similar to: "cipher none" alternatives ?

I was trying to use rsync to send files to a fileserver using an rssh restricted server. It refuses, saying that trying to override the shell with -e is forbidden. I didn't type "-e". When I look at the source, I see /* Checking the pre-negotiated value allows --protocol=29 override. */ if (protocol_version >= 30) { /* We make use of the -e

I recently upgraded my servers to 3.4p1 and have been having a problem connecting with an old Windows SSH1 client by Cedomir Igaly, and also with PuTTY which I just downloaded. I get a "CRC error". This is with OpenSSH that I built from the SRPM, setting the flag in the spec file for RHL 6. My RH6 ssh talks both ways to OpenSSH_2.9.9 (RedHat patch) and to sshd 3.4 on RedHat 7.2. My

I recently compiled openssh 3.4p1 for SGI Irix, and found the same problem I'd had with 2.5. Viz. that Irix /usr/include/paths.h defines _PATH_USERPATH, not USER_PATH, so that defines.h doesn't find it and we get the default, which is missing /usr/bsd (which on Irix has things like head, more, lpr) and /usr/bin/X11. This annoys the users, who want X11 to work. I added a test to

RedHat released sendmail-8.13.8-10.el5_11.src.rpm which includes sendmail-8.13.8-ssl-opts.patch which adds support for disabling SSLv3 and SSLv2 in sendmail.cf But as far as I can see there is no support in sendmail.mc - I can't see how to compile sendmail.mc to get the required line ServerSSLOptions in sendmail.cf Does anyone know how to do this ? -- Andrew Daviel, TRIUMF, Canada

(apologies for the length - there are questions at the end...) I've been running Linux for 20 years, and done a lot of dual-boots. I know that's old-school now, but I run Linux 95% of the time yet don't want to lose a Windows system I've paid for - but I've never tried removing it from a system and reinstalling the same licenced copy inside a virtual machine. I bought a

We had an incident recently where an openssh client and server were replaced with trojanned versions (it has SKYNET ASCII-art in the binary, if anyone's seen it. Anyone seen the source code ?). The trojan ssh & sshd both logged host/user/password, and probably had a login backdoor. Someone asked me what was their exposure if they used public/private keys instead of passwords. My

I think I have resolved my problem, but having typed most of this I might as well send it. I have OpenSSH_2.5.1p2 which I am trying to build on Irix 5 In Irix /usr/include/paths.h _PATH_ROOTPATH and _PATH_USERPATH are defined. defines.h looks for USER_PATH and _PATH_STDPATH and misses this, so that sshd does not include the path for X11 when users login. I copied a chunk of ifdef viz. #ifdef

I want to set up a machine which has an account with no password that can only be used locally, i.e. you cannot login over the network. The machine is in a room which is normally locked. It needs access to the network for videoconferencing, and this seemed a reasonable way to do things rather than putting passwords on post-it notes or Web pages. This is on a PC running RedHat Linux (7.0) I

the whois command in c6 references whois.v6nic.net for ip addresses in the 43.0.0.0/8 range (and maybe others). v6nic is no longer a valid whois server, any nets delegated to it should instead be delegated to apnic. i have no upstream connections... this change was made in the generic sources for jwhois some time ago I see this fix was introduced in F20 here,

I have Skype 2.1.0 running on CentOS 5, but it does not support video. At various times I have tried to install or run more recent versions on CentOS 5 and CentOS 6, but generally they fail for some reason, e.g. library requirements. We would like to run Skype in some conference rooms, for business reasons e.g. job interviews where some participants don't have access to more

We have a freeradius server using LDAP authentication against openldap. We have had freeradius-3.0.4-6 on CentOS 7 successfully communicating with openldap-servers-2.3.43 on CentOS 5. We need some features in freeradius-3.0.12. When I build that on CentOS 6, it initially works, but then develops TLS errors. We can search and authenticate against the LDAP server with Apache, and with

Hi all, Is there a straightforward way to enable the none cipher for v1 and v2 in the server? Please include my email address in your reply, as I'm not subscribed to this list. Thanks! Mordy -- Mordy Ovits Network Engineer Bloomberg L.P.

Hello all, I tried to connect to the server that supports protocol 1: # ssh -1 -o "cipher none" remotehost <No valid SSH1 cipher, using 3des instead> As per the code in sshconnect1.c, it has to alert the user about "none" cipher usage. try_challenge_response_authentication() { .... if (options.cipher == SSH_CIPHER_NONE)

Using stock OpenSSH 4.7 I found different behavior when trying to specify the use of the 'none' cipher depending on the command line option nomenclature. This is under linux 2.6.19-web100 using -ocipher=none [root at delta openssh-4.7p1-hpnv19]# /home/rapier/ssh47/bin/scp -S /home/rapier/ssh47/bin/ssh -ocipher=none -P 2222 ~rapier/2gb rapier at localhost:/dev/null rapier at

Hello, Does anybody know how cam I enable the usage of the 'none' cipher in OpenSSH 4.7 yours, Mihai

Hi, I was looking at the thread on the 'null' cipher and was wondering if you have done anything one it, if you need any help (or just encouragement ;)). I'm a radio experimenter (radio ham) and currently I'm using ssh illegally over the air, as I'm not legally allowed to encrypt sessions over the Radio Link.
