Hello All, The changing of group for the root results in the following message with OpenSSH 3.9p1 "permanently_set_uid: was able to restore old [e]gid" The following change in uidswap.c fixes me the problem. /* Try restoration of GID if changed (test clearing of saved gid) */ - if (old_gid != pw->pw_gid && + if(getgid() != pw->pw_gid && (setgid(old_gid)

OpenSSH fips compliance
Hello All, Im using OpenSSH 4.2p1 statically linked with OpenSSL 0.9.7i. It looks now that a fips certified OpenSSL is now available at http://www.openssl.org/source/OpenSSL-fips-1.0.tar.gz . I like to know of any patches applicable for OpenSSH versions to make it fips compliant. Is there any idea for OpenSSH core team to make OpenSSH as fips compliant? What amount of work it needs at this

VisualHostKey vs. RekeyLimit vs. VerifyHostKeyDNS
Hello list, I'm not sure whether this is bug worthy or just my own insanity. I'm using 6.4p1 packages from Debian jessie and wheezy-backports. I like VisualHostKey, although it may not add any protection (other than not trusting ones own known_hosts file?), I've become accustomed to it as it seems that extra neurons fire when I log into a host and get a visual cue of what looks like

Possible bug: SSH doesn't prefer host keys listed in SSHFP records while connecting.
Steps to reproduce: 1. Run a SSH server with default configuration and point a domain to it. 2. Add SSHFP record to the domain, but only for Ed25519 key. 3. Attempt to connect with VerifyHostKeyDNS set to yes, but the rest of settings set to defaults. 4. OpenSSH defaults to ECDSA instead of Ed25519 and refuses connection because there is no ECDSA fingerprint in SSHFP records. A stopgap solution

Missing SSHFP RRs / VerifyHostKeyDNS & StrictHostKeyChecking
Y'all, Currently (OpenSSH_7.1p1) no distinction is made between when an SSHFP RR is missing from the result set (rather then being empty), which can lead to confusing error messages, (the "normal" warn_changed_key() blurb is emitted) e.g. when the presented host key and known hosts both match but there is no matching RR. Further, if VerifyHostKeyDNS and StrictHostKeyChecking are

samba and kerberos doubt
in our lab we have a kerberos + ldap server to authenticate the gnu/linux users and we have configured samba to work as a PDC authenticating the windows users. samba stores the password in encrypted format in /etc/samba/smbpasswd. The problem is when the password is changed by windows users we need to change the password of kerberos credentials. Is there a way in samba in to do that i.e to

Performance of scp with OpenSSH - 5.1p1
Hello All, As the release notes of SSH-4.7 version says that a new MAC algorithm (UMAC-64 - RFC4418) was introduced with OpenSSH-4.7 which gives much better performance, I was tempted to check out the enhanced speed provided with new version. So I downloaded OpenSSH-5.1p1 and build it on Solaris 10 with Sun Compiler CC. My test setup:- 1. Two Sunfire 440 with 2 CPU (1281 MHz) and 4GB RAM. 2.

openbsd-compat/getrrsetbyname.c: answer buffer size too large for EDNS0 and glibc
Hello. I have an issue with SSHFP lookups using "VerifyHostKeyDNS=yes" and "options edns0" in /etc/resolv.conf (glib >= 2.6). getrrsetbyname() calls res_query() with a maximum buffer size of 65536. The glibc resolver truncates this value to 16 bits, reducing the query's advertised buffer size to 0. BIND appears to ignore it while Unbound returns a server failure.

hostkey checking
Hi! Is it somehow possible to disable the known_hosts checking for some hosts? The StrictHostKeyChecking affects only the asking about new computers, but doesn't affect the changed ones. I need it for the test computers, which are reinstalled twice/hour and I really don't like editing .ssh/known_hosts each time :-( Thanks Michal
