol version 1.5. Compiled with RSAREF. What is the solution to above problem ? Thank you.
