Re: [Engine-devel] Root password to add Host

Please reply to 'all'. When you login as admin you should be presented with Text User Interface. Within this interface there should be options on the left and a dialog on the right. At the left you should see 'ovirt-engine' or similar option, when selecting it, you should see on the right an input field of address of the ovirt-engine server, specifying the engine address and selecting apply will initiate registration into the engine. Once registered, you should see the host in the engine, select it and click on "Approve". Another option is to specify password at the same dialog without filling the engine address. This password may be used as the password withi the 'Add Host' dialog.

You cannot do this via agent by via the TUI of the ovirt-node.

[Engine-devel] Root password to add Host
by Florian BRUSCHET 30 Apr '13

30 Apr '13

Hi, I try to add Host from oVirt Engine Web Administration, but it asks me to give a Root Password (It's not the same that i used to log in admin on the Node). Do i really need this Root Password? Because i can't have it and i don't want to change it by using single mode... There is an other solution to add Hosts? Thank you, Florian BRUSCHET

[Engine-devel] enable column resizing on all sub-tabs?

Vojtech[/others] - what do you think about Gilad's comment below? would it be possible / more correct to activate column resizing within the base grid class itself by default (or something similar), rather than enable it separately for each grid?

[Engine-devel] Proposal to make REST API more webapp-friendly
by Vojtech Szocs 24 Apr '13

24 Apr '13

Hi guys, having worked with Engine REST API from web application (JavaScript) perspective, there are things that could be improved to make REST API more webapp-friendly. First of all, webapps are *not* traditional HTTP clients, i.e. they have *not* full control over HTTP processing. There are some standard conventions and behaviors built into web browsers that any REST API implementation should be aware of. -- (1) Don't force clients to use cookies for transmitting authentication information! (or don't use cookies at all) Good explanation can be found at [http://www.berenddeboer.net/rest/cookies.html] Cookies have many disadvantages: * cookie parsing/formatting is not trivial --> extra complexity imposed on REST clients * in addition to Same-Origin Policy [http://en.wikipedia.org/wiki/Same_origin_policy] cookies can be get/set *only* for the given path --> JavaScript running at [http://example.com/webapp] *cannot* get/set cookies from requests at [http://example.com/restapi] * cookies are the primary source of Cross-Site Request Forgery [http://en.wikipedia.org/wiki/Cross-site_request_forgery] attacks --> malicious websites/scripts can forge requests to REST API that will include the cookie, compromising user session Alternative: clients could be given the *option* to use regular HTTP header for transmitting authentication information. For example, webapp could read such (sensitive information) header, store it securely via HTML5 Session Storage [http://en.wikipedia.org/wiki/Web_storage] and implement related HTTP processing on its own, e.g. pass this header for all authenticated requests (instead of pushing this responsibility to browser). -- (2) Straight-forward HTTP Basic Auth has some drawbacks! HTTP Basic Auth [http://en.wikipedia.org/wiki/Basic_access_authentication] over (non-secure) HTTP connection means sending user credentials (username/password/domain) in easy-to-decode cleartext, i.e. the value is *not* encrypted or hashed in any way. Using secure lower-level protocol (SSL) fixes the consequence, rather than the root cause of the confidentiality issue. Furthermore, browsers typically remember HTTP Basic Auth information (either via browser-specific popup, or via XmlHttpRequest) until the browser window is closed. This means the webapp has no control over HTTP Basic Auth header after it has been set! This is the reason why it's hard to implement "logout" functionality in webapps when using HTTP Basic Auth. Last but not least, HTTP Basic Auth is vulnerable to Replay attacks [http://en.wikipedia.org/wiki/Replay_attack] Someone between client and server can intercept requests and replay them, compromising user session. Alternative: clients could be given the *option* to use more advanced authentication scheme. I've just read an excellent article at [http://www.thebuzzmedia.com/designing-a-secure-rest-api-without-oauth-authe…] which describes easy yet secure authentication scheme inspired by Amazon Web Services REST API authentication [http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html] The idea is simple: collect auth information, hash (sign) it with a private key, and send everything to server. To guard against Replay attacks, just provide some timestamp to enforce request expiry after some time (say, 5-15 minutes). Easy and simple! -- (3) Support JSON for resource representations! I think this is pretty much obvious. XML has no real advantages over JSON. JSON, on the other hand, has good support in webapps (JavaScript) and maps directly to common data structures (i.e. string, number, boolean, and so on). >From webapp perspective, it's much easier and natural to use JSON than to parse/format XML documents. Alternative: clients could be given the *option* to use JSON, in addition to XML representation. -- Vojtech

[Engine-devel] UiCommon models in UserPortal - note about optimization logic
by Vojtech Szocs 24 Apr '13

24 Apr '13

Hi, recently we faced an issue [1] where UserPortal UI refresh optimization logic [2] interfered with direct UiCommon model updates. The optimization logic compares freshly received data with existing data and doesn't trigger UI refresh when there's no change. This inherently implies that UiCommon SearchableListModel shouldn't manipulate its item data directly, or it risks the situation when the optimization logic thinks there's no change (data retrieved from server matches updated item data). (Possible improvement: add "dirty" flag to item model type (UserPortalItemModel) that would be called when UiCommon SearchableListModel does direct item manipulation.)
