similar to: FWMark routing trouble

Hi everybody, sorry for posting again, however I''ve moved the problem now ;-) After digging a bit deeper, I''ve successfully set up the routing as such, it works for incoming as well as outgoing packets that take the default route. Changing some of the routes using IP works as well. When I mark some outgoing packets in order to send them via another route (the fast leased line

Hi everybody, I'm planning to set up our new mail system using the Dovecot mailbox server. It mostly works fine yet (it's quite straigt forward to set up, I'd say), but there's a thing I haven't been able to find out yet. We provide POP3 access for all users, but want to restrict IMAP access to some of them (because IMAP users tend to leave more messages on the server, thus

Hi everybody, we have three MGE UPS'. I've read all the documents I've found, but I haven't got the information I need. All three of them being attached to the same machine I need a way to identify which is wich (all three use the same driver). They power different systems (two of them running windows so that I can't easily setup a network-enabled software on two of them, as

Hi, I'm setting up our new mail system using dovecot as mailbox server. As our goal is to have many many small redundant (virtual) servers as components, for example a mailhub (just relaying mail) and a frontend smtp server (just accepting or denying mail in the first place and then forwarding it to the mailhub), etc. I want to run Dovecot on a different server than the main MTAs. The mailbox

In my system log file I get messages like: Jul 18 13:05:12 mint upsd[4025]: Host 192.168.145.12 disconnected (read failure) Jul 18 13:10:12 mint last message repeated 5 times Jul 18 13:10:12 mint last message repeated 4 times and broadcast messages like: Communications with UPS mintups at mint.phcomp.co.uk lost 30 seconds later: Communications with UPS mintups at mint.phcomp.co.uk

Hi, I am trying to categorize the network traffic and to send it out across two different providers. For this I mark the packets in the firewall (in the PREROUTING chain of table mangle), and then use another routing table for the marked packets, which has a different gateway from the main routing table. Basicaly I am following the cookbook example in this page:

Hello Routing Gurus ;-) I''d like to know if it''s possible to make a routing decision for pakets originating from a specific port of the local machine without using ipfilter/iptables to mark the pakets. I read about the tc filter stuff but that seems only to be able to sort the pakets to a different queue on the same interface and not choose a different interface for example. Is

Hi, I may be wrong, but I suspect a bug in dovecot deliver when using quotas. I've put some mails into a mailbox and then reduced the quota, to have the mailbox be over quota - here's the quota informaiton: [...] 2 getquotaroot INBOX * QUOTAROOT "INBOX" "" * QUOTA "" (STORAGE 880 5) 2 OK Getquotaroot completed. [...] When I have a setup with quotas only

Hello, I wonder if someone could use the TPROXY with Shorewall and transparent Squid  with using the routing rules on shorewall (tcrules) for hosts / networks (LAN) with multiples providers (WANs) directly from the internal network on port 80 (with TPROXY transparent squid or REDIRECT). On this issue, the routing rules is not work propertly because the source is the

Hello everyone, I was wondering how i should do destination routing. I now do # ip rule add to x.x.x.x table some_table for each address i need. I was thinking about fwmark option. The problem is that routing decision is made after PREROUTING and not POSTROUTING (name obviously sais that :)) and i need to use -o. In OUTPUT this marking can''t be done. I made this conclusion by studying

Hello all, Can anyone recommend a good book which thoroughly explains QoS from a Linux perspective? Something with TC examples & the like. I''ve looked at the following: http://www.amazon.com/gp/product/1580533418/qid=1148368189/sr=1-2/ref=sr_1_2/102-2819973-6353768?s=books&v=glance&n=283155 Engineering Internet QoS. Thanks.

Hi all, I am wondering if anyone can help me to resolve a problem. I am trying to use tc command in linux to drop udp packets of specific diffserv value.

Hi, i have just migrated from courier-imap to dovecot. im using it with vpopmail, the pop service is working ok but the imap service for imp webmail is not writing the quota information to the maildirsize file, as recommended in the docs, i have this in dovecot.conf : plugin { # Quota plugin.

I would like to route ssh in my network via DSL2 and all other trafic via DSL1. So far I menaged to do it for LAN2 but there are still WLAN1,LAN3 and LAN1 to go. On all routers I added table "pilicka" with rule for fwmark and I fwmarked ssh. # ip rule show 0: from all lookup local 32765: from all fwmark 0x3 lookup pilicka 32766: from all lookup main 32767: from all lookup

Hi all, I have 2 ISPs on a Linux router and a local network with one Linux server and many windows. The local network is masqueraded. I want to give access to port 25 and 80 of my server from any incoming request (i.e. from my 2 ISP). I have made a DNAT translation, witch work but the outgoing answers are not routed correctly. Of course, the de-SNAT process is done before the routing process. So

Hi list, I''m new to this list, I just subscribed because I have some ackward about IPRoute2. First, while playing with NetFilter'' "MARK" target, I met a weird behaviour once I tried to use this marks in the RPDB : the packets where successfully marked, but it seemed that RPDB didn''t succed in matching them (for those who already know the answer, I only used

I made a script to test if in a moultiple gateway setup all default connection are up, regardless of the fact that that gateway is the default gw. Suppose adsl1 and adsl2 are present, and all traffic goes by default to adsl1, and you want to test if adsl2 is ok. 1. I use mangles from iptables to mark icmp packets to some test machines 2. I set up a routing table for each adsl 3. I use
