Question about Neighbour Table Overflow.
by zhen wang 08 Jan '15

08 Jan '15

Hi, all When use Centos 6.5,kernel version 2.6.431, I have continuous messages of "Neighbour table overflow" in messages. I have modified the gc_thresh1(512) , gc_thresh2 (2048) gc_thresh3 (4096) in /proc/sys/net.. path, But the messages occurs occasionally. some forum saied: They are probably realted to a kernel bug where the thresholds are in fact only half of the value that is set. See http://patchwork.ozlabs.org/patch/170385/ --- I didn't figure it out whether it is a bug and it is fixed . Why did this happen? Who can give me hand. Thanks.

SSI?
by Steve Thompson 08 Jan '15

08 Jan '15

All, What is the state of SSI (single system image) on CentOS 6/7 these days? I'm interested in this at present just for the fun aspect of trying it. Obviously openMosix is no more, but OpenSSI, Kerrighed and LinuxPMI appear to be dormant. TIA, Steve

I'm running centos 6.6 with the default 2.0.9-xxx dovecot. I run sa-learn against my spam_to_learn folder, then I wan to move those emails to a learned_spam folder. when I do a doveadm -Dv move -u user learned_spam mailbox 'spam_to_learn' ALL I get this result: usage: doveadm [-Dv] [-f <formatter>] <command> [<args>] altmove [-u <user>|-A] [-S <socket_path>] <search query> auth [-a <auth socket path>] [-x <auth info>] <user> [<password>] config [doveconf parameters] director add|flush|map|remove|status dump [-t <type>] <path> expunge [-u <user>|-A] [-S <socket_path>] <search query> fetch [-u <user>|-A] [-S <socket_path>] <fields> <search query> force-resync [-u <user>|-A] [-S <socket_path>] <mailbox> help <cmd> import [-u <user>|-A] [-S <socket_path>] <source mail location> <dest parent mailbox> <search query> kick [-a <anvil socket path>] [-f] <user mask>[|]<ip/bits> log find|reopen|test mailbox create|delete|list|mutf7|rename|status|subscribe|unsubscribe penalty [-a <anvil socket path>] [<ip/bits>] purge [-u <user>|-A] [-S <socket_path>] pw [-l] [-p plaintext] [-r rounds] [-s scheme] [-u user] [-V] reload search [-u <user>|-A] [-S <socket_path>] <search query> sis deduplicate|find stop user [-a <userdb socket path>] [-x <auth info>] <user mask> [...] who [-a <anvil socket path>] [-1] [<user mask>] [<ip/bits>] this doesn't even list a move command, yet the dovecot pages show it and give examples. any suggestions? thanks, -chuck --

Seems random to me - not repeating on the same box, and rare enough that it is hard to make any generalization except that it is painful to talk some remote helper through the recovery process - usually involving emailing some cell phone photos of the console to figure out which partition has the problem. -- Les Mikesell lesmikesell(a)gmail.com

Password Must Change using SSSD in Samba 4.1.10
by Ashish Yadav 07 Jan '15

07 Jan '15

Hi, I am trying to implement the *password must change at next logon* in CentOS 6.5 client using sssd 1.11.6 where Samba 4.1.10 is my backend server. Here are the list of things which I have done, 1. I have setup the CentOS to do the Domain login using sssd service. I can able to login into the CentOS client using Domain user's credentials from display and from SSH also, no problem at all. 2. Next thing which I want to implement is that password must change feature into Samba 4.1.10 server. To do that, I have been using Windows 7 ultimate which is already in Domain and I am using RSAT tools for users and groups where I have a option to check "password must change at next logon" option for particular user. After doing that Windows machine is honoring this and telling user to change the password and allowing user to login after changing the password. 3. As far as the CentOS client is concerned, it was not honoring the password must change and allowing user to login without asking for password change using sssd with current password. Here is the configuration file of sssd service, [sssd] config_file_version = 2 services = nss, pam domains = EXAMPLE sbus_timeout = 30 [nss] filter_users = root filter_groups = root reconnection_retries = 3 [pam] reconnection_retries = 3 offline_credentials_expiration = 0 [domain/EXAMPLE] entry_cache_timeout = 600 entry_cache_group_timeout = 600 min_id = 1000 id_provider = ldap auth_provider = krb5 chpass_provider = krb5 ldap_schema = rfc2307bis ldap_uri = ldap://smbad.intra.example.com:390/ ldap_search_base = dc=intra,dc=example,dc=com cache_credentials = true krb5_server = smbad.intra.example.com:8880 krb5_realm= INTRA.EXAMPLE.COM <http://intra.example.com/> ldap_default_bind_dn = cn=admin,dc=intra,dc=example,dc=com ldap_default_authtok_type = password ldap_default_authtok = 6pNEn7Eo3zmz9MxciGLx 4. I have also tried to achieve above thing using command line tool "pdbedit" but without any luck. Here is the link < http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/passdb.html#pdbe… > which I have followed. Please share your thoughts in order to help me and move forward to solve this problem. Thanks very much and regards, Ashishkumar S. Yadav
